Question

Re-Sizing 8K Footage - Which Timeline Frame Size, and...

...does it adjust automatically if I change settings "after the fact"? Based on what I found on this forum, it looks like it you can change the frame size at the end of an edit, but what I'm not clear on is how this will affect any reframing/re-sizing I do.

 

I'm thinking I should probably edit in a 4K sequence, but getting a sense that maybe it doesn't matter, 'till final delivery—even if I've reframed/re-sized some shots?

 

Thanks in advance!

Depends on the process used. If you have the preferences option for "scale to frame size" selected for sizing, THAT option scales the clip to the frame size ... period. And all further scaling work is done from that frame size, not the original clip. NOT good if you scale back up.

 

Set to frame size as the preferences option merely fits the clip into the framesize without actually recomputing the clip. So it still considers the full original pixel data/count as 'the file' for any further sizing.

 

Manual sizing works like Set to ... it works from the original pixel data.

 

So the only problematic option is the one called 'scale to framesize'.

Thank you, Neil! Some of the terminology might be a bit over my head, but let me see if I'm understanding correctly...

 

Use the "Set to frame size" function to conform a clip to the timeline frame size (never use scale to frame size). And, that will maintain that relation if I end up needing to change the timeline frame size for the final export—even if I key frame a push/zoom move, etc..

 

So, if I'm working in a 4K timeline and I want to punch in on an 8K clip:

 

a) Add the clip to the timeline

b) Right click -> Set to frame size

c) Adjust the scale in the effects tab (percentage, key frames, etc.)

 

And, if I end up needing to export that 4K timeline in 1080—or 8K—I simply open the timeline settings, change the frame size, and all my scale adjustments (key framing, etc.) will be preserved without having to manually go back and make adjustments to account for the frame size difference.

 

Am I'm understanding that correctly?

You got it!

 

Well, mostly ... except for the export part. You simply export at a specific framesize in the export, and Premiere scales to that framesize. You don't need to change the sequence.

 

Now, some upscaling is possible, but you might find taking 1080 media to 8k might be a bit pixelated ...  😉
