IsoVolume on RGB video frames sequence volume

If i load a bunch of video frame jpeg into paraview, i cant use IsoVolume, why is that. Isnt each voxel just a 3 dimentional number e.g. RGB not scalar, can I not carve out a new IsoVolume based on some threshold value of Red or Green or whatnot, perhaps a union of Green and Blue scalars of the RGB triplet,.

Hello @Joe_Kozak,

You are mentioning paraview in your post. Maybe you should post this question on the paraview mailing list:
