On a 4 hour long clip (1280×720-25fps-32KHz mono) I have done some color grading + some cropping and resizing with a still as background, I have done the export scaling up to 1920×1080 keeping the same codec with no audio.
Once done, I imported the export back into the project and the clip is shorter.
I tried to figure out what I could have done wrong. I remember that I add a problem at the beginning of the session with a 24fps timeline while I already had started the edit, I remove all media then pass the timeline to 25fps then Ctrl-Z to reinsert my media, might this be the cause of the problem ?
To check I open a second project, set the timeline right at the beginning then imported the original clip, the duration on both timeline are identical but I have something weird thing happening on the first project: my playhead being at the end of the clip I have a timestamp of 04:51:20:06 but using the arrow key to move one frame down, the timestamp jumps down at 05:03:38:13.
Is that related to my manipulation with fps at the beginning of the session do you recon ?
I know changing the framerate after having started the edit may bring some issue. I found that trick to remove all media, change the timeframe, then Ctrl+Z to reinsert them, worked, but I doubt now. I guess I’ll redo the whole project new but as it took 4h to export, I’d like not to do the same mistake.
Thanks for your input.

Older versions did not handle mixed frame rates in the same project. Also big red flag having audio set to 32khz not 48khz. I don’t know how this is possible but the sample rate might be an issue to duration as well. Seems like you have a few variables that make it hard to guess the nature of the problem
