Question about editing 4K footage vs 1080p

2160

Hi, I just opened a couple 4K footages in my Premiere Pro and when I went to the Effect Controls > Position, it says 1920 x 1080.

Is this right? Shouldn't it says 2160?

I opened a 1080 footage to compare, and the 1080 shows up smaller. I understand why... 1080 is a smaller resolution. 4K is 2160... but it still says 1080 in the Effects. Maybe I'm reading it all wrong.

I have a feeling "Position" does not equal "size," but I'm still confused. I'm just making sure there isn't something I need to change in the Settings to edit 4K. I wouldn't want to edit a ton of 4K footage to realize later that Premiere Pro automatically downgrades 4K to 1080 by default unless you change the settings...

Hi Akwon,

Yes, the Position values work differently than you're thinking. The Position value is a coordinate... specifically, the coordinate of the center of the image (actually, this isn't totally, true, it's the Position of the Anchor Point, but that's set to the center of the image by default.

In most Adobe programs the upper left corner pixel's position is 0,0. If you have a 4K sequence, the bottom right corner is 3840,2160. Therefore the center is 1920,1080, since those are half values of the resolution of the sequence. It's a little confusing the first few times you have to deal with it.

But long story short, Position is relative to the resolution of the sequence. In a 1080 sequence, the center is 960, 540 (again, half of 1920 and 1080).

As long as you created your sequence properly (using manual settings or by using New Sequence from Clip or by dragging to an empty timeline panel), your sequence will be 4K, and the Position has nothing to do with it.
