Question

Exporting large files in AE

Hello

I'm having trouble exporting large files 18288 x 56px, 30824 x 72px into avi files using AE.

These files will be used for LED banners in stadiums.

I know AVI isn't supported in the latest versions of AE ( i have a Mac). So I'm using Wondershare to convert .MOV to .AVI but it becomes glitchy when converted. Has anyone else had this problem?

I've also read the the maximum canvas size is 30000 x 30000px. Is there a way around this?

Any help would be great.

Thanks

I just received a request for an uncompressed AVI video 1776p H x 96p W for animated graphics to display in a stadium. The client was very specific about this, so I assume that is what they need.

I am working on a Mac with OS High Sierra. I need to know how to encode to AVI from whatever I render from After Effects/Media Encoder. What tools are people using these days?

    First as Doc Maik mentioned - it is hard to believe that they are using one clip/one signal - prepared as you describing - and feed that to stadium banner. I worked with those kinds of screens and setups as a technician and I also delivered footage for them several times and I never seen delivery method like that. So first thing I would do if I would be you - I would contact tech that is responsible for that banner or company that put that system there and ask for exact specs that they use. In post cases they use pixelmaps that fit into standard resolutions (full HD/4K) so you prepare final product as that pixel map and then delivery system that they use split and deliver exact sections to exact parts of that banner.
    Bellow example of a pixelmap of gate like screen setup that I worked on several weeks ago:
    - animation was one large projection around and inside of that cube

    but what I was delivering to client was this (2 full HD movie clips):

    But let say that you have to export file with specs that you mentionned so AE can and will make that lower res for you without any issues, but as for larger one AE is restricted to - as you said - 30K px. But even if that would be possible  then you have to find codec that can handle that kind of resolution in avi container (because you said that it have to be avi) and that will be hard.

    Thanks Imeilfx, that makes a lot of sense.

    You've just introduced me to a world of pixel mappings.

    I'll try and speak to the tech guy.

    Yes do that. That way you will save bunch of time preparing your comps correctoy from the start and you will make technician that works with that led baner hapier by giving him exactly what he need

    I can't image that anything on this world when being printed and or being a display, has 18288 pixels in width and is one piece. No display is that wide. If it fails, you would have to replace the entire piece, not just a part. So the banners most likely will be split in many pieces, so can the exports.

    Alternative: use the AME, it may have different specs. AVI is furthermore only a container, where the codec also matters, but didn't mention which one you tried. So the question is, does the AVI container have a problem with that size or the codec?

    You're right Doc, it surely would be in panels.

    But these were the dimensions given to me by the client, along with 30fps, 72dpi and .AVI requirements.

    I have tried AME and that doesn't help either- it reduces the dimensions smaller.

    The Wondershare codec I've tried DivX and Xvid.
