Another question – in your image you show quicktime, h.264, 1280×720 (linked). When I set it to quicktime, h.264, and change the size to 1280×720 (while linked) it won’t accept it and changes from 1280 to 1080 for example. I can only get your pictured settings by unlinking the height & width.
Thanks for any info on this plus my last question about the bitrate.
