Please note that a newer version of Time Machine is available on Reactor.
Retiming has never been this much fun in Fusion!
A quick rundown of the modes:
Warp: scrubs inside the Source Start to Source End range using the Time Warp slider.
Remap: maps Source Start-End to Target Start-End.
Delta: steps through a range in user definable steps. *NEW in 1.2!*
Lock Start: locks Source Start to Target Start frame, and you can use Speed/Step to go from there.
Lock End: locks Source End to Target End frame, and you can use Speed/Step to go from there.
Random: random frames from within the Source range.
Hold: holds a frame.
Skip: skips frames, so a setting of 2 starting from 1 does 111444777...
Offset: offsets your source range forward or backward.
Trigger: repeatedly runs through your frames, based on thresholds. *NEW in 1.4!*
XSheet: retime your source frames using an exposure sheet! *NEW in 1.3!* with a mini scripting engine! *NEW in 1.5!*
Switch: easily switch to user definable starting points. *NEW in 1.6!* (requires Fusion 7.7 or later)
Before/After Time defines the behaviour before or after the Target Range. You can also force a Target Range in modes that don't require it, like Random or Offset.
Now that it's a Modifier Fuse you can use it on a TimeStretcher, or a Time3D, or even (in Fusion 7) any other parameter in Fusion.
