How to avoid Choppyness when moving a still image?
Hello everyone,
I am a beginner.I want to animate a still image with a straight movement (costant speed) from A to B (only “x” coordinate changes while “y” is the same for both the points)
Composition 4k 25 fps.
The result I get is too much choppy…while I would like to get a fluid movement.
Any suggestions?

making your comp 29.97 fps will help a bit but animation is frames per second over time..so increase your time and it should be less choppy

Thanks a lot.
Can this one be a solution?
Let’s say I want a final video at 29,97 fps that lasts 6 seconds
I create a composition 59,94 fps lasting 6 seconds
Convert 59,94 fps to 29,97 fps getting a video lasting 12 seconds
Timestrech 50% getting a video at 29,97 fps lasting 6 seconds
It is a stupid thing???

sometimes that does fix some things..but i don’t think it will help because the final result will still be 29.97 But your math is correct. give it a shot i suppose. There is also easy ease..right click on the final keyframe and choose easy ease in and see if that makes it better.

although the speed wont be constant on ease in..it will speed up at the start and slow down at the end

This is commonly called “judder,” and it’s the result of your move being too fast for your frame rate. When the amount of change between one frame and the next is too great, we lose the illusion of smooth motion — not all moves are possible to execute smoothly.
Cinematographers carefully time their pans to avoid this in motion pictures; although adding motion blur sometimes helps, I think your best bet here is to slow down the move.

We run into this a lot. On my end shooting with RED, I would keyframe blur to tone it down a bit.
Now sometimes the judder is screen ripping from slow refresh rates on your displays.
Fun having to explain that to a client 😛

Thanks a lot for the suggestions!
At least now I know the name of my enemy “JUDDER“
