Bug ID: 430093
Summary: Webm high quality worse with Quality at highest
setting (recent regression)
Product: kdenlive
Version: 20.08.3
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: ericsbinarywo...@gmail.com
Target Milestone: ---
SUMMARY
Created a Webm with quality slider all the way to the right and the quality
looks horrendous. Very pixelated. This wasn't happened a few days ago before I
updated to the latest. This is on flatpak so I don't know if the change is from
kdenlive or the ffmpeg in flatpak, but the issue kind of seems similar to what
was mentioned https://bugs.kde.org/show_bug.cgi?id=357153, but that's a super
old bug. So I think this is a regression or a change in hw ffmpeg is
interpreting the slider.
I put critical because no one wants to wait 2 hour for a render to end up with
a shit quality video.
STEPS TO REPRODUCE
1. Setup kdenlive with your video
2. Tell it to render webm
3. Set quality slider to the highest setting
4. render
OBSERVED RESULT
Very, very splotchy video with bad quality
EXPECTED RESULT
Really awesome video with great quality
