Timewarp in Smoke - Speed Bump
on Aug 15, 2011 at 6:56:25 am


I’ve been trying to generate a speed bump in Smoke. I have a reference clip from FCP and I have to rebuild it in Smoke. What is the best way to do that?
If I have the clip in its original lenght, and match the in and out points with the ref clip, then insert it in the timeline, so it’s already sped up and the correct length, and then access the TW soft effect and start playing with the keyframes in the animation tab, I get totally messed up results… (and it doesn’t matter if I have LOCK BOTH or LOCK OFF selected, it still doesn’t work).

So how can I create the speed bump, and still have the same first and last frame like in the reference clip and also keep the same duration as the reference?

Hello Corinna,

By default, the Soft Timewarp only adds a keyframe to the first frame of the segment. To achieve what you want, you should:

1. Enable the Soft TW on the segment of your choice
>>> Default speed should be 100%

2. Enter in the Soft TW editor
3. Go to the last frame of the segment
4. Press the Set Key button
>>> A keyframe will be added on the Last frame

5. Change the speed in-between the two keyframes.

Hope this helps
