When you create a Scroll-Stopping Ad or a Hero Image, there will be a little 'cinema' button on the bottom right. Click that to generate a 1-second video:
Once created, you'll have the option to download it, so you can then stitch it into a larger video using any video editing software. Some popular video editing software are Canva and Veed.io.
Please note: For the 'Scroll-Stopping Ads', the video button is only available when in 'landscape' mode in the Advanced Settings. We hope to have Portrait mode videos available soon.
