As you’ve seen in previous posts, I’m a fan of
latestdeals.co.uk. I browse it daily and have bought some incredible deals from it. When I spotted a DJI OSMO Action 4 for £159, originally priced at £279 when first released, I was interested.
I watched a few YouTube videos titled “Is the OSMO Action 4 Still Worth Buying in 2025?” The consensus was yes; it remained a well-featured Action Cam in 2025, now available at very attractive prices. Although tempted, I didn’t buy it immediately. On Saturday morning, I checked again and saw it was still on offer on Amazon, with a note saying “Order within 2 hours for delivery TODAY.” Skeptically, I thought, “Yeah right, no way.”
I decided to order and received a confirmation from Amazon stating delivery by 10 p.m. It actually arrived at 7:30 p.m.—just 9 hours and 55 minutes after ordering!
I verified that it worked but didn’t look at it again until Monday. For events at my local church, where I run the tech and livestream the service on Sundays, I sometimes use a GoPro mounted on top of the main camera to provide a second camera angle in OBS. I thought the OSMO 4 would be ideal for this. Checking the forums, I found that this setup was possible, although one poster mentioned they had failed to get it working.
Being a tech guy, I knew what I was doing, right? I used a USB-C to HDMI connector from the OSMO Action 4 to a long HDMI cable, then into an HDMI to USB3 connector, and finally into a USB3 port on a micro PC. It should have shown up in OBS—just as it does for the main camera. Wrong, it didn’t work!
I tried swapping connectors and cables, but still nothing. So, it was back to the forums. There were no immediate answers, but I found a reply from a DJI tech advisor suggesting using a USB-C to USB-A connector into the PC. I tried it, and the camera screen displayed “Use Webcam.” Immediately, it appeared as a device in OBS. Selecting it, I had a perfect video image ready to broadcast.
As I said.....keep it simple stupid!
