Bo,

Your latest release is really good,  congratulations!   Here is an idea for future releases.   It is common to use tracking markers on the green screen so that filming can be done without a tripod and result in more realistic camera angles.  But the tracking markers have to be a different hue or tone from the green screen so the tracking software can see them.   The sugestion is for Cinegobs to have another tab for keying out the tracking maker color.  The tab would have a color picker and threshold controls to get rid  of the markers.   Currently,  I have to increase the threshold of the main greenscreen keyer to key out the markers too but this eats away parts of my foreground objects which are in shadow areas and eats away hair too.     I guess I could do two passes with cinegobs,  one to key out the main green screen and save it to PNG files and then bring in the PNG files into Cinegobs again for the second pass to key out the trackers and then do spill removal.  I haven't tried it yet and don't know if this would even work but it would be nice to do it all in a single pass anyway.  Just an interesting idea to think about.

Thankyou for this great work.  Up to now I have been filming greenscreen with the camera on tripod and bringing the actors into Blender and using Blender's camera to get the camera angles and closeups I want.  But now I am switching to hand held filming (with a home made camera stabilizer) with green screen with trackers to get much more realistic and better looking footage.  So this new addition to Cinegobs will be really great.
