Split Planes can't display chroma for clips in float properly.

python_jTEUl3XVAp python_ShSzU1tpGx python_6lULtoPjTO delowpass node is at a bit depth of 32 CR, JPBD nodes are at bit depth of 16

Check your monitor gamma

The easiest fix for this would to simply x 0.5 + if the input is YUV type float. The plugin will also throw an error for half precision formats because vapoursynth.Error: Text: Input clip must be 8..16 bit integer or 32 bit float, passed GrayH.

Actually for some reason the offset for equal representation in RGB is closer to 0.51.
