Nodes
Preview
Look at a sequence or a mask without leaving the node editor.
Displays an image sequence or a mask sequence so you can check what a step produced.
Two inputs, Image Sequence and Mask Frames. Connecting one hides the other, so the
node always shows a single thing.
Using It
Wire it wherever you want to look. After a conversion to check the frames landed, after an AI Mask to check coverage, after a Lens Distortion to check the warp.
The node shows the folder it's reading and displays the current frame.
Handy as a quick sanity check before running an expensive step on something that turns out to be wrong.
