ATEM Mini Pro ISO HDMI Live Stream Switcher Bundle - Multicamera ISO

Our review of the ATEM Mini Pro ISO HDMI Live Streamer finds it best suited for small studios, educators, and content creators who need a compact, professional multicamera workflow with ISO recording. The single biggest reason to buy is its ability to record up to five separate H.264 streams (four inputs plus program) while live streaming, which simplifies post production and lets creators edit individual camera angles after the event.

Key Features

• ISO Recording: Records up to five separate H.264 video streams in real time so editors can re-edit multicamera shoots without guessing camera cuts.
• Multiple HDMI Inputs: Four standards-converted HDMI inputs accept cameras with embedded audio, enabling true multicamera switching without external converters.
• Built-in Audio Mixer: The 2-channel Fairlight audio mixer with EQ and dynamics makes it possible to balance mic and line sources without extra hardware.
• Multiview Output: Four camera multiview shows program, preview, media and status on one HDMI monitor to simplify live direction and monitoring.
• Streaming and Recording Outputs: Direct Ethernet streaming to services like YouTube Live and USB-C webcam out for simple streaming to a computer or direct recording to an external drive.

Who It's For

The ATEM Mini Pro ISO is ideal for educators, corporate presenters and small production teams who need reliable multicamera switching with native ISO recording. Its ease of setup, HDMI connectivity and simple controls make it a practical choice for livestreams where quick turnaround and post-event editing are priorities.

Less ideal users include large broadcast facilities that require SDI workflows or productions needing more than four live HDMI sources or advanced multi-track audio routing. Also, anyone needing integrated NDI or an abundance of separate balanced audio inputs should consider other solutions.
