Set split point for "Crop to Portrait" feature for clips
The "Crop to Portrait" feature for clips when using the "split" mode splits to something like a 16:9 and a ~2:3 for your two view boxes, putting the split point with the username about 2/3 up on the screen.
For creators where these box sizes aren't optimal, we should be able to slide where the split/username is and get different shapes for the top/bottom boxes.
For example, I play a lot of 4:3 games, and my camera is relatively square, so planting the username split right in the middle and having two squares to work with would make my crops look much much better.
This picture is an example of why the current setup works very poorly for me: https://cdn.discordapp.com/attachments/628786693117313035/1214671546833047592/image.png?ex=65f9f608&is=65e78108&hm=eef7e100aeca5acc43858e4b7dfd872ed2bda9041555fd15dda0b0442108d097&
