Getting Started in Nuke

Using Nuke is a little overwhelming at first, but in this video, I cover getting a mask to disk, using the Rotobot_InstanceSegmentation node, followed by Shuffle and then Write. This has been calculated for a sequence in advance of this video, but one frame is calculated live. The mask is then brought back in via a Read node, the alpha channel is then inverted using an Invert Node, to allow a Multiply Node to change the colour of the background.

Getting Started with Nuke and Rotobot.

Using Resolve Fusion (free version) to save masks

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.

Using Fusion within Resolve to create a Saver node to write Rotobot’s Mask to disk, in an RGBA OpenEXR.

Demonstrating the same thing is possible on Windows 10, using the Fusion Module for Resolve.

Same again, but using a “Saver” node which is designed for the job, Slower Windows 10 machine.

DaVinci Resolve Support

A few colour grading folk on social media were curious if Rotobot OpenFX Plugin works out of the box on DaVinci Resolve. I did the same thing under Windows 10 earlier in the day, but here is a recording of me putting Rotobot through its paces on a MacBook Pro under macOS 10.12 using Resolve
