10.4.9 Proxy H264 & ProRes Bitrates?

Hi There, I'm busily reencoding 64TB of footage to 1080p H264 proxies right now (joy) so our editors can work remotely and deliver drafts in proxy.

Just wondering anyone has created a list of data rates for all the variants of Proxy H264 and ProRes in the 10.4.9 update - we're using 1080p H264 now ( which QT player tells me is ~15MB Mbits / sec)?

Thanks

I don't have that info at hand, but I suggest before doing 64TB you pick a smaller set of files and use those for testing. At various resolutions, evaluate visual quality, transcode time, encoded bit rate, file size, etc. Verify relilnk works at the final encoding chosen, esp. if on a different volume name and using different file paths.

Don't do 64TB only to find there is some issue with audio, file path or encoding format that prevents relink.

Never found a way to determine data rates in FCP unless I export a file and peek inside. That 15 mbps is about right. I use Compressor to reencode files. That way I can get the max data rate (19,531) for a 264 file where punting the same from FC only gets you 15,000. Compressor allows you to dial in whatever rate you please.

So far I've done some texts and noticed that the 'Upto 1080p' H264 comes out as about the same size as the older pre 10.4.9 proxies of 540p. (but now at 1080p of course).

I'm going to try some more tests now, namely 'Upto 1080p' Prores Proxies - and see if they come out the same. They would be easier to edit if the visual quality holds up.

I could use compressor but I want to make this workflow as simple as possible for our external remote editors, so staying inside FCPX if possible.
