What do I need to write?
One sentence is enough, for example "three surprising facts about octopuses". The more specific you are about the angle and the audience, the sharper the script. You can also paste a rough script.
Can I choose how long the video is?
Yes. Choose 15, 30 or 60 seconds. The script is fitted to that length so the voiceover is not cut off and the video does not run long.
Can I change the voice?
Yes. Open the advanced settings to choose a voice model and one of more than 50 voices. If you leave it alone, Uma uses a natural default.
Where do the pictures and clips come from?
From licensed stock libraries. Meme cards are made from licensed photos with captions from your own script.
What if the video fails?
The credits for that video are returned to your balance automatically, so you only pay for videos that finish.
Can I edit the result?
You can download the MP4 and edit it anywhere. To change the script, voice or style, make a new version, which costs the same credits again.
