I've been using TMPGENC to encode avi's to mp2 and m2v and the mp2 file has no sound, ive tried to re encode the sound numerous times with tmpgenc but it keeps coming out blank. I opened the avi with virtual dub and it said its a VBR audio or something, anyway, can someone tell me the easiest method nad what tools to use to rip the audio from this avi to a mp2 file that is 256kbs
Open the avi in virtualdub. Click file, save .wav Open the video in tmpgenc, select the .wav file you just saved as the audio source. Encode.
i only want the audio to be 256 though, how do i choose the encoding for wav? I need to conserve space
Extact the sound as uncompressed WAV with VirtualDub. If the AVI has AC3 sound you'll have to demux directly (and to use in DVD authoring or converting it to MP2 later [to gain only a few megabytes of free room for the video, in your DVD]). Compress the WAV to MP2 (224 kbps) with HeadAC3he of FFMPEG GUI. The bitrate can be selected more easiy in FFMPEG, though 224 kbps is already optimal (384 kbps is optimal for AC3 5+1).
Tmpgenc will encode the audio to mp2 to go with the video, but it needs to be extracted to uncompressed .wav first, to remove the vbr. Ffmpeggui would convert that wav to ac3 easily (as adalco has mentioned) then you would author the encoded video (with no audio) with the AC3 in your authoring app.
