How to watermark a video?

Question

linux

The whole day already in yandex and google I did not give any results, tell me how to watermark videos in Gnom 3?
OpenShot did the job, but the video comes with a jamb and a watermark on 1:4 of the screen, this is when the size of the logo itself is 100px x 50px.

In general, OpenShot will do just fine. You just need to position the image correctly.
