How the numbers work
Crop width and height are the size of the piece you keep. The offsets say where that piece starts, measured in pixels from the top left corner of the original. Leave "centre the crop" ticked and the offsets are worked out for you, which is what you want most of the time.
Some useful crops from a 1920 × 1080 source:
- Square: 1080 × 1080, centred.
- Vertical 9:16: 608 × 1080, centred.
- Remove a letterbox bar: keep the width at 1920, set the height to the real picture height, and set the top offset to the bar thickness.
Run the media info tool first if you are not sure of the source resolution.
Common questions
Can I drag a box over the video instead of typing numbers?
Not yet. Grab a frame with the frame tool, open it in any image viewer to read off the pixel coordinates, then type them here.
Does cropping re-encode the video?
Yes. Cropping changes every frame, so it cannot be done by copying the stream.
