So I have a video 3840x2160 resolution and I want to cut out a part of it. So I'd only have the upperleft 2184x1680 pixels. Can that be done in VLC?
Non-Permanent Crop (VLC)
If you want a non-permanent crop, select
Extended Settings in VLC (represented as an icon that looks like several option sliders):
And switch to the
Video Effects tab, then the
Crop sub-tab. Set your preferences accordingly:
If my math isn't off, you will want 1656 for the
Right option and 480 for the
Permanent Crop (ffmpeg)
ffmpeg -i in.mp4 -filter:v "crop=2184:1680:0:0" out.mp4
In this case, 2184 and 1680 represent (respectively) the desired width and height of the output video , while
ffmpeg to start from the upper left corner.
