To see if that is a packaging issue, please try with the AppImage from

The problem is the wipe-effect on V4 which is set to V3. I think the

Or you change Wipe to “Slide” with Start in the center and zero

I'm experienced with kdenlive, using it off and on for various
projects over the past decade, always on Linux/Debian. Last time I
used it was May 2022. I had not upgraded my Linux for several years
until July 2022.

Today is my first use of kdenlive after the Linux upgrade, which I see
(per the About box) was upgraded to 20.12.3. I also checked my
kdenlive from the Linux command line, and I got a message that I have
the newest version, 20.12.3-1. However, the kdenlive website lists
later versions, up to 23.04.0 (2023-04-20)... dunno why my system says
I have the newest. I tried to re-install but it refused saying I have
the newest.

In any event, I recorded a video today with a camera file (MTS) that
has a low quality audio track. On a separate audio device, I recorded
an audio file (WAV) from a good lapel microphone. Both files play
normally with VLC.

When I bring these files into kdenlive, and drag them into track(s)
and then play, the video displays properly in the monitor. However,
the audio is BARELY AUDIBLE in both files, even when I maximize my OS
volume. If I go to Settings/Configure-Kdenlive/Playback and set the
Preview volume to its max (200%), I can hear a little better and
without distortion. (If I display the Audio Mixer, and maximize the
channel and master, it distorts horribly, so I'm not doing that.)

When I render a little zone and play it (forgetting to turn down my OS
volume), it blares loudly and without distortion. So, the rendered
result is okay.

It appears that something is severely attenuating the preview/monitor
volume. Please advise. Thank you.

Hi Ben, hi all,


Hi Julius,


I did a little research about this recently and unfortunately
it seems to me as if there is not really a solution on the
Sphinx side. One need to have separate build dirs for every
language and it copies all static files (css, js, images,..)
to every build dir. That's just how it works :-/ (Correct me
in case anyone knows I am wrong).
However we can of course try to solve this on our and and make
our deploy tools smart in a way that they keep only one
version of each image file and replace the others with symlinks.
It should be more or less easy to detect images that are
translated since they follow the pattern |filename.de.png
where "de" is the language code, so this image would be
special for German, while for all other languages filename.png
is used.|


I had a very strong feeling that would be the case (very much
seems that Sphinx actually doesn't have proper i18n/l10n support
and it's been hacked in / bolted on later).

My initial thinking on a quick and (somewhat) dirty solution to
this had been to merge all of the image files into a single folder
at top level and then symlink that from each language.
Knowing that translated images actually have a separate filename
convention indicates that this might just be crazy enough to work.

Thoughts?


I hope that helps so far. I might be able to look into this,
but probably not very soon so if anybody else can work on this
I am more than happy.

Cheers,
Julius

Hi all,

For some time now it has been known to me that the system
for generating application documentation websites using
Sphinx with l10n support has had issues with duplicating
data - particularly images.

That leads to the following outcome, where aside from
sites that we expect to be quite large (like www.kde.org
 and api.kde.org
) all of the application
documentation sites are quite big as well:

root@nicoda /srv/www # du -h --max-depth=1 ./generated/ |
grep G
2.3G    ./generated/cutehmi.kde.org 
3.7G    ./generated/docs.digikam.org

2.4G    ./generated/api.kde.org 
2.3G    ./generated/docs.krita.org 
1.4G    ./generated/www.kde.org 
7.9G    ./generated/docs.kdenlive.org

29G     ./generated/

This stands in comparison to the Docbook documentation
site for all other KDE applications:

root@nicoda /srv/www # du -h --max-depth=1 . | grep G
29G     ./generated
16G     ./api.kde.org-legacy
6.0G    ./docs.kde.org 
51G     .

It would be nice if we could please look into some fixes
for this, as it looks like Sphinx is duplicating the
images - once for every language - when that isn't necessary.
I could understand if the screenshots were updated as part
of the translation, but it looks like they're not in the
majority of cases - below being just a sample:

seem that hard to implement, but very effective and useful. We have
many reports about rendering crashes without useful info to fix or
debug the cause.


Hello,

I agree with what stated before :

3) for tests : we should write more (including some UI but not with
virtual display), but not investing years focusing on coverage, just
adding little by little

2) for project test suite, but can run only before release by beta
testers

1) for crash backtrace, trying to figure out how to dynamically
download debug symbols (can we have something generic like abrt on
fedora, whoopsie on ubuntu ?)
also note that KCrash(DrKonqi) / DrMingw can currently be loaded only
for kdenlive but not melt => for rendering crash info we must plug it
into melt!

Thanks for your involvement, good luck :-)

Hi all,
I continue to believe that the general quality of Kdenlive releases is
one of the most important areas for improvement. I have some ideas
that I think could help, but only limited time to implement them. I'd
like to hear from you all what would be most valuable and should be
done first.

* UI Automation Testing - We can create some UI tests (click menu
item, click button, etc.) for some common tasks.

Pros: Can run tests without source code, so we can test packaged
releases and check for packaging issues like missing dependencies.
Possible to run tests across platforms. Can test UI that the current
unit tests cannot cover.
Cons: UI tests tend to be flakey, slow, and/or hard to write. No code
coverage data.

* Project test suite - We can create a suite of Kdenlive projects and
test that they render pixel-for-pixel in each Kdenlive version.

Pros: Catches when we accidentally break/remove effects. Catches
regressions when we change timeline behavior and clips are shifted.
Helps ensure that old projects will continue to work in future
versions of Kdenlive. Could catch some rendering crashes (e.g. GPU
accel).
Cons: Slow to run. Requires a lot of sample projects + audio/video
files as test cases. Might require some code changes to be able to
script properly.

* Better crash logging - Many of the bug reports do not have a
backtrace, and it's not currently possible to get backtraces for some
release types (AppImage?).

Krita provides a UI dialog to view its log, which also includes
backtraces. The krita log file is also easy to get on Windows.
https://docs.krita.org/en/reference_manual/sharing_krita_logs.html#getting-backtrace

Other areas for improvement include logging what frame a render job
crashes at along with what effects are used during that time. I'd also
like to know how other KDE projects improve the bug reporting flow.

Pros: backtraces make it easier to fix bugs.
Cons: Users need to be educated on how to find and upload logs. May be
difficult to get backtraces in AppImage, Flatpak, Snap, or for the
renderer. Doesn't help catch bugs before they're released.

I think all are feasible to implement, although all would require some
additional ongoing work to be useful. Any suggestions or comments? Any
other ideas that I should look into?

Thanks,
Eric

Re: Kdenlive corruption and rendering crashes

Also, I wanted to extract the timecode at which melt crashes, to give
this feedback to the user, and maybe offer the users to scroll the
timeline to that position so that they can check if there are weird
clip/effect/transition to tweak here.

I like this idea as I see many rendering issues coming from FFMPEG
incompatible clips or the user enables "Parallel Processing" in the
render settings for which some effects are not capable.

Hello Eric,

First, many thanks for your involvement and efforts to make Kdenlive
always more robust!

Regarding render crash, I had ideas for a long time that I never put
in place...

We are supposed to hold the log from melt process and show it up upon
any problem,
but I'm not sure it is true all the time, and I wanted to better
advise bug reporters to share this log.
I also thinked of increasing melt verbosity level to get more
information from this log.

Also, I wanted to extract the timecode at which melt crashes, to give
this feedback to the user,
and maybe offer the users to scroll the timeline to that position so
that they can check
if there are weird clip/effect/transition to tweak here.

Moreover, we can get crash stacktrace on Linux for kdenlive thanks to
KCrash/DrKonqi,
on Windows we had DrMingw that we had to disable for years
(Craft was held on buggy mingw-gcc-9, now gcc is upgraded we can
enable it back).
But melt doesn't have any crash handler linked,
we could submit a PR to MLT to add an option to link to KCrash/DrMingw,
or any better options (embed a simple signal handler dumping
stacktrace?).

But most users don't run programs with debug symbols,
so we must understand how to make the trace informative later on ?
I have seen fedora's ABRT system automatically getting debug symbols
to generate bug report,
I don't know if this can be generalized through KCrash or any other,
or if it's a task not too difficult on the developers side?

I'm sorry I never found time to learn how to do this and apply these
ideas,
maybe you are ready to dig into this direction?

That's all for now, hope this helps!

Vincent

Is it still affecting you today? The thing about the internet is
that sometimes old posts show problems that have long been resolved.

For rendering crashes, bug #456689 is the latest and was reported on
22.04.2.[0] There are other bugs with a similar symptom, and seems to
be mainly a Windows problem.[1]

More generally, this feels like part of a bigger category of issues
where we have buggy dependencies without end-to-end testing to catch
them (e.g. otio, KF5 Purposes, ffmpeg). Ideally users should feel
confident in upgrading to a new Kdenlive version.

For timeline corruption, the most recent report I found was on Reddit,
regarding 22.04.3.[2] I personally am still using 21.12.3, but don't
remember if I experienced corruption with 21.12.x or 21.08.x. It may
only happen to a small % of saves, but it's a very destructive bug.

Personally, I think Kdenlive has a good set of features already, but
there are opportunities to greatly increase its stability. Open to
ideas and opinions!

Re: Article on Kdenlive and Shotcut in a Swiss magazine

[Eugen Mohr]

Hi Christoph

I'm Eugen Mohr from the Kdenlive core team. Thank you for the link and
the nice article. Yes Kdenlive get more and more stable and we think we
implement features to help the user making great videos. I ask the team
about your 5 "wishes" and here are the answers:

1) and 5) There is already an alpha implementation of openfx and gmic.
https://discuss.pixls.us/t/gmic-for-openfx-and-adobe-plugins/452/114?u=frd.
This depends on the MLT integration as well.

2) OpenEXR: write support recently landed in FFmpeg, so this might be
something possible.
The problem with openEXR files is that they are HUGE so if there is no
way to offload playback to GPU the experience is not very nice. Also
usually they have more than 8bit color depth...

3) Bins: We have a task for that. Please make some details on what is
missing so I can add it to the task.

4) Organizing and commenting features: Please explain more in details
what is missing.

6) Color corrections. Primary and secondary color correction is possible
already. We know it's not the best implementation so far. Let's see if
we can improve it.

Best regards

Re: Kdenlive Website Divi Builder issue -- again

[Eugen Mohr]

Hello Tyson

Thank you for the text update in Chinese. The actual 21.04.0 installer
doesn't delete all files in the Kdenlive folder and the left over leads
to a crash when starting 21.04.0.

Yes this download banner is a "global" page that's the reason why it's
green. It shows up on all language the same. I made the change to a
global page to have it easier when update the version. Then I
implemented a special link "piwi" that the download gets counted so we
can make analysis how many download we have.

The banner is fixed and all download links are working.

Hi team,

I'm very sorry that I ran into some problem with Kdenlive.org's Divi
Builder again today.

When I was trying to edit the newly added red text:

"Windows: Uninstall old version. Then install version 21.04.0."

on the Download page, for some reason it broke The Windows
Setup/Standalone version's download buttons (again!). I did open the
modules look for the new text's location, but I'm pretty sure I
clicked the "Disregard All Changes" button before doing anything else.

I was able to fix the the buttons by using HTML code from a unaffected
button. I have double checked the links to make sure they are correct
as well. Still, I think the height of all Download buttons look a bit
off now. I can't remember whether they started like this or not before
I touching the page. I was in a panic.

What I've learned this time: 1) Wordpress's Revision system did not
work for Divi Builder for some reason. 2) For the Download Section
specifically, things can't be translated inside of it and all
languages share the same stuff. 3) I must switch to Code mode first,
then refresh the page, and only then will Divi display the correct
HTML code. Otherwise it will display some interpreted codes that
produces the exact result like when I broke it today. I wonder if they
are connected.

Please have a look at the situation and make additional fixes if
necessary.

My deepest apology again for the inconvenience!

To my surprise, although I have only changed the button texts on

Not only that, I now can't edit anything in Divi Editor by clicking

Hello Tan

Sorry for late reply. Thank you for your contribution. It would be great
for a Chinese translated homepage. I think the best way is you send the
translated page on Word (or similar program) so we can update the

click direct to the download page. A starting point could be the
download page. You can take the German page as a guide for what could be

Hi there, development team of Kdenlive

It's been a while since I was involved with Kdenlive. Back then, it
was only a hobby, but recently I have started making videos commercially.
I still maintain the Arch Linux kdenlive-git and kdenlive-release-git
packages, of course. It's pretty low effort involved to maintain a
package.

Firstly, Kdenlive is pretty solid, and suits my needs perfectly. There
was some chatter about moving to a different channel for bug reports.
As I am using Kdenlive much more now, I am running into minor
annoyances, and would like to feed that back to the group.

Minor stuff like:
1. The cursor being invisible when adding or modifying text in a title
clip.

2. .mlt clips' sound manipulation being missing. When changing the
speed of a clip, the resultant .mlt file does not have a "sound"
attached to it when dragged onto the timeline. It makes it hard to
mute, unmute or change the volume of a clip.
I have taken to making my own transcode profile, and transcoding the
clips to get at their sound again... but this seems against the whole
non-destructive editing that was a large focus of Kdenlive when I
started using it.

Where would you guys like to have these gripes recorded?

Also, sound seems to have a bit of room for improvement. There is no
equalizer or hiss removal or FFT filter. Currently I am using Kdenlive
to split out the audio stream, then editing with Audacity, then using
ffmpeg to re-mux the sound back into the video clip. Why am I doing it
that way around?

Well, it's not always clear which clips you are going to use in the
edit. Once the clip is all cut up, it's a pain to extract each little
piece and do en-masse sound filtering on it. So, I edit the master
clip's sound, and re-mux it with FFmpeg, and when I re-use the
original filename, Kdenlive does not know the difference, and I have
nice clean sound in every little piece of the clip that is used.

It would be nice if I was just able to export the sound, edit it, then
"merge" it back into the clip, overwriting the original sound.

Kind regards,
Evert Vorster

to have translatable default layout names (see the screenshot attached).

I'm trying to renew this feature with a trivial patch (attached). It does work
somehow (extracts, translates the button labels and actions, etc.), but breaks
the button change logic. Can the patch be enhanced by some of the more
skillful Kdenlive main developers to make the default layout names
translatable?

Thanks in advance for your help.

Best regards,
Yuri

By this way, when in spanish you say «código abierto» (open source) you

Re: Pitch compensation on speed effect doesn't seem to work

[Eugen Mohr]

Hello

The rubberband lib integration into MLT is not proper done so far. You
have to manually do the following:

lib/pkgconfig/fftw.pc rename to fftw3.pc

compile rubberband

compile vamp-plugin-sdk

compile ladspa-sdk

On the end compile and merge MLT again. This should enable rubberband in
MLT which will handle the pitch compensation.

Or you wait until the rubberband integration is done correctly.

My videos depend on having pitch compensated audio for time

exporting the audio, and modifying the tempo in Audacity. I'm really

I've rebuilt mlt from git master, verifying

I've rebuilt kdenlive from git master, completely from a clean tree.

Hallo Candide

The downloaded title clips are stored here:

Hello,

I'm currently using Kdenlive 18.08.2 on Windows 10, and noticed that 
when I go to "Settings > Download New Title Templates" and try to 
install a new template, I'm unable to find it (despite indicating that 
it's installed).


I've searched through the Kdenlive program files to see where the 
installed titles could be saved, but couldn't find them. I noticed 
that the pre-installed title templates were saved in the folder 
"Kdenlive-18.08.2\data\titles", and it seems like the user-submitted 
title templates that can be installed are hosted here: 
https://store.kde.org/browse/cat/335/.


I've realized that if I downloaded the titles directly from the KDE 
Store, unzipped the folder, and copied the .kdentitle files into the 
"Kdenlive-18.08.2\data\titles" folder, the templates appeared in the 
software.


For future releases, would it be possible for the Templates displayed 
in the "Settings > Download New Title Templates" window to be directly 
saved in that folder, as opposed to having to KDE store (as well as 
for the wipes, keyboard configurations, and render profiles).


I would love to create some new title templates to share, and it would 
be a lot easier for people to use them if they be downloaded inside 
the program.


Best,

Candide

problem. You are not the only one.


Eugen

Am 01.12.2018 um 18:44 schrieb Harald Albrecht:


Hi,

while throwing some of my existing Kdenlive projects at 19.04 beta 6 I 
noticed these things:


  * missing effect: frei0r.scale0tilt -- no, this ain't edge crop,
which does not allow repositioning the cropped part. scale0tilt is
one of my essential effects which I need in many of my daytime
projects, for instance, when cropping and placing screen
recordings from mobile devices, PC screens, et cetera over other
illustrations.
  * timeline playback has less performance compared to classic and
stutters much more often. preview rendering simply fails without
any usable information as to why. preview profile is DNxHD 1080p
25fps for FullHD 1080p 25fps project.
  o switching to MPEG preview rendering profile kills kdenlive:
first segment goes yellow -> green, second segment goes
yellow, then kdenlive crashes. terminal output is useless with
only 10982 memory access violation
  * project with only two audio tracks gets a third new audio track A3
named "extra audio": it contains mp4 video clips from video track
V1. Might that be because the source video has a (silent) audio
tracks?
  o By the way: where's the classic disable audio on video clip gone?
  * the audio of timeline playback doesn't work correctly, audio is
"wav" PCM 32bit 48kHz:
  o some audio clips are silent, albeit they contain a clearly
visible audio waveform.
  o some audio clips don't show an audio waveform, but they should
as the clip region in question has non-silent audio.
  o in general, audio waveform is out of sync with the clips in
the timelime and playback: when audio playback is correct, the
waveform isn't, clearly visible that silent parts of the audio
waveform don't match the correct playback.
  * Transitions are almost invisible in the timeline and make them
very hard to spot. Please add an option to bring back the much
more visible classic design: as I work a lot with transitions in
order to compose multiple video tracks, the new layout is a pita
to me.
  * Transition keyframes sometimes end up being shown in the
transition properties with the correct frame positions, but wrong
keyframe "bar" in the properties; that is, while two keyframes at
0f and 12f get imported correctly, the keyframe "bar" shows the
keyframe at 12f sitting somewhere near the middle, but without any
following keyframe. The bar thus extends beyond the length of the
transition.
  * In console I see lots of "couldn't create image from "...png" or
"jpg", however, these image file are fine and correctly shown in
all other tools; does the AppImage contain borked import
filters??? I've seen this problem before with an AppImage, I think
it was 18.04 which was totally unusable due to this issue. For
reference, 18.08 works fine!

Re: Nvidia crash using kdenlive: where to start?

Hi Corey

I would say use the refactoring_timeline branch. The master branch

the Vaapi and Nvidia (Nvenc) acceleration. MLT has v6.12.0 released with

I'd like to make my script work with the AppImage releases, as that's 
why I am using right now (because the automatic crash recovery is a

Re: Windows, crash analysis

[Eugen Mohr]

Kdenlive-17.04.3

Kdenlive-17.12.0

Kdenlive-18.04.1d

Kdenlive-18.08.0

It seems it’s a generic problem as:

0x0005



_INVALID_PROCESS_ATTACH_ATTEMPT 
<https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x5--invalid-process-attach-attempt>_




Hint according Microsoft:

This bug check can occur if the driver calls the *KeAttachProcess* 
function and the thread is already attached to another process. It is 
better to use the *KeStackAttachProcess* function. If the current thread 
was already attached to another process, the *KeStackAttachProcess* 
function saves the current APC state before it attaches the current 
thread to the new process.


0x0094



_KERNEL_STACK_LOCKED_AT_EXIT 
<https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x94--kernel-stack-locked-at-exit>_




Could be a follow up crash of 0x0005

The Kdenlive EXE file has no version number. So I put Kdenlive always 
into a folder which has the version name.

Re: Contributing to Kdenlive

Hi John

If you say “programmed”. What is coming to my mind is hardware. Do you 
have a sound card or video card involved which helps rendering? I don’t 
know if there are some temp files in Kdenlive who stores some 
intermediate steps?


MLT, QT, FFMPEG? I don’t know the software routing from pressing play 
until something happens.

Hey Eugen,

yeah I am already trying to combat the pops by adding fade ins and 
fade outs at the end of every clip, which helps sometimes.


But whenever there is a Slide transition, I can't here a pop during 
playback, but the timeline indicator will halt/stop for a millisecond 
during that transition period in the timeline, and that is exactly 
where the pop occurs in the rendered output.


And it seems that nothing I do, in terms of switching different audio 
codecs, containers, even moving the clips or the transition where the 
pop occurs, solves the problem. Once the pop is there, it will 
continue to come up as if it was programmed at that specific spot.


The only thing that seems to help is lowering the framerate by 
changing to a different project profile, but that completely messes 
the audio up, putting it out of synch etc.


I will try going back to Ubuntu 16.04, maybe it's something about 
Alsa/Pulseaudio on 18.04. Really at the end with my math here.


Thank you for your patience, I really appreciate it

As I don’t see your timeline my guess is that this pops/clicks coming

one audio on each other.


To avoid this make an audio crossfade. On 1 audio track a fade out 
and on the other a fade in.


Audio crossfade seems still on the wish list.

Yes sir, I use Lubuntu 18.04 and Kubuntu 18.04.
I just checked and the clips are ususally 44.1khz 16bit.

The only way I can get rid of all pops is if I render with a 25FPS

50FPS, 59.9 and 60FPS all produce the same pops.

It's driving me so insane omg, I can't sleep anymore.

I assume your audio file is not proper because FFMPEG can handle

Do you have this problem at playback or after you have rendered

Re: Windows, “play” bug with space key

[Eugen Mohr]

Just in Windows:

By start playing in Windows the play head goes always:

5 frames fore -> 4 frames back -> 4 frames fore -> 4 frames back -> now 
it plays forward


It makes like a jitter by ca. 0.5 sec. before it starts playing.

And each time hit the space bar the play head moves 1 frame forward.

If the timeline contains 2 clips above each other (on video 1+2) and

It comes 2 things to my mind:
-    Do you cut the audio at the zero point? In Audition (for example) 
is a function that you can cut only at that point (when the wave goes 
through zero) to avoid clicks.
-    When audio frequency (i.e. 44.1kHz) and video frequency (i.e.

Video rendering is always video frequency driven. This would be a FFMPEG

beginning of an audio track. I have observed that this happens the 
most when two audio tracks are overlapping or a cut has been made at 
the beginning of the a clip.


I have also found that audio pops disappear in the same footage 
disappear when switching from SDL to RTAudio in the settings.


I am using a fresh install of Kubuntu 18.04 with updates and
Mlt and ffmpeg versions all from the Appimage, so this has to be a 
thing in kdenlive or maybe the latest Alsa / Pulseaudio package?


I have tried some stuff suggested in forums such as exporting only 
the audio in wav, but without luck.




I have just uploaded the 18.08.0 AppImage containing the latest MLT. 
Could you check if the problem still happens ?

It is available here:

https://files.kde.org/kdenlive/release/kdenlive-18.08.0-x86_64.AppImage.mirrorlist

Thanks for your feedback.

Jean-Baptiste



Any ideas?

Regards

Hi,



Hello Juku!

Thanks a lot for your contribution and sorry for my late reply. 
Your help is very welcome. I have now merged your contribution. 
Regarding the tests, they need some work and currently don't all 
pass and crash. We need to work on that.


Regarding other tasks, we really need to make a list of UI 
improvements that could be done without too much knowledge of the 
whole code. I will try to spend some time on it tomorrow, help is 
welcome. But basically, if there is any UI related thing that you 
want to improve, feel free to ask and we can guide you if needed.


Best regards,

My name is Juku. I am a film hobbyist and I have been using 
Kdenlive for about 8 years. As I'm also a developer, I thought I 
would try my hand on contributing to Kdenlive.


I have mostly been a web developer so far, so I do not have much 
experience with C++ (except for some tutorials) and I have never 
done any Qt development.


I viewed the "Junior Jobs" section in Kdenlive Development 
Information page and tried to fix #384511 for start ("New project 
window does not fit to laptop screen (1366x768)"). Thanks to a 
hint by Christoph Feck in the comments below that bug, I got it 
fixed and submitted the patch (D14281 
) for review.


Currently I'm having some trouble with the automated tests. Should 
they succeed in their current state or are there some known 
problems with them?


It would be helpful if someone would suggest some other tasks 
which I could start with.


Thanks,
Juku

If the timeline contains 2 clips above each other (on video 1+2) and

After 27 times hitting space and arrow right it appears a time lag

Re: Incredible Render Performance In Kdenlive With NVENC - But 1 Big Problem

[Eugen Mohr]

Am 23.07.2018 um 19:35 schrieb johnar1:
Thanks again, for your efforts! (Ich vermute, dass du ebenfalls 
Deutscher bist, also nochmal danke haha.)
*I have 100% and with absolute certainty figured out what the actual 
problem is.*


I have compiled melt from the latest git available here: 
https://github.com/mltframework/mlt/releases/tag/v6.10.0

I just ./configure and make && make install
I then use this melt executable by selecting it in the kdenlive 
environment tab.


Here is the kicker:

When I use ./configure --enable-gpl --enable-gpl3  to compile melt---> 
NVENC does not --->CPU utilization 100% on 1 core, 20% - 30% on the 
rest, GPU utilization= 4%


When  I use ./configure without these two flags ---> NVENC works --> 
CPU utilization = 100% on all cores /GPU utilization = 90%



Here is kicker number 2:

I originally thought this was a problem with NVENC, but that is not true.

When compiling with --enable-gpl and --enable-gpl3, Kdenlive 
subsequently only uses 1 single CPU core for rendering. (Despite 
having 4 threads selected in the render dialog, kdenlive environment 
and even in the generated render script)


*That *is why NVENC *appears* to not work, because the CPU is not 
being used properly, hence it cannot feed the GPU enough frames. There 
is some GPU utilization


Now I have read that enabling the license also enables a bunch of qt 
modules, and qt obviously heavily pertains to concurrent CPU scheduling.


You'd think that the problem could be solved by simply not using 
--enable-gpl and --enable-gpl3, but unfortunately that excludes the 
libmltqt.so module, which I need for title clips in kdenlive.



So basically, without gpl I get crazy render speeds and almost 100% 
GPU/CPU utilization, but not title clips.
And with gpl only 1 single CPU core is being used for rendering, no 
matter how many times I specify 4 threads, but title clips work.

The only thing you can manually install that is related to nvenc,

Yes it works. It creates a desktop shortcut as well. I tested it on

Even uninstall Kdenlive via "program and functions" works.

Windows, “play” bug with space key

Maybe I found the “root cause” of the “play” bug in Windows.

It has something to do with the Processing Threads in the Environment menu.

Processing Threads = 1 -> start/stop with space doesn’t work. Frame by
