to embedd something into a video you have to reencode the video. for this you have to extract frame by frame, add your watermark to each frame and reencode each frame.
i would use
ffmpegfor this task.qt and it’s multimedia framework might help to decode a video, i am not aware of the encoding part. so, to answer your question: no.
