time remapping is making my footage jumpy!
Hi guys. I’m working on a comp where I have a pre-rendered 360º animation of a school site. The idea is having the animation freezing at a certain frame, after that cuts to a still and comes back to animation again and starts where I left off. So, as I think any normal AE user would use I used Time remapping. When I output to a .avi, the result looks jumpy. Any ideas why? Thanks.

wild guess but maybe try easy ease keyframes to makes less jumpy keyframes. it helps alot with animation rotation too.

Are you suddenly freezing the footage, or slowing it down to a stop? If you drastically slow the motion, there may not be enough information to make it smooth, and the result will be jumpy. Is the render jumpy all over the whole footage, or just in the places you applied the time remapping?

is your pre-rendered footage in a format like mpeg, MP4, h.264 or another format that throws away keyframe animation? If so, you’ll need to convert it in another program to a video file format that After Effects can use.
You will always get weirdness with those file formats.

I have a sequence of 1000 .exr frames and a stop it suddenly to make the still comes in place. After the still has played its part, the sequence starts exactly where it’s stopped previously. That’s what I’m doing.

instead of using time remappping, just take your sequence up to the point of the freeze and put that on one layer. Then take the frozen frame, make it as long as you need it, and put it on another layer that begins where the other stops, then make a third layer of the remainder of the footage and put it where you need it to start up again.
I’ve done this many times to freeze animations where I need them to freeze for adding bullet points of info about the subject I’m illustrating in my animations. An example of this is at https://www.roncoy.com/Demo.html in the top right video where the animation swings around and stops to allow the text to point to the relevant parts of the model.
You can also time remap the moving footage parts to gradually slow down and speed back up, without having to jack around with the timing as much as when the time remap has to deal with the entire piece of footage as a whole. What I mean is, it’s easier to work with time remap when you’re only dealing with a speed up or slow down, as opposed to both on the same piece of footage on the same layer… at least in my experience.

I just realized no one mentioned Frame Blending. Turn that on. It’s required by time remapping if you slow down or speed up by a huge ammount.
