how to export 4k from Redrushes

[Chris Pickle]

How do I get a 4k file from Redrushes? So far I've only been able to get 2048 x 1152

My plan is to open the 4k file in AE and then crop / reframe, then export a 1080.

Also, what 4k file format is best to do the above?

Thanks for any help!

I've made some headway.

I exported 4k tiff sequences from Clipfinder and used the RSX ins & Outs. The tiffs matched perfectly in size to the single TIFFs exported from RedRushes. In CF, I used full res debayer and uncompressed 4:2:2 8bit

I also exported a QT this way. I left the scale width / height blank and the QT file came out in 4k.

Question. Is this a legit 4k file? or is it just being scaled up from 2k, which I understand is the limit on Redrushes?

If CF is using that "engine" then maybe it's not a legit 4k QT file?

Thoughts?
Thanks,
Chris
