Can AE or AME export mp4 wider than 4096?

[Dave LaRonde] “It is wise to get all of the delivery specifications BEFORE these decisions.

The most importanty consideration is this: how will your AE animation be played back? You mention multiple screens: what is/are the playback device(s)? What kind of files do these devices require? At what frame rate must you work?

I think you are a long way away from deciding on one or more mp4 files.

Well, you are right of course, about potential issues with these delivery specifications. Mainly, whether they playback system, which I guess it’s a PC, can deal with these high resolutions and bitrates without stuttering. So far, I’m assuming the client knows what he’s asking (yep, that part is probably naive), so I’m working with the resolutions they’ve asked and the .mp4 wraper they also asked. But the client specifically asked for a single .mp4 file.

There is no H.264 profile that accommodates those widths. A compliant encoder will not make these files.

In my experience, wide displays like this are often pre-split, but of course it depends on the playback system.

Yes, H.264 won’t cut it, I’m using the older mpeg-4 through Compressor, which works. And, yes, the video will actually be split in half, with two sincronized devices controlling 3 monitors each for the 8160 pixels wide one and two for the 5440 one.
However, the client wants the full sized file so they can “preview” how it would look, despite the fact they’ll have to scale it down to actually see it. Oh, well…
