Using PI at HD resolutions?
on Oct 30, 2006 at 9:43:55 pm

Hi,

I was wondering if anyone is using PI to creat animations at HD resolutions like 1920X1080 and if so, if they have any advice.

Thanks,

Eric

We've been using PI to create files in various HD resolutions (1080, 720, etc), as well as in some VERY large resolutions like 5120 x 768 and 8400 x 1024. These were for an enormous screen being erected as part of the Olympic games in Beijing.

Here's the first key: In order to successfully render at the desired size, you have to have enough monitor desktop room to display the stage window. So if you are going to render out at 1920 x 1080 you have to have something in excess of that. For instance if you have 2 monitors hooked up to your station with an available resolution of 1920 x 1080 or better, than you will be fine. In some of our cases we had 5 such monitors hooked up by using multiple SLI graphics cards. So thats point one: have enough room on your monitors to see the space.

Point two, is that many of the emitters natively show up at a size that may or may not be right for composition in HD sizes. So be prepared to set aside time to re-work emitter sizing (which can involve tweaking quite a few attributes) in order to get things where you like them.

Point three (and I've just firgured this out), is that HD res has room for lots of particles, and lots of particles make extraordinary demands on your processing power. When you get down to the nitty gritty of tweaking and setting key frames you might find that things slow to a crawl. To get by this, turn off particle display in your view menu. Then make setting adjustments, and turn them back on. This way the computer is not trying desperately to catch up with you while you make adjustments.

Have fun,

Bob,

Thanks for your thoughts. Isn't there a limitation on the stage size to 720X486?

No. pIllusion itself has to render in a visible window (at this time), so your stage window has to be large enough to fit the stage area you want.

You can also just work in pIllusion zoomed out (so you don't need 5 monitors!!), then do your full-sized render in pIllusionRender. On Windows this can be quite slow. On Mac it's much faster, but you may be limited to 2048 or 4096 depending on your video card.

That's a really good point that's easy to look over. I did a tutorial a little while ago that focuses on the steps for resizing background type emitter for HD. Won't help you with all emitters, but it might come in handy.
