Uploading video project from Final Cut Pro to YouTube

Let me start over. I have a video project in Final Cut Pro that I used video from my iPhone 12 Pro Max to create project with, and I'd like to upload it to YouTube. When I use the "YouTube and Facebook" upload option it gives me a warning message saying "Using an 8-bit codec with HDR content may effect video quality", so then you had me make a "Master File" in 422 and save it to my computers hard drive. Is that the file I should load to YouTube then? And if I have 35 minute projects to upload will that work on YouTube without being too large to upload? Or take too much time? I'm just trying to learn the best method to do all of this.

ProRes 422 will give you the best quality output. It's 10-bit and will export HDR. The files are very large, so to upload you'll need a very fast connection without too much variance. I don't know what YouTube will do to it.


The best way in my view is to use Compressor as it gives you a lot more control on the data rate you export. There is no one button, one size fits all answer for outputting a video file. It depends a great deal on what the content is. A talking head can take a much lower data rate than that used in FCP, which makes pretty large files. A video with a lot of action, very short shots, plenty of transitions and titles will need a much higher data rate, higher even than FCP uses. Compressor gives you these options.
