Hi Harald
Thank you for the feedback/issue collection. I put the points into our
refactoring issue pad. I’m collecting now info for solving the audio
problem. You are not the only one.

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!
Best regards,
Harald
