How well does this work with 4k?

I have a 4300x2600 (or so) video and I'm cutting it down to the usuable parts with Adobe Premiere, but that's taking more than 10 hours to encode at native resolution. That has me worried that I am in for a hard time in the faceswap phase. Should I downscale it to 1080 or so?

You will definitely have an easier life downscaling to 1080p.

One thing to be aware of: make sure that your HD source is not HDR footage. AI struggles with this.

Thank you! I did it anyway on the assumption, but I appreciate the confirmation!
