The solution to fragmented AI video generation
People who make short AI video often run into three bottlenecks: very short clips, separate tools for voice and lip-sync, and low-resolution output that needs an external upscaler. BetterVideo brings these into one workflow: clips up to 20 seconds from a sentence or a photo, built-in music or a voiceover, a talking photo with lip-sync for faces (4 or 8 seconds), Full HD or 4K delivery, and a built-in enhancement pipeline, all paid for from one credit wallet.
What you get
- A finished video up to 20 seconds long, made from one sentence
- AI-generated music in ten styles, or an AI voiceover in a male or female voice that reads your script
- Full HD 1080p or 4K Ultra HD, in horizontal 16:9 or vertical 9:16
- Automatic enhancement: every video is sharpened and upscaled before you download it
- No visible watermark, and you keep your rights to what you make, to the extent the law allows
- Ready in a few minutes. You can close the page and we email you when it is done
How length and price are worked out
You do not pick a length. If you add a voiceover, the length follows your script, at about two and a half words a second. With music only, the video is 8 seconds. A short script makes a 1-credit video, and the longest, up to 20 seconds, costs 4 credits. 4K costs double.
What to know before you start
- Each video is one continuous clip, up to 20 seconds. It is not a multi-scene editor.
- Videos are created at 720p, then enhanced to Full HD or 4K. The extra sharpness comes from enhancement, not from a higher-resolution original.
- Say what you want to see: the subject, the light and the camera move. A vague sentence gives a vague video.
- Creating videos needs a credit pack, from $9. The free signup credit is for enhancing videos you already have.
How it works, step by step
- Write your sentenceDescribe the subject, the light and how the camera moves.
- Choose the soundPick music in one of ten styles, or write a script and choose a voice.
- Pick the formatFull HD or 4K, horizontal or vertical.
