Does sequence pixel size in PP matter for a bigger export?
Hi,
This week i made my first timelapse in Premiere pro 5.5 on a Mac.
I made it 1620×1080 to keep the 3:2 photo ratio, and to play it as big as possible on HD players (with 2 small black strokes at the side).
For this project i kept the imported photo’s at it’s original size (5616×3744 or some copped a little in 3:2 without extrapolation) because i wanted to use some Ken burns effect.
In the end i exported the sequence as a QT mov with Prores 422HQ codec. It looks great for shapness, although QT plays it too bright with not enough saturation. This is another question than the one i wanted to post, but solutions are welcome (i can’t find anything about profiles or gamma in PP or QT, and it’s made on a mac for a mac, so why would there be gamma shift or something like that)?My question:
If i do another export with a higher resolution (for instance my monitor resolution 2400×1600, or even higher in future when new projectors / tv’s with higher resolution than HD arrive) does PP take my original (even much bigger) jpgs, and scales it to the new resolution, or does the sequence setting have any influence, does it interpolate a 1620×1080 to something bigger again (but smaller than the original jpgs).
So.. does the sequence setting matter in terms of quality (or other things), and do i need to make a new sequence first with the right resolution, and copy paste my timeline?
I hope not, because of all the scaling, positioning (Ken burns) etc. Or is there a trick?
How do you handle this “future proof” issue? Or is it no issue? I can understand that with film the luxury of this much pixels is not that common.It’s all the same aspect ratio (3:2) if that matters, and the rest of the settings is also the same.
I hope someone can help.
Thanks.

By reading your post I assume you are using Jpgs instead of video, but I think that you should create your sequence according to standard video formats.
If you want to go higher than 1080p there are some 2k and 4k sequence presets. There won’t be any TV with higher res than 4k in many many years to come because there is not even one in the consumer market right now. You will be future proof on 4k for sure.
*Tip—–Your video will be more attractive on 16:9 aspect ratio (although is not a rule, many people prefer this aspect ratio for videos, and is currently the HD devices trend)
I don’t understand why you need Ken Burns for a time lapse, but I understand how much keyframe torture will require to match your movements on a different sequence setting.
My advice for that would be to do all of your work in a 4k sequence, or the higher setting that your pictures can fill. After you finish everything, just export in different flavors(4k, 2k, 1080p, 720p etc)I hope this is helpful.

Thanks Axel for your answer,
Yes, i used jpgs instead of video.
Thanks for the tip to work with a 2, or 4k sequence next time. I assume, the same sequence setting….sequence setting:
23,976 fps
1620×1080 pixels
square pixels (1,0)
No fields (progressive scan)… will do with a changed size (instead of the 1620×1080)?
I hope this still works smoothly.Does the preview resolution have to match the project resolution, or can it be smaller for working speed?
So thats the way to go next time.
But for now i already made a 1620x 1080 sequence.
So i guess you are saying the sequence setting do matter for the export quality?
If i fill in a higher resolution with export it enlarges (interpolation) the sequence pixel setting instead of scaling the much bigger source material (the jpgs)?
Just to be clear..What did you mean when you said you don’t understand the need for Ken buns? A matter of taste?
About the 16:9 vs 3:2 ratio.
I like to use wide angle a lot, and i feel it’s a waste of this angle sometimes (smaller spaces, not being able to take more distance, missing the top of a building..) Therefor i would like to use my whole chip.
But when i will combine photo and video i will go for 16:9.Thanks,

When you work with 4k sequences your pixel res will be 4096×2304. If your original Jpgs are big enough to fit this size without loosing too much quality then that will be your best preset.
If you start with 1620×1080 sequence, and export to a higher resolution, you will loose quality, because Premiere will bump up the scale to fit your desire frame size.
For example, if you have high resolution Jpgs, and your desire is to have several versions of the final product with different flavors(2k, 1080p, 720p etc) the best choice is to start from your original footage resolution and then down compress the final edited video, but never the other way around.
Here is a table with all the settings, please check it for accurate reference: https://en.wikipedia.org/wiki/List_of_common_resolutions
Premiere has native 4k sequences and is higher than 1620×1080.
The preview resolution is just for faster editorial process, you can change it to match your computer power, and if the bad quality hurts your eyes, there is a paused resolution option that you can keep high to see how your footage really looks.If your are making a time-lapse I assume that will be easier if you put all the Jpgs one after the other on the sequence, export that as a video and then apply Ken Burns to make it look better. Maybe I’m just thinking about a different type of time-lapse…… never mind.
About the 16:9 vs 3:2 ratio….. If your final product is a video, I recommend 16:9, if you are using a FULL FRAME sensor camera, then probably you will get 16:9 images natively.
I hope this is helpful, after picturing in my mind the issues you are facing, and trying to think how to fix them I feel the need of seeing the final product. At the end of the day that is what makes us feel good about spending money and time doing what we do.
Good luck
