When selecting ProRes 422 HQ as your codec, is anyone able to adjust the quality of the video? I'm assuming that affects the bitrate? I did this just yesterday and ramped it all the way up to 100 on the quality slider, but today it's locked in at 100 and i can't reset it or decrease it.
The Prores codec does not allow you to adjust quality on export; it has a set quality inherent to the version you choose. If you need a smaller file then look at going down to the next lowest Prores setting. In descending order (from highest quality/biggest file to lowest/smaller) is: 4444 XQ, 4444, 422 HQ, 422, LT, Proxy.
