Codecs for a very very large video format?

[Matthew Woods]

I agree with David, you shoudn’t expect to be able to play a file that size, but I do pre-render multi screen movies like this prior to cutting up. I usually use Photojpeg at 95% quality. This codec jpeg compresses each frame, so it works well with any frame size. As long as you don’t need to chromakey something on it, it makes a good semifinal pre-render codec. This seems to get me adequate quality while saving a lot of file size over lossless codecs.

For workflows like this, you must start at the display and move baclwards.

You deliver whatever the playback system requires. As the othes mentioned, that may involve pre-splitting your output.

You should check in with the AV vendor responsible for the wall.

Thanks for your responses

We will not use a single video for the final output. The AV engineers have asked for one full resolution piece of 10 seconds just for their testing purposes. I was trying to make it for them but was only able to get insane output sizes, perhaps because it is insane to begin with.

Building separate pipelines for tests and production is very risky! Engineering tests should cover the entire production workflow — otherwise, how can you confirm that your outputs and compression settings are correct?

By the way, for my own internal pre-renders and proxies, I almost always use image sequences for large video walls. Since the render times are so much higher on larger comps, using image sequences in your workflow will let you easily resume failed renders, or re-render only small portions of longer comps as necessary. A large, fast RAID will help.
