I want to use ffmpeg-normalize to normalize the volume of 100 mp4 video files. Is there a way for the program to run through all of them to determine a proper level - or must I give it one file as input Can it convert an entire folder without listing 100 filenames I tried using ffmpeg-normalize *.mp4 (while the command line prompt was in the directory of the videos), but it gave error \"file *.mp4 does not exist\"I am using ffmpeg on a windows system, but I will be playing the files through a KODI player on a nVidia Shield. I just want to be able to play through the videos without have large swings in volume.
I've seen a Windows solution like what I've produced here, created by someone else many years ago - but I don't know what it was called, nor where to get it anymore. I also think it was only for AVI files. I've resorted to writing my own from scratch to handle MP4's. I'd like to share this with anyone and everyone who are interested as this site has helped me a lot to get me to this point.
I've written a DOS batch script in my Windows 10 that can take multiple *mp4 files (and yes - with spaces in the name) and normalize the volume using mp3gain. (I tried MP4GAIN, but the trial period ended in like 1 hour). This one will process much quicker than MP4GAIN, I found out. I do this because I can specifically control ffmpeg and mp3gain every step of the way and do things that mp4gain or ffmpeg-normalize might not be able to.
By all means, it's not fool-proof, nor is it optimized. Rather it can be a springboard for someone to tune/tweak for their own purposes. I extract the audio as mp3 VBR and let mp3gain do its magic on it and then put it back. I find I can process 5 concurrent normalizations, but it's subject to the available hard disk space if you want to try more at once.
Place the original mp4's into your C:\\Vids\\original folder and run normalize.bat. I do it from the cmd.exe DOS prompt, but you can double-click the batch file in Windows Explorer too. It will search the original folder for mp4's and create individual batch files in C:\\Vids\\working. You can kick off one, two or four of these batch files in C:\\Vids\\working at once.
Each original mp4 will be unpacked into a mp4 with no audio, and an mp3 VBR with no video.The video and audio extractions are done at the same time, thinking this will likely produce two files that can be merged back together later without the video or audio being shorter than the other. The video and audio extracts go into C:\\Vids\\working.
I don't have a check for ffprobe to see if the embedded audio is already an mp3, and I found that not all aac audio can be normalized by aacgain.exe. Hence I force everything to come out as mp3 VBR at the highest quality. If the original audio of sufficient quality, I don't mind doing this.
If people can extend this script further to make it aware of the various audio types and do an audio copy if it is already mp3, it would be helpful. Or recognize that the AAC audio needs to be converted to mp3 or left alone as AAC.
Played with this in the past but my knowledge of code was meh,I thought lets have another go now I understand the settings and perculiarities of hosting and so on.Woot, I got what I wanted and I think its what you want.If it is, tick the love heart and solution please.
