x264 re-encoding with MeGUI

[Raffa]

Hi all,

I have an xbox360 and as you know it doesn’t support mkv files. So in this case I can either use GotSend to create mp4 file from the mkv or to re-encode it using MeGUI. But since I want to see the video with subtitle then I must go with the second option using one of the x264 presets available in MeGUI. So what is the most optimal preset for re-encoding an existing mp4 file? I have used the xbox360 fast preset but it takes too much time on my Athlon X2 4600.

Why don't you just re-encode and mux the source to mp4 instead of mkv?

If it is only the mkv container that bothers you, then you can use MKVextractGUI.exe which is included in \megui\tools\mkvmerge. With MKVextractGUI.exe you can demux the mkv-file into h264, aac and a subtitle track and then remux it with the megui-mp4-muxer or with Yamb to a new mp4-file, goes really fast and needs no reencoding.

Thank you all for your reply.

I have tried to mux the subtitle inside the mp4 container but my Xbox didn't recognize it :(

As far as I know, the Xbox360 doesn't support external subs. So I am left with hardcording it..

How to re-encode an existing x264 video for an xbox360???

What container is the h264 video in?

1a.) If the container is mkv use MKVExtractGUI to extract h264 video and audio.
1b.) If the container is mp4 use YAMB to extract h264 video and audio.
2.) Index h264 video with DGAVCIndex.
3.) Create avisynth script file to frame serve the dga file.
4.) Encode using MeGUI Xbox video profile.

I tried doing this with some of my earlier encodes but the demux audio sometimes ended up out of sync when remuxed. Is there anyway to see what the audio delay of a file is so that when we remux to mp4, that it is in sync?

Check the FPS of the source and of the remuxed mp4. I am sure they are not the same. Use something like Gspot or Avinaptic.

Here is my current workflow:

1. Import MKV into TSMuxer
2 Convert MKV to MT2S
3. Use DGAVCdec to demux audio to get audio delay
4. Demux MKV using TSMuxer
5. Import demuxed audio into MeGUI then to MP4 Muxer.

This takes forever. Is there anyway to import the MKV file into MeGUI and pass through the video and just convert my audio to AAC 5.1?

I have a ton of videos done for a client according to their specs (wanted MKV originally) now they find out that their customers request the mp4 format for ipod playback and so they can wrap the mp4 file in flash.

Anyone have any suggestions on how to improve this work flow?

... using the avisynth script creator...
1. DirectShowSource("you_file.mkv")
2. Encode...

[acidsex]

but isn't avisynth just for the video portion? is there any chance to can provide an example of the script I should using because every time I try to use the avisynth creator inside MeGUI, it crashes and I get this error message: Problem Event Name: APPCRASH

[Sharktooth]

and who told you avisynth is only for video?
load the avs as audio source too...
about the crash, check your system. something is really screwed up.

[acidsex]

Ok heres the steps I went through. Opened MeGUI, went under Avi Synth Creator, selected my MKV file and then MeGUI crashes. Is there a specific file I need to have in my AviSynth Plugins directory?

[Sharktooth]

no. if it crashes then something on your system is messed up (load the mkv in graphedit and post a screenshot).

[acidsex]

could this be a FFDshow problem?

[acidsex]

Ok, went back to XP last night and can import and encode existing MKV files. Is there anyway I can set the video portion of the MKV to pass through to the final muxing in the encoding process or do I still have to demux the MKV to get my video out of it? I would like to keep the entire process inside MeGUI if I can.

No video passthru in megui

You could try avidemux for your task:

Open the .mkv
video=>copy
audio=>aac , setup the options for bitrate & 5.1 channel
format=>.mp4
