The Main Settings window is Pulsar's configuration hub — one scrolling panel where you set the default encoder format for new outputs, turn on Orbit and beta features, protect the rig with an operator PIN, and back up or restore your whole setup.
Click the red gear button in the top bar (tooltip: Main Settings). A separate Pulsar - Main Settings window opens. Click Close at the bottom when you're done.
If the rig is locked with a PIN, unlock it first — the gear appears once you're in. See Security, PIN & Lock.
Most sections are reached by scrolling the window.
These defaults apply to new SRT outputs. For per-output settings, see Encoding, Bitrate & Color and Outputs: SRT & NDI.
Changes save automatically. The options you see are filtered to what your encoders support, so 10-bit, 4:2:2/4:4:4, 2160p and the 10-bit/4K presets only appear if your hardware can do them. If a yellow warning box appears, your encoder doesn't support that combination — adjust it (you can still save, but it may not work).
Resolution is the only NDI default here — NDI doesn't use the H.264/H.265 encoder settings.
