Blu-Ray to MKV with Megui

[Patrick Bateman]

I've read multiple guides but I can't seem to find one that does exactly what I want, even though what I want is quite typical. Blu-ray -> MKV. The problem is that Megui keeps making 15MB mkv files that are completely useless.

This is what I'm doing:

With AnyDVD HD running I open Megui and with the avisynth script creater, I input the main movie .m2ts file, crop, analyze, and create the script, then use the DXVA HD Extra Quality preset and start the job. 2 jobs added, one analyzing, the second makes the 15MB file.

Previously I tried using TSMuxer, but whether I remux or demux and proceed from there, I get the 'No video sequence header found' error.

P.S. I noticed that DXVA HD Extra Quality uses only 1000 bitrate. Isn't that very low for an HD movie?

Hi!

The simplest "one-click" solution (does NOT require AnyDVD HD - or any other program) is to use (presently freeware) "MakeMKV"...

1. If you're encoding from an MPEG-2 or H.264 video stream in the M2TS file(s), use DGIndex or DGAVCIndex to create a d2v or dga file and then open that in the Avisynth script creator. Use DirectShowSource (e.g, loading the M2TS direct in the AVS Script Creator) if you have a VC-1 video stream. DGIndex and DGAVCIndex will also demux your audio and put the correct delay value in the filename. You can also use eac3to to demux and convert your audio, check the eac3to thread for usage instructions and a download.

2. DXVA-HD Extra Quality is of course fine for 1080p or 720p content, but that bitrate is way too low to create a good looking video. Try using the x264 "Constant Quality" function and set it to be somewhere between 20 and 24. That will give you a good-looking encode as far as bitrate and can help you figure out what to pick for a 2-pass bitrate if you need to hit a predefined file size. By the way, the MeGUI Bitrate Calculator is pretty good.

Thanks Inspector.

I tried using DGIndex before but something happened. I can't quite remember. Either it said 'No video sequence header found' or something else. I'm not home now so I'll try it later. I'll also give DGAVCIndex a shot. You think that was the issue though? I assumed that it would have given me an error if it wasn't capable of accepting .m2ts directly.

Edit: oh I see. The video was encoded in h.264 so I'd have to create a d2v file, right? Hope DGAVCIndex works then because otherwise I have to deal with the 'No video sequence header' issue because that is indeed what DGIndex says.

DGIndex is for MPEG video streams which is why it won't help with your file. It opens m2ts files because they can contain MPEG-2 streams. DGAVCIndex is the one you want for h264 (creating a dga index file).

Do you want to re-encode the video though, or are you just wanting to remux from m2ts to mkv?
