Bug ID: 384793
Summary: kdenlive does not preserve normalization gain on
save/load or render
Product: kdenlive
Version: 17.04.3
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: mag...@minimum.se
Target Milestone: ---
Steps to reproduce:
- Start kdenlive
- Add clip "music.mp3" and "video.mp4" to your project. (You can download these
exact files from https://utby.minimum.se/index.php/s/7cBpBNob6xaDXdA ..
although I suspect this bug has nothing to do with these files)
- Put music.mp3 on track "Audio #1"
- Put video.mp4 on track "Video #1"
- Apply effect "Audio correction" -> "Normalize" to video track
- Note that the normalization works, and is by default set to 100% gain.
- Sound of ocean waves are amplified as expected.
- Save project to a new file, quit kdenlive.
- Start kdenlive, load project.
- Observe that the audio of video track is now "muted" when you play the
project. This is because kdenlive adjusts the gain to 0% when it loads the
project, even though it was saved as 100% gain.
The same thing happens if you render your project. E.g, apply an Audio
Normalize effect, render movie and the output have muted video audio, even if
the audio is there when you play it through kdenlive preview.
