Introduction
If you've come this far, all of the grunt work is out of the way - now you just need to put together the separate video and audio tracks into one final package and show it to the world (or at least the TASVideos community).
Muxing
This step differs slightly depending on if you are using the DeDup plugin for AVISynth or not.
Assuming your video track is
video.mp4 and your audio track is audio.ogg, you will need to use one of the following two command lines to mux together your audio and video.
If you are encoding for a console intended to be displayed on a TV, you will need to specify a 4:3 aspect ratio thus:
mkvmerge --aspect-ratio 1:4/3 video.mp4 audio.ogg -o encode.mkv
If you are encoding for a handheld console, this is not necessary:
mkvmerge video.mp4 audio.ogg -o encode.mkv
If your encode is meant to be uploaded to streaming video site with time limit, add
--split duration:hh:mm:ss.sss, where actual time limit is set, to your command.
If all goes well, after running the command and a brief delay you will have your final
encode.mkv. Congratulations!
You will need to instruct
mkvmerge to use the times.txt file output from DeDup; this is done by adding --timecodes 1:times.txt to the command line before the video track as follows:
(for TV consoles)
mkvmerge --aspect-ratio 1:4/3 --timecodes 1:times.txt video.mp4 audio.ogg -o encode.mkv
(for handhelds)
mkvmerge --timecodes 1:times.txt video.mp4 audio.ogg -o encode.mkv
Note: OGG Vorbis audio is effectively incompatible with the MP4 container; you should be using AAC audio if you are muxing to MP4.
Note: If x264 output was to raw .264 file, add
-fps 60 (or whatever the fps is). Otherwise the final .mp4 will play at wrong speed.
Use the following command line to mux the two into an MP4:
MP4Box -add video.mp4 -add audio.mp4 -new encode.mp4
If all goes well, after running the command and a brief delay you will have your final
encode.mp4. Congratulations!
You will need a copy of Aktan's NHMLTransform program; grab it from http://forum.doom9.org/showthread.php?t=150890
Run
MP4Box video.mp4 -nhml 1 MP4Box audio.mp4 -nhml 1 NHMLTransform.bat -i video_track1.nhml -t times.txt -o video2.nhml -ia audio_track1.nhml -oa audio2.nhml MP4Box -add video2.nhml -add audio2.nhml -new encode.mp4
You will need a copy of Ilari's NHMLFixup program; grab it from Forum/Posts/246798 (the Lua executable it requires can be obtained from http://luabinaries.sourceforge.net/ (windows), distribution package repositories (Linux) or compiled from source (Unix) ).
Assume you have saved the audio track as
audio.mp4, video track as video.mp4, timecode file as times.txt, the NHMLFixup script as NHMLFixup.lua[1], and your Lua binary is lua[2], Then run (assuming non-handheld game):
MP4Box -nhml 1 video.mp4 MP4Box -nhml 1 audio.mp4 lua NHMLFixup.lua video_track1.nhml audio_track1.nhml times.txt tvaspect MP4Box -add video_track1.nhml -add audio_track1.nhml -new encode.mp4
If this is handheld (GBx, GG, DS, etc..) game, replace the NHMLFixup command with
lua NHMLFixup.lua video_track1.nhml audio_track1.nhml timecodes.txt
That is, leave out the
tvaspect option (since aspect ratio correction is not wanted in that case).
This saves the resulting encode as
encode.mp4.
Note: The audio track ID may not be 1! If you convert raw .aac file to .mp4 using some versions of MP4Box, the resulting track ID will be 101, not 1!
Uploading
Prior to uploading, you should rename your encode according to the Publisher Guidelines. This usually takes the form of
<gamename>-tas<version>-<branch>-<author>.{mkv|mp4} with <version> or <branch> being omitted as necessary.
Although all published encodes are mirrored on archive.org, we prefer that you only upload a movie there if you know that it is going to be the encode that is published (i.e. when the movie has been accepted and the publisher has informed you that your encode will be published). Many of our encoders use MediaFire for temporary hosting of encodes when the above conditions are not met, though you can use any other file hosting service at your discretion.
Once your encode has been uploaded, post a link in the discussion thread to your encode. You're done! Now everyone can enjoy the end result of your hard work.
