Smoothing nodal pan by re-timing, by calculating a tracker's velocity over time
on Sep 27, 2011 at 10:28:09 am

Hi guys!
I have a mind boggler (well, for me :P.)
I have a jib shot which isn't very smooth (not a nodal pan, that was just to help thread title), the camera keeps speeding up/slowing down. I need to smooth this.
Because the subject matter isn't sync-sensitive, I'm speeding bits up that are slow, and slowing bits up that are fast as a way to average the camera's speed to smooth the shot

So theoretically, my re-time value is inversely proportional to the camera movement.

I have a motion tracker which I have to help me visualise where the shot slows down/speeds up.
How would you go about mapping the change in velocity of this tracker into a percentage value of the re-timer? 100% being the average value which i'd pre-set I'd guess, and the speed change would be relative to this.

Any ideas?
Thanks in advance by the way :)

I have the same exact issue. Did you ever figure it out? I would love to know if this is possible.

Thanks!
