Need help with 3ds max camera

#1

Hi to all the experts
I made a camera animation scene in 3dsmax that is moving above 3d objects using vray camera. I rendered it in 25 FPS (Pal) with png sequences. after I rendered the movie I noticed that the animation is not smooth, and its choppy, you can see it clearly when the camera moves above the red objects, and when it arrive to the logo, the animation result is not smooth and make me feel Dizzy. I made a preview animation in 3ds max, and I notice the same problem.
The Client gave me last chance this weekend to solve the problem.
I tried to render in 30 FPS, same problem. I tried also to render as Avi format and I got the same problem. I will be glad if anyone help me to solve this problem, I even can send to you the 3ds max scene file.

Nice little shot. What you need is added motion blur. Without it you get a strobe effects, especially in large moving shots like this.

Good luck.

Hi
Thanks for your help, I will try it. But My question is, there is no way to fix this problem instead of adding the blur effect? In another words, what cause this phenomenon to appear?
Is it because in the real world camera, it creates automatically a motion blur so we do not see this choppy, however, in the 3d camera, it doesn’t make this effect, because it is not a physical camera.

With a real camera you have something called a shutter speed that will basically take out more and more of the blur in the image the higher you set it. However, a specific amount of blur is needed to make the image look smoother. So the majority of films you watch, animated or not, tend to lean towards a 1/48 shutter speed, or in physical film cameras a 180 degree “shutter”. So yes a regular camera has the ability to take out nearly completely (in theory) the “blur” effect, but its actually sought after. If you don’t have it, your just flashing a bunch of pictures together with no relation between the last and the next.

I think it was on The Incredibles that Brad Bird said they had finally gotten to a good level of “film-looking” motion blur… Animators have to work a little harder to get good looking motion blur, but if done correctly (not too much and not too little) then the audience shouldn’t even notice it.

Freeze frame on any animated/non animated shot(where camera movement or action takes place mind you) and you’ll see that there’s always atleast some amount of motion blur, even the Pixar, Dreamworks, Lucasarts etc. Introductions all have motion blur.

I’ll be happy if anyone else give his opinion about this problem…
