AfterEffects renders lots of NOISE with LOW resolution composition
Hi CCows !
I’ve been doing a really simple animation with After Effects in a video which is 144×38 pixels (so, very small and tinny). When I see the preview on AfterEffects I see it properly as I designed it, so it’s a basic radio waves effect in Orange/Yellow… (see first image).
But I found problems when rendering this simple stuff as I get a lot of color changes and noise all around the composition !! (see second image). Even when you see the video running you can see the noise moving while playing, making it very unpleasant and unusable.
I’m willing to use this video to inject to some LED devices, where each pixel will drive an LED and having this amount of noise makes it impossible to use the rendered file.
Is there any way to render this kind of animations without getting this annoying noise ?
Is there any reference on how to deal with it ?
I’ve tried to use “Draft” quality settings to avoid anti-aliasing, I’ve tried the color depth and color profiles with not much luck …
Does anybody has an idea on how to handle the render of such contents ? (very simple, plain colors) keeping the “original” colors that I see on the preview ?
Thank you so much !

What codec are you using when you render? You may need to use a lossless codec to avoid compression and chroma sub-sampling. What specifically you should use depends on the playback system.

Hi Walter !
I need to encode it in AppleProRes 4444 as this is the code that I need for the player software.
I assumed that this was a “good loseless” codec, but it turn out to be very noisy with this kind of content/resolution …
Any tips for the ProRes 4444 avoiding chromatic noise ?
Thanks !

Use a lossless codec as Walter stated.
Then conform using ProRes4444 and see what happens.
I assume the ProRes is what the client requested.

Ok but what do you mean by conform using ProRes4444 ? Conform is like “transcode” ? Should I use AfterEffects to render from an uncompressed codec to ProRes4444 ? Sorry but I got confused with the “conform” meaning … And yes, ProRes4444 is what I need to have as final output, I can’t use for example “uncompressed” as my final codec…

Are you rendering directly to ProRes 4444 from Ae’s render queue?
I tried quickly recreating this, and my ProRes 4444 and ProRes 422 renders were clean:

WTF ?? That looks like great results compared to mine ! Is there any way that you can share a project with the settings and render queue where you got this results ? I assume that there is something I’m doing wrong somewhere around the project settings, color management or render settings ? Thanks a lot for trying it out Walter !
