VS preview error with smdegrain refine motion, block & overlap size, and color format
#4
Hybrid_dev_2026.10.04-204526 fixed the issue mentioned above.

There's another thing about thSCD1, by design Hybrid will adjust the value of thSCD1 according to the fixed block size I choose. and I think there are some bugs during adjusting thSCD1.

case 1: choose block size 4, and thSCD1 will be set to 100, and 8->400 & 16->1600, now dial back to block size 8 or 4, thSCD1 won't dial back to 400/100, it stay at 1600.

case 2. Hybrid do not adjust thSCD1 if block size is 32 or above. In this case thSCD1 might be 0 or any value previously adjusted and left in the field of thSCD1. I don't know what value thSCD1 should be when block size >=32, but if the value is 0, the output video look like that it's never filtered by smdegrain, all noise are still there.
