1. Re: Youtube and 4K/5K clips
Colin Brougham Sep 21, 2011 6:42 PM (in response to ectobuilder50)Maximum resolution on YouTube at present is 1920x1080. I'm sure you could upload a 4K file, but it would be down-rezzed.
Premiere Pro doesn't ship with an H.264 1080p preset for YouTube, but you could use the H.264 720p YouTube preset as a starting point and then increase the dimensions as well as the bit rate a tad. You'll have to do a little experimentation to find the bit rate that preserves the most quality after YouTube does its dance on your upload. YouTube no longer passes through anything--everything uploaded is reencoded--but there's a practical limit to which you can increase the bit rate before you start receiving diminishing returns for longer uploads.
My YT 1080p preset is something like Average Bit Rate 8Mbps/Maximum Bit Rate 10Mbps, but typically my videos don't go much over 5Mbps due to the content. Every video is different.

ectobuilder50 Sep 21, 2011 7:46 PM (in response to Colin Brougham)So how do people get 4K files to YouTube? They upload the RAW R3D file?

Colin Brougham Sep 21, 2011 7:48 PM (in response to ectobuilder50)I'm saying that most people don't--and I'm not sure YT would accept any 4K file, much less an R3D file. You'd be uploading forever...
I'm confused: are you trying to post a finished video on YT or distribute raw footage?

ectobuilder50 Sep 21, 2011 8:19 PM (in response to Colin Brougham)Are you sure Youtube doesn't support 4K?

Colin Brougham Sep 21, 2011 8:39 PM (in response to ectobuilder50)OK. There you have it. Frankly, I don't see the point--it takes forever to buffer and I don't know about you, but I don't have a 4K monitor.
Why not try to upload an R3D file? YT is going to convert whatever you upload, anyway, so if that doesn't work you can always try an MP4.
I downloaded one of those. Here are the guts:
