MKV and VFR (Again)

[OvejaNegra]

OK:

i have a mkv with VFR (variable frame rate)...
can i demux the video and the audio, recompress both (ogg+x264) and then remux them again in mkv using the timecodes extracted with mkvextract_timecodesv2..... etc???

what about the b-frames??

i made two tests and the result was ok but i´m not sure, maybe it´s lucky.


Second: how can i cut the audio and the video and (YES) the timecode without recompress? (i think it´s imp)

as last choice of course i know i can convert the video to CFR with avisynth but only as last choice..

any suggestions?

BTW, i´m creating a GUI for avisynth, which method is easier/better/recommended for the creation of vfr videos using hybrid DVDs? (with avisynth)

Sorry for my ***** english

Thanks

Cutting a/v can be done by mkvmerge, you feed it a time to start and end (it'll always start at the nearest keyframe) and it'll give you just that chunk, keeping all timecodes intact. And ever since 1.6.0, it's supported v2 timecodes with b-frames flawlessly, it's been a long time since you had to reorder them manually.

You probably already know about this, but I'm not sure if the last question is about this or not:

Thank you for the answer!!!
i can put a time TO START and end in in mkvmerge???
Really??? were??? in "after timecodes"???
You are right about timecodes v2, just that avisynth help is outdated, in the homepage the timecodes without b-frames reordering is mentioned but in the help is not.

Thanks..

Yes i already know about the link you post, just i´m looking for the favorite method used for the DVD/anime encoders/rippers for my GUI.

If you know something about this please let me know...


ThankS!!!

For VFR you may also try timecode files v3. It's way easier to maintain as it mostly deals with zones. Other than that, what you're trying to do is perfectly fine.

And yes, mkvmerge can trim a part of a video.

HEY!!!
The MKV + VFR stuff is working very well for me.

Thankyou all!!!
