Reaction shot
A character hears an unexpected sound, freezes, and slowly turns.
Add a New Character Scene to Your Existing Video
Your character is already in the story. Generate the action or reaction shot you are missing.
This workflow replaces a selected section of your source video. References guide appearance but do not guarantee exact identity or continuity.
Step 1 · Footage & Cut Points
1. Upload your video
This real demo features an AI-generated cat and a teapot. It demonstrates general scene replacement and timing, not verified human-character consistency.
Generate the scene you need without recreating the entire sequence
You've spent time creating your character and assembling a short video. But a reaction shot, entrance, or action is missing. Work from your existing clip and generate a new scene for the moment that needs attention.
Keep the opening. Change the character moment. Continue the story.
Original video
Original footage → unwanted or missing action → original next scene
Updated video
Original footage → AI-generated character action → original next scene
- Footage before Start remains part of the surrounding video.
- The selected interval is replaced with generated footage.
- Original footage resumes at your selected Resume point.
- Generated duration may differ, changing the total video length.
- Audio inside the replaced interval may differ.
This is scene replacement, not character compositing over untouched frames.
Give your character something new to do
Walk or enter
A detective approaches a doorway and pauses before entering.
Emotional performance
A character reads a letter, takes a breath, and looks up thoughtfully.
Character reveal
A cloaked traveler emerges from a misty passage as the camera moves closer.
Object interaction
An explorer lifts and inspects an old compass on a table.

Show AI who should appear in the new scene
References provide visual guidance, but facial structure, clothing, accessories, proportions, or style may still change.
Main appearance
Use a clear front or three-quarter view showing the face and outfit.
Another angle
Add a side view to show hairstyle, costume, and proportions.
Outfit or style details
Include important costume details, props, or visual style.
Optional motion reference
Add one short clip to guide movement or camera behavior.
Six example character scene prompts
Suspenseful reaction
A detective in a dim hallway hears a sound behind a door, slowly turns, and pauses with concern. Keep the reference hairstyle and jacket; cinematic medium shot, subtle handheld camera.
Fantasy entrance
An armored adventurer enters a foggy courtyard, walks slowly, stops, and looks around. Match the visible armor and cloak as closely as possible; smooth tracking camera.
Emotional close-up
A woman beside a window reads a folded letter, pauses, then raises her eyes thoughtfully. Soft natural light and a gentle camera push-in.
Animated reaction
An illustrated fantasy character notices a glowing object, leans forward in surprise, and cautiously reaches out. Match the reference palette and style as closely as possible.
Sci-fi action
A futuristic soldier moves along an industrial corridor, hears something, turns, and takes cover. Controlled cinematic camera and realistic movement.
Simple interaction
The character picks up a compass from a desk, examines it, and puts it back. Stable medium shot, warm indoor lighting.
Describe who appears, one connected action, the setting, and camera behavior. Identity-matching language guides the model but is not a guarantee.

Add a character scene in three steps
- 1
Upload your existing video
Use an authorized MP4 or MOV clip, 3–60 seconds and up to 50 MB.
- 2
Choose the scene and action
Set Start and Resume, describe one action, and optionally add up to three images or one short motion reference.
- 3
Generate and review
Choose duration and quality, then inspect identity, motion, transitions, and audio.
Help the new scene fit your story
- Think about the shot before and after the replacement.
- Choose natural Start and Resume points; leave at least one second after Resume.
- Keep the prompt focused on one coherent action.
- Use clear, consistent references and avoid contradictory images.
- Describe camera and lighting that suit the surrounding footage.
- Review faces, hands, clothing, props, transitions, and audio in the full output.
Generate a character scene, not a guaranteed character clone
What you can do
- Replace one selected section of an existing video.
- Describe a new character action, reaction, setting, and camera direction.
- Use up to three reference images and one motion reference video up to 8 seconds.
- Generate a 5–13 second scene at Standard 480p or High 768p.
What is not guaranteed
- Exact face, outfit, accessory, or proportion consistency.
- Precise body mechanics, choreography, or object interaction.
- Exact camera continuity with surrounding source footage.
- Preservation of original audio within replaced footage.
- Compositing a character onto untouched frames or generating a whole multi-shot story automatically.

Frequently asked questions
Can I insert a new character scene into an existing video?
Yes. Upload a video, choose the interval to replace, describe the action, and generate a new scene. The output resumes the original footage after your Resume point.
Does the tool add a character without removing original footage?
No. Footage between Start and Resume is replaced; the tool does not composite a character over untouched frames.
Can I use reference images of my character?
Yes. Add up to three supported images to guide appearance, clothing, hairstyle, proportions, or style.
Will the character look exactly the same in the new scene?
No. Facial features, clothing, proportions, and small design details can change even with references.
Can I add a missing action to my AI short film?
Yes. Generate a character-driven replacement for a selected interval and review whether it fits your story.
Can I generate a character reaction shot?
Yes. Describe the emotion and response. Expression and performance quality may vary.
Can I make my character walk, turn, or interact with an object?
You can request these actions. Complex motion and object interaction may contain visual or anatomy errors.
Can I use anime or illustrated characters?
Yes. Provide stylized references and describe the intended style. The output may still differ from the original design.
Does it work for realistic human characters?
Yes, with footage and references you are authorized to use. Exact likeness and natural movement are not guaranteed.
Can I insert a completely new person into a live-action shot?
This is not a person-compositing tool. It generates replacement footage for the selected interval.
Can I upload three different angles of the same character?
Yes. Add up to three reference images, such as different angles or detail views.
Can a short video guide the character's movement?
Yes. One optional reference video of up to eight seconds can guide motion or camera behavior.
Do I need the original character prompt or seed?
No. Your source video, scene description, and optional references are enough to start.
Can I use the same character in multiple scenes?
You can reuse references in separate jobs, but consistent identity across outputs is not guaranteed.
How long can the generated character scene be?
The current workflow generates scenes from 5 to 13 seconds.
What is the maximum source video length?
Source videos can be 3–60 seconds and up to 50 MB.
Can I replace the very first second of my video?
No. Start must be at least 1.625 seconds into the source; the earliest slider point is about 1.7 seconds.
Can I replace the final scene of my video?
The workflow requires at least one second of original footage after Resume, so it cannot replace through the final frame.
Does the generated scene need to match the removed footage's length?
No. Generated duration is selected separately, so total output length may change.
Can I keep the character's original dialogue?
Audio inside the replaced interval is not guaranteed to be preserved. Plan to review and edit it if needed.
Can I choose camera angle and lighting?
Describe framing, movement, lighting, and environment in the prompt. The model may not follow every instruction precisely.
Can I generate a scene without an existing video?
No. This workflow requires a source video. Use a video or character animation generator to start from scratch.
Can I generate several character scenes in one job?
No. One generation replaces one selected interval. Multiple scenes require separate jobs and editing.
What video quality is available?
Standard is 480p and High is 768p.
How much does character scene generation cost?
Cost depends on generated duration and quality. The workspace displays the credit amount before submission.
What happens if generation fails?
Failed jobs follow the service's applicable credit refund process. A completed result needing revisions is not automatically a failed job.
Can I use the generated character scene commercially?
Use only source material and references you have rights or consent to use, and follow the applicable service terms.
Is this a face-swapping or identity-cloning tool?
No. This is generative scene replacement with visual reference guidance, not identity locking or face swapping.
One missing character moment doesn't have to mean starting over
Choose the part of your existing video that needs another action, guide the AI with character references, and generate a new scene for your story.
