How I can render smooth animation ? Big render Problem.

Hi Guy's

I have a render problem. When I used ai files with position always video files flickering. 

Sample video:

Looking ae preview look perfect but after render gonna mad. 

I rendered h.264 30 fps

How I can fixed this and rendered smooth animation. 

Thanks.

Are you talking about the judder that occurs on the black lines when the rooster moves in from the right side of the screen? If so, either increase the frame rate to 60fps or make the move slower.

İ tryed and fixed. Thank you.

Do a search on this forum on "juddering scrolling credits" and similar wording along those lines. Rick Gerrad has explained this a million times. The basic gist is that the motion timing you chose unfortunately coincides with fractional frames, so the motion gets quantized a lot and items appear to jump between frames. making things slower, changing the shutter phase and duration, applying tons of synthetic motion blur or simply tweaking the keyframe timing to be more favorable can all help to mitigate the issue, if not fully remove it.

There is no motion blur, but your eyes expect it so the high contrast edges are harder to look at.

There is no easing in the move, but your brain expects it so the movement looks odd.

There are critical speeds based on movement and frame rates that cause a stroboscopic effect that must be avoided. The effect is seen often when you see the wheels appearing to move backward or propellers look like they are moving very slow. Thad Jiudder or Stroboscopic effect is mathematical and the fix is changing the speed or hiding the problem with motion blur. Increasing or decreasing the frame rate only changes the math and higher frame rates have a wider range of different speeds that will be hard to look at or look odd, but changing the frame rate will only solve one of the three problems with the animation before we start talking about the problems that can be caused by color and frame sampling you get with MPEG formats like h.264. You can get smooth looking motion easily at any frame rate above 12 fps if you understand the math and follow the rules. 

Understanding the technical limitations of the relationship between visual retention, frame rate, motion blur, and expectations is only part of the design process that a good animator goes through when creating an animation. The easiest way to learn how to make things work is to look at some movement that is pleasing to the eye and copy that.  Most of the earliest animators would film people doing all kinds of movement and then carefully study the frames so they could make cartoons look good. Disney animators were probably the best at that. Almost all had drawn animation is only 12 frames per second with each frame photographed twice. 

You have a good start. The black is not against a 100% white background, and the lines are not too thin. Just easing the movement to a stop and adding motion blur will probably go a long way to making the animation look better. Try looking at several other examples of graphics moving into the frame and see how they look to you. Just jacking up the frame rate to 60 fps is a real waste of time for a project like this.

Thank you.
