Hi, that's right regarding 'debug mode wax' it can be used to edit video clips and add special effects. I'm only just using it for the first time but have created some animated overlays that I'd like to use when streaming with OBS. Creating the effect has been ok as I already had the graphics to use for the transitions. However, OBS only has a plugin for including video into a scene and it doesn't have a chroma key feature so what I created has a green background which I'd like to be transparent. I understand a few formats do support an alpha channel such as RGBA with avi but I then need the rendering software I think to render just the alpha channel of the background clip out along with the effect layers.
