What video format should I use?
Edited

.MP4 (recommended)

For more advanced users who are comfortable exporting video and adjusting quality settings, we recommend using .mp4 videos for complete control over quality and performance.

YouTube

YouTube is a free video hosting service with the easiest setup process for Impulse. Create an account, upload an unlisted video in any format that YouTube supports, and use the YouTube link on any video-supported section.

YouTube recently added restrictions to their API, removing minor features that will cause your video titles to appear briefly at the start. Because of this, we now recommend MP4 videos for the most seamless experience.

Vimeo

Vimeo is a video service similar to YouTube. Impulse is compatible with Vimeo but because of their outdated API, some features are not be supported (ex: no autoplaying on mobile devices, no control-free video player).
