I have a lot of old clips with volume all over the board and I want to set them all to Peak Normalization of 0dB on convert. I know ffmpeg-normalize can do it but I would prefer not to have to create another copy of the file if that's possible and do it as they are converting. Thanks!
Hi, you could use the loudnorm audio filter, though I can't help much with the filter specifics, something like:
-c:v copy -c:a aac -b:a 128K -filter:a loudnorm
