Question
The only simple solutions I've seen either (1) don't do batch processing e.g. Screenflow or (2) do batch processing but an hour of video takes an hour of processing. I want to be able to upload 20 hours of video and not have it take a full day. I'm not a video person, not a techie, just want a simple solution to handle this one feature. Thank you :)
Answer
My recommandation is: import your video files in Final Cut Pro, insert a PNG with your watermark, place it and size it in the frame, stretch the PNG duration to match your video file, output QuickTime file in the format of your choice.
