App promo video maker
Your launch post, brought to life. LaunchHerald animates the design you already made — the headline rises in, the phone floats, your screens swipe — over one of 14 moving backgrounds, ready for Reels, TikTok and YouTube Shorts.
What you get
Your design, animated
No timeline to learn: the post you designed becomes the video, with motion added for you.
14 moving backgrounds
Aurora, neon grid, 3D cubes, bokeh, confetti, light rays and more, in your app's colours.
Screens that swipe and scroll
Phone screenshots swipe; laptop screenshots click through; tall ones scroll.
Every shape
9:16, 4:5, 1:1 and 16:9 from the same design.
How it works
Design a post from your screenshots (AI writes the headlines).
Open Video, pick a motion backdrop and a length.
Download the MP4.
Questions
How long are the videos?
Promo videos run 5–10 seconds; 3D mockup videos up to 20 seconds.
Do the videos have sound?
No — they're silent clips, which is how most people watch social video. Add music in TikTok or Instagram if you like.
Can I use a screen recording?
Yes. Add MP4 or MOV clips alongside or instead of screenshots.
