ATEM SDI Comparison
If your church is transitioning from HDMI to SDI for more reliable camera connections and longer cable runs, Blackmagic Design’s ATEM SDI switchers offer a simple, affordable, and volunteer-friendly upgrade path. SDI cables lock into place, run much farther, and reduce signal dropouts during worship — making them ideal for church livestream setups.
This guide compares the three main ATEM SDI models so you can choose the right one for your church: ATEM SDI, ATEM SDI Pro ISO, and ATEM SDI Extreme ISO.

ATEM SDI
The ATEM SDI is the entry-level model in the SDI lineup — simple, compact, and perfect for smaller churches switching to SDI for cleaner runs and more stable connections.
Key Features
- 4 standards-converted 3G-SDI inputs
- 2 SDI outputs for program/aux routing
- USB-C webcam output (works with Zoom, OBS, ProPresenter, etc.)
- Built-in Fairlight audio mixer with EQ and dynamics
- Picture-in-picture, chroma key, and basic transitions
- Compact desktop design with integrated control panel
Best For
Churches using 1–3 SDI cameras that want a reliable, plug-and-play switcher without built-in streaming or ISO recording. Ideal for simple livestreaming setups where you handle streaming through software like OBS or ProPresenter on a computer.
ATEM SDI Pro ISO
The ATEM SDI Pro ISO builds on the base model by adding built-in streaming and complete ISO recording — a major upgrade for churches storing weekly services, editing later, or improving post-production workflows.
Key Features
- 4 standards-converted 3G-SDI inputs
- Built-in hardware streaming directly to platforms like YouTube or Facebook
- ISO recording of all 4 inputs plus program to a USB-C drive
- USB-C webcam output for software-based streaming if desired
- 2 SDI outputs for program and aux feeds
- Multiview output with camera previews, audio meters, and status information
Best For
Small to mid-sized churches using up to four SDI cameras who want built-in streaming and easy multi-camera recording. Great for volunteer-run teams who want a “press go and stream” workflow without needing a separate streaming PC.
ATEM SDI Extreme ISO
The ATEM SDI Extreme ISO is the most capable desktop switcher in the lineup. It expands camera inputs, adds more outputs, and includes advanced features like SuperSource — making it the best fit for multi-camera worship production.
Key Features
- 8 standards-converted 3G-SDI inputs for larger multi-camera setups
- 4 SDI outputs (including multiple aux outputs for custom routing)
- ISO recording of all 8 inputs plus the program feed (9 streams total)
- Two USB-C ports (for recording and webcam output at the same time)
- Built-in hardware streaming for direct-to-platform livestreaming
- Larger Multiview layout with up to 16 views
- SuperSource for multi-box layouts (lyrics, scripture, sermon notes, and camera shots together)
Best For
Growing churches running 4–8 SDI cameras, producing dynamic worship services, or needing separate SDI outputs for screens, overflow rooms, or a dedicated recording feed. Ideal for churches wanting broadcast-style flexibility in a desktop switcher.
