In some cases, you may find that an embedded video isn't synchronized with its audio when viewing HTML5 output in mobile Safari.
This is a known issue. It can occur when using low bitrate audio. Here's how to avoid this behavior:
- When publishing, click the Quality option.
- Drag the Audio bitrate slider to 160 kbps.
- Click OK to close the Publish Quality window, then complete the publishing process.
