Well, they advertise it as having "RedCode 42".

I guess that means 42 MB/sec. and I hope it is for 24fps and not for the 120fps mode.

The "old" Scarlet was advertised as having RedCode 100 and I remember Jannard's posts that this is the datarate for the highest-speed, 120fps mode. Which then gave us 20 MB/sec. for the 24fps mode. These were the "old" specs.

Now, if the current "RedCode 42" means this datarate is for 24fps, then the datarate for 120fps should be ~ 210 MB/sec.

So the max datarate for Scarlet would be ~210 MB/sec.

But these are all speculations on my part.

Clarification, anyone?

Mister Jannard, RED?

Or after NAB?

BTW, Lossless 3K RAW at 120 fps should be ~ 500 MB/sec.

Has anyone looked at HDMI? I don't know what the limitations are, but my TV likes it.

HDMI is limited to 1920x1080, up to 60fps. Technologies that expand upon the TDMS digital link, such as displayport (and various forms of DVI) are capable of higher resolutions, but HDMI specifically is mainly built as a consumer interconnect to allow enforcement of digital rights management. Its impossible to field terminate, for making your own interconnects, the connector is not locking and easily falls out, limited signal strength over distance limitations would seem to be sufficient discouraging factors to consider using in a professional capacity (other than access to cheap local monitoring)

Thanks. Just a thought.

Some of this is info is dated. HDMI 1.3 can output "1600p75" (up to 30-bit/px; the native resolution of the 30" ACD). Not all products that have hdmi use hdcp (high-bandwith digital content protection?). And as for locking, go here.

I think that if you can work around it's limitations, then you can probably use it in a small studio-type of setting.
