I've been looking for the right camera for our mobile podcasting setup ever since we started recording video podcasts away from our studio in 2012. When we first started Still Untitled, we used a GoPro HeroHD 2 to record the show. Over the years, we've upgraded those GoPros to newer models, but have remained pretty dissatisfied with the cameras--they just aren't meant to be used for long videos with lots of talking.
The action cameras I've tested have a hard time maintaining a consistent clock over long videos, which isn't a problem when you're recording a ride down a mountainside or your first time skydiving, but when you need to sync separate audio and video tracks, it's a huge pain in the ass that involves stretching the duration on either the audio or the video. Most action cams also lack viewfinders, so it's difficult to reliably frame your shot, and all this is compounded by the fact that action cameras simply aren't designed for long shoots. The camera have overheated over 40 minutes of runtime, which causes lost or corrupted video. It isn't a great experience.
We've tested pro cameras for podcast use before too, including the Panasonic cameras we use in the studio and the Sony PXW-X70 that Joey had on loan from B&H in January. Our aging Panasonics are tied to the proprietary P2 storage cards, which require a special (and very expensive) P2 deck to grab footage from. The Sony camera produced great video and integrated easily into my Premiere Pro-based workflow, but it is much more expensive than I was looking for and is frankly overkill for long, static shots.
On paper, inexpensive point and shoot cameras seem like the perfect middle ground between inexpensive action cameras and fixed lens prosumer models. We've used Norm's Sony RX100 Mk III for the last half dozen or so episodes of Still Untitled with reasonably good results. However, it's not an ideal solution either. While it's capable of maintaining a constant clock (making A/V sync easy), most point and shoots lack line-level audio inputs and they are universally limited to 30 minute maximum record times, either due to sensor overheating issues (rare) or strange European tariffs (common).
Enter the Zoom Q8. The Zoom Q8 was designed for exactly the situation we shoot Still Untitled in every week, longer fixed shots where audio is really important. Zoom specifically calls out podcasters, YouTubers and folks who want to record live music from the audience as potential users of this camera. While I can't speak to the latter, the two former use cases are spot on. I've used the Q8 to record three episodes of Still Untitled, and the results are exactly what I was looking for in this type of camera.
