Exporting H.264 Files Larger Than 4,096
on May 24, 2016 at 11:58:48 pm

I'm creating some content for a 1x5 screen marquee that is supposed to play 1 video file. In theory, this would be a 9600 x 1080 file. We are currently doing some testing with the file sizes as there are concerns with the player being able to handle that large of a file. I'm trying to export the file at 9600x1080, 8192x922, and 5000x563. The problem is that the files are supposed to be H.264 for this media player. If I export with After Effects, I can preserve the size, but H.264 is not an output option. If I export with AME, I can use H.264, but the size is compressed to no larger than 4,096 width. There used to be a way to use the deprecated formats in After Effects, but that doesn't seem to be an option anymore.

Does anyone know a way to take off the size limitations in AME or be able to export in H.264 from After Effects CC 2015? I would just convert it, but the file size is crashing the conversion software.

There is no profile in the H.264 standard that supports video wider than 4096 pixels.

What software/display system are you using?

Hi.
The 2019 version of Adobe Media Encoder will allow you to export up to 8192 pixels wide. However, its touchy when it comes to the aspect ratio. For instance, I can export an MP4 that is 8192x1536, but when I've tried to export an MP4 that is 5760x1080, it reduces it down to 4096 pixels wide.
I have to export videos for large screen arrays, and if anyone can suggest a resource that has more info in that area, it would be helpful.

AE is a compositor. Why not compress outside of AE? Quicktime pro does a fine job(though not the best), but for my money ffmpg is crazy fast, completely flexible and has no limits except the overall 264/265 specs. We're routinely doing massive sizes that would make AE cramp. Did I mention ffmpg is free?

You should speak with the technicians responsible for playback. Different systems have different specs, and we can only guess at them here.

And don't forget the screens themselves. Color gamut settings, black level settings and backlight color temp (both LEDs and LCDs) can all have an affect on what you have to deliver. The onsite guys love to point fingers back at the content creator when in fact it's usually them not knowing their own poorly setup hardware. You really have to get in there and investigate the playback and screens aspects to make sure WYSIWYG.
