Animation Problems

[snuurtje]

Hey, i just created my first animation, took a long time to render, and its just a first test.

Im not going with the color transistion anymore, have changed some things on the car, and will be creating a nice fade out on the end. My main problem is that moves a bit jaggy. I ofcourse couldnt see htis in my playblast, and i just saw it when it was completely finished (made it full HD :-/ ). However I really appreciate help on how to render this animation more smoothly, im working in maya btw, so some application specifics would be appreciated.

Other CNC is welcome aswell, since im going to do it over anyway.

here is the current jaggy animation.

The first thing I notice is an AA problem with the roll up door, it also looks like your wheels are not turning at the correct speed for the amount of distance the car is moving. As for the stutter in the animation I'd guess you rendered at one frame rate like 24fps and then converted the frame rate to 30 fps or something when exporting it as a movie file. This would cause some frames to be repeated and make the motion "jaggy" or more correctly called "stuttered". Usually when peopel talk about jaggy's they are referring to Anti Aliasing problems.

Sorry for my incorrect english terms, but isnt it so that i just render out like 350 frames for this particular animation, and those 350 will be fitted in according to your framerate?
I just render out 350 frames and import those into a. after effects project. I get the impression after effects just puts each rendered frame on a single frame in the timeline, like.
say at 30fps it is 30/350 = 11.6 seconds and
at 24 fps it is 24/350 it is 14.6 seconds, so that just the animation runs slower or quicker. I cant find any framerate settings in maya aswell so. Ill look into the anti alias for the door. And for the wheels, do you have any suggestions? i tried to guess the speed bij increasing and decreasing the degree of rotation over the time it moved. Is there a more accurate way to simulate this?

greetings, and thanks for your reply!

You can choose the framerate by clicking on the animation prefs next to the autokeyframe button (has a skeleton key for an icon) in the lower right hand par to f the GUI.

There is another way in AE that you could accidentally misinterpret the frame rate and cause stuttering. You could drop a clip that is one framerate into a comp in AE that is a different framerate. Unlike importing clips into AE this will not place one frame of animation per one frame of the comp. So if your clip is 30 fps and your comp is 24 fps then you are forcing the the comp to drop frames unless you are using frame blending or field rendering.

As for turning wheels there are scripts and expressions for it (look in the mel scripts section on this site) but visually it's not that hard to see that the wheels are slipping when keyframing by hand.

BTW if you look at your rendered animation in fcheck does it look smooth?

[snuurtje]

im not sure, i rendered a bit again, but my computer cant display the animation at the correct framerate in fcheck.

edit:
This is weird, i just checked my graph editor, and my curvers have changed or something.. :-S

The curves arent smooth anymore but have a sharper edge in them. How can this happen, im sure they were smooth when i first created them . How can i fix this?

That's just a display issue I have seen in maya occasionally.. resize the window and it'll probably clear it up.

when you load your frames into fcheck you probably need to enter a shrink value so that you are not trying to display for HD resolution
