Animated grid with images, unwanted jitter

Question

I not sure what im doing wrong cause Its really rare I get jitter. I have made an tall image that have pictures in a grid. I have then linked this image (with image grid on) to a null that I have animated. The only movement is a vertical where I start of the image revealing the lowest pictures in the grid. Then I go upp to the upper row of images of the grid. I addad a little ease out, ease in to it.

I tried to crank up the motion blur but that does not help. Sure I could go 50p instead of 25 but the rest of the project is in 25p. The problem is that the image jitters and it feels like the images I pulsing a little.

I think this I this is mabe due to subpixle movements. Perhaps I should use a script like for end crawls. But then I don't now how to keep the easy out easy in.

I tried to oversample the images 200% when I exported the sequence from after effect but with no extra gains.

Ok, I should kill the easy out and in and get the speed correct first. Atleast the speed graphs is not curved anymore. So should I change the speed from 300,345 to 300 and that 300times 25= 7500. So its cool unless you have decimals?

Hi there,

yes, take off the eases and you should see a straight line - denoting an even speed. Select both the key frames and you should see a bounding box around them. Drag this till the speed is an even increment of your frame rate. If you have trouble getting it exact you can double-click the keyframes or right-click to enter the keyframe velocity box where you can manually enter an outgoing and incoming speed for each kf. Once you have done this, add another of about 1 second before and after the first and las keyframes. Use the pen tool to do this. This will make sure that the value remains constant between these when you alease the first and last kfs. Then finally, ease the first and/or last keyframes. You may also consider the overall speed. It may just be too fast for the frame rate?

It did help some with the smooth credit scrolling on the paste bin. But there is still a little flicker left. Aslo now the animation is constant and I cant start stop the motion where I want. So there got to be a better solution.
