Video export

Send the lesson as a video

MP4 or WebM, up to 4K, with your animations and transitions where you put them. No screen recording, no re-timing. Video is rendered locally, so this one lives in the desktop app rather than the browser.

Not everyone will open a slide deck

Async learners, social posts, an intranet that only accepts video — plenty of places want a file that plays. Screen-recording a deck means re-performing it every time you fix a typo.

What you get

  • MP4 and WebM output
  • Up to 4K, at 24, 30 or 60 frames per second
  • Object animations and slide transitions rendered as you built them
  • Draft, standard and high quality settings
  • Re-export after an edit instead of re-recording
  • Rendered on your own machine in the desktop app for Windows and macOS

How it works

1

Time your slides

Set animations and transitions in the editor.

2

Choose a format

MP4 or WebM, and the resolution and frame rate you need.

3

Export

The desktop app renders the video from the deck, not from a screen capture.

What this does not do

  • A video is watched, not used. Interactive questions become a picture of a question — if the point is the answering, export SCORM or share a link instead.
  • There is no video editor. Timings come from the deck's own animations and slide durations; trimming or cutting afterwards is a job for a video editor.
  • It does not record you. There is no camera overlay and no voice-over recorder — narration has to already be in the deck as audio.
  • Long decks at 4K take real time to render, because every frame is drawn rather than captured.

Questions

Is this a screen recording?

No. The video is rendered from the deck's own data, so there is no capture window, no stray cursor and no need to perform the deck in real time.

Can I include narration?

Audio you add to slides is included in the export. There is no separate voice-over recording studio inside Mosra — record elsewhere and place the audio on the slide.

What resolution should I use?

1080p suits most uses and keeps the file manageable. Use 4K when the video will be projected or when text needs to stay crisp on a large screen.
