Main Review Window

The main window is organized around a video surface, timeline, transport controls, frame entry, loop status, and status bar.

Key surfaces:

• Current video header: shows the active file state.
• Video surface: displays decoded frames or the empty-state prompt.
• Timeline: supports live scrubbing and lands paused on release.
• Transport controls: previous frame, rewind, play/pause, fast forward, next frame, and full screen.
• Frame entry: jumps directly to a 1-based frame number.
• Status bar: shows playback state, frame, timecode, runtime/cache state, and pointer coordinates.

Playback And Stepping

• Space toggles play/pause.
• Left and Right step one frame while paused.
• Holding Left or Right repeats frame stepping.
• Rewind and fast-forward controls move by time on the shared transport.
• Pane-local controls in compare mode include single-frame and 100-frame navigation.

When audio output is active, playback uses the audio clock. Frame stepping and seek/jump operations remain decode/index based.

Video Info And Diagnostics

Use Help > Video Info or the video pane context menu to inspect FFmpeg-reported media metadata. Use File > Export Diagnostics when reporting a problem; diagnostics are local files and are intended to redact absolute paths where practical.

Full Screen

Use the full-screen button or the platform shortcut:

• Windows: F11 or Alt+Enter
• macOS: native full-screen window control or the app menu equivalent
