MP4 Scrubber

This is my tool for prepping MP4s for using on websites. It removes the audio and any black bars on the video. I set this up because I make a lot of clips in DaVinci Resolve and it's a pain to resize the output in it when I crop in.

Notes

• This is a Rust script that you should be able to run from the command line (I'm not sure if you have to have "nightly" installed anymore or not, but you might). Do a chmod u+x scrub_mp4s.rs on it to make it executable with ./scurb_mp4s.rs

• The process starts in the source_dir. Update it to point to the directory you want to process

• It searches recursively for any .mp4 files in the soruce_dir recursively.

• If it finds an .mp4 and that file is in a directory named raw it checks to see if there's a corresponding .mp4 with the same name in a cropped directory (that's a sibling of raw)

That is, if it finds:

~/some/videos/example/raw/FILENAME.mp4

it looks for

~/some/videos/example/cropped/FILENAME.mp4

• If there's no cropped/FILENAME.mp4 file it makes it

Example

A crop for a video might start out like this:

After running it through the process, this is the clip:

Todo

• Create the cropped directory if it doesn't already exist
