Hi,

While I have been using Poser for many years (currently using Poser 11, considering upgrade to Poser 12), this has been for creating still renders to illustrate eLearning materials. So when it comes to animation and video output, I am still an amateur.

One eLearning project designed to help users to reduce PTSD (I am a social worker who creates helping materials), originally illustrated by still renders of a car accident scene, would greatly benefit from using an animated video of such a scene (car driving along, sunny day, collides "out of the blue" with another car and driver, injuries, ambulance takes away the injured driver, last scene at hospital, recovering, ready to go home).

So, I take my first still render (car and driver), key frame it on first frame, then move it to the other side of the stage at frame 30 (or 60) also key framed. Haven't yet played with rotating the wheels. But, at almost any frame rate, high or low or in-between, get a motion blur that makes the video output look stuttering rather than a smooth ride across the stage. Tried lowering the aperture speed of the main camera, many other attempted fixes, but no joy. Still get a mildly choppy video of the most basic car driving across stage.

Not sure what else to try? Any help, suggestions appreciated.

You'll need to be careful to distinguish between motion blur and stutter.  If you see motion blur, look for this box in render settings and un-tick it.

If the individual rendered frames are *not* blurred, then look for unwanted keyframes:

P.S.:  I recommend that you render a series of individual frames in PNG format, then compose those in a video editor.  While Poser *can* output a video, if anything goes awry, you lose the entire animation.  If you render separate frames and suffer a crash, you still have whatever frames have rendered and can resume from there.  Also, you can adjust the compression *after* viewing the effect in a video editor.

Thank you very much, seachnasaigh, for this detailed reply and suggestions. Much appreciated!

Will give these a try, update with results. (May take a while to re-export as PNG's.)

Best Wishes,

Update: am experimenting with a series of 30 PNG's rendered out from Poser, composing to video in After-Effects. Still getting motion blur at 30 FPS (30 PNG's, rendered in Poser frame-by-frame). Hopefully can solve the motion blur through editing in AE.

60 Second Commercial by Richard60 (renderosity.com)

Above is a link to a video I help make.  At the beginning is a camera pan which is too fast and probably has the stutter effect you are talking about.  The last part of the video has a car driving at 360 MPH (totally unrealistic) the total course for the path of the car was 1.2 miles.  I think the car movement is nice and smooth.  Doing the math for your car, for 30 frames (1 second) @ 60MPH (reasonable speed) then your car could only move 88 feet, or about 2.9 feet per frame.  Even with my super high speeds (360 MPH)  the car only moves 17.5 feet per frame.  The average car is about 20 feet long.  So at your speed the car should be over-lapping itself for about 7 frames.  Even with my speed the car over-laps frame to frame.   

Hi Richard60,

Thank you for sharing this excellent example, plus helpful suggestions regarding how far a car can move at a specific speed. I had been thinking about this but until reading your posting, I didn't know how to devise a solution. So, using these suggestions, I will experiment further, try to get my animation to work better. Thank you very much!
