Broadcast & recording

CastPad controls streaming and recording on the switcher itself, plus external HyperDecks and streaming encoders. The top bar’s ON (red) and REC (amber) indicators light up whenever any of these is live.

Note

You can add and try out the broadcast cards in Demo (mock) mode with no device connected — handy for laying out and previewing the controls beforehand.

ON AIR card (switcher streaming & recording)

On ATEM models with built-in streaming/recording, add the ON AIR card.

• Stream — tap to go live, press and hold to stop (so you can’t end a broadcast by accident).
• Record — tap to start, hold to stop. The card shows the elapsed time, NO DISK when there is no recordable disk, or the remaining recording time when a disk is available.
• A gear button opens options:
  • Streaming — platform, service name and server URL (auto-filled when you pick a platform), stream key, and quality.
  • Recording — filename, drives, and ISO per-input recording. Turning on Record all cameras automatically includes the individual ISO inputs.

Quality profile

The quality picker applies to both streaming and recording. Pick one of six profiles, or leave it on the device default:

• HyperDeck — High / Medium / Low (high-bitrate, for recording).
• Streaming — High / Medium / Low (lower-bitrate, for live).
• Device default (no change) — leaves the switcher’s own setting untouched.

When ISO recording is on, the button reads ISO REC.

HyperDeck card

Add a HyperDeck card and connect it by IP (CastPad talks to HyperDecks over the network).

• Full transport: record, play, pause, previous/next clip, and a shuttle / jog scrub strip.
• Tap to start recording, hold to stop.
• Choose the record slot (SD / SSD), set a filename prefix, and see clip length and remaining time.
• Connect several HyperDecks — each card is labelled by model and number.

HyperDeck options

The gear button opens extra controls:

• Recording filename — set a prefix, with an Add date · time toggle to stamp each file.
• Format — wipes the whole slot (every file is deleted; requires confirmation).
• Clip list — pick which clip to play, or reload the list.
• Rec settings — codec (H.264 / ProRes), video and audio input, timecode input, and the record trigger.

Streaming Encoder card

Add a Streaming Encoder card for Blackmagic Web Presenter / streaming encoders (connected by IP).

• Start the stream by tap, hold to stop.
• Set the platform, server, quality, video mode, and stream key.
• Connect by network scan, by IP, or as a mock device for testing.
• Live status and bitrate are shown on the card.

Top-bar indicators

Indicator	Lights when
🔴 ON	The switcher is streaming or any encoder card is live
🟠 REC	The switcher is recording or any HyperDeck card is recording

Caution

HyperDecks and encoders are only reflected in the top bar if you have added their card — the card is what connects CastPad to the device. Without a card, CastPad has no way to know the device is recording.
