Animations are jittery?

[rego]

Hi
I am facing a particular problem in c* and wondering if there is any solution as i have tried everything i know of.
When animating a text roll and watching the rendered output in any editing systems the text has a gittery motion, almost like a strobe or a blur. The same text animation done inside any editing system gives a good result.
I have checked anti-aliasing and Supersampling but this makes no difference. I have also rendered in front mode, without using camera. Also tried with different options of field. Also tried a bit of blur…
By the way the same problem also occurs with images or graphics.
Any body with a solution? 🙄

Which were the steps you used with fields?

Because the right one is:

Set the field dominance in the composition settings (upper first if PAL – but if you’ll get DV render it should be lower first – I don’t know which one’s yours) and if you have more than one nested you should do the same for each one; then in the render dialog box set the field dominance to none (otherwise you’ll get a “half res” image).

Well I just checked my workspaces, the options you told me are the default ones and i have not changed them. i.e the field dominance of my comp is “upper first” and in my render “no Fields”. Actually also played the .mov on my computer and i can see the same jittery motion i was talking about on my progressive monitor. so i dont think its much of a viewing problem, i think combustion cannot handle something rolling across at a little fast speed. In fact just playing the animation directly in c* without rendering also gives a jitter. I think you should try to do a quick text roll and you will know exactly what my problem is, Thanks

I wouldn’t trust your pc (mac?) and definetely not Combustion to play back your animation at proper speed and without jittering. Take it to a genlocked system and play it.
Is the motion linear or not? If so that could cause problems…
I have done scrolling texts in combustion both with and without fields and have had no problems. So it can be done.
I know that certain speeds and textsizes can be problematic but have been able to fix it by either adjusting speed and size or give the text a slight y-blur.

Cheers.

Moving text tends to strobe like a mother regardless, and gets worse depending on the type face used. Also, the faster it moves, the worse the strobing.

Motion Blur might help in cases, but unless the type stops moving, this tends to look bad.

I don’t know if this is what your issue is, but I have run into strobing text a ton, and the only tricks I can think of are to change the typeface, slow it down or have it move altogether differently.

Phew! finally someone agrees with me… 😛
O.k first of all i have tried all kinds of blurs and its not good enough.
The animation I am doing is just a title roll- the end credits at the end of a TV program( just that simple)
But c* just wont do it for me the easy way. My be the 30 sec duration is too less for the animation, but then the title motion in Discreet Edit does this roll perfectly.
Keyser_Soze suggested this but I cannot change the motion from linear, but as it is an end credit and has to be linear.
I cannot change the font either as that is the standard font the client wants.

No, I think you misunderstood me. The motion should be linear. If not you will definetely end up with unwanted artifacts.
If things work fine with discreet edit, why not go for that?
