This is my second post... 11 years after the first one!!
I have just started experimenting with this new mkv format that includes DV to specification, having done (like many of you) mkvs in the past with the DV layer included as a separate stream.
I want to report here a strange thing that I noticed, which I don't know if it matters.
My "old" Fast & Furious: Hobbs & Shaw kv contains two video tracks, a base layer of 195,520 frames and a DV layer which is - of course - the same length of 195,520 frames.
I created the new mkv with MakeMKV 1.15.4 and this turns out to contain a single video track of 195.520 frames, everything ok.
At this point I tried to see what happened by extracting with eac3to (which I have always used before) the video track with the DV included.
This is just out of curiosity, not with a specific purpose.
What caught my attention is that eac3to reports to me in the logs that the length of the video track is 391.001 frames.
I understand that eac3to cannot distinguish the two layers, and therefore incorrectly reports the total ... but this total should be 391,040.
There is a difference of 39 frames.
So my doubt is ... is it an error of eac3to, or actually 39 frames of the DV layer have been lost?
Is there any way to check this?
