Banding and artifacts assistance needed!
on Apr 1, 2015 at 10:38:06 am

Hi guys! I need a bit of help- it's probably a really simple problem but I thought I'd ask your opinions.

I rendered out a small animation in AFX and there are a lot of banding and artifacts issues, as you can see.

Can someone help me sort out this problem? It's quite distracting!

What kind of file did you render out of AE: media container/codec?
What is the bit depth of this AE project?
Are you working with solid colors or subtle gradients in the trouble areas?

And as always....
What's the PRECISE -- down to the very last decimal place -- versions of AE and OS you are using?

Hi there- Right, I'm using AFX CS6, version 11.0.0.378, I rendered out still pngs of the puppet in the moving part of the image and imported it as a sequence in Premiere Pro CS6, where I put it up against the still background (which is also having noise issues). I rendered this out as an animated gif.

My OS is Windows 7- not sure what decimal this is.

I am working with solid colour. "Auto Color Display" is selected in my bit channels.

Here are a few things:

Your CS6 is a few updates behind. It's wise to stay updated:

Make sure you have Service Pack 1 for Windows. If you don't, get it.

Double-check how the images look in PP. No noise? Then it's not AE's doing.

Animated GIFs aren't the greatest at color fidelity. The noise could be happening as you encode for GIF. Since you're working out of PP, ask on the COW's Premiere Pro forum about the proper way to export animated GIFs. You may discover there is a much better file type to which you should be exporting.
