How to Create a Long Video with AI
Step 1: Share Your Idea or Script
Describe the video you want to make, or paste your script into the Agent. You can also upload human or animal reference images. Include your audience, subject, visual style, and preferred pacing to give the video a clear direction.
Step 2: Review the Storyboard
Work with the Agent to review the proposed story and storyboard. Refine the characters, sequence, and key moments before generating the video.
Step 3: Generate Your Video
Let the Agent generate the visuals and voiceover. If it asks which parts to combine, specify the full project or the sections you want included.
Step 4: Review the Finished Result
Watch the video from beginning to end. Check the story flow, character continuity, and narration, then download the finished result when it is ready.

FAQs About the AI Long Video Generator
What is an AI long video generator?
An AI long video generator turns an idea, script, or reference image into a connected multi-scene video. With insMind Agent, you can plan the storyboard, keep characters and visuals consistent, and create stories, explainers, product marketing videos, brand content, and YouTube videos with voice and sound.
How long can my AI-generated video be?
You can create videos up to 30 minutes long with insMind's AI long video generator. Choose a length that suits your story or topic, and describe your target duration when briefing the Agent. You can also create shorter videos when your idea needs less time.
Do I need a complete script to get started?
No. You can begin with an idea or a short outline and develop it with the Agent. A complete script is also a useful starting point if you already know what you want to say. Include your audience, main message, and preferred tone to help shape the video.
Can I keep the same characters throughout my video?
Yes. insMind supports character consistency across scenes. Describe each recurring character in your brief, upload a reference image when you have one, and review the storyboard to define where they appear. The Agent uses those details to keep their appearance and role consistent as the video develops.
Does the video include AI voiceover?
Yes. Voiceover is generated as part of the video workflow. Tell the Agent what should be narrated and describe the tone you want, such as warm storytelling or a clear educational explanation. Review the finished video to check that the narration and visuals communicate the same message.
Can I review the storyboard before generating my video?
Yes. You can review the proposed storyboard with the Agent before video generation. Use that stage to clarify the story sequence, character details, and key moments. Giving feedback before generation helps establish what the video should show and how the narrative should develop.
Is the AI long video generator free to use?
You can try this tool online for free. Available features and usage limits may vary by account and permissions.
What kinds of long videos can I create?
Create story videos, educational explainers, product demos and marketing videos, brand stories, tutorials, travel guides, and faceless YouTube content. Start with an idea or script, or add product and character reference images. Use the storyboard to shape the sequence, then generate a connected video with visuals, voiceover, and music that fit your audience.
Can I use my own character images?
Yes. Upload reference images of people or animals and tell the Agent who each character is. insMind uses your images to keep characters recognizable across scenes, while you shape their actions and story arc in the storyboard.
