You can put these pretty far away from your subjects and try to light the scene again, $50, maybe get two or three, if you can, you can also use ring lights, but again, that could be pretty harsh depending on where you place those. I would recommend the Elgato key light airs. Those are great options. You can control brightness and color temperature, and you can put them just on a regular stand. And if you're looking for an advanced lighting option, I would recommend one of the Aputure 120 D lights or the Amor and 200 X with the Light Dome, the Light Dome 2, getting the larger version. We'll give you a lot of great soft light covering a larger area and if you could get two of those, so you can cover multiple guests from different, hat's really the best option for lighting your video podcast.
Then one of the most important aspects after lighting is video, how are you capturing the video of multiple in-person guests for this video podcast? You can actually use your iPhone and Riverside has a great feature called secondary camera where you can connect multiple devices in a Riverside recording and actually get all of those angles recorded.
As separate video tracks, we have a whole video explaining how to do that. You can check the link above. Maybe it's just one camera because you're recording with remote guests or you need multiple, the Sony ZV-E10 is a great option. You can actually get interchangeable lenses and it has great auto focus, which is a big deal when coming to video podcasts and you don't have someone monitoring all the cameras in the focus.
