Yes, you're right. The fade start is based on the video duration, so with a shorter track the fade-out lands after the music has already ended. Taking the shorter of the two durations for the fade start and letting apad fill the rest is the cleaner fix. Thanks for spotting it.

Thanks, that's a good catch. The script only checks r_frame_rate right now, so a variable frame rate phone clip could slip through. Comparing it against avg_frame_rate and flagging any mismatch is a cheap extra check, and it fits right next to the ebur128 pass that's already there.

Thanks for the detailed suggestions. I'm on the MixVio team. Sampling at subtitle cues and checking a crop of the active panel are useful ways to extend the example. The fixed timestamps in the post are specific to that clip, and the safe-zone sheet is a visual review aid. Glad the idea of keeping a QA sheet beside each export was useful.
