To record your screen:
Select the Record button in the top menu of Synthesia.
There will be three options presented: record the entire screen, a specific window, or a Chrome tab.
If you've already typed your script in the Script Box, it will begin playing automatically when the recording starts. This feature helps to synchronise the screen recording with the audio.
After finishing the recording, return to your Synthesia video page and press either Stop or Stop sharing on the screen you are currently on.
The recording will display on the canvas.
If required, you have the ability to trim your video. See the How do I trim a video in Synthesia? guide to learn how to do it.
Notes:
Each recording can be a maximum of 5 minutes.
The screen recording is saved in the Media Library and becomes an asset that you can reuse in the future.
