HI all,

I'm having to render my animation in scanline because of time constraints. Can you guys suggest good settings for a happy medium of quality vs. time (Catmull-Rom, Hammersley, filter size, etc.)?

I'm rendering 720 x 480 at 1.2 pixel aspect ratio (for DVD).

I want the antialising to compliment the motion but not kill my PC.

Thanks.

Did some more searching, and found this great article on speeding up, and optimizing for scanline:

have you done any test yet to see how you footage will look after you compress it, make it an MPEG2 file, then play it back on a TV?

do that and then see what you need to change. how you compress it and what software you use to do it could really affect the image file, may even blur up the edges of things for you.

I know when I work with DV footage, I have to really, really, blur down my CG footage to look anywhere near what crappy compressed DV looks like.

Thanks for the reply michaeljr. I read from the article above that for rendering to video, regular TV (NTSC), that the "video" filter is best (it blurs). I don't yet know what it will do on a hi-res 16:9 (and I won't until presentation day). I'm rendering out a test tonight that will at least show me the NTSC.

I have many stills that will get rendered as well, and those will be done with MR and some super sampling.
