#30fps or 15fps for PAR

I'm just curious if any of the experienced PAR user would recommend to render "by 2" or "by 1" [on the frame parameter] when going out to PAR. This will translate if whether I want to play it back at 15fps or 30fps. This saves a tremendous amout of rendering time w/ "by 2" method. I notice that rendering "by 2" & p.b. @15fps on camera movement scenes tend to be "jerky & stroboscopic looking" This all I'd experienced so far and just don't fully/thoroughtly understand the reason behind it. Any comments/tips are appreciated. {CSNavigator automated message} – TSL

Traditional 2d animators have used 2's for all but the fastest moving characters. 2's in film translates to 12 images per second. Even though 2's in video is 15 images per second it dosent seem to work as well for 3d work and often gives a jerky look when the camera is moving. I dont think it has anything to do with the par, its true for any type output. On the other hand Ive had folks that swear by field rendering ( 60 per second ) not be able to tell the difference when something is frame rendered. The composition of the scene is a big factor. For example, a light object moving across a dark background is the worst for showing the strobe effect. Since a lot of 3d work is space stuff or logos the jerkyness really shows up. In other situations frames or even 2's may work fine IMHO. Ed

Ah, thanks for the clarification and proper usage of the rendering procedure. Now I'm more aware of the frame rates. – TSL {CSNav automated, allow ~24hrs. read/reply.}

TSL: I use the 15fps and lower to slo-mo a particular sequence, good post prod. flexibility. However, I believe if you render out in 2s from 3-DS with the idea of saving rendering time by playing out at 15fps will result in very jerky animation. In fact, if your scene has movement, particularly on the horizontal, field rendering is my preference, because it is clearly that much smoother. jeffrey

Jeffery: Thanks for the inputs/comments/suggestions re the fps issue. I think it's inevitable to _must_ render @ 30 fps on 3d scenes for smooth results w/ moving subjects. (Automated, allow ~24 hrs for read/reply cycle.) – TSL
