Usage¶

Bunch of examples.

No cutting, just a filter¶

You just want to add a blur to a clip:

ffmpeg-cut "recording 1.mp4" recording-blured.mp4 -f 50:760:455:280:boxblur=5:4

That will actually chain 2 filters:

A crop filter with options 50:760:455:280. There will always be a crop filter injected, so if you want the whole area you’ll have to specify it, eg: 1920:1080:0:0.
Your filter (boxblur) with radius 5 and power 4.

Few cuts without files¶

ffmpeg-cut "recording 1.mp4" recording-cut.mp4 00:00.000-01:23.456 02:34.567-02:56.789

Simple text files¶

If you have a lot of cuts with more than 1 input files create a file named my-compilation.txt that contains:

recording 1.mp4
00:00.000-01:23.456
02:34.567-02:56.789
recording 2.mp4
00:00.000-01:23.456
02:34.567-02:56.789

Then run:

ffmpeg-cut --text my-compilation.txt my-compilation.mp4

Files without common fps¶

A common issue with nvidia overlay 60fps recordings is that input files do not have identical fps (eg: recording 1.mp4 has 59.55, recording 2.mp4 has 59.66 - ). Add this to your command line:

--fps=60

Uploading clips to chat software¶

If you’re not uploading to youtube you might want to use very high compression to fit upload limits. Add something like this:

--encoder=libx265 --quality=32

Cropping and overlaying¶

Should you want to create vertical videos from desktop captures you can overlay two sections from the input recording:
