Hiho!
Two good news today!
Tutorial 2 "Projects Guidelines & Video Mixer Transparency Magic" is released as of now. The guidelines will help you organise correctly your project tracks for the GiraFX lib context. It will also introduces you to the central mode of operation of the GirafX video mixer and how video FX chains can gradually build transparency information for it. Enjoy!
The second one! During the process of creating tutorial 2, I found a long sought solution for making the "chromakey YUV" preset a mask (much simpler to use) instead of a pre-mixer. As a reminder, chromakey in YUV mode gives much better results. This solution is now the new preset called "girafx:mask/chromakey (YUV)" that makes, of course, its previous pre-mixer version obsolete. The library "rpl" file has been updated accordingly as v1.01 but since you currently have v1.0 just download the v1.01 update RPL and import it like you did for v1.0.
cioa!
