AI SCRIPT TO VIDEO

To generate a realistic talking-head video, pick a tool that has a library of AI Avatars. Kapwing's AI Personas library has a set of stock options you can sample for free. Alternatively, train a talking head on your own short video sample and voice sample to make a video of yourself speaking. The talking head video will be powered using a synthetic text to speech voice and synced with lip sync technology on the server. As a result, it will look like you are actually speaking the words in the script.

For top performance on social media, draft a video script of at least 500 characters, which would result in a video around 30 seconds long. Here are the recommended characters and words for other video durations.

• 30-second video: 300-600 characters (80–90 words)
• 1-minute video: 750–900 characters (125–150 words)
• 2-minute video: 1,500–1,800 characters (250–300 words)
• 3-minute video: 2,250–2,700 characters (375–450 words)

Yes, AI videos be monetized on YouTube, TikTok, Facebook, Instagram, and other social media channels. Kapwing's audio, image, and video library is royalty-free. Every social media network has a unique set of community standards, copyright laws, and platform restrictions, so make sure you read them in full to best understand monetization policies. In 2025, YouTube released new guidelines saying it plans to de-monetize creators making mass-produced or repetitive content.

Based on the subject of your script, AI scans the internet and pulls B-Roll together from stock video databases. Then, it analyzes the candidate visuals, comparing them to the keywords in the script outline, to choose the best cut of the video to feature. For example, if you're making a step by step guide to scramblings eggs, the AI might choose a video of someone cracking eggs to appear earlier in the video. Each video is cut to be less than 5 seconds. Kapwing's Smart B-Roll feature uses Google's Gemini, a multimodal LLM, to get intelligence about the best video selects.

Advancements in AI have led to various concerns and confusion. Some are skeptical about using AI to assist with their work because of what may feel like a sudden jump in technology. Others are unsure about data collection. Rest assured, Kapwing is very safe to use and we have strict moderation guidelines and ethics policies in place.

Kapwing's AI Video Generator enables full customization:

- Script: After generating a script from a video prompt, edit or refine the script through our AI Script Generator. Insert emphasis, pauses, or inflection to refine the emotional tones in the video.

- Avatar: Choose the face and voice of the speaker from hundreds of options, or create an AI Twin of yourself.

- Music: Replace the suggested background tunes with your own soundtrack or audio file.

- Voiceover: After generation, edit or change the words, volume, pacing, or tone of the TTS.

- Aspect ratio: Choose the dimensions of the generated output to make it best for the platform you're publishing on

The speed of AI generation depends on the length of your script. Kapwing's AI video generator takes about 30 seconds per minute of video to generate.

An AI Persona is a digital avatar created using AI. You will notice the option to use them as part of your Script to Video generation. Kapwing has two main types of Persona offerings:

• Cloning yourself: You can clone yourself into a Persona by uploading a video of yourself speaking to the camera.
• Using a Stock Persona: Kapwing offers a range of Stock Personas, which are real people from diverse backgrounds.

To create a Persona, film a video (minimum 15 seconds) speaking to the camera, upload it to Kapwing, and name the Persona. Once your Persona is created, you can use it for individual projects or select your Persona when it appears on the 'Generate video' tab as you navigate through the Text to Video process. Alternatively, you can choose a voice from the stock library.
