Hi,

is it possible to use a USB-C to HDMI adapter to connect the OSMO action 3 to a Capture card/device like the Blackmagic ATEM mini?

Thanks.

the webcam is plug and plau uses the usb c to A cable, you may try and buy a cable if like, if others who own such a cable and has experience   will chime in.  good luck.

Hi, Quijano. Thanks for reaching out. Osmo Action 3 does not have an HDMI port and can only transfer data through a USB-C cable. The specific connection method and third-party device you wanted to use have not been tested by our engineers. Therefore, we cannot guarantee the result and performance. We hope you can get recommendations from your co-users with experience in such a setup. Should you have further concerns, please reach back here at DJI Forum. Thank you, and have a nice day!

Hi  Quijanom,for the USB-C to HDMI adapter in the market , they convert dp to hdmi.

For action3 , type-c does not ouput dp, only uvc usb camera,
So not possible to do the thing u mention.
