Rendering half the frames of a symmetrical movement.

[Tom Wood]

Hi All,

I have a character that will be making a series of symmetrical movements that always return to the start position. For example, a slow turn of the head to one side and back might take two seconds, or 60 frames. Since the motion is symmetrical, frames 31-60 are the same as frames 1-30, but in reverse order to each other. 1 and 60 are the same, 2 and 59 are the same, etcetera. How can I render only the first half of the movement and automatically add the other half of the movement, post render?


Thanks,

TW

If you don't use field, maybe u can copy, reverse and rename your frames with a tool like "renam-it".

else, post render seems to be the better way.
Reverse the footage...maybe, u have to reverse the order of the fields too (Even/Odd)...

If you are using Premiere, drag your 30 frames into the timeline, then do it again... selecting the 2nd clip, make the duration (Clip - Duration) a negative time...

edit...
on second thought, unless this character is a robot, it'll seem a little stiff
