Quick, dumb question with probably a quick, easy answer. Probably belongs in Newbie Discussions but, hey. Video Conversion. That's what I'm up against. Got a Bluray that was unfortunately created as VC-1 (or more like lazily brought over from its HD-DVD roots) and I need to change it to H264.
Standard procedure seems to be to go with MeGUI but that program refused to correctly bring up a preview of my VC-1 video, and would shortly thereafter crash. Seems this is a common conundrum, and sometimes no amount of fiddling with Avisynth, ffdshow, Filter Tweaker or anything would fix it, as indeed it didn't in my case. Fortunately, I found another program that seems a little further along in the user-friendly direction by the name of AutoMKV. Unfortunately, none of its built-in profiles use "high profile" or "level 4.1" or other items even I can recognize as being standard for encoding for Bluray. And I don't know all the command line tricks for situating such things. ;p
So I guess that's about all I need. A full command line that ought to get the most out of x264 without exceeding or missing the Bluray spec. I'll be shooting for 2-pass at 25Mbps or so. Thanks.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

http://www.x264bluray.com/home got a bunch of examples for blu-ray compatibility, to boost the quality a bit you can choose slower presets, like placebo,...
Bu this will probably not fix you main problem which is that libav can not decode interlaced VC-1 properly, you therefor would need a decoder application to decode the vc-1 content and feed x264 with the decoded output.
Typical ways are:
1. Avisynth + DGDecNV ('forced' donation ware, meaning you have to donate to use it). Pro: normally works; Downside: costs and requires a NVIDIA card
2. Avisynth + DirectShowSource. Pro: Free, Downside: problematic to get it working on some systems (this you figured out form what I'm reading )
3. mencoder + DirectShow Interface. Pro: Free, Downside: requires special wmv decoder libraries in the codecs folder of mplayer
-> all of these three methods can work but need some additional reading (personally I use method 3 and Hybrid as a gui; meaning: I install Hybrid and the 'Binary Codec Package' provided on the mplayer homepage)

Thanks. Looks like just what I was after.
Hmm.. It's possible I'm missing something here, but actually the Bluray I'm dealing with is definitely progressive at 23.976fps. In fact I can't really recall more than a handful of Blurays having been authored as anything else. Interlaced VC-1? Yikes.
AutoMKV has no problems previewing the video (unlike MeGUI which fails and then crashes) so I am not anticipating any further need for semi-esoteric app combinations. -
This is the second time I've seen MakeMKV referenced as being able to facilitate (or perform) the re-encoding for me. But if it can do more than rip discs and make MKVs from them, anything else is hidden very well. That said, I never knew it could stream video either, so maybe I'm just blind. ;p
