Customize Video and Audio Lessons

A few lesson-level details for a more polished, accessible course.

Add subtitles and closed captions

1. Choose Upload Subtitle.
2. Select a .srt file and its language.
3. Save.

Refine with the built-in caption editor (timeline or raw text). Multiple languages supported per video.

Choose a custom thumbnail from the video itself

1. Pause on the frame you want.
2. Click Use current frame as thumbnail.

Or upload a separate custom thumbnail instead.

Add audio lessons

1. Add a lesson, choose audio as content type.
2. Upload MP3, AAC, or WAV.

Thumbnails pull from the lesson thumbnail. Playback speed adjustable. Snapshot/cloning doesn't extend to audio files — rebuild manually when duplicating into a new account.
