If you want to make videos longer than the default clips in Sora 2, it’s entirely possible with a simple workflow. By generating consecutive clips and using the last frame of each as a starting point for the next, you can create seamless, extended videos. I recently made a 30-second anime sword fight video using this method, and it can be repeated indefinitely to make videos of any length.
Note: Sora 2 now allows 15-second clips for regular users and 25-second clips for Pro users, which makes extended video creation even easier.
Access to Sora 2 still requires an invite, but there’s no need to worry if you don’t have one. Global GPT has integrated Sora 2, allowing free access without an invite, with fewer content restrictions and no watermark issues.
Step 1: Generate Your First Sora 2 Video
Start by creating the first clip of your video in Sora 2. For my example, I wanted a sword fight between two anime characters. I prompted Sora 2 to end the clip with one of the characters falling down. Once the video is generated, download this initial clip. This first clip sets the stage for all subsequent footage and ensures continuity in your video narrative.
Step 2: Extract the Last Frame of the Sora 2 Video
Next, upload the first clip to ChatGPT (or any frame-extraction tool). Ask it to extract the last frame of the video and provide it as an image file. Download this image—it will serve as the reference point for your next clip. This step ensures that characters and backgrounds remain consistent across multiple clips, making the extended video appear natural.
Step 3: Generate the Next Clip
Return to Sora 2 and create the second clip. Click the plus button to upload the last frame image you just downloaded. Then, provide a prompt describing what happens next, starting from how the first clip ended.
Example:
- First clip ends with a character on the ground.
- Second clip prompt: “The fallen warrior gets back to his feet quickly and resumes the sword fight.”
Generate the next clip. This ensures that the action flows naturally from one clip to the next while maintaining consistent character poses and scene elements.
With the updated clip limits, regular users can now generate 15-second clips, and Pro users can generate 25-second clips, reducing the number of clips needed for longer videos.
Step 4: Stitch Clips Together
Once you have multiple clips, combine them in a video editor. I used this method to create a 30-second video by stitching together two or three clips depending on the user tier. This approach can be repeated indefinitely—each new clip builds on the last frame of the previous one. By following this workflow, you can generate videos as long as you need, all while keeping characters and settings consistent.
Step 5: Handling Watermarks
One thing to note is that clips generated with the standard Sora 2 may include animated watermarks. However, if you use Sora 2 integrated within Global GPT, videos are generated without any watermarks, allowing you to create polished, final videos directly without extra editing.
Step 6: Tips for Seamless Extended Videos
- Keep continuity in prompts: Always describe how the previous clip ended.
- Maintain consistent character poses: Upload the last frame as reference for the next clip.
- Plan your story in advance: Sketch the full sequence so each clip flows naturally into the next.
- Use a video editor to merge clips: Any standard editor (Premiere, Final Cut, DaVinci Resolve) works.
- Manage file sizes: Extended videos can become large; consider exporting clips individually in high quality before stitching.
Real Example: 30-Second Sword Fight
I recently applied this workflow to create a 30-second anime sword fight.
- First 15-second clip: One character falls.
- Last frame extracted and uploaded.
- Second 15-second clip: Fallen character rises and continues fighting.
- Clips combined in a video editor.
The result was a seamless, continuous 30-second fight, which can be extended further using the same workflow.
Conclusion
By following this workflow—extracting the last frame, using descriptive prompts, and stitching clips—you can create videos of any length in Sora 2. With the updated clip limits of 15 seconds for regular users and 25 seconds for Pro users, extended video creation is even easier. This method maintains character and setting continuity while giving you full creative control over extended AI-generated content.
