Camera cue in Qlab4

[Matt Davidson]

Hey all. Having trouble getting a black magic web presenter working with Qlab4. Qlab see's the black magic device in the camera patch and I can make a cue with it outputting to my surface without issue. It plays and I can see the green arrow next to it indicating it's live but all I have is a black screen. Other video cues work fine going to this surface. Signal is locked and fine going into the web presenter and the video input does work in Skype fine. Also I closed skype and restarted the computer incase there was some conflict going on there but that didn't fix anything. I tried different outputs from the camera like 1080i and 1080p. I saw a little about NTSC and Pal formats.. not sure I see that as a setting from the blackmagic presenter but would that be through the camera itself?

I've had Blackmagic WebPresenter and QLab4 working fine. I could test the latest version later in the week when I get time.

If you wouldn't mind checking Jon that would be great. We were fine for the event but now I'm just trying to figure out why it wasn't working. It seemed like I didn't have as many options to edit internal settings in Qlab. I remember in Qlab3 having frame rates and stuff that I was able to match up to the camera input and I couldn't find anything like that here.

I forgot to mention that it was a 2018 Macbook Pro and was going through an anker USB C adapter hub.

I should get a chance on Thursday, if I can locate a camera to plug into the webpresenter.

One of the advertised advantages of the webpresenter over other options is that you shouldn't need to match resolution/framerate, as it has a convertor built in. If it works in Skype but not QLab I'd suspect an issue in QLab receiving signal rather than the device not working. We have the screen and switch panel on ours, which is handy for error finding, as well as checking that the device has signal (and is framed) before you take it live.
