Time & retiming
Shifting, holding, retiming with flow, and what a retime does to everything downstream of it.
The time family
| Node | Does |
|---|---|
| TimeShift | Offsets the whole branch in time |
| HoldFrame | Freezes one frame |
| Retime | Speed change: nearest, blended, or flow-warped |
| TimeEcho | Accumulates previous frames — trails |
| MotionBlur | Blurs along motion |
| MotionVectors / VectorBlur | Computes and consumes motion |
Retiming
FLOW mode solves optical flow between the frames it lands between and warps them together. It is the good-looking option and the expensive one; blend crossfades and nearest steps. Judge a flow retime on the moving edges — that is where a flow solve fails first.
