Video & Audio Optimisation

When working with video or audio there is a hard limit on the file size that will be accepted. These limits ensure that files don't bloat your story to exceed your story limit, and to ensure that audio & video playback runs smoothly on low-end devices.

Videos need to be saved as .mp4 with 16:9 aspect ratio. To decrease the size of videos we recommend using The maximum permitted size per video is 15MB.

Consider your audience when creating videos. Internet access & speed as well as device quality may affect content load times.

To add episodes from an external podcast, a link to the iTunes podcast or a valid RSS podcast feed must be added.
