Does Mercury Transmit send super-blacks?
Premiere’s built-in monitors and its scopes ignore blacker-than-black blacks (aka superblacks), or 4-63 values in 10bit SDI terms.
But does it process and send them out via Mercury Transmit (specifically with Blackmagic SDI cards and boxes)? -

Don’t know the answer but isn’t it Super Whites and Sub Black’s.

Sh!t. You’re right, of course. 🙂

the YUV scopes use legal range. all the other scopes are full range. premiere itself uses full range.
with certain hardware boxes, it can goes from 100 nits to 1,000 nits.

Thanks for the reply, Chris, but none of it answers my question. ☺
Indeed, in the scopes you don’t see sub-blacks. And with the hardware boxes & cards, I’m not talking about HDR or nits, but about Rec.709 sub-blacks bit values.
Anyone who uses Premiere with a hardware box and knows what a SMPTE PLUGE is should be immediately able to answer.. -
as i said, full range is 0-255 which is all values including sub blacks.(below 16) and superbrights(above 235) that’s how premiere works, both in its engine and mercury transmit. however, mercury transmit’s color primaries are hard coded to rec. 709.
