Frequently asked questions
What is the difference between cropping and resizing?
Cropping removes parts of the frame and keeps the rest at full detail. Resizing scales the whole picture to a new size. Use Resize Video for the latter.
Why are width and height always even?
Video encoders require even dimensions, so the crop box snaps to even numbers.
What if Remove black bars finds nothing?
Then the picture already fills the frame. You can still draw the box by hand.
Does cropping lower quality?
The picture has to be re-encoded, which is lossy but barely visible at normal settings. Pixels inside the crop are not scaled.
Is the video uploaded?
No. Cropping runs in your browser with hardware encoding where available. Files your browser cannot decode use ffmpeg, a one-time download of about 32 MB that is slower.
