I was wondering does anybody have any experience controlling frame rate with the speed curve of tracking data. I am sure it should be possible to have a linear camera move rendered out at a high frame rate (provided the distance rendered is the same as a live action camera) and have the speed of a live action track control the frame rate to get the appropriate ease in and out. Any help with this would be greatly appreciated.
It depends… if you're tracking 2D data, the position of your track would indeed have a linear relationship to distance traveled. You can integrate and scale that by a value that is dependant on the actual amount of mpixels travelled. Easiest would be to tweak that value with a slider.
Something like the attached expression would work (in theory !).
Maybe checking the speed at every frame-duration wouldn't be accurate enough, just change the fd = line and adjust scalingFactor accordingly…
