I'm using the Blackmagic Design ATEM Mini for the capture to HP Laptop. It's the clean HDMI from the 300s that is my problem.

Thanks for replying. The 300S is fine if you are recording. I need live HDMI without the settings ribbons. (Clean HDMI) Are you doing that?

I would truly love to use my Nikon D300s for live video but can't get the settings ribbon off the HDMI output. Substantial research has yielded nothing. Y'all are my last hope. HELP!

I'm using a D750 for the same application. Clean HDMI ok 1080p ok AF-F ok. Used camera should be in the same price range. Power: I use the attached battery pack and have yet to drain the pack with 1.5 hrs operation, meaning the internal battery never got touched.. A/C is an available option with accessories($$). I also got the EP-5B connector and the Case Relay from Tether Tools which lets the camera feed off a USB AC or Battery pack. That should run for many hours, though I haven't used it yet beyond initial testing.

Good Luck.

Thanks, I'll give it a try.

Is there a teleconverter that will work with the internal camera focus motor on my d750? Thanks.
