Main ideas & lessons (cinematic AI workflow in SeaArt 2.5)

  • You need cinematic consistency across frames, not just “generate an image then a video.” Consistency comes from reusing the same camera/lens/look/color-correction references.
  • Use real cinematic references to guide mood, composition, and technical settings—especially for color and camera characteristics.
  • Scriptwriting is critical: the script must explicitly direct camera angles, timing, acting/performance nuances, and sound so the generation can follow it.
  • Iterative generation with structured prompts is the core method: break the video into chunks (e.g., ~30 seconds) and refine repeatedly using feedback.
  • Editing/post-production is where you finalize quality:
    • mine the best moments from multiple generations,
    • remove pauses/awkward acting beats,
    • align audio and add sound design, color tweaks, titles/subtitles.
  • Voice consistency is achieved by using a recorded audio sample as a reference so the model reuses the same “voice” pattern across generations.
  • Cost control and efficiency: generation is expensive, so you plan for mining/stitching and use tools to quickly find cut points.

Methodology / step-by-step workflow (detailed)

1) Build a reference library (Shotdeck + mood/emotion selection)

  • Go to Shotdeck to collect:
    • cinematic frame references (movies/commercials),
    • color correction / color codes (to replicate a look),
    • filming location clues,
    • camera and lens data (camera model, lenses, lighting info),
    • film type and other metadata.
  • Practical usage:
    • Choose references that match the emotion/mood you want (comedy vs serious, etc.).
    • Treat the feed like a “training tape”:
      • identify frames that “catch attention” (often lighting + saturation + composition),
      • note the emotion the character conveys (the scene should prompt curiosity, not just look pretty).
  • Save:
    • screenshots of frames and their metadata,
    • color correction references and related scenes.
  • Optional planning tool:
    • collect everything into a moodboard tool (mentioned: Milanote).

2) Reverse-engineer a shot into Midjourney/Claude prompts

  • Select a reference frame/video and create your own version:
    • Screenshot the frame you want.
  • In Midjourney:
    • Upload the screenshot as an image prompt/style reference.
    • Place it into:
      • style reference and image prompt sections.
  • In Claude:
    • Start a new chat and upload the frame + metadata (from Shotdeck).
    • Ask Claude to write a Midjourney prompt that recreates the same cinematic style, including:
      • camera body + lens information,
      • the look/lighting/composition.
  • Use Claude-generated lens/camera tokens inside Midjourney to lock style.
  • Refinements:
    • In Midjourney, you can edit an image by describing what to remove/add (e.g., delete characters, add foreground elements).
    • If you want more uniqueness than copying composition:
      • generate new variations using prompt iteration rather than strict copy.

3) Increase variation strategically (Midjourney “weirdness/variety”)

  • Adjust settings such as:
    • increase weirdness and/or variety.
  • Goal:
    • get multiple options per batch (e.g., 4 shots) that are more diverse.
  • Then select the best location references and optionally upscale/zoom for quality.

4) Write a screenplay that explicitly directs acting + technical details (Claude-assisted)

  • Scriptwriting mindset:
    • The hardest part for most people is that you must “see it” internally.
    • It determines success/failure more than expected.
  • Use prompts/templates:
    • Claude helps convert a detailed directing script into a usable prompt.
  • Screenwriting format (how you direct):
    • Specify shot type and viewpoint (e.g., wide shot from bird’s-eye view, matching the reference angle).
    • Specify timing (e.g., “camera lingers for 2 seconds”).
    • Specify audio (e.g., park atmosphere, faint birdsong).
    • Specify acting/performance nuances (crucial lesson):
      • eyebrows, head tilt, eye “game,” lip tremble, shoulders slumping, etc.
    • Specify physical actions precisely (e.g., phone thrown onto grass to match sound).
    • Specify voice/character traits for consistency (e.g., accent and delivery style).
  • Build the story using a clear message/metaphor:
    • Example message: dislike of AI agents in creativity; wants struggle/challenge.
    • Conveyed via metaphor: a Tamagotchi-like object (“pixel friend”).

5) Create character sheets & prop/location references (GPT Image 2 + Claude + ArtCraft/SeaArt flow)

  • Character sheets:
    • Use GPT Image 2 to generate photoreal character sheets.
    • Create custom characters by adding:
      • a face photo of yourself,
      • style elements (t-shirts, crocs, etc.).
  • Props (and copyright workaround):
    • If a desired branded item gets blocked:
      • rename/replace it in the reference (e.g., “Tamagotchi” → “Pixel Pal” / “pixel friend”).
    • If the model still adds forbidden text:
      • add prompt instructions like “Don’t mention the word X.”
  • Location references:
    • Use Midjourney-created environments plus saved Shotdeck color/camera metadata.
  • Platform note:
    • The speaker uses ArtCraft (described as fewer restrictions than alternatives).

6) Generate prompts in Claude, then generate in SeaArt 2.5 / ArtCraft

  • Inputs to Claude:
    • references (character sheet(s), location, props),
    • cinematic reference,
    • the entire script.
  • Prompt constraints:
    • SeaArt request max: 10,000 characters.
    • If the script doesn’t fit the intended runtime:
      • split into multiple chunks to preserve detail.
  • Install a Claude skill:
    • speaker mentions a custom Claude “video request builder” skill to improve formatting.

7) Handle runtime limits by splitting into multiple requests

  • Problem encountered:
    • One generation prompt became “haywire” because output exceeded 30 seconds.
  • Fix:
    • split the story into two 30-second requests (or add buffers),
    • ensure each chunk has full detail, then merge later.

8) “Mining” + continuity strategy (edit multiple generations)

  • Mining definition (speaker’s term):
    • extract the best moments from multiple generated clips.
  • Continuity lesson:
    • 30-second generations help preserve:
      • character placement continuity between cuts,
      • acting continuity.
    • Short isolated clips can shift character positions due to lack of context.
  • Fixing mistakes mid-iteration:
    • when continuity fails (example: falling off bench improperly),
    • analyze the unwanted segment,
    • return to Claude with specific feedback (timing, camera switch, eyebrow timing, wide vs close-up, leg crossing, laugh timing, etc.),
    • regenerate with the refined prompt.
  • Stitching final sequence:
    • take best shot portions from different generations and assemble into one narrative.

9) Faster cut selection in Premiere Pro (scene edit detection)

  • In Premiere Pro:
    • Right-click the clip → Scene Edit Detection
    • choose “create clip marker at each detected cut point”
    • use markers to quickly pick best segments for mining/stitching.

10) Add voice consistency using an audio-reference sample

  • Create a voice reference:
    • speaker records themselves speaking a sentence designed to cover many phonemes (pangram-like).
  • Use that reference:
    • load as a video reference (black MP4 recommended) + audio sample,
    • export audio from your editor and import it as audio reference.
  • Add to prompts:
    • instruct Claude/requests to use the recorded voice sample consistently for “person A.”
  • Important consequence:
    • voice remains locked across generations even if visual placement varies slightly.

11) Post-production assembly (Premiere Pro workflow)

  • Assembly goals:
    • social media pacing: start action early,
    • remove pauses and dead air,
    • sync audio with best visual takes.
  • Example post steps:
    • move audio start earlier so dialogue matches the opening clip,
    • cut on key lines (e.g., start throwing phone away right when the line occurs),
    • montage the best acting beats to avoid awkward silence.
  • Sound design:
    • add targeted effects aligned with visuals (e.g., zoom/impact effect when camera zooms).
  • Color finishing:
    • apply Lumetri color adjustments consistently across all clips:
      • saturation, exposure, temperature.
    • optional: use DaVinci Resolve for deeper grading (speaker mainly uses Lumetri tweaks).

12) Music and sound assets (Artlist + Suno) and synchronization with script tempo

  • Use Artlist for:
    • stock sound effects,
    • music (and also mentions AI music tools).
  • Use Suno for:
    • generating original music quickly.
  • Claude’s role in music timing:
    • Claude can interpret timecodes/structure from prompts,
    • create music prompts aligned to script rhythm (tempo, key, piano, slow BPM).
  • Add subtitles for silent viewing:
    • simple subtitle overlays in your video editor.

Outcome claim / key takeaways (what the video wants you to believe)

  • Following this pipeline enables creation of cinematic AI videos end-to-end, including:
    • script, references, generation, voice consistency, and polished post-production.
  • The speaker claims competence can lead to charging $5,000–$50,000 for AI projects (marketing claim).
  • The process is framed as “textbook-missing” real problem-solving plus iterative correction.
