Animation res

Depends on what kind of a TV it is. HD(and what resolution) or SD?

But I am assuming you'll be burning SD DVDs, and you live in England?

DV PAL 5:4 is 720x576px with anamorphic pixels for 16:9 and 25fps.
HD goes up to 1440x1080px with lots of variations but the pixels are square.

btw. widescreen generaly means 16:9 aspect ratio. Unless your talking about computer monitors.

 

If you're creating for PAL Standard Definition widescreen, then if render time isn't an issue I'd suggest outputing your renders at 1024x768 at 50fps, this will allow you to bring it into a compositing app (After Effects etc) or editing app (FCP etc) with square pixels and a full frame of information for every interlaced field. This method will allow you alot more breathing space for time remapping and other effects before you get noticable quality loss. When outputing from your compositing/editing app you should then set it to a standard PAL widescreen template (720x576, 1.42:1 lower field first).

If, on the other hand, render time is of the essence, and your 3D app (and compositing/editing app) support non square pixels and interlaced rendering, then your output should be 720x576, with a pixel aspect ratio of 1.42:1, you should also set it to output lower field first.
