ffmpeg is great!

If you want to compress a video without visible loss in the quality, here's the command:

ffmpeg -i input.mp4 -vcodec libx264 -crf 28 output.mp4

And if you want to speed the video up by, say, 1.33x, you can just run the below command:

ffmpeg -i input.mp4 -filter:v "setpts=0.75*PTS" -filter:a "atempo=1.33333" -r 60 output.mp4

And you can also combine both above commands into one, just run the below command and your video will be compressed as well as become 1.33x faster in seconds:

ffmpeg -i input.mov -vcodec libx264 -crf 28 -filter:v "setpts=0.75*PTS" -filter:a "atempo=1.33333" -r 60 output.mp4

Here's a command that normalizes the audio of videos that I record using Screen Studio + Krisp.

ffmpeg -i input.mp4 -c:v copy -c:a aac -af "loudnorm=I=-17:TP=-1.5:LRA=11" output.mp4

Make sure to cd into the folder where your video file is, and replace input.mp4 with the actual video filename you have.
