Importing 4K 4096 × 2160 (from a 1DC) to FCP as ProRes 422 1080x1920p?

[Alyssa Ryvers]

If the editor I’m working with decides we should cut with the 4K files in a 1080p timeline, do you think I will be able to run the session using proxy media, or will my system still not be able to keep up?

Again, I’m working on FCPX v. 10.0.9 on a MacBook Pro 2.53 GHz Intel Core 2 Duo w/ 8G RAM on OS 10.6.8 using a FW800 drive (7200RPM)

Best,

Alyssa

It’s going to be tight, Alyssa. Is the editor using your machine or will they have their own?

The Proxies will certainly work a lot better as they will be half size, but that’s still a 2k file.

Thanks, Jeremy!

The editor has his own system.

I gave it a try on my computer with one clip — seems to play back fine…I’d say it may work…

Thanks so much to all of you for sharing your expertise with me 🙂

Best regards,

Alyssa

If you need to convert a bunch of 4K video files to ProRes422 1080p, here is a 4K video to ProRes Converter for you. It is able to batch process 4K videos like the most hot XACC/XAVC S files to Apple ProRes. You can either downsize 4K to 1080p or keep original 4K ultra HD resolution.

NO!!!

by maintaining the full 4096 width when scaling to 1080, you will reduce the overall quality of the compressed content by as much as 50% (especially when the using the default compression output settings from either FCP or Premiere. I recommend that you crop the file to 3840×2160 prior to the downcoversion step so that the scale was handled seperately from the the compression to 1080.
