Playback

Opening media

FrameLift plays video and images — MP4, MKV, AVI, MOV, WMV, FLV, WebM, M4V, MPG/MPEG, PNG, JPG, GIF, BMP, WebP, and anything else FFmpeg supports. You can open media in several ways:

• Drag and drop a file onto the window.
• Pass a path on the command line: FrameLift "C:\clips\demo.mkv" (see CLI usage).
• Open a network stream — http, https, and rtsp sources (and custom encrypted streams) via the "Open Network Stream…" action.
• Pick from history — the recently-played panel reopens a file at its saved position.

Audio & subtitle tracks

Files with multiple audio or subtitle tracks let you switch at runtime, and you can adjust subtitle delay on the fly. Default track selection can be steered by a preferred language in Settings; sidecar subtitle and audio files matching the media are auto-loaded when enabled.

Playlist

Opening a file automatically populates a playlist from its directory. The playlist supports:

• Recursive subdirectory scanning (with a configurable depth).
• Shuffle.
• Auto-reload when the directory changes on disk.
• Mixed video/image playlists, with a configurable slideshow auto-advance interval for images.

History & resume

Recently played files are kept in a searchable side panel along with their saved playback positions, so reopening a file resumes where you left off. How many entries to keep is configurable.

Dynamic audio normalization

An optional dynaudnorm-based normalization filter evens out loudness, with tunable parameters in Settings.

Overlays

A playback-controls HUD appears on interaction, and optional debug and benchmark overlays show live playback stats and performance numbers.
