This is for when you have uploaded your slides and a pre-recorded video, and you want to add the slide timings manually.
Here’s the how to video:
And here is a written explanation:
Click on the ‘Manual Sync’ button as opposed to the ‘Visual Sync’ button so you arrive at this page.
For using the manual sync, you need to know the timings of when the slides change.
The first slide is always set to zero and you can’t change that but from slide 2 you can enter in your slide queues in minutes and seconds. When you’ve finished, click preview. It’s good to check it through before you publish. If all the timings are present and correct, click save timings and you’re done, if not go back and adjust until you’re happy.
