Smaller resolution
by Hermann Haf on Jul 23, 2012 at 12:32:11 am

Hello

Im trying to make a video 5x28 in AE but the program automatically resizes it to 16x28, is 16x16 the minimum?
Is there no way to make it 5 pixels high?

And yes I know its a really small video, its for a pixel art video on a building.

Well, I checked in CS5 and CS6 and the smallest resolution available in both of those is 4x4.

What version are you using?

Hm, lets me do it in CS6 and CS5.5 without an issue. Do you have "lock aspect ratio" unchecked?

And this is what I get when I save as a movie from the render output settings:

Im saving the movie as a quicktime movie.

Most, if not all, lossy compression codecs require the frame size to be divisible by 4, due the way they work. I don't know off the top of my head if there is a codec which will allow you to export a frame size that's 5 pixels horizontally, but you could try uncompressed formats like animation. Note that this maybe a issue for final delivery, depending exactly in what you're going to do with the animation.

Indeed, this is not a limitation of AE but a limitation of the codec you've chosen in the output module.

[Hermann Haf] "can you guys recommend any other codec I can use ?"

That depends on the system you are delivering to.

How are you actually going to use this output?

Its for a pixel display on a building, same building as in this video:

The output has to be AVI and 5x28 pixels.

See this post for some detail about output constraints:

In this thread, Tim Kurkoski goes into a lot more detail about the constraints for AVI files:

Thanks, this workaround posted by kelly_hanson at forums.adobe.com is the best way around this I guess :)

It's not ideal, but we've been using the process below to make it work. It adds a couple extra steps, but as of now, it's the fastest way we've found to get around the issue.

In After Effects:
Render any comps smaller than 32x32 as an MOV. .mov files will render in sizes smaller than 32x32 without adding the black bars at the top & bottom

Drag the rendered .mov files into Photoshop. Set yourself up an action to export the files back out of Photoshop as an uncompressed avi. Give it a function key (F3 or something for a tiny bit of added speed - especially if you are doing a LOT of files like we do) and it'll export the file, with the original file name but in .avi format.

Again, it's not ideal - but that's how we've been getting around it.

Hope it helps!
