Fast Clean‑Up: Remove Objects and Swap Wardrobe




Key Takeaway: Replace hours of roto with a prompt and a short render.


Claim: Multi‑agent processing handles object detection, temporal inpainting, lighting match, and seam blending.


  • Use Edit by Prompt to remove unwanted elements without manual masks.


  • Wardrobe swaps preserve fabric folds, texture, and motion.


  • Select the target clip on your timeline.

  • Click Edit by Prompt.

  • Enter a clear instruction, e.g., “remove the car behind me.”

  • Generate and let the Agent process the sequence.


  • Drag the output back to the timeline; check for clean edges and no flicker.


  • For clothing, select the person region via Mask or Draw Area.

  • Prompt: “change outfit to striped pajamas, keep natural folds and shadows.”

  • Generate and preview the garment movement through the shot.

  • Replace the clip on your timeline if it matches your look.

Background Replacement That Belongs in the Scene




Key Takeaway: Swap environments while matching grade, exposure, and motion.


Claim: Per‑frame processing with temporal smoothing reduces the pasted‑on feel.



  • Replace a background plate and keep your subject naturally integrated.


  • Select the clip that needs an environment change.

  • Prompt: “replace background behind the person with a warm sunset view from a hill, add subtle lens flare.”

  • Generate to let the Agent extend the horizon and color‑match the subject.

  • Review for consistent lighting and absence of jitter.

  • Insert the output into your timeline and adjust overall grade as needed.

Add Characters and Design Transitions




Key Takeaway: Insert believable passersby and cinematic transitions without reshoots.


Claim: Character synthesis can match scene lighting and camera motion using a reference image and brief notes.


  • Add an older version of yourself or a styled extra to support story beats.


  • Build whip‑pan or zoom transitions from start/end frames by prompt.


  • Attach a face or look reference for the character.

  • Prompt: “add an older me walking past from left to right.”

  • Optionally include a short character sheet: voice style, outfit, gait.

  • Generate and confirm lighting and camera motion coherence.


  • Drop the result into the timeline where the beat lands.


  • Open Video Generation for transitions.

  • Provide start and end frames from the adjacent clips.

  • Prompt: “create a dynamic whip‑pan to zoom transition with match‑cut and motion blur.”

  • Generate and audition variants for pacing and style.

  • Insert between clips to finalize the cut flow.

Alternate Angles and Social Reframes




Key Takeaway: Synthesize plausible angles and auto‑recompose for platforms.


Claim: Angle‑aware synthesis renders new passes with consistent lighting and parallax.



  • Create variety from a single setup and produce vertical or cinematic crops fast.


  • Prompt: “create two alternate camera angles: one from the left medium close, one low angle with slight tilt.”

  • Generate and review framing, FOV, and realism.


  • Pick the angle that reads as natural and insert as a cutaway or alt take.


  • Click Reframe for format changes.

  • Choose 9:16, 4:3, or 21:9 and generate three options.

  • Nudge the crop or prompt, e.g., “make the subject slightly left framed,” then regenerate.

  • Approve the version with safe margins for captions.

Rescue Footage: Upscale, Cutaways, and Audio Polish




Key Takeaway: Upgrade old clips and cover edit gaps without leaving the timeline.


Claim: Denoise, stabilization, and upsampling preserve skin tones and grain character.


  • Patch missing shots with synthetic cutaways that match color and motion.


  • Clean dialogue, remove echo, and auto‑duck music; generate VO if needed.


  • For old phone clips, open Upscale.

  • Choose the target resolution; no prompt required.

  • Generate to apply denoise, stabilization, and upsample.


  • Replace the original in your sequence.


  • Missing B‑roll? Prompt: “generate a 5‑second cutaway of a city street at golden hour, handheld vibe, shallow depth.”

  • Generate and check match to project color and motion.


  • Place it to cover jumps or tighten pacing.


  • For audio, prompt: “clean dialogue, remove room echo, add gentle ambiance, and duck music during speech.”

  • Generate to run spectral cleaning, EQ, and compression.

  • Optionally prompt for VO, e.g., “friendly, slightly sarcastic, 30s promo VO,” then audition takes.

  • Drop in chosen VO and rebalance levels.

One‑Prompt Assembly with Agent Director




Key Takeaway: Turn a folder of clips into a draft story with one instruction.


Claim: The Agent can assemble selects, trim beats, add music/SFX, grade, and propose captions.



  • Start with a creative brief and get an editable timeline draft.


  • Open the Agent Director flow.

  • Prompt: “Turn this raw folder into a 60‑second product story: punchy cuts, upbeat indie music, color grade to teal‑orange, subtitles, and two motion transitions.”

  • Generate to assemble, trim, score, grade, and caption.

  • Review the draft and tweak beats, transitions, or grade to taste.

Signature Effect: The Time‑Slice Trick




Key Takeaway: Create a day‑to‑night time‑slice pass that feels like a mini music video.


Claim: Multi‑layer compositing can shift background time while preserving subject exposure.



  • Combine synthesized backgrounds, light particles, and glassy reflections.


  • Select the office shot you want to stylize.

  • Prompt: “create a 10‑second time‑slice where the background shifts from morning to neon night while I walk through it, add streaking light particles and subtle glass reflections.”

  • Generate to build layered composites and matched exposure.

  • Accept the suggested swooping transition into the next scene or refine it.

When to Use It vs. Other AI Editors




Key Takeaway: Use prompt‑first tools grounded in real footage when integration beats pure generation.


Claim: A multi‑agent pipeline that talks across tasks reduces handoffs and re‑exports.


  • Some tools excel at pure scene generation but falter on messy, real‑world clips.


  • Others are strong at single tasks yet require manual touch for the rest.


  • Choose this approach when you must match on‑set lighting, motion blur, and occlusions.

  • Prefer it for timeline‑native edits that avoid export/import loops.

  • Use pure generators when you need a fully synthetic scene from scratch.

  • Mix both when a synthetic cutaway complements real footage.

Practical Notes and Limits




Key Takeaway: Prompts are iterative; realism comes from clear intent and small adjustments.


Claim: Basic prompts usually reach 80% quality; minor tweaks align style and naturalism.


  • Ask for “more natural render” to tone down stylization or add “film grain” and “2.35:1 crop” for cinematic looks.


  • Expect occasional manual cleanup on complex occlusions or fast strobe motion.


  • Start with a simple, literal prompt; generate a baseline.

  • Nudge specifics: fabric type, framing bias, motion strength.

  • Regenerate with minimal changes to isolate improvements.

  • For tricky shots, mask critical regions and run a targeted pass.
