The progress bar cuts off prematurely when trimming the video

[nkyess]

When using FFmpeg to trim a video, the progress bar reflects the input file; however, FFmpeg actually completes the task before the progress bar finishes, causing the bar to cut off prematurely.

This is because the duration of the input file is used to determine the progress, which will be incorrect if the output file will be shorter than the input file. The recently added duration_override option (documented here) might fix this issue, if you know and specify the expected duration of the output file.

Do you use -ss and -to, or -t?
