Step 6: Audio Encoding Options

Now it's time to set up the audio encoding options. If you've followed this guide for DVD conversion, then the demuxed audio track we selected in the D2V Creator should already be loaded in (if not, load in the .ac3 file that was created). If you are not converting from a DVD source, then you can either load in a separate audio file or if you edited the AviSynth script (set "audio=true"), then load in the AVS file into the "Audio Input" section (meaning both video and audio inputs are the same AVS file). Repeat if you want a second audio track by clicking on the "2" select option.

MeGUI: Audio


Now we select an audio codec to use. I prefer AAC audio, especially with H.264 as video - AAC is to MP3 what H.264 is to DivX/XviD, better compression + better quality. So which audio codec should you use? I prefer ND AAC (Nero Digital), so select it if you agree with me. We can now choose an audio profile from one of the "NDAAC" options. "NDAAC-HE-64Kbps" is the one I like, as it will give you roughly the same quality as a 128 Kbps MP3 file. You can select one of the "HEPS" (HEv2) profiles if you really want a small file size. The "LC" options offer better compatibility (eg. with iPod/iTunes), but at the cost of file size (still smaller than MP3s though).

For more information on AAC audio options, please refer to this MeWiki page or this Wikipedia entry.

Excellent guide! The only problem I have with this approach is that you can't control the output resolution very efficiently (meGUI reports 16:9, but outputs the video in 4:3 anyway, and if manually resized the output is skewed anyway) and the output video is extremely washed out compared to the original. I played back the resulting mp4-file in Quicktime, VLC and other players and it's the same on all, blacks are grey. The entire picture has a LOT of brightness.

Thanks, I've been trying to learn how to use this tool. There is a doubt in using autoencode: I'm not sure the profile I chose is used or not. for example, in the main input interface, I chose MKV as container and then the video profile. But when I press autoencode, the window pops up did not show any chosen profile while the container is MP4 as default... It feels the the settings in main input interface are ignored?

Astro_Toy: Rest assured that the profile settings are being used. However, you do need to separately select the container (MKV, MP4) since this setting is not part of the profile.

I keep getting "error" for audio when I start the encoding. Any ideas? I tried .mkv & .mp4 & I tried both the 5.1 audio track & the 2.0 track from my DVD.

Check your application routes in settings, Had that same problem encoding with NeroAAC and it was because I didn't have right route to the codec. Hope this helps. :-)

I'm getting this error:"C:\Program Files\megui\tools\x264\x264.exe: unknown option -- nal-hrd" when I encode using the SA Blu Ray profile. I made up my own blu ray profile without the --nal-hrd option. It is running now but I have to wait another 9 hours for it to finish (I have a crappy 1.8 GHz Athlon PC) and see if the result is any good. In the meantime, can you point me to any fix to this error?

Sibenik: That profile works for me. Are you using the latest version of x264 as updated through the MeGUI updater (as opposed to downloading the latest x264.exe from the official site)? Try that if you are still getting this error.

ok i keep getting an error when trying to use the avisynth creator it is a " Unable to render the file. You probably don't have the correct filters installed." all of the options are greyed out other than the Video input the avisynth which is set at "*scratchpad*" with the config button available and also the video output is available. I've followed this tutorial but it doesn't address this issue but i might have missed something. Any thoughts guys?

Roguecat: Sounds like you don't have the right filters installed. Make sure you are able to playback the file in Media Player Classic, and it is highly recommended that you use ffdshow, as it works very well with Avisynth
