Original video
Character enters a hallway → ordinary hallway footage → character continues walking
Add an AI VFX Scene to Your Existing Video
Your video is already taking shape. Generate one cinematic moment—a portal, magical event, sci-fi reveal, or dramatic action scene.
Step 1 · Footage & Cut Points
1. Upload your video
The selected video section is replaced with AI-generated footage. This is not precise VFX compositing over untouched original frames.
The real cat-and-teapot example demonstrates the shared scene-replacement workflow, not a tested portal, explosion, or professional VFX compositing result.
The video is already there. The cinematic moment isn't.
You've created the surrounding footage. The main character has entered the location and the story is ready for something unexpected: a portal, a strange energy event, a futuristic device activating, or a more dramatic world. Starting the entire sequence again could change the shots you already like. Generate a new cinematic scene for the selected moment and continue from your existing video.
You know what should happen. You just don't have the shot.
A science-fiction scene is missing the moment a device activates. A fantasy video needs a magical doorway. An action short needs a dramatic event between two established shots.
Traditional VFX can involve planning, filming, editing, and specialized compositing. Sometimes you want to explore what a complete cinematic replacement scene could look like, rather than build editable effects layers.
Describe the scene and generate a replacement for the part of the video that needs it.
Keep the setup. Generate the VFX moment. Return to the footage.
Updated video
Character enters a hallway → AI-generated portal scene → character continues walking
- Source footage before Start remains in the video.
- The selected interval is replaced with newly generated footage.
- The video resumes the original material after Resume.
- The total duration may change because generated length is selected independently.
- Audio inside the replaced section may change.
This creates a replacement scene, not an independently editable effect composited onto the source.

Six ideas for your next VFX scene
Glowing sci-fi portal
A luminous blue energy portal opens at the end of a deserted industrial hallway. Swirling particles surround its edges and moving blue light reflects on the walls. Slow camera push-in, realistic atmosphere, detailed textures, coherent motion, science-fiction film aesthetic.
Magical artifact activation
An ancient artifact floats above a stone pedestal in a dark chamber. Golden energy flows around it, sending a soft pulse of light across the room. Slow camera move, atmospheric dust, detailed stone, cinematic fantasy lighting.
Distant explosion
A wide shot of an abandoned industrial district at dusk. A fictional explosion erupts behind distant buildings, followed by rolling smoke and debris. Steady camera, dramatic cinematic lighting.
Futuristic hologram reveal
A large holographic projection appears above a dark laboratory console. Translucent rings and data-like patterns rotate in the air, casting cyan light onto nearby surfaces. Smooth camera move, controlled sci-fi lighting.
Supernatural room transformation
In an abandoned library at night, blue symbols glow across the walls and books rise gently from shelves. Slow pan, mysterious mood, natural-looking motion, cinematic supernatural lighting.
Energy field around a character
The fictional armored character from the references stands in a futuristic chamber as a luminous protective energy field forms and lights the floor. The character looks toward it; camera moves closer, cinematic sci-fi lighting.
Describe a complete shot: environment, focal action, lighting, and camera motion. One clear visual event is often easier to guide.
Asking for the same character, location, or object does not guarantee an exact match to source footage.

Character reference
Guide the appearance of a fictional character in the new moment.
VFX style reference
Communicate the visual mood, palette, or effect style.
Motion reference

Do you need a new VFX scene or an effect on the same original frames?
AI VFX scene generation
Replace one selected section with newly generated cinematic footage. Best for exploring a fictional visual event or alternate scene.
Traditional VFX compositing
Keep the source footage and add controlled effects with masks, tracking, rotoscoping, alpha channels, particles, or shot-by-shot compositing. Best when precise actor and camera preservation matters.
This tool is not a replacement for compositing software when exact subject tracking, actor preservation, or editable effect layers are required.
Three steps to a new cinematic scene
Create a VFX moment inside your existing video
- 1
- 2
- 3
The selected source interval is replaced; total output duration may change.
Generate VFX sceneMake the extraordinary moment feel part of your story
- Choose an interval that fits between the footage before and after it.
- Focus on one main effect rather than several unrelated events.
- Describe how the effect lights the surroundings and characters.
- Specify a clear camera movement, such as a static shot or slow push-in.
- Use references to guide established characters and environments.
- Describe a coherent short action with a beginning and finish.
- Plan how the generated scene returns to the original footage.
- Check character consistency, faces, outfits, props, and anatomy.
- Review sound because audio in the replaced section may change.
- Watch the full sequence; a striking shot can still feel abrupt in context.
Cinematic scene generation with clear limitations
What you can do
- Replace one selected scene using Start and Resume points.
- Describe fictional portals, magic, energy, sci-fi settings, and other cinematic events.
- Use up to three images and one supported short motion reference video.
- Generate 5–13 seconds and choose Standard 480p or High 768p.
- Review the completed updated video.
What this tool doesn't guarantee
- Precise VFX overlay on untouched frames; the selected interval is replaced.
- Object tracking, rotoscoping, frame-level masks, or precise placement on moving subjects.
- Transparent effect passes or separate editable VFX layers.
- Exact actor, prop, environment, or motion preservation.
- Physically accurate explosions, smoke, particles, or gravity.
- Perfect lighting, camera, color, or scene continuity.
- Automatic preservation of audio inside the replaced interval.
- Batch generation of many replacement scenes in one job.

A completed generation may still need editing; visual quality, realism, and continuity are not guaranteed.
Generate my VFX sceneFrequently asked questions
Can I add an AI-generated VFX scene to an existing video?
Yes. Upload your video, select an interval, and describe the cinematic scene. The generated footage replaces that section and reconnects to the surrounding source.
Does the tool add effects on top of my original footage?
No. The selected interval is replaced. This does not composite effects over untouched original frames.
Can I generate a sci-fi portal scene?
Yes. Describe a portal appearing or opening in a fictional environment. Results vary with the source, prompt, references, and model.
Can I create a magic effect or energy blast?
Yes. Request fantasy events such as glowing objects, spells, energy bursts, or supernatural light. Exact appearance and choreography are not guaranteed.
Can I generate a cinematic explosion?
You can request a fictional explosion or action scene. The output is a generated interpretation, not a physically accurate simulation.
Can I add a hologram or futuristic technology effect?
You can request holograms, fictional interfaces, or futuristic technology in a new scene. It does not create an editable overlay layer.
Will the original actor remain exactly the same?
Not necessarily. Face, clothing, pose, identity details, and movement can change, even with references.
Can I preserve the same room or background?
You can guide the setting with the source, prompt, and references, but exact preservation of location and geometry is not guaranteed.
Does the AI track the actor or moving objects automatically?
No. There is no traditional motion tracking, rotoscoping, tracked effect placement, or frame-level mask control.
Can I apply a VFX effect to only one area of the video?
Not with a precise mask. You can describe where an effect should appear, but the whole selected interval is regenerated.
Can I export the VFX with a transparent background?
No. The output is a rendered video scene, not a transparent alpha-channel asset or isolated effects layer.
Can I use reference images?
Yes. Up to three supported images can guide characters, environments, objects, or visual style.
Can I upload a motion reference video?
Yes. One supported reference video up to eight seconds can guide motion or camera behavior.
Can the VFX match my original video's lighting?
Describe the intended lighting, add references, and enable color matching. Exact lighting interaction and seamless continuity are not guaranteed.
How long can my generated VFX scene be?
The current workflow supports scenes from 5 to 13 seconds.
How long can my original source video be?
The source must be MP4 or MOV, 3–60 seconds, and no larger than 50 MB.
Can I replace the first second of the video?
No. Start must be at least 1.625 seconds into the source; the current interface starts at about 1.7 seconds.
Can I add a VFX scene after my video ends?
No. At least one second of original footage must remain after Resume. Extending beyond the source ending is a separate workflow.
Does the new scene have to match the removed interval's length?
No. Generated duration is selected separately, so the total output duration may change.
Will my original audio remain unchanged?
Not guaranteed. Dialogue, music, environmental sound, or effects inside the replaced interval may change. Review or restore important audio during editing.
Can I create multiple VFX scenes in the same video?
You can submit separate jobs for different replacements. The Studio does not batch-create multiple VFX scenes in one request.
Is this a replacement for After Effects or other professional compositing tools?
No. This generates replacement scenes; compositing software offers precise layers, tracking, masks, and other controls not provided here.
Can I use the generated VFX scene in commercial videos?
You may use the service for authorized projects subject to applicable terms. You are responsible for rights to footage, references, likenesses, music, and protected material.
How much does VFX scene generation cost?
Cost depends on generated duration and quality. The workspace shows the amount before you submit.
What happens if the AI generation fails?
Applicable failed jobs follow the existing credit refund process. A completed result needing refinement is not necessarily a failed job.
Can I use this for fantasy or science-fiction short films?
Yes. Request fictional cinematic scenes in an existing video, then review consistency, action, motion, lighting, and transitions.
Can I generate a scene with several effects at once?
You can describe multiple effects, but complex prompts may produce inconsistent results. One clear visual event is often easier to guide.
Is this the same as adding an Instagram or TikTok effect filter?
No. A filter changes existing frames; this workflow generates a replacement scene for a selected video interval.
