Exporting large resolution

#1

Hey guys,

So I have a file I’d like to export at 2048x4096, and eventually I might need to export at 4096x8192. Every time I try to export h.264, it resizes the render to 2048x2304. Is there a way to stop h.264 from doing this, or is there a better codec to use?

An uncompressed avi will give me the right resolution, and I haven’t tried it, but I’m sure something like an animation codec would work too, but the file size is just too big and probably won’t play. I need something with a little bit of compression.

Any ideas?

Thanks!

Render an uncompressed master(which you should do anyway) and try encoding in Adobe Media Encoder or the like. Afaik H264 is resolution independent, so it might be an After Effects limitation.

Oh yea, I always render out a master dpx sequence first.

Media encoder didn’t work. Shot out an h264 at the same exact resolution even after kicking up all of the quality settings, and it looked like the other options were going to give me the same problem as well.

I imagine premiere will give me the same problem. Anywhere else I can export from maybe, if AE is part of my problem?

I rendered two versions of the same sequence(8000*4000)for test purposes - one QT animation, the other in H264. The animatioan encoded clip came out fine, the H264 one was clipped to 2000.
I tried to render an H264 from the animiation QT using Compressor and it failed.
I also tried QT Pro and it failed, giving me an error message

qtKitErrorCatchAll (-108)

As of now it’s looking like mpeg4 is the winner. It’s allowing me to output at the resolution I need, and even as high as 4kx8k. And the files size is reasonable, all things considered.

I’ve pretty much given up on h.264 for these files sizes. Maybe when h.265 comes out I’ll try again.

Mp4 it is then(same here). Good to know though I never had resolutions like this. What do you need that size for?

#7

Some 4k stereo projections onto planetarium-like domes. And for the stereo, they want it on top and bottom, meaning the 4kx4k projection becomes 4kx8k. The 2kx4k is just us testing things out at smaller resolutions.
