Use an NDI feed as a row's video/audio source. Pulsar finds NDI sources on your machine and across the network; pick one by hand or auto-bind by name.
How to open it
Set the row's type to NDI.
Click the row's source tag box — the wide button showing the current NDI source name (or
Auto-selecting...).The Row X Stream Settings window opens.
Stop the row's output(s) before you change the source — the tag box is locked while a row is streaming.
Pick a feed manually
Open the settings window and leave Selection Mode on Manual select.
Wait for the list to populate, then pick your feed:
Local Sources (monitor icon) are on this machine.
Network Sources (globe icon) are on other machines.
If your feed isn't listed, click Refresh Sources.
Click Apply.
The list appears after the first discovery scan, so it may be blank for a second when you open the window. It refreshes itself every 10 seconds.
Auto-select a feed by name
Auto mode binds to whichever source matches a search term and re-binds if that source drops and returns — handy for feeds that reconnect, like an Avid or playout system.
Open the settings window and set Selection Mode to Auto select.
Type a distinctive part of the name into Search Term (e.g.
AVID). Matching is case-insensitive.Pick a Match Mode: Contains (name includes your term) or Exact Match (name equals it).
Check the Auto-selected: readout shows the feed you expect, then click Apply.
If the readout stays on Auto-selecting..., nothing matches your term — broaden it or switch back to Manual select.
Fix missing or distorted audio
Some senders (Premiere Pro, NDI Player, NDI HX hardware) use compressed audio that needs decoding. If a feed has video but no audio, or distorted audio:
Open the settings window and tick Force audio decode (NDI HX compatible audio).
Click Apply, then restart the row's output.
If the audio is now too hot, drag Audio Level Pad into negative dB (e.g. -6 dB) and Apply again.
Leave Force audio decode off for sources that already have working audio (like the NDI Signal Generator). Only turn it on for NDI HX feeds with no sound.
Recover a feed that vanished
In Manual mode, click Refresh Sources.
If it's still missing, check that the NDI runtime is installed (open About → System Dependencies & Firewall), the sender is on the same subnet, and your firewall or VPN allows mDNS/Bonjour. A VPN kill-switch is a common culprit.
As a fallback, switch to Auto select with a broad Contains term so the row re-binds when the feed reappears.
A saved-but-offline feed stays at the top of the list under Saved (Not Currently Visible) — leave it selected and it reconnects on its own.
Controls you'll touch
Control | What it does |
Selection Mode | Manual select (pick from the live list) or Auto select (match by search term, re-binds when the source returns). |
Refresh Sources | Re-scans the network now (Manual mode). |
Search Term • Match Mode | The name to match and whether it must Contain or Exact Match the term (Auto mode). |
Force audio decode | Routes NDI audio through a decoder so compressed/NDI HX audio plays. Leave off otherwise. |
Audio Level Pad | Attenuates a hot incoming feed, 0 dB (no change) down to -40 dB. |
Tips & gotchas
NDI input arrives as 8-bit 4:2:2, so a 10-bit/HDR NDI source comes in down-converted. HDR is decided at your output encode, not here.
Audio Level Pad only cuts level below 0 dB — at 0 dB it does nothing.
A blank list right after opening is normal — give the first scan a moment.
