The video is lengthy, allow 2 minutes with fast forwarding, or 6 minutes with patience listening to my dialog about how it works and what to expect. This is updated, we bring in the footage, switch to Fusion, create the Robotbot_Segmentation node, followed by a ChannelBoolean to copy the red channel to the alpha, create a Saver.. then preview the result on the ChannelBoolean, before saving the sequence to disk.
Demonstrating the same thing is possible on Windows 10, using the Fusion Module for Resolve.
