Attached is a quick gear assembly I created. I performed a
motion stud on the assembly with a rotary motor applied to one
gear. The Motion study works beautifully when I click play. I
changed the frame rate to 30 FPS. I want to export this as a video
to email. When I click the save as video file button, the gears
appear very jerky, out of place, etc. See Gear Assembly-102. Any
ideas???
There is a setting to control the frame rate when you export, but it must be less than or equal to the recorded frame rate.
I also usually turn off the key frame option as I have seen that cause stuttering.
15 FPS output is reasonable for realtime viewing of animations normally.
One thing to be wary of when dealing with rotating systems is a stroboscopic effect where it appears that parts are stationary, rotating backwards or doing crazy things. This is where the frame rate is to coarse typically to capture the motion. For example, if you have something rotating at 3600 rpm, and just capture 60 fps, you will see only 1 result per revolution, so it may looke like the part is stationary. Check your simulation settings for what frame rate is set on the solve.
If you just want to see smooth animation, reduce the speed to capture the movement over a longer time frame
