AURA's professional output is SDI, using Blackmagic DeckLink cards. It is what you use to deliver to a head-end.
Assigning the card
In the channel panel, under OUTPUTS, pick the device and the video format. Each channel uses its own output.
Available formats
Both frame-rate families are supported. Which ones you actually see depends on your card — AURA offers whatever it reports.
| Family | 50 Hz | 59.94 / 60 Hz |
|---|---|---|
| 4K UHD | 2160p 25 · 2160p 50 | 2160p 29.97 · 2160p 59.94 · 2160p 30 |
| Full HD | 1080i 50 · 1080p 25 · 1080p 50 | 1080i 59.94 · 1080p 29.97 · 1080p 59.94 · 1080p 60 |
| HD | 720p 50 | 720p 59.94 · 720p 60 |

Knowing it is working
At the bottom bar, next to the clock, you get the status. With a good signal you will see SDI ready in green and a stable cadence.
AURA watches the card continuously: if it stops responding for more than three seconds — cable pulled, card unplugged — it detects it and warns, instead of broadcasting into nothing.
If you see stutter
The cadence indicator in the bottom bar is the one to watch. It should sit exactly on the format's rate. If it drops, something is competing for the machine.
Usual causes, in order of frequency:
- Media on a saturated network drive
- An antivirus scanning the video folder in real time
- Subtitle transcription with the large model on a tight machine
- Another heavy application open on the same computer
