Hi, issue is with keyframes, specifically the gain filter on an audio track in this case, and how they behave when splits are made to the audio clip after there has been an overlapping crossfade transition with an earlier audio clip.
I’ve observed that when the audio clip is split anywhere after a crossfade transition, any keyframe points on that clip jump forward by the amount of the transition.
In my case, the overlapping crossfade transition is 2.4 sec. So when I make any splits to the audio clip afterwards, the keyframes all jump forward 2.4 sec.
I first noticed this when making ripple-all cuts to some video clips, and noticed my gain keyframes were off.
Through chat-gpt led experiments, I realized the shift was relative to the transition length.
And even removing that transition now bumps all the keyframes forward by that amount.
Good luck, shotcutters!
