  1. For whatever reason, EVERY example script I have found has failed horribly. JS, BAT, PY every single one of them. I don't even have the first clue how people are getting the damned program to save JS files.... Why can't anyone make a tutorial for JS and PY illiterates? I don't even have the first clue on what I am doing. I've been trying everything I can find on the net for the last 4 days. The only reliable method is doing each and every file individually which means I can do nothing besides sit in front of the computer waiting for each file to complete. I am at my wits end here. I've done the --help and all I can do is look at the resulting info and say "yup, those are certainly commands... HTF do I use them?"

    All I want to do is make a batch file so that it will take the video files within a certain folder and just normalize the audio. That's all I want.... Just audio normalization.

    Any help is appreciated. Just please don't link me to the tutorial or wiki..... I've tried those many MANY times and no success.

  2. Are all the files roughly the same specs? ie. same container, 1 audio track, same compression ?

    If avidemux isn't working out, you can possibly do a batch with ffmpeg / sox

  3. Ya, checked them all with Gspot. Same specs for all of them. I just can't get any command line or batch processing that will do a "one and done" setup. I've seen other people say they've done it but not giving the code they used.

  6. This is example of a batch file. It pipes to sox for the normalization and back to ffmpeg. It's set to normalize to -3dB currently. Change the value to what you want.

    Open notepad in directory of files to be converted. Copy & paste the following, save. Rename the .txt to .bat extension. Double click the .bat file

    All MP4's will be processed in that directory. The video will be stream copied, but the audio will be normalized and re-encoded with libvoaacenc with 192kbps. Change the bitrate if you want. The new files will be in the same directory with the same name, just the "new" added on to the filename, but you can specify an output path, and you can change the filename if you want

    You need ffmpeg and sox. If they are not in the search path (either the same directory or setup as an environment variable) you can change the script to reflect the paths of the .exe files

    for %%a in ("*.mp4") do ffmpeg -i "%%a" -f sox - | sox -t sox - -c 2 -r 48000 -b 16 --norm=-3 -t wav - | ffmpeg -i - -i "%%a" -map 0:0 -map 1:0 -c:v copy -c:a libvo_aacenc -b:a 192k ""

  7. Received the following two errors:
    pipe:: Invalid data found when processing input
    Could not write header for output file #0 (incorrect codec parameters ?): Error number -22 occurred

  10. Cheers

    For the original avidemux issue, did you try asking in the avidemux forum ?
