Regarding : B-Frame file opening very slow

[jimmy]

Hello. Regarding earlier thread, not sure if this is related.

https://avidemux.org/smif/index.php/topic,20057.0.html

I may have seen this B-frame warning in the distant past, but it has come up twice recently in win64 Nov 27, 2022 nightly.
Both 24.000 fps blu-rays remuxed to mkv. Choosing yes to the recontruction takes some 40 minutes, which would be fine,
but the result is an unusable jumble. Choosing no, everything seems normal, the reconstruction was certainly not required.

I have no idea if this is expected behaviour, some flaw in my input files, or a program bug. Short sample attached.

Edit to remove sample link.

Presumably VC1 video track. That has always broken timestamps when in MKV. Not sure how to fix – and VC1 is on its way out / dead. Just decline the well-meant offer to restore timestamps.

That is reassuring. Thank-you.

Indeed, the AVC1 blu-ray remuxes I have on hand do not throw up the warning. Cheers.
