scaling object frame data

#1

Gretings,

I brought in .bva motion data, 1000+ frames, at 10fps. They come in as object frames. I need to scale them out to 30fps, having EI interpolate the new frames. How?? Also tried in Excel without luck. Any ideas?

thanks, Tim

Hi Tim,

A couple of things I would try, change the project frame rate to 10 before you import the motion, then change it to the required frame rate afterwards.

I have no idea how that would work, but seems like it would be worth having a go at. The other way is to select the animated group, go to the animation menu, go down to ‘fit selected group to curve’ or some such option (I don’t have EI in front of me). Choose a tolerance of somthing like 0.0001 to ensure accuracy, your group will now be animated in a way you can scale.

Again with EI not in front of me these instructions are going to be hairy. To scale keframes:

  1. Select the group
  2. Put the timethumb to frame 0
  3. Hold down the command key (Mac)
  4. Drag the time thumb to the end of your animation (I actually have no idea what this does, but you need to do it -) It will turn the timeline blue.
  5. Select the keyframes, hold down the command key and drag the last one up the timeline (to scale up), this SHOULD scale them. I say should because this is a fussy feature, it sometimes requires some messing around.

If that doesn’t work I’ll have another crack at these instructions with EI around :slight_smile:
Best,
Ian

Thanks Ian, but I don’t have keyframes, I have object frames (the underlined ones). So I think I’m stuck as far as EI goes.

Got it figured out. Change to Explicit, select frames in Keyframe mode, Animation-Fit Selected Objects to Curve, this makes it into keyframes. Then scale time in Animation Offset Editor. Probably can scale as you described as well. Easy peasy (once I figured it out of course).

thanks,

Tim
