Picture this: you're staring at your VEO3 interface at 2 AM, desperately trying to craft the perfect prompt for that complex lightning strike scene, but every attempt feels like throwing spaghetti at the wall. You know the AI can create mind-blowing visual effects, but getting it to understand exactly what you need feels like speaking different languages. Sound familiar?
These 12 battle-tested prompts transform your VEO3 workflow from guesswork into precision craftsmanship, covering everything from seamless object replacement to explosive composites with heat distortion. Each prompt comes ready to copy and paste, complete with technical specifications, realistic examples, and recommended AI assistant pairings that professional VFX artists actually use. Stop wrestling with vague descriptions and start creating Hollywood-quality visual effects that nail the brief every single time.
1
Accurate 3D Camera Solve (Matchmove)
Analyze footage: file name [scene_walk_01.mov], frames 1200–1600, 1920x1080, 23.976 fps. Provide a full 6DOF camera solve and lens distortion model. Ignore visible handheld marker at lower-right and a moving car between frames 1300–1350. Output: FBX camera (with focal length, principal point, distortion coefficients), per-frame camera transforms (CSV), and an optional depth proxy mesh for frames 1400 and 1500. Mark reliable 2D track points and a confidence score per track.
Generate a precise 3D camera solve and exportable camera + lens data for compositing CG into live-action footage. Include required frame range, tracking markers to ignore, and desired export format.
2
Seamless Object Replacement (Prop Swap)
Replace handheld phone with a CG gadget from frame 432 to 678 in plate phone_scene.mov (30fps, 4K). Provide cut/matte per frame for hand occlusions, edge feathering recommendations, and a specular highlight pass. Suggest lighting HDRI capture angles and camera-relative placement coordinates for the CG object. Deliver alpha matte, occlusion matte, and a short compositing checklist.
Plan a prop replacement: provide precise roto guidance, required mattes, occlusion handling, lighting matching, and plate prep for the VFX artist.
3
Realistic Dust and Debris Interaction
Generate dust and light debris simulation for actor jump in plate jump_run.mov frames 200–270 (24fps). Use collision proxies from tracked actor geometry, two wind layers (gentle crosswind and short gust at frame 232 lasting 6 frames), and vary particle scale 0.02–0.1m. Output: particle simulation cache (Alembic), beauty, depth, and velocity passes. Include shader notes for thin dust scattering under tungsten-light conditions.
Create particle-based dust/debris that reacts to actor movement and wind; provide emitters, collision proxies, and render layers for compositing.
4
Dynamic Lightning Strike VFX
Add a lightning bolt striking the rooftop at frame 512 in night_rooftop.mov (24fps, 4K). Bolt path from left ridge to center chimney; duration 4 frames bright then 18-frame fade. Provide separate high-frequency flicker luminance pass, contact burn alpha, animated light bloom, and per-frame exposure offset for nearby objects. Include GPU-friendly render settings and motion-blur parameters.
Design a lightning strike timed to footage: specify bolt path, glow/flicker animation, contact burn, light wrap, and frame-by-frame intensity curve.
5
Glass Shatter with Accurate Reflections
Simulate tempered window shatter in office_window.mov frames 800–920 (30fps). Use impact point at pixel coord 960x540, generate shard level-of-detail with smaller pieces near impact. Provide reflection/refraction AOVs, shard ID matte, contact dust, and per-shard velocity. Match on-set HDRI provided (hdri_office_02.hdr). Export shards as Alembic and beauty/exr passes.
Simulate a glass pane shattering with correct reflection/refraction, shard trajectories, and match to on-set lighting and camera motion.
6
Night-to-Day Color Transformation
Transform night_interior.mov (24fps, 2K) frames 1–300 into a daytime plate. Replace window exterior with sunny street HDRI (hdri_day_bigcity.hdr), add warm sun shafts at 10:30° elevation, shift white balance to 5600K, increase fill light on actor by +0.8 stops, and tone-map highlights for 14-bit output. Provide grade presets and mask for practical lamps to remain lit at lower intensity.
Convert a night interior scene to believable daytime: adjust lighting, add sun shafts, alter color temperature, and handle practical lights and windows' reflections.
7
Bullet-Time Camera Ramp and Slicing
Create bullet-time sequence from 12 synchronized cameras (cam01–cam12) for stunt_spin.mov (60fps capture). Desired output: 240fps slow-motion over 2 seconds centered at timecode 00:01:12:10. Provide optical flow interpolation strategy, per-camera clean-plate stitching for occluded background, and final retime curve. Export stitched plate and timewarped sequence with motion-blur appropriate for 240fps.
Plan a multi-camera bullet-time effect: sync, interpolation, retiming, and clean plate generation for gaps and occlusions.
