Adobe Illustrator Puppet Size?
I've been learning how to use CA now for months and I'm really enjoying the process.
I created a few puppets and today finally got some of the scenes into After effects for video editing- but my backgrounds and closeups (of my puppets) were pixelated. I know this has to do with the correct sizes for the puppets in Illustrator- I've been creating them at 3000x3000 pixels, shouldn't that be big enough? I saw in a tutorial video that the puppet was mad in 1500x1500pixels size, and it didn't have any pixelation (I think the tutorial was making a video for youtube- my video was an HD full version so maybe that's why I'm getting pixelation)...
What is the "best" puppet size to use when creating one in Illustrator? I have a new iMac so I'm not afraid to push on upping the size so as to not get any pixelation...
