RemoveVideoBG cuts the background out of a video automatically, so you do not need a green screen or manual masking. You upload an MP4, MOV or WebM clip and download the result.
Exports include a transparent WebM with a full alpha channel, or ProRes and MP4 with a new background. The site says it keeps fine detail like hair, and it supports high resolution clips of moderate length. It is free to try with no watermark.
