Frame Loop
Updated: 9 Jan 2024
Dynamically Loop a number of frames.
Frame Loop
Method #
This node stores a number of frames over time and once activated loops the stored frame buffer.
There is no limit to the frame buffer, but you may need to keep an eye on VRAM usage to make sure you don’t overflow the buffer. If you are using this node to record more than a minutes worth of frames, you’re probably looking at the wrong solution to the problem.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount Changes the opacity of the new effect over the original image.
Blend Mode (RGB) Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha) Change how the generated effect blends with the parent image alpha.
Capturing Enabled Once a value < 0.5 is set, frames will being to loop.
Frame Buffer Size Number of frames that will be buffered and looped through.
Loop Mode Change how the looped frame is selected.
- Loop : The frames progress through the buffered frames in sequence, then jump back to the beginning of the buffer.
- Mirror : The frames progress through the buffered frames in sequence, then reverse back through the buffer before starting again.
- Loop Reversed : The frames progress backwards through the buffered frames in reverse sequence, then jump back to the beginning of the buffer.
- Mirror Reversed : The frames progress backwards through the buffered frames in reverse sequence, then reverse back through the buffer before starting again.
Capture Frame Skip Determines how many frames should be ignored between each frame captured: every nth frame is captured.
Playback Rate Control the speed at which the looped frames play back at. Lower values will slow down the playback speed, while higher values will increase it.
Toggle which of the RGBA channels are affected by the effect.
