System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA RTX A6000/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 537.42

Blender Version
Broken: version: 4.0.0, branch: blender-v4.0-release, commit date: 2023-11-13 17:26, hash: 878f71061b8e
Worked: (newest version of Blender that worked as expected)

Short description of error
if I use the default split it works, but if I try after splitting to retime it, it stitched from the clip starting time not from the clip start frame

Exact steps for others to reproduce the error

  • make a split (K) in the audio file
  • Try to retime the new strip, the retiming starts from the begging of the audio not from the start frame of the clip

first issue: when you try to hold split any audio strip the time of the new strip changes

Is this the same as #114951?

Unable to confirm the retiming bug

Well actually, I can confirm that some frames are repeated after retiming the strip (i.e. speed is reduced). Is this what you're observing too?

watch the video and you will see that when retiming the splited clip, it does not stretch from its new start time, rather than it stretched from the real start time before splitting it. which is not logic

Indeed, can confirm. Though this do not happen if we select first key of new strip and then retime with the last key.

I would guess, the cause is same as in #114951 - I wanted to make SEQ_give_frame_index() work for sound, and it does, but seq->anim_startofs is for some reason treated separately over whole codebase. Will probably keep it that way for now and hope it will go away soon.

I was quite a bit off with my guess. Fortunately, the solution seems to be much easier, than finding the problem :)
