Can't get to first base because of MKV input file requirement #139

Closed muesic closed 2 years ago

muesic commented 2 years ago

I have thousands of *.dvdmedia main movie rips made via MacDVDRipper Pro (MDRP). Those files are essentially just standard DVD VOB structures. I can compress these in HandBrake, however I think I like your compression tools better :-). The issue is that HandBrake can natively accept these VOB structures and compress them without issue, but in order to use other_video_transcoding I need to first go through an annoying VOB to MKV transcode. I tried MKVToolnix but it yields a really high percentage of MKV files with audio/video sync issues (the author knows about it but has said all VOB development ceased eons ago). I also tried MakeMKV and, while much better, it still has audio/video sync issues. I don't know of any other software on the Mac that can transcode VOB to MKV. As a result, I can't use other_video_transcoding :-(

For a given other-transcode command line, is there an equivalent set of options I can transplant into HandBrake so that I can compress my 20TB of VOB rips?

@muesic Sorry to hear that but thank you for liking my tools.

The DVD directory structure format with its VOB and other indexes has become an obsolete format. You're correct that HandBrake is one of the few tools that still support them. VLC, for playback only, is another.

I don't really know what an equivalent set of options might be since I no longer use HandBrake.

Which video and audio encoders were you planning on using? Because the ratecontrol formulas in other-transcode are tailored for particular encoders.

muesic commented 2 years ago

For the video encoder I'm planning on x265, and I'm just doing a pass-thru on the best audio track (5.1 if available, else stereo/mono).

Also (and this doesn't have anything to do with this thread) I sent you an email on 2/2 but you never responded. I was wondering if "me" at your domain_name dot com was correct (I got that from your website somewhere)

@muesic My apologies for not responding to your email. Things were a bit hectic at home that week and I simply forgot.

I don't actually do anything special for the x265 encoder other than choose a target bitrate and set the VBV to default values. I thought you were using a hardware encoder which is really what other-transcode was designed for.

So, I recommend you just pick one of the default presets in HandBrake and use that. For x265 it will probably work just as well.

I hope that helps.

muesic commented 2 years ago

OK - thanks anyway. I guess I'll just run with HandBrake then.

@muesic No problem. It never hurts to ask.
