Method 1 - Cover screenshot with ‘see more’ swipe up:
This is preferable if the story contains interactive elements/attachments that would not work as a video format.
Method 2 - Creating a screencast of the whole story
Note: It is still recommended to add a swipe up that links to the actual Web Story.
Awesome Screenshot is a free tool that can be used for recording screencasts with sound and then downloading the result as an MP4 (which can then be uploaded to the social media platform):
Alternative similar tools do exist e.g. Screencastify.
Step 1 - Open a preview URL and remove /amp and add ?opts=remove:grid-sound-share-progress to the end:
This removes all visible controls that would conflict with the native controls on e.g. Instagram.
Step 2 - Open the browser inspector (Right click > Inspect in Chrome) and switch to mobile device view.
The story should look how it would on a real mobile device but without any controls or progress bars visible:
Step 3 - Start recording and then while recording click through the story at the desired pace.
Tip: Click back on the story before starting to record, and then use the arrow keys to navigate through the scenes to avoid a visible cursor appearing in the recordings.
If using Awesome Screenshot, you want Record > This Tab (and make sure that the sound toggle is on if there is video with sound).
Step 4 - Download the video as an MP4 file, ready to upload on the platform of choice.
Step 5 - Optionally, split the video by scene into separate clips using a video editing tool, to match the scene transitions with those on the third-party platform.
