Lectern — Native Screen Recorder & Editor
A native, high-performance screen recorder and editor for teachers and course creators. Screen, cameras, microphone and system audio are recorded as separate, synchronized tracks, so layouts can change after recording without recording again.

LAYER 01 // CAPTURE
Separate, synchronized tracks
Screen, cameras, microphone and system audio are recorded as separate tracks, so a layout can change after recording without recording again.
LAYER 02 // ENCODE
Hardware encoding with a fallback
Video runs through FFmpeg libraries, with no command-line spawning. Hardware encoders do the work, and software encoding takes over when they are not available.
LAYER 03 // SAFETY
Crash-safe recording
Recording is written to survive a crash, with automatic recovery. The lectern-rec tool can salvage interrupted recordings from the command line.
LAYER 04 // EDIT
A non-destructive editing engine
Split, trim, ripple delete, remove pauses, set layouts by section, undo and redo. Originals are never modified: editing only changes project data.
LAYER 05 // RENDER
One compositor for preview and export
The same compositor and audio mixer drive preview and export, so what you see and hear is what you export.
LAYER 06 // CREATE
Tools made for course creators
Text presets, subtitles in SRT and VTT, overlays, effects, colour, an audio mixer and music, all inside the editor.
LAYER 07 // DELIVER
Finished MP4 export
H.264 and AAC export through the hardware encoder, also available from the command line with lectern-export.
