vertical plasma screen question (but different to previous questions, i promise :-)
hi everyone … so we are working with a number of vertical plasmas screens for a multi-screen presentation … i’ve always been working at 576×1024, then putting into a PAL widescreen comp and rotating before rendering … this works great … except until now…
we are inserting standard SD footage into the vertical comp. But the new footage needs to stay the correct way .. so the height of my comp is 1024 and the height of the footage is 576. Now I’m going to have to scale it up to fill the screen… my question is:
If I was working at 576×720 with the correct PAR, I would not have to scale up as much and this would result in a better quality upscale … right? If so, does anyone know the correct PAR for working 576×720 PAL? oh wait, I just realised AE doesn’t let you put in a custom PAR! argh … am I stuck with upscaling to 576×1024 ?Any advice from people who have done this before would be much appreciated!
Thanks!

If I understand you … I’d drag the footage into a PAL square pixel comp. So now it’s normal-looking, but in square pixels. Then I’d drag that comp into the tall 576×1024 comp and scale it up. Then do your usual insert, rotate and render?

you can add/change custom PAR’s.
In case you’re using Windows;
in your AE/support files/interfpretation rules.txt you can manage source file PAR’s
and in your Adobe After Effects 7.0 Prefs.txt you can change composition PAR’s (do a search in your documents and settings folder)… but …
you will always have to scale-up “as much”
keep your files as-is and your comp in 576x1024square and AE will use sub-pixel upscaling and rendering.cya,

thanks for all your suggestions … i thought this would be the case, but was hoping there was something simple I was missing in the PAR conversions and such … will have to live with the upscale because a lot of this footage is older archival stuff ..
have tried a couple uprezzing apps in the past like Instant HD and have not really been happy with any of the results .. most of the time I could hardly even tell the difference between these and AE upscaling …
