I wrote a tiny little shell script to help upload videos I've clipped. I figured I would share it because it's something that really makes my life easier, and I figured others would appreciate it.
What the ffmpeg command does is essentially put the video down to 720p if it's higher, and reduces the quality it's encoded at. Doing this most of the time cuts the size of the video in half. Even more importantly it cuts down the upload time by much more than half. Like it's a night and day difference. The speed improvement is more noticeable than I would have ever guessed.
The way the script is designed to work. Is you put all the clips you want to shrink in a directory. cd into it. then run the script. It loops over all the files, runs the ffmpeg command. Which outputs the processed file with an "s-" in front of the original name. This is to avoid file name collisions. I figured it's best to keep the input file around in case something goes wrong, or if people just want to have it for whatever reason.
Heres the script itself. I thought I might as well throw it in the linux threads since it's a shell script afterall. But I will probably throw it up somewhere where not autists might see it and benifit from it.
Bash:
#!/bin/sh
for f in *.mp4; do
ffmpeg -i "$f" -vf scale=-1:720 -c:v libx264 -crf 28 s-"$f"
done
It's so simple it might as well be a one liner. It's a for loop in sh so obviously it's more than one line, but it's about as simple as a loop can be.
Oh, and obviously someone could change the file extention I have there to something else. Or remove the file extension all together, and just leave the * to work on any file in the cwd.
