Well the title pretty well sums it up. I'm using Lightwave 8.2 to put together a short animation, and I'm not sure what resolution to render it if I'd like it able to be projected without looking like crap. Also, what encoder should I be using when rendering? I thought the answer would be easy to find open-source, but surprisingly I didn't come across it.

Talk to whomever is doing the transfer to film. They will have all the specs you need to work with THEIR SYSTEM. Everyone is a little different and this would be the MOST critical step to have it come out correctly. Most likely they will say to output sequenced images of some kind. (TIFs, PNGs, or the like. NEVER a lossey format like JPG!) hope this helps. Good luck with your project! :D

If you are going to put it on a DVD and use a video projector then 720x480 for 4x3 or 720 x405 for 16x9. Even though video projectors have a higher resolution 800x600 or better, if the source is not a computer but a DVD player then there is no point to render any higher. Full frame are nice, but it will eat you hard drive of space. Any encoder that is 100 percent will be fine. Most have adjustments to change it from 100. Make sure the settings are at 100%. Dale

DALE: >If you are going to put it on a DVD and use a video >projector then 720x480 for 4x3. ------- The output from the encoder should be 720x480, but the output from your 3d app should be 720x540 (or 640x480). Note that 720x480 does NOT equal 1.33(4x3) ratio, rather it equals 1.5 - yet your TV IS 1.33(4x3)?! THis is due to the much discussed difference between computer and Video pixels. If you render 720x480 out of your 3d app you'll get tall skinny figures.

Yes, you are right. I don't use 4x3. Dale

None of this address's the fact that richardnovak77 started off asking about FILM resolution, not DVD resolution. If in fact he's sending to FILM, then he should talk to his Telecine service. If in fact he's outputting for DVD, then the 720x540 figure would be fine for 4x3 imagry. For footage that is 16x9 going to DVD as LETTERBOXED, then output as 540x304. Since a DVD does 16x9 letterboxed as black borders above and below a 16x9 image CENTERED inside a 4x3 overall MPEG2 file @ 720x480. For footage that is intended for 16x9 ANAMORPHIC DVD, then output as 1440x720. This is 1280x720 (16x9) with the extra pixel width for the square VS rectangular pixel problem. Hope this helps!! :D
