Pyxis front USB-C questions

PostThu May 09, 2024 11:23 am

How much information has been released about the front USB-C (aka the EVF port) on the new Pyxis camera?

I understand it provides a standard Display Port output feed, and obviously it is capable of handling at least some camera control signaling from the EVF. But how far does this go?

For instance, could I attach one of the USB powered "laptop companion" screens (many of them less than $100.00 these days) and use that as a large (and inexpensive) camera monitor? And how many control functions will camera monitor makers be able to incorporate in future USB-C based 5" and 7" units? Certainly screens in that size range will be low-power enough to be run directly off the port without requiring a separate power feed or battery. I would hope so anyway.

Also, can the port handle audio in and/or out? And if yes, then what sorts of additional accessories might this allow?

Of course the same questions apply to the Cine 12K.

I suspect this port will prove to be the most under appreciated feature of the new BM camera lineup, though ultimately it will lead to a lot of operator quality of life improvements down the road. How much smaller and lighter does an external monitor become when it doesn't need a battery mount or external power or video ports (or maybe just video out?)?

I don't see anyone asking these questions yet in the BM interviews I've seen, but seems like we ought to know.

I’m keen to know more about this too. Blackmagic have implied in interviews that there’s potential for other accessories to use the USB C ports on the ursa cine (so I guess also the pyxis), so I wouldn’t be surprised if they release a new video assist that works with it (though I suspect not a recorder, and not such high brightness, for power draw reasons).

Yes.

It’s display port. Among other things.

You can use an EVF to look at your desktop too.

That sounds crazy. So the EVF can be used with a computer as a Mirrored Desktop or as an External Desktop. I don't think I know of any other EVF that can do that. Wonder what more the EVF could do? Haha.

Presumably most EVF's with HDMI can display a desktop if they are fed a compatible res/framerate.

True. I guess since I have been SDI based for so long I didn't think about that. I've only had SDI based EVFs.

What’s on the wire? 10 bit, 8 bit, RGB, YUV, resolution?

Good Luck

I’ve used my current BMVA12G7 as a Mac Pro 2019 desktop secondary display via HDMI previously.

Think outside the box(camera).

Pun intended.

USB-C display port to HDMI adapter.
e.g.

Does display port carry audio in both directions?

The spec allows for it, but it isn't required and many manufacturers don't implement it.
