Subject: Frame rate for BVH files?
24 or 30 FPS seems reasonable. Anything lower might be choppy. Anything higher is just icing on the cake. :)
C makes it easy to shoot yourself in the
foot. C++ makes it harder, but when you do, you blow your whole leg
off.

So then the forumal I would have to use to figure out how long my animation is T=Fr/F (Time=FrameRate divided by Frames)? So if I wanted a 30 sec bvh file I would want 900 frames at a 30 Frame rate?

Yes, exactly. But Time=Frames/FrameRate (30s = 900f/30fps). To solve for frames, multiply both sides by the divisor (30fps). So, 10 minutes would be 600s. 600s*30fps = 18000f. Makes you wonder how they do these feature-length movies in 3D CG, huh?

Considering took me almost 9 hours to do a 1minute BVH test render in Carrara 5 (view here)

I am running in to 2 problems with a BVH file I am working on. One is running too fast and the other is too slow. I have the frame rate set at 30FPS on both one is a 235 frame (fast) and the is 95 frame (slow). Anyone have an idea?

You need to try to find out what frame rate the bvh was recorded at and adjust your timeline accordingly (stretch or squeeze the keyframes) or just try a few settings on frame rate until it looks good , then use that for your conversion factor
30 fps is typical video , 24 fps was typical film
15 fps works fine except for high speed movement and may be ok with a motion blur effect .
carrara changes the frame count when one changes the frame rate, to keep total
time constant. but it does very smooth gif-animations (smooth colour gradations) IMVHO.
anyway, if some other video format is being used and the two videos are being displayed
at different rates (even tho they have the same frame rate), then it's some bit-rate limitation
of the graphics card AFAIK.

Frame rate on both is suppose be 15fps but when I opened them in Life forms (my new favorite tool) I found the first was 24FPS and the other 30 FPS.
I was able to use Lifeforms to match the desired speed.

What is the best frame rate to use when creating a bvh file for any figure? I am trying to make a BVH file and want it too look fluid not choppy like some I have seen.
