Settings reference

Open settings with Cmd/Ctrl+,. Changes are saved immediately. Use Reset to defaults in the lower left to restore the defaults. On the Account tab, Sign out appears there instead.

General

This tab is split into two sections: Appearance and General.

Theme	System / Light / Dark	System	UI color scheme. System follows the OS theme.
Language	System / English / 日本語	System	UI language. System resolves from the OS locale.
Date & time format	Standard, with seconds / Standard, no seconds / System regional	Standard, with seconds	Selects the date and time display format used throughout the app.

FFmpeg

Set the location of ffmpeg, which is used for MP4 export and Quick Play.

Setting	Type / values	Default	Description
ffmpeg	Path string	Empty (auto-detect)	When empty, SeqLens looks for an automatically downloaded binary or ffmpeg available on PATH.

If FFmpeg is not found, Run setup wizard appears at the top of the tab. Path changes may take effect after restarting SeqLens.

Server

The HTTP API server lets tools on the same machine, or on networks you allow, read SeqLens information. While the server is running, the port, allowed IPs, and token-related settings cannot be changed.

The HTTP API server heading includes an Experimental badge. Endpoints, payload shapes, and behavior may change in future releases without notice.

Setting	Type / values	Default	Description
Address	Host display + port (1-65535) + API docs + switch	OFF / 5397	Starts or stops the server. API docs can be opened only while the server is running.
Allowed IPs	Newline-separated text area	127.0.0.1 ::1	IP addresses allowed to connect. Adding non-loopback addresses exposes the server externally, and an orange warning appears below when authentication is off.
Require token	Switch	OFF	Generates a token the first time it is turned on, and requires the Authorization: Bearer <token> header on API requests.
Token	Read-only text + Copy / Regenerate	Empty	Shown only when Require token is ON. Regenerate can be used only while the server is stopped.
