I'm trying to upload a video to YouTube from Final Cut Pro X. When I use the Share > YouTube option, the upload happens pretty well.

There are bugs though: it asks me for my password 10+ times, it uses defaults that are different than the ones on YouTube.com, etc.

Furthermore, I also want to have a copy of the exact exported file so I can upload on other sites too.

Because of all of these, I'd prefer to export my video into the file system, and go to YouTube.com and manually upload it there (rather than having Final Cut Pro X upload it for me automatically).

However, when I go to export the video, I'm not sure what is the best format to use when uploading to YouTube:

Presumably Final Cut Pro X already figured it out and is using the best format settings when you choose to upload to YouTube. However, it doesn't show you which settings it uses:

What settings is it using to export a video when I choose the YouTube option?

I tried doing my own investigation by uploading to YouTube and then downloading the vide, but the problem is that the downloaded video from YouTube is significantly smaller (and in a different format) than the ones you upload.

For example, when I chose to export using the following Video codecs, I got these file sizes, and these download sizes:

• Source (Apple ProRes 422): Exported a .mov at 4GB. When downloaded via YouTube, it was an mp4 at 18MB.
• H.264: Exported a .mov at 400MB. When downloaded via YouTube, it was an mp4 at 18MB.

Interestingly enough, when uploading to YouTube on the website, it said that upload speeds would be improved if I chose a format that was streamable (implying that H.264 was not streamable).

Video / Audio quality:
Your videos will process faster if you encode into a streamable file format. For more information, visit our Help Center.

... which shows these ideal settings:

However, even when I try to upload an H.264 encoded .mov file, it shows me this warning. Is it because it's not in .mp4 format? And if so, how do I export as .mp4 format?

Source () = 4GB (download mp4 @18MB) H.264 = 400MB (download mp4 @18MB)

Still said to upload in a format that is streamable
