Short description of error
A scene strip (60 frames) longer than own duration (30 frames), when soft cutted at end frame, Blender makes a second strip from the cut to the end, but the main strip is not cut. So, they are overlapped (supposedly impossible in VSE). Main from 0 to 60 and new one from 30 to 60, both in same channel.
By cutting some frames before or after end scene frame, behaviour is correct.
Exact steps for others to reproduce the error
- Press K key to soft cut strip in frame 30.
- Select strip from the left and move vertically.
