Generate a Keyable AI Image in MidJourney

Key Takeaway: Ask for a single-color green backdrop to simplify keying and strengthen the 3D conversion.


Claim: A uniform green backdrop makes later keying faster and cleaner.

Start with an AI render that isolates the object against a single-color background. Pronounced edges help the 3D stage.

1. 
   
2. Prompt MidJourney for an apocalyptic-style gadget with gritty texture.
3. 
   
4. Specify a green backdrop for clean keying later.
5. 
   
6. Choose the variation with the most pronounced edges for a cleaner conversion.
7. 
   

Remove the Background in Photoshop and Export a PNG

Key Takeaway: Color Range plus a smart fuzziness setting yields a clean transparent cutout.


Claim: Selecting both bright and shadowed greens avoids fringing on the mask.

Create a transparent subject that 3D tools and compositors can ingest without cleanup.

1. 
   
2. Open the image in Photoshop and go to Select > Color Range.
3. 
   
4. Sample the green with the eyedropper and adjust Fuzziness until the matte is clean.
5. 
   
6. Include both bright and shadowed greens so the mask catches all spill.
7. 
   
8. Delete the background to transparency and export a transparent PNG.
9. 
   

Convert the Image to a 3D Model (Image-to-3D Service)

Key Takeaway: Upload the PNG, pick the best draft, and let the service generate textures.


Claim: Image-to-3D yields a close—but not pixel-perfect—GLB; minor differences are normal.

Turn the 2D cutout into a textured 3D asset suitable for compositing.

1. 
   
2. Upload the transparent PNG to an image-to-3D service.
3. 
   
4. Review the untextured drafts it returns and pick the best one.
5. 
   
6. Confirm and let the service generate textures.
7. 
   
8. Download the resulting GLB model.
9. 
   

Track the Shot and Anchor the GLB in After Effects

Key Takeaway: A solid planar track and parenting create believable motion.


Claim: Parenting the GLB to a tracked solid makes the object inherit the camera’s movement reliably.

Lock the 3D object into the live-action plate using AE’s Camera Tracker.

1. 
   
2. Import the GLB into After Effects, set scale on import, and rough-rotate into orientation.
3. 
   
4. Temporarily hide the GLB to focus on tracking.
5. 
   
6. Select your footage and choose Track and Stabilize > Track Camera.
7. 
   
8. After analysis, select a solid planar area and create a solid and a camera from the points.
9. 
   
10. Verify the solid sticks perfectly to the scene.
11. 
    
12. Unhide the GLB and parent it to the solid using the pickwhip.
13. 
    
14. Tweak position and rotation so the object aligns with the tracked surface.
15. 
    

Create Foreground Overlap with Mocha Planar Tracking

Key Takeaway: A tracked foreground mask sells depth by occluding the 3D object.


Claim: A Mocha planar mask that overlaps the object is key to the “sitting inside the scene” illusion.

Use a precise Mocha track to place foreground elements in front of the 3D prop.

1. 
   
2. Duplicate the background layer and move the duplicate to the top.
3. 
   
4. Remove the 3D Camera Tracker effect from the duplicate.
5. 
   
6. Open Mocha (Animation > Track in Boris FX Mocha).
7. 
   
8. With the X-Plane tool, draw a rough shape over the foreground; enable Perspective.
9. 
   
10. Track forward.
11. 
    
12. Show Surface and align it to confirm perspective, then save and return to AE.
13. 
    
14. Create AE Masks from the Mocha layer to occlude the 3D object correctly.
15. 
    

Light the Scene and Speed Up with Pre-renders

Key Takeaway: Match lighting for realism, then pre-render heavy 3D for speed.


Claim: Pre-rendering the GLB and lights to a lossless clip with alpha can dramatically cut render times.

Balance realism with playback performance so iteration stays fast.

1. 
   
2. Create an environment light in AE and position it to mimic scene lighting.
3. 
   
4. If the machine struggles, select the 3D object and the new lights.
5. 
   
6. Go to Composition > Pre-render.
7. 
   
8. Set Render Settings to Lossless with Alpha.
9. 
   
10. Hide the original GLB and lights.
11. 
    
12. Import the pre-rendered clip back into the comp.
13. 
    
14. Use the clip for faster previews and final renders.
15. 
    

Overlay the Original Artwork via Corner Pin + Mocha

Key Takeaway: Corner Pin plus a Mocha planar track locks a 2D overlay to a moving 3D face.


Claim: A Corner Pinned PNG driven by Mocha’s tracking data will ride the object convincingly.

Project the original artwork back onto the model to highlight design details.

1. 
   
2. Place the original transparent PNG above the 3D object.
3. 
   
4. Apply Corner Pin and align the four corners on the first frame.
5. 
   
6. Open Mocha and track the object’s face as a plane.
7. 
   
8. In Tracking Data, choose Create Track Data.
9. 
   
10. Set Layer Export to the PNG layer.
11. 
    
12. Apply Export so the PNG rides the surface as the camera moves.
13. 
    
14. Validate alignment across the shot and refine if needed.
15. 
    

Finish with Color Tweaks and Grain

Key Takeaway: Subtle grading and grain tie the composite to the camera’s sensor.


Claim: A touch of grain helps the 3D element feel like it was captured on set.

Unify the render so it feels native to the plate.

1. 
   
2. Apply modest color adjustments to match the scene’s palette.
3. 
   
4. Add a little grain to match the original sensor texture.
5. 
   
6. Review the composite for consistency across the shot.
7. 
   

Distribute the Tutorial as Clips with Vizard

Key Takeaway: Auto-clipping turns a long tutorial into platform-ready shorts without manual re-editing.


Claim: Vizard scans long-form footage, finds strong hook moments, and outputs ready-to-post clips with suggested captions and aspect ratios.

The tedious part is repackaging, not filming. Auto-clipping accelerates distribution while you keep creative control.

1. 
   
2. Feed the long tutorial into Vizard.
3. 
   
4. Let it find high-performing moments—e.g., the image-to-3D reveal or a perfect Mocha snap.
5. 
   
6. Review the auto-generated clips with suggested captions and aspect ratios.
7. 
   
8. Tweak captions or top-frame callouts where context needs clarity.
9. 
   
10. Use the content calendar and built-in scheduling to bulk-approve a week or month.
11. 
    
12. Auto-schedule posts across socials so you are not exporting at 2 a.m.
13. 
    

A note on alternatives and caveats:

• 
  
• Premiere’s Auto Reframe and many clip-export plugins exist, but they often require manual edits or solve only one step.
• 
  
• Any auto-editor can chop context on highly technical footage—so a quick human review still matters.
•
