System Information
Operating system: Linux-5.4.0-104-generic-x86_64-with-glibc2.27 64 Bits
Graphics card: GeForce GTX 780/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 450.172.01

Blender Version
Broken: version: 3.1.1 Release Candidate, branch: master, commit date: 2022-03-21 13:47, hash: fc0a07da29
Worked: version 3.0.0

Caused by e49bf4019b

Short description of error
Cutting a strip with keyframes in the VSE deletes the keyframes from the original (left) strip.

Exact steps for others to reproduce the error

  1. Make a strip in the Video Editor (I originally used video strips but can reproduce with a straight color strip).

  2. Keyframe opacity in a few places.

  3. Select the strip and cut it into two using K, somewhere between the keyframe locations.

  4. The right-hand strip retains the keyframe information, and the left-hand strip deletes the keyframes.

  5. This worked in Blender 2.93.0 Beta, and in Blender 3.0.0.

  6. Also NOT working: Blender 3.1.0 and blender-3.2.0-alpha+master.b9123b806fc4-linux.x86_64-release both have the same problem.

  7. The problem seems to not be confined to opacity, I tried keyframing cropping and the same issue occurred.

Thanks for the report.
It looks like a regression and I didn't find any duplicates so I'm setting it to high priority.
Introduced somewhere between 34d424fd64 and b47a1867e8 (Maybe {eddad4e9a1}?)
I will bisect...

There will be. In the patch mentioned above one of the items was:

  • Remove function SEQ_dupe_animdata, do curve duplication explicitly in operator code

The code that was removed would need to be put back, or the problem "in operator code" would need to be resolved. I am confident that this will be achievable.

I have incorrectly included patch for corrective 3.1 release so it wasn't included.

You can use latest alpha build from https://builder.blender.org/download/daily/ where fixes are applied daily. Sorry for inconvinience.
