might help as intro

What I do is set some key values, first frame 0 for first frame and last frame number for last frame you want duration wise.
(set AE to time display mode to frame number)
Say your clip has 500 frames, first frame is 0 and last is 499
Then say from frame 300 to 400, you want frame 200 to 300 (100 frames in 100 frames is 100% speed), at 200 you set KF (keyframe) to 300 and at 300 you set 400.
Then you set the timeline view to graph editor, and you play with it visually – making curves, just making sure a curve does not go over the next keyframe in height as you would then go backward for a bit

It was sent over from Premier to what? After Effects

First, look at your movie after the 115-120% speed up – is it speed up or slow down?
Is there any frame blending in source movie caused by that (also you don’t want to skip frames)
It’s better to do all that in Twixtor

Second animated speed is cumulative, you might want to use Frame Number animation to have sections with 100% speed where you want it.

Hi Emily

Sales Support is supposed to have writen back to you

Actually time remapping technique (with Twixtor 100%) as you describes works for the basic Twixtor Speed % case in Premiere. Note Speed/Duration does not work as it duplicates frames.

Thanks for the example

Here’s a few ideas, and screenshot below:

1) It helps to set Global Color Reference Frame(s) – when levels change so dramatically
2) Because it changes so much from frame to frame, you probably need a wider time window
3) That said, the Timelapse plugin appears to have issues with the deep blue sky with flashing clouds… seems to reveal some compression block semi-related artifacts. That’s why I did an alternative setup to compare using the HiSpeed plugin. Note I use the Refine mode – the trick is to look at frames where some object appear and disappear with Refine Visualize checked and set the Refine Threshold to as high as possible so Red still covers these objects. The threshold will sort of create a max amount of deviation from original.
4)It’s also possible to combine the two techniques (and use smaller time window for each pass). As a simple example of that, using the setup I added here, if you set the time window to 0 in the Time Lapse one, you can turn on and off to see the pre-deflicker effect Global Color Correction has.

Your results look pretty good so far.

You can play with Motion Sensitivity if you see edge artifacts. It effectively limits the amount of motion a pixel can have.
