How do you know it's wrong? Different from DG stuff by a few frames but that does not a bug make in either of the tools.

I have noticed that all the mkv one has been automatically ivtc'ed, don't know where that process came from. Changing their frame rate to 24000/1001 will change the video length similar to the dg one.

Maybe you want bs.VideoSource(rff=True) because rff defaults to False.

You are right, with rff=True, BestSource matches DGSource.


bs.VideoSource(rff=True)

DGIndexNV -> dgi -> load with DGSource:
24:09.248

DGIndexNV -> demux m2v -> mux to mkv:

frame: 43434 (progressive)

DGIndexNV -> demux m2v -> mux to mkv -> BestSource:
