We are aware of a lag in certain situations as you state. As Camilles
pointed out, there is a possible fix if you can manage to compile it:

Feedback is appreciated.

Could you please compare with the daily flatpak build please? I suspect it
could be a packaging issue. Here are the instructions:

Add the kde flatpak repository (if not already done) by typing:
flatpak remote-add --if-not-exists kdeapps --from
https://distribute.kde.org/kdeapps.flatpakrepo

Install kdenlive nightly with:
flatpak install kdeapps org.kde.kdenlive

Use flatpak update to update if the nightly is already installed.
Attention! If you use the stable kdenlive flatpak already, the *.desktop
file (e.g. responsible for start menu entry) is maybe replaced by the
nightly (and vice versa).You can still run the stable version with:
flatpak run org.kde.kdenlive/x86_64/stable

and the nightly with:
flatpak run org.kde.kdenlive/x86_64/master

(replace x86_64 by aarch64 or arm depending on your system)

Hi

I have been working on a quite big project recently in Kdenlive with 
hundreds of clips and a timeline over two hours.
I have noticed some problems in this project that didn't show up in my 
small projects before.
First, in a big project like this, the spacer tool has a significant 
lag to move items on the timeline, probably because the operation is not
asynchronous. It would be good it it moves the items right away and 
shows a progress bar to the user to wait in order to be more user 
friendly.


You can join the discussion on this topic at 
https://bugs.kde.org/show_bug.cgi?id=414006


Second, when starting to render the project, especially with HEVC 
profile and medium speed preset, the job queue shows "Waiting" for a 
very long time, even more than 6 hours.
You think it's not doing anything, but it's working the CPU and adding 
to the output file size. I finally canceled a job after 8 hours to 
find out that the render was almost done, the vide was playable near 
the end of the file.


I haven't found anything related to this in the bug tracker. You can 
check at https://bugs.kde.org/ and open a new issue if none matches your 
concern  (you can find some infos  at 
https://kdenlive.org/en/bug-reports/  )


Cheers,

Kdenlive issues with big projects

[Mehdi Haghgoo]

Hi
I have been working on a quite big project recently in Kdenlive with hundreds 
of clips and a timeline over two hours. 
I have noticed some problems in this project that didn't show up in my small 
projects before. 
First, in a big project like this, the spacer tool has a significant lag to 
move items on the timeline, probably because the operation is not 
asynchronous. It would be good it it moves the items right away and shows a 
progress bar to the user to wait in order to be more user friendly. 
Second, when starting to render the project, especially with HEVC profile and 
medium speed preset, the job queue shows "Waiting" for a very long time, even 
more than 6 hours. 
You think it's not doing anything, but it's working the CPU and adding to the 
output file size. I finally canceled a job after 8 hours to find out that the 
render was almost done, the vide was playable near the end of the file. 

I hope these are good suggestions and bug pointers for future releases. 

Here are my system info: 

OS: Fedora 34Kdenlive: 21.11.70 AppImage
Best regards,Mehdi
