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 ...  😉

Thank you, Neil!! I very much appreciate your help. The quick respose is helping me understand this forum as an effective way of getting support—I didn't realize how quickly I'd get an answer, and Adobe's phone support is, well, they defintely try their best, but I don't think they're hired based on their knowledge of Premiere.

 

Thanks again!

Product Support staffer Kevin Monahan, who kinda oversees this site, and other things ... always says when you go through their formal "Help" system, and get a live body ... either computer chat or phone ... immediately ask for the "Video que" ... as that bumps you up to specialists, rather than the generalists you often get at first.

 

But yes, this forum at times can be very helpful.

I have an 8k clip and a few 4k clips. I'm trying to figure out if I should make an 8k timeline for my largest clips and make sure they are all set the the frame size. Then export at 4k or 1080 when I am done. Or do you make a 4k  or 1080 timeline and export from there? I just want to make sure all my clips are viewable at their best sharpness.

Using a smaller framesize for the timeline won't affect viewing sharpness unless under some circumstances if you're way zoomed in on a larger high-pixel monitor.

 

So most people would do the 4k. Although a ton of the pros I know say they nearly always are delivering 1080, so ... that's what their timelines tend to be.

 

Just make sure to avoid 'scale to framesize' ... as that raterizes the image to the sequence framesize, then does any other image sizing from that image. Basic scaling of the image always works, instead, from the original pixels when processed.
