In Flow Nodes there are two 2D visual types, video and graphic. To edit a video you first need to sample a video frame into a graphic, this can be done with the Sample node. Once you got the video frame, you can apply any graphic effect to it.

If you want to edit every frame in the video, a Video Edit node is required. It will loop through every frame in the video and apply the edit you specify. This map node takes two video inputs, the source and destination. Destination can be an empty video state node.

To get the video frame count, use the metadata node
