Useful bash/python scripts for manipulating media files (videos, images) with ffmpeg, exiftool or yt-dlp.

Usage of most scripts:

1. Place the script in a folder where media files (mp4, mp3...) are located.
2. chmod x script.sh;
3. ./script.sh
4. Some scripts accept arguments in the format: ./script.sh <arg1> <arg2>

This tool removes the noise from low-light images with image stacking. You need multiple images: you need an image sequence shot from a tripod, from the same position. The program merges the images, filtering out the noise.

Usage:

python3 image-noise-remover.py  input_folder_with_images/  output.jpg

It converts the video files (mp4, m4v, mkv, avi, mpg) found in the folder (and subfolders) to .mp4 format with the specified settings using ffmpeg.

It sets the configurations through a series of questions. It's almost like an ffmpeg GUI, but in the command line.

Choose a resolution:
1) 426x240  2) 640x360   3) 854x480
4) 1280x720 5) 1920x1080 6) 2560x1440 7) 3840x2160
#? 2

Choose a Compression Rate Factor CRF (recommended: 26)
(bigger number = more compression, smaller number = quality):
1) 30  2) 28  3) 26
4) 24  5) 22  6) 20
#? 3

Choose a FPS Frames Per Second value (recommended: 30):
 1) 60   2) 30   3) 25   4) 24   5) 20
 6) 15   7) 10   8) 5    9) 4   10) 2   11) 1
