Using Panasonic HS400 switch connected to laptop. connectivity is good, bringing in Tiff with Alpha and I am having difficulties keying using Alpha.
Manual says to bring image into fmem1 and alpha into fmem2 which I have done. I think I am 95% there but still not quite right. Looks like I am doing a luma key on the fmem1 instead of using alpha to key.
I am pretty sure it is a basic operator error but I cant seem to get it right. Any advice would be appreciated.
I actually avoided that approach, I have tried that in the past with other switchers, and have never been happy with the keyer. My current idea is to use a Blackmagic card with dual outputs (key and fill) into the 450. The main problem being that it takes up 2 valuable spigots on the switcher, so I have to invest in an extra input card for around $2k.
