Operating system: Windows 10  
Slicer version: 4.11.20200930

I want to use the 3D Slicer version 4.11.20200930 and the Sequences Extension and Module to record a sequence. The sequence is a video captured with an IntelRealSense camera that is sent to 3D Slicer through Plus Toolkit. I can acquire the images either in black and white (BW) or in RGB. If I do the first option, the corresponding node in 3D Slicer is a vtkMRMLScalarVolumeNode and I can record and save it without any problem. However, if I do acquire the images in RGB, the corresponding node in 3D Slicer is a vtkMRMLVectorVolumeNode. For some reason, it is not recognized as a Proxy Node in the Sequences module. As a result, I cannot record the sequence nor save it.

I attempted to do the same with the 4.10.2 Slicer version and I could record both types of sequences (with the BW and the RGB images) without problems. So, I was wondering if anything has been modified in this new version regarding the vtkMRMLVectorVolumeNodes.

Thank you.
