Time Warp compositing node
Warps time by slowing or speeding it up throughout the sequence.
This operation warps time by slowing or speeding it up throughout the sequence. This operation does not use any cache memory as long as 'Frame Round' is not set to 'Blend Frames'.
Tip | Try an index expression of $I + sin($I*5). |
Parameters
Warp Method | Allows you to control the warping using either an expression or a CHOP channel. |
Index | The expression to control the amount of warping. Try: $I + sin($I*5) |
CHOP | If you've set the Warp Method to CHOP, you should specify the CHOP path here. |
Frame Round | Rounds to the: Nearest, Previous, or Next Frame. If you select Blend Frame, it will perform the necessary temporal aliasing to provide a smooth result. |
