Make an AC3 192k track with the same number of channels as the source audio as audio track 1 in the output file. Make an AAC 192k stereo track of the source audio as audio track 0 in the output file. I don’t know why this is needed to be honest This is for processing non-ac3 audio (unsure if that is on a track by track basis, if I have a file with AAC and AC3 do both lines get used?).

I’ll take a stab at this and dissect the FAQ strings. At that point I will finally have MCEBuddy set up exactly as I need and I can simply encode for a few months to clear my hard drives of all my TS files. If anyone can give me some insight how to do this it would be much appreciated. Currently the audio in my profile is set to this:īut I would like to try to use this from the original HEVC profile after making the default audio into stereo AACįfmpeg-audio=-acodec ac3 -ab 160k -map 0:aįfmpeg-audioac3=-acodec ac3 -ab 256k -map 0:a

I want a normalized stereo AAC of the default audio, which is usually 5.1 as the new default with all the original audio streams either copied or compressed. Ffmpeg-audio=-map 0:1 -map 0:1 -c:a:0 aac -ab 192k -ac 2 -c:a:1 ac3 -ab 192kįfmpeg-audioac3=-map 0:1 -map 0:1 -c:a:0 aac -ab 384k -ac 2 -c:a:1 copyīut I don’t understand the individual commands.
