Seedance 2.5 Tutorial: Cinematic AI Video From Start To Finish
Main summary
Key takeaways
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.”
- If a desired branded item gets blocked:
- 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.
- 30-second generations help preserve:
- 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).
- apply Lumetri color adjustments consistently across all clips:
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)
