FFMPEG - Who even needs a GUI video editor

So I've been messing around with FFMPEG alot to see how much video editing I can do without using an actual GUI video editor, so far it turns out that the answer is quite a bit.

I go over three main common tasks I've needed to do recently with only FFMPEG:

  • Cutting out a section of a video into its own file

    • The main benefit of this is that this process does not cause a re-encode, which saves an amazing amount of time. When I did the same thing in Davinci Resolve, it took 15ish minutes to render out the clip. FFMPEG took a whole 20 seconds.
  • Cleaning up a video clip by removing "frozen frames", using the FFMPEG filter called mpdecimate (Frozen frames are sections of a video where there appears to be nothing happening, hence it looks frozen)

    • This is really useful for making time lapses of processes, as you remove all the dead frames and you get only 100% action going on.
  • Taking the decimated video and creating a time lapse of any duration in seconds by calculating the value needed to adjust the presentation timestamps to get the desired duration.

    • This one has been really handy for making time lapses of my wife's design work. I've used it so far to make versions for Instagram and Tiktok.
