Description Bloom Kitty 2019-01-29 13:58:52 UTC

SUMMARY
If the same file is used in a group multiple times and I try to apply an audio effect, it shows the visual representation, but is only applied to seemingly random clip(s).

STEPS TO REPRODUCE
1. Import one video file (I used an mp4)
2. Add into timeline (Video 1)
3. Cut it several times (I did it with a custom shortcut)
4. Select all clips and group them
5. Add a fade out (Drag&Drop or context menu)

OBSERVED RESULT
The effect applies only to one of the sequences, even if the editor shows it on all clips.

EXPECTED RESULT
The effect should apply to every clip in a group.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 18.10

ADDITIONAL INFORMATION
OpenGL Version: 2.1
The input file was 640x480 60fps, while the profile was 1920x1080 25fps

Just noticed that Nextcloud's webplayer doesn't have audio (at least on my machine), so you'll have to download the videos first to hear it.

The uploaded file are not available anymore. You can attach the file direct in this Bugtracker. 

I tested with a clip according your steps and it works in AppImage 18.12.1b and Windows 18.12.1 version as expected. Make sure your profile meet the footage size.
