After clicking around for a few hours…
1. The ProRes definitely seems to work the best. However, every time I Add my file to Encoder, the Output automatically puts horizontal black bars around the clip. I ended up just changing the aspect ratio to 1440×810. Plays perfectly smooth. Why is that?
1.5. I also tried the Apple Intermediate Codec at 1920×1080 and, I believe, changed the Pixels to HD anamorphic wide. That worked very well. (But then again I assume this will not upload to Vimeo…
2. The H.246 for Vimeo – basically I would like to keep an aspect ratio of at least 1280×720, the H.246 codec, and keep it under 500mb. I tried running that large reference file through Compressor for the heck of it and it worked very well – expect that the colors were washed out and there doesn’t seem to be a way to fix that.
Also, if there are good explanations of Pixels such as square verses everything else, that would be helpful in figuring this out.
Thank you so much! I do appreciate it.
