I'm confused! I'm using Video Pro X (v15.0.5.211) on a PC running Windows 10 and with a i7-7700 CPU and Geforce 1070 and can't set keyframes for quite a few effects (like Brightness/Contrast !!!). Now I'm a) wondering why and b) if somebody compiled a list telling people like me, which effects can and which can't be animated with keyframes.
