not yet a review.
noticed an issue on macOS.  to reproduce, open a clip from the ticket, hit "play" and then drag the position slider someplace else.
in the master branch, I see these in stderr:

2024-08-06 10:19:04.010 java[52568:1934744] CMTimeMakeWithSeconds(159.122 seconds, timescale 1): warning: error of -0.122 introduced due to very low timescale

with this change, I see an exception in com.sun.media.jfxmediaimpl.NativeMediaPlayer:1530 because VideoResolution is being constructed with width=0 and height=0
