Cast FAQ
Everything people ask before making their first AI character video with Cast.
- What is Cast?
- Cast is a mobile-first AI video app made by Katechon. You pick a character, type one line about what they do, and Cast generates a short vertical video that lands in your own private feed. It runs in any phone browser, including TikTok's and Instagram's in-app browsers.
- Is Cast free?
- Your first 5-second video is free and needs no sign-up: Cast gives new visitors 55 credits, enough for one 52-credit Standard video, while the day's free-video allowance lasts. After that you buy credits, starting at $4.99 for 450 credits.
- How much does a video cost?
- A Standard video (Seedance 2.0 Fast, 720p) costs 52 credits for 5 seconds, 99 for 10 seconds and 146 for 15 seconds. A Pro video (Seedance 2.5, 1080p, Premium only) costs 493, 976 or 1,458 credits. The price is shown on the button before you generate.
- Do I need an account?
- No. Your first tap creates a guest account, so it works inside TikTok and Instagram, where Google sign-in is blocked. From a regular browser you can also sign in with Google.
- Who are Malfoid, Thea, Odette?
- They are the Malfoid & Friends pack: the snobbiest girl at boarding school and her two best friends. The pack is free for everyone, and you can put one, two or all three of them in the same video.
- Can I make my own character?
- Yes. Describe a character in words, pick a style, and Cast draws four looks to choose from. A character costs 15 credits (22 for HD looks on Premium). Once picked, you can cast them in any video.
- How long can videos be?
- 5, 10, 15 seconds. Without Premium, videos run up to 10 seconds; Premium unlocks 15-second videos.
- Who can see my videos?
- Only you, unless you choose otherwise. Videos land in your own private feed and the files are served only to your session. Each video has a public/private switch (off by default): switch it on and the video gets a public page at cast.katechon.technology/v/<id> showing the video, your prompt and its characters; switch it off and the page and file disappear at once.
- What happens if a video fails?
- The credits are refunded automatically. A render that is still pending after two hours is given up on and refunded too.
- What is Premium?
- Premium is $19.99 a month: 2,000 credits every month, Pro videos (Seedance 2.5 at 1080p), videos up to 15 seconds and HD character images.
- Which AI models does Cast use?
- Videos: ByteDance Seedance 2.0 Fast (Standard, 720p) and Seedance 2.5 (Pro, 1080p). Character looks: Midjourney v8.2. Prompt writing: a Claude model. All of it runs through Atlas Cloud.
- How do I pay?
- Through Stripe Checkout, in US dollars. Credit packs are one-time purchases; Premium renews monthly.
