Rendering Interim Frames?

I have rendered out an animation and composited it in After Effects. For a special part of the animation, I need the information from interim frames – around 3 or 4 frames of information BETWEEN each rendered frame (kind of like how the non-vector motion blur works, but outputting each frame as a separate image, non-blurred).

I know I can just slow down the animation, but that involves a lot of keyframe tweaking, and it seems that a solution is probably sitting right in front of me… If I only knew where to look. (I tried setting the “Frames per second base” setting from 1.0 to .25, but that didn’t seem to work…) Any ideas? Thanks!

Is this a slow motion section of the animation?

So if you rendered the animation at 30fps then you needed to render at 120fps for that ‘special’ section?

Could you use an After Effects frame blending mode to generate/interpolate new frames?

Or re render the section of the animation? Easier to do if it was rendered as image sequences?

@yellow: Yes, I’m doing some time remapping in After Effects; the timewarp/pixelmotion feature of AE handles most of the interpolations fine, but there is one particular section that is causing me a lot of trouble (the images change too drastically from image to image). At the moment, my best solution is to shift the keyframes in Blender and rerender everything at about a quarter the speed, which works fine – but it feels like there must be an easier way to get these sub-frames. Some feature or script that allows me to render between frames…

Your using pixel motion already :frowning:

I’m out of ideas, not that experienced with such a problem.

What frame rate did you render at?

If it was 30fps, have you looked at the results of pixel motion but at 24fps playback, I have no idea whether it would help. lol.

Atom’s an AE / Bender man, he may have an answer.

Hi,

In the Scene button window (F10) select the Anim/Playback buttons. If you leave the Map Old value at 100 and change the Map New value to 400, you’ll slow down everything to quarter speed. You’ll need to change the frame range and work out the frame numbers you need to render (i.e. multiply by 4), but this should give you the results you need.

Isn’t that just step printing? No interpolation? It certainly would be good if it is that simple.

Holy Smokes! Perfect! Thanks rawpigeon, thanks yellow! A terrific blender gem!
