Frequently Asked Questions

How to Generate a Video on Kapwing with Kai
To access the AI Video Generator, click the easel icon in the top bar or enter your topic into the text box in the empty Studio view. Our AI Video generator can create Scenes, videos with stock b-roll, and videos with AI avatars.
Once in the AI Video Generator, write a clear prompt to guide the AI into creating the video you want.
- If you have an image or clip you want to work off of you can upload it by first clicking the "Attach media" button.
- You can then select the slider setting icon on the right to choose your AI model preferences. If you’re unsure which model to use, simply leave it as is and Kapwing will automatically select the best model based on your prompt.
- Before generating you can look at the sample options for ideas on what to use our Kai Video Generator for or for sample prompts.
- Finally, you can type in whatever details you would like in the text box.

Once your video has been generated, you can update your prompt to try again for a video more aligned with that you want, edit in Kapwing, or click download.
How Is My Generated Video Formatted?
If you do not write the size you would like your video to be within your prompt, the AI will decide for you depending on the rest of your prompt. For example, if you request a video for a Reel, the AI will assume you want the video to be sized 9:16. If you upload starting media that is 4:5, the AI will assume you want your video to be generated 4:5.
Here is a list of popular size ratios for social media to refer to when writing your prompt:
- 1:1 - Instagram posts, Facebook pictures
- 9:16 - TikTok, YouTube Shorts, Instagram Reels, Snapchat
- 16:9 - YouTube, Twitch
- 4:5 - Instagram or Facebook videos
- 5:4 - Instagram or Facebook videos
Prompt History
Kapwing remembers your past prompts on the left side of Kai under "Chats".
If you want to iterate on your prompt or remember previous generations, browse through your past chats. This prompt history is specific to a user, not the full workspace, so your prompts will not be shared with coworkers without your permission.

How Do I Make a Multi-Scene Video?
To create a video with multiple scenes, first select the sliders setting icon to change the model preference for video to Seedance. Then, include the phrase 'the camera switches' in your prompt to signal a scene change.
How Do I Generate Another Video?
If you'd like to generate a new video, you can simply re-write your prompt with updated language and phrases in the same chat thread. If you find that the AI Generated Video output isn't exactly what you were looking for, edit the video within Kapwing Studio to update images, videos, subtitles, music and more.
Our AI tools including the video generator are part of your plan's text to speech (TTS) minutes. If you are unable to generate a video, please review your limits to ensure you haven't used them up for the month.

How Do I Make a Video Longer than 12 Seconds?
To create a video that maintains the same narrative and visual structure from a short clip you've already made, follow these steps:
- Add your AI video clip to the Kapwing studio
- Right-click on your video where it ends and select "Freeze Frame."
- Download the frozen frame from within your Media tab by clicking the download icon
- Head back to the Kai AI generator and upload the freeze frame to the "Attach Media" section as a reference.
- Enter your Al prompt and generate the next part of your video.
- Add the new clip to your project by selecting edit in Kapwing and then copying the clip over to the original project.
You can repeat this process as many times as needed to build one cohesive narrative.
Does Kapwing Support AI Image Generation?
Yes! Kapwing's AI Image Generator is available in the same Kai AI generator.
When you submit your prompt, Kapwing will generate an image using a generative AI model. Be sure to say you want an image in your prompt so the AI doesn't generate a video instead.
