Cutting a short in 4k help

[Steve Marshall]

Hi guys,

I'm about to start cutting a short film, shot in 5kFF Epic. They want it edited and mastered in a 4k timeline. It's at 1.85.

Should I edit in a 4k - 1.85 sequence and resize/reframe as I go. Or should I edit in a 5kFF sequence - if I did a 5k sequence, how would I go from 5k to 4k 1.85?

This is my first professional edit job on PPro and I'm excited by it!

Hi Stephen!

If this were me, I would be editing in a 4k timeline. This is for a few reasons:

- You're not gaining any extra export options by editing in a 5k timeline since final output will be 4k anyway.
- Due to factors such as the OLPF (Optical Low Pass Filter) in the camera and debayering, a 5k image at best only has a measured resolution of 80-85%. Downscaling 5k to 4k will mean that every pixel in your 4k timeline counts as measured resolution.
- Framing 5k footage in a 4k timeline will give you some flexibility if you are forced to reframe or adjust any shots.
- Playback will be easier on the system in a 4k timeline. (For example, with playback set to 1/2 resolution, a 4k sequence is only extracting 2k worth of pixels from the wavelet codec, vs 2.5k in a 5k sequence)

Note: Just max sure you choose "Use Maximum Render Quality" when it comes time to do your final export - this will ensure that Premiere goes and uses the full 5k frame to downscale to 4k. (As opposed to simply "pulling out" 4k worth of pixels)

Thanks for the info Brad! That "note" is very helpful.
