time remapping
Ok I’ve read the manual and I’ve looked at a couple to tutorials and I still can’t grasp time remapping. I want to slow some footage down then slowly increase it to full speed. Can anyone explain how I do this with time remapping? Thanks for the help. Ellen

I believe time remapping works by setting keyframes for points in your video footage and then moving those keyframes to either shorten (speed up) or lengthen (slow down) the length of that footage. You can place keyframes at the points in your video you want to manipulate and then change the keyframe types (bezier, linear, etc) to control the rate of change in speed to either linearly interpolate or ease in using easy ease keyframes. The best way to exercise full control over this is to open up the graph editor and visually inspect the velocity curves and make sure they are what you want.
I hope this makes sense and wish you best of luck.

When I try to do this, it initially slows the footage down to up to where I put the new key frame, but then as it regains speed after the new keyframe it ends up going faster and faster bypassing the speed of the original footage. What am I doing wrong?

You need to keep the same distance between keyframes as original to maintain original speed. So, if you move one keyframe in the middle towards the start to speed up the first part of the footage, you need to move the end keyframe with the middle keyframe to maintain the distance and speed. Otherwise, you are slowing down the end footage by increasing the distance (time) between the middle and end so there is less footage and more time and the footage slows down.
Best of luck

ohhhhh, it think i’m starting to get it now. thanks

allow be to add two tips to Mike’s good explanation.
Say the clip you want to remap is 30 seconds long in real time. Add some handles to it so it starts 5 seconds before you need it to and ends 5 seconds later.
Get to know the graph for time remapping. It will help you visualize the speed changes in terms of velocity, frames per second, and how the Beziers will help you smooth out the speed changes.bogiesan

you can also use the Timewarp filter which will allow you to set keyframes based on source frame or speed. personally i feel that being competent with curves in your graph editor is critical, and ultimately more flexible. but for a quick solution sometimes using the speed option of your timewarp filter is the right choice.
goodluck
