Repo 4k footage and export to 2k
hey everyone,
sorry if this sound like it’s been touched on before but ive searched extensively and havent found an answer to my specific question.i have a film that was shot and colored in 4k however we will be mastering in 2k. also the director wants to do some blowups and repos. i wanted to online in the highest resolution possible but the director insists that im losing image quality by blowing up a 4k image and downresing to 2k during export- i figured that premiere would resample the image from the source footage during export and that the quality would be effectively the same. am i wrong?
thanks

When zooming in on a image in a matching sequence you will loose quality. Premiere does not upscale
If you drop the 4K in a 1920×1080 sequence you can zoom in on the 4K up to 50% without loosing quality as 4K is twice the size of 2K.———————————————–

right but my question is: what’s the difference between putting 4k ftg into a 1080p timeline and rendering at 1080p VS leaving 4k ftg in a 4k timeline and rendering at 1080p? aren’t you downsampling a 4k image to a 1080p one either way?

I you do your repositions and scaling of the 4K footage in a 4K sequence, then you are blowing up your footage beyond it’s limits, and losing image quality. If, however, you put that 4K footage into a 1080 timeline (or 2K timeline) and THEN do your repositions, you don’t lose any quality. Because putting 4K into a 1080 timeline means, as Ann said, that your footage is only 50% the size it normally is…so if you push in, then you might get to 60%, or 70%. Unlike doing the same in a 4K sequence where you blow up the image now to 125% or so…for example.
It’s better to put the timeline clips into a 1080 sequence, then do the resize and repo.
