just the info if it is VFR is not enough. the first frame could be reported with a shorter frame time and the rest is CFR but the file would still be reported back as VFR. this is a real "problem" BTW. but real VFR is really uncommon.

you could add a tag to force SM. sorry i don't know the name of them but pretty sure there is one.
If there's a lot of "fake" VFR, then that's a problem for sure. But VFR isn't as rare as you think. All of my recent smartphones record VFR video. Sometimes frames are skipped or delayed for whatever reasons... CPU throttling because of overheating, background tasks, who knows. Learned it after many hours of pulling my hair when trying to re-encode my videos using tools that assume CFR.
