Batch script files for FFMPEG (Microsoft Windows and DOS, OS/2 )

My collection of scripts :)
For converting (audio, video, ...) files using FFMPEG :)

ToDo and Future

add https://github.com/nagadomi/waifu2x
add boomerang GIFs https://superuser.com/questions/1608327/ffmpeg-boomerang-effect-to-gif
add image2pipe and video pipe2image https://stackoverflow.com/questions/46397240/ffmpeg-image2pipe-producing-broken-video
add slow-down or speed-up gifs: http://blog.floriancargoet.com/slow-down-or-speed-up-a-gif-with-imagemagick/

How to use:

1. Edit the batch script to your liking. For example, where to trim the video.
2. Just drag a video or audio file onto the batch file. :)

Logic

All files have MAIN Code - where you can find main command(s) for ffmpeg.exe
This main command has comment mark:
REM //////////////////// MAIN \\\\\\\\\\\\\\\\\\\\\\\\\
Than main code-command(s) for ffmpeg.exe (Video-ToMP4_FPS-24-25-30-60.bat for example):

 ffmpeg -i %%x -r 30 -vcodec libx264 -acodec copy -map_metadata 0 -map 0 -threads 1 "%%~nx_output_FPS30.mp4"

Scripts

Audio-AudioGain.bat

Gain (Increase) the sound volume of a file on 50% MAIN Code:

ffmpeg -i %%x -filter:a "volume=1.5" -ar 44100 -ac 2 -q:a 0 -map_metadata 0 -id3v2_version 3 "%%~nx_output_GAIN%%~xx"

Audio-ToMP3_RemoveSideData.bat

useful for: remove ReplayGain

This bat file doesn't reconvert the original mp3 - because it is the fastest way.
In the same way, it doesn't change the original quality.
But on the other hand, it removes all sidedata from metadata (but save all metadata)
Read this about sidedata and lameinfo (xing) "The ‘lame’ (or xing) header is not officially part of the mp3 specification"

Video-ToMP4_FPS-24-25-30-60.bat (How to change frame rate of video, fps of video by ffmpeg.exe?)

Can change frame rate or FPS of video and recode it to container .mp4 & video codec x264.
By default it is -r 30 - 30 FPS. Choose what you want in MAIN Code:

REM ffmpeg -i %%x -r 24 -vcodec libx264 -acodec copy -map_metadata 0 -map 0 -threads 1 "%%~nx_output_FPS24.mp4"
REM ffmpeg -r "25" -i %%x -vcodec libx264 -acodec copy -map_metadata 0 -map 0 -threads 1 "%%~nx_output_FPS25.mp4"
ffmpeg -i %%x -r 30 -vcodec libx264 -acodec copy -map_metadata 0 -map 0 -threads 1 "%%~nx_output_FPS30.mp4"
REM ffmpeg -r "60" -i %%x -vcodec copy -acodec copy -map_metadata 0 -map 0 -threads 1 "%%~nx_output_FPS60.mp4"
