Hold a chosen frame with optional rint, floor, ceil, or none rounding on the input frame value.

Frame Hold Advanced is a small utility group around Nuke’s FrameHold. It exposes an input frame control and a rounding mode so fractional frame numbers can be resolved before the hold is applied.

Use it when a freeze must track a driven or animated frame value and you need explicit control over how that value is quantized. Rounding choices are rint, floor, ceil, and none.

In the comp it behaves like a standard frame hold: the selected (and optionally rounded) input frame is held for the downstream stream. The group surface links the main controls for quick access in the properties panel.
