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.

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.
