• The RECORD button lights white

3.11.1 Recording Capability

mini-extreme ISOsupports recording one fixed Program output (PGM) and up to three input sources simultaneously.

Selecting PVW (Preview) or AUX outputs as the recording source is not supported.

ISO recording allows separate recording of the PGM output and input sources. Each source generates an independent recording file.

The factory default setting enables one PGM recording channel:

• Resolution: 3840 × 2160@60
• Bitrate: 8 Mbps

To record additional input sources, adjust the recording resolution and bitrate for PGM and each input source in OUTPUT > Record > Configuration.

The recording resolution follows the input source resolution. If the input source is 1080p, the recorded video will also be 1080p. The device does not upscale the video to a higher resolution.

📢  Notes
When recording multiple input sources, lower the PGM output resolution to 2K@60 to select up to 3 input sources for recording.

Higher bitrates provide better recording quality but require more storage space.

📢  Important
No supported mini model allows users to configure the PGM and UVC output source independently.

3.11.2 Start Recording
