[AE CS4] Best resolution for very large screen broadcasting

Zabriskie31 Jan 24, 2012 7:54 AM

Hello,

I have to make a demo for the Chinese New Year to make, which will be projected on a wall of 30 x 10meters! I started for 2 days on AE, and I suddenly wondered if I will not have excessive blur effects with insufficient resolution.

The video will last about 1 hour with a count-down, including the effect of "lightning" to be played continuously. In the final seconds, there will be lighting effects of Knoll Light Factory for the transition to the new year. I precise that there will not be JPG image and everything will be created in AE. Is a resolution of 720x560 enough?

Finally, the question of rendermode is a science in AE too, and I only have a 80 GB external HDD for the export of the final film. So what are the render settings needed with all these constraints to get the best possible result?

Thank you in advance

Well, you leave out the most important question: Which projector are they using? That's all that matters - from framerates to resolution to how to compress it for playback. Most projectors are at most HD, but will of course paly lower resolutions. It's just not going to look as great. Similalrly, most such stuff is handled by playing back the clip from a laptop, so this limits your file format selection to anything that said laptop can play smoothly, usualyl Windows Media or H.264. Everything else is not realyl soemthing anyone can answer in a simple sentence, even more so with no pertinent info to begin with...

Then you need to find out the maximum resolution of this projector. You need to find out the frame rate at which it works. Then you will know shat to do. I also recommend making a test video to play on the exact laptop and projector you will use to make sure all is well.
