#Render Frames vs Fields

I was talking with a video expert this morning who told me that rendering to fields as opposed to frames makes a very noticeable difference in quality (mainly smoothness of motion) when putting animations on video tape. I haven't ever seen this mentioned in this forum. Can anyone vouch for this? Should I go back and re-render my animations for my demo reel?

Why don't you re-render one of your animations to fields and compare… you'll never again render video to frames 🙂 Think about it, your animations will be twice as smooth when comparing 60 distinct _stills_ as opposed to 30 in that second of time.

Tyler, rendering to fields mkes a HUGE difference in object motion smoothness for video! When rendering to fields, the renderer takes advantage of NTSC's 60 field/30 frame per second frame rate and actually calculates TWICE the motion data than when rendering to frames. Twice the motion data means animation that is twice as smooth – especially noticeable when your animation has lots of motion. Go for fields and have a blast, -Alan

>> re-render my animations… In addition to the other comments you've received, be certain to render fields from the -keyframer scene- and not just video post your existing frames with fields on. What field rendering does is interpolate positions between frames to produce 60 separate fields per second. Frame rendering does 30. – Dave

David, Is it possible to mess up the fields by rendering an animation in segments that are later combined before going out to tape? (Anyone else can also comment on this.) Mark

If you are "combining" on a field-sensitive piece of equipment, and everything is rendered correctly, you have an excellent chance of having no problems, Mark. I imagine there are some problems that could be present, but I'd have to see the piece… -Alan
