Description timothydrewfilms 2019-04-25 08:15:38 UTC 
SUMMARY
When two individual clips are grouped on the timeline and one is trimmed, the other remains at the same length and has to be manually trimmed.

STEPS TO REPRODUCE
1.Add a video file to the timeline. 
2.Add an audio file to the timeline. 
3.Group These clips together.
4.Use the trim handles on the video or audio clip to resize one of the clips within the group. 

OBSERVED RESULT
Only the clip being trimmed is affected instead of the entire group.


EXPECTED RESULT
Both Clips are trimmed simultaneously.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro Linux, Kernel 4.19.32-1-MANJARO 
(available in About System)
KDE Plasma Version: 5.15.3
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2

ADDITIONAL INFORMATION
This also applies to the original audio from a video clip. Without modification, when a video clip that contains audio is added to the timeline, when one clip is resized, both will be affected. If the clip is ungrouped from its audio and regrouped, the clips will no longer be simultaneously resized.

Hello,
The behavior you observe is intentional. Custom groups can be arbitrary, hence it would not be sensible to apply the same trimming to all the objects of a group simultaneously (in some cases it's not even possible, consider the case where two consecutive clips are grouped)

If you mistakenly ungrouped audio and video from the same clip, you can right click on the video clip and choose "split audio". Make sure there is room on the audio track for the audio clip to be inserted.
