Each project carries its own settings, opened from the project's settings panel. They're organised into tabs - this article maps what lives where, so you know where to look when a behaviour needs changing.
The project's identity and housekeeping: Name, Creation date, Custom Metadata, and location.
How video is played and output, in three groups:
The video page is also home to Playback Media Quality, which controls whether originals or proxies are played (see Proxies and performance media).
Audio configuration for the project, including the sample rate. (This tab appears when advanced audio setup is enabled.)
Where the project's media lives and how it's managed - material drives and locations for copied, converted, and generated media (see Media management).
The Tasks page shows the project's background work - imports, exports, proxy generation, archives - with progress and a log (see Batch export and background tasks).
If a setting should follow the project (frame rate, media locations, playback quality), it's here. If it should follow you and your machine (appearance, layouts, shortcuts, hardware), it's in the application's Settings menu (see Application preferences).
