How To Make Longer AI Videos Without Stitching Clips
Solves the traditional problem of stitching fragmented short clips by leveraging native 30-second generations and continuous extension functions.
What this lesson covers
This tutorial shows how to produce continuous 60- to 90-second AI film sequences using Seedance 2.5's video extend feature within Topview's Film Studio. By utilizing canvas nodes, underlying LLM agents, and locked character assets, filmmakers can eliminate manual clip stitching and choppy cuts.

- 02:14 ↗
Extending native 30-second video generations creates 60- to 90-second continuous tracking shots without breaking character locking.
- 03:45 ↗
Prioritizing one-take tracking shots in scripts yields grounded cinematic realism compared to frequent cutaways.
- 05:57 ↗
Topview Film Studio's node-based canvas visualizes storyboards, reference assets, and video iterations in a single interactive map.
- 07:07 ↗
Sending feedback directly to the agent by tagging specific canvas nodes allows targeted asset updates without re-prompting from scratch.
Workflow outlined in the video
- Upload the AI filmmaking skill markdown file into Topview Video Agent.
- Write an action script that specifies continuous tracking shots and minimal camera cuts.
- Configure the workflow to generate reference assets via GPT Image 2 and draft videos at 720p using Seedance 2.5.
- Select a underlying cinematic agent LLM (such as Claude Opus 4.8) based on project complexity and credit budget.
- Generate 8-panel character reference sheets and prop objects directly onto the Topview Film Studio canvas.
- Render the initial 30-second scene and apply the extend forward function to create 60- or 90-second takes.
