Should Your Video Podcast Be Recorded Directly to Camera or Via a Video Switcher?
The 30-Minute Recording Limit: Why Prosumer Cameras Weren't Built for Podcasting
Here's a dirty secret most "multi-camera" studios won't tell you up front: their fancy Sony A7, Canon R6, or Panasonic GH cameras can't actually record a full podcast episode in one take.
The problem: Most mirrorless cameras have a 29-minute 59-second recording limit baked into the firmware.
Yes, you read that right. Your 45-minute podcast interview will stop recording at the 29:59 mark on all three cameras, right in the middle of your guest's best story.
Why This Limit Exists
It's not a technical limitation. It's a tax dodge.
In the European Union, video cameras and still cameras are taxed differently. Video cameras face higher import duties (around 12-14%) compared to still cameras (typically 2-5%). To qualify as a "still camera" for tax purposes, manufacturers programmed their cameras to stop recording around 30 minutes.
This made sense for photographers who occasionally shoot short video clips. It makes zero sense for a podcast recording where episodes regularly run 45-90 minutes.
Some manufacturers have removed this limit in recent years:
Sony removed it on newer models (A7 IV, A7S III, FX3)
Canon removed it on the R5 C and R6 Mark II (but not the original R6). These are very expensive cameras
Panasonic removed it on the S5 II and GH7
But most studios are still using older models with the limit because they're not about to spend £2,000-3,000 per camera to upgrade when "it mostly works."
What Happens When You Hit the Limit
Scenario 1: The cameras just stop
You're 30 minutes into a 60-minute recording. All three cameras hit 29:59 and stop recording simultaneously. The audio keeps going (separate recorder), but now you have:
30 minutes of synced video
30 minutes of audio-only content (no video)
Your editor either:
Cuts the episode at 30 minutes (wasting half your content)
Continues with a static image or the audio waveform for the last 30 minutes (looks terrible)
Records the second half as a "Part 2" which splits your audience
Scenario 2: Someone hits record again (creating more sync problems)
Smart studios train their operators to quickly press record again when the cameras stop. This works, but creates new problems:
Camera 1 starts recording again at 30:02
Camera 2 starts at 30:04 (operator was slower)
Camera 3 starts at 30:07 (operator had to navigate a menu first)
Now you have:
First 30 minutes: synced properly
Next 30 minutes: three separate files with different start times that need manual syncing (again)
2-7 seconds of missing footage during the gap
Your editor adds another 20 minutes of work re-syncing the second half of the episode.
Scenario 3: The operator doesn't notice
The cameras stop at 29:59, but your audio keeps recording. Nobody notices until you're 10 minutes past the cutoff because everyone's focused on the conversation, not the recording indicators.
You've just lost 10 minutes of video entirely. Audio-only podcast episode it is, then.
The Overheating Problem (It Gets Worse)
Even cameras without recording limits often have thermal issues during long recordings. Consumer and prosumer mirrorless cameras weren't designed for continuous 60-90 minute operation.
What happens:
Camera overheats after 40-50 minutes of 4K recording
Recording stops automatically with an overheat warning
Camera needs 10-15 minutes to cool down before it can record again
No matter which brand you use, try to buy cameras without any kind of recording time limit (check the specs on the B&H item page) The Podcast Consultant (https://thepodcastconsultant.com/blog/podcast-cameras).
Professional cinema cameras (like the Blackmagic Pocket Cinema Camera 6K we use) don't have these limits because they're built for continuous operation with better heat management.
Why Studios Still Use Prosumer Cameras
Simple: cost and availability.
A Sony A7 III costs £1,500 used. It takes beautiful photos and "decent" video. Many studios already owned them for photography work, so adding them to a podcast setup felt like a free upgrade.
A Blackmagic Pocket Cinema Camera 6K costs £1,900 new and doesn't take still photos. It's purpose-built for video production, which means unlimited recording, better colour science, and professional codecs — but it's a dedicated investment.
Most studios choose the prosumer route and just... deal with the limitations. They restart cameras every 30 minutes, accept the sync headaches, and hope guests don't notice the interruptions.
At Podcast Studio Glasgow, we don't do "deal with it." Our Blackmagic cameras record continuously for as long as needed — 45 minutes, 90 minutes, 3 hours — with no recording limits, no overheating, and no interruptions. Everything stays synced through the Atem Mini Extreme ISO, so there's never a gap in coverage or a sync problem to fix in post.
Your recording doesn't stop at 29:59. Neither should your cameras.
You need to trust us on this; we’ve worked with content recorded in other podcast studios, where the video is captured natively on the cameras. We’ve been sent Google Drive links to folders full of sub-30-minute video clips from 3 cameras, and then had to piece everything together in post. Now, we know what we’re doing, but even we found this to be a tiresome headache. How clients with little to no production experience handle it, we’ve no idea.
So, before you book that podcast studio recording session, check out the kit they use. And if they don’t list it, contact them and ask. You’re looking for a live video switcher, ideally one that also records video ISOs. If they don’t offer this, please look elsewhere. It’ll save you hours in post-production time.
