Auto Cinematic Image Generator Skill
Purpose
This skill converts 1–5 reference images into production-ready prompts for GPT Image 2 style image generation workflows. It is designed for cinematic, fashion, beauty, portrait, editorial, contact-sheet, storyboard, and video keyframe generation while preserving the reference subject, wardrobe, styling, lighting, color grade, and environment with strict continuity.
Use this skill when the user wants any of the following:
- a single cinematic portrait from a reference image
- a vertical 9:16 portrait, horizontal 16:9 frame, square 1:1 image, or 2:3 fashion still
- a batch of alternate camera angles generated as separate images
- a 2×3 or 3×3 contact sheet containing multiple poses / camera angles in one image
- macro close-ups of facial features, fabric texture, neckline, hair, makeup, accessories, hands, shoes, or set details
- start frame and stop frame pairs for video generation
- consistent cinematic variations based on 1–5 reference images
Core rule
The reference image is always the ground truth. Preserve the subject identity, body proportions, facial structure, hair, makeup, wardrobe, fabric material, colors, accessories, environment, lighting direction, shadow quality, color grade, and photographic style unless the user explicitly requests a change.
Do not add props, jewelry, glasses, extra people, creatures, objects, logos, text, furniture, scenery, or accessories unless they are visible in the reference or explicitly requested.
Reference image roles
The skill supports 1–5 images. Assign roles internally:
primary_identity: face, body type, hair, makeup, skin tone, expression, subject identity.wardrobe_material: clothing silhouette, textile, stitching, texture, reflectivity, accessories, shoes.lighting_colorgrade: lighting direction, contrast, film look, grain, exposure, color palette.pose_composition: pose, body language, camera crop, framing, lens character.environment_set: background, set geometry, surface texture, props, spatial depth.
When only one image is provided, infer missing information conservatively and consistently. Never invent fashion-critical details beyond what is needed for the selected shot type.
Generation modes
1. single_cinematic_portrait
Generate one image. Best for 9:16, 16:9, 1:1, or 2:3 portraits. Can be close-up, medium, full-body, macro detail, profile, low-angle, high-angle, or editorial fashion portrait.
2. cinematic_variation_pack
Generate multiple separate prompts for separate images. Each prompt is one alternate camera placement from the same scene. Useful for 2:3 cinematic image sets, pose exploration, and client selects.
3. contact_sheet_2x3
Generate one image containing exactly six frames in a 2×3 grid. Each frame must share the same subject, wardrobe, lighting, color grade, environment, and style.
4. angle_grid_3x3
Generate one image containing nine frames in a 3×3 grid. Default order: MCU, MS, OS, WS, HA, LA, P, ThreeQ, B.
5. macro_detail_pack
Generate close-up studies of fabric, eyes, lips, hair, neckline, straps, hands, shoes, jewelry, closures, texture, stitching, or skin highlights. Do not create details not present in the references.
6. video_start_stop_frames
Generate a matched start frame and stop frame pair for video workflows. The frames must look like the same subject and scene at two clearly different resting points. Describe only final positions, not motion.
7. storyboard_sequence
Generate sequential cinematic keyframes with strict continuity. Useful for videos, commercials, fashion campaigns, beauty reels, and scene previsualization.
8. custom_shot_list
Use a user-defined shot list. Preserve all continuity rules and output either separate prompts or one contact sheet.
Default cinematic shot vocabulary
- Macro Close-Up: extreme crop on eyes, lips, skin, texture, fabric, hair, strap, or accessory.
- Beauty Close-Up: head-and-shoulders, shallow depth of field, sculptural face lighting.
- Medium Shot: chest-up or waist-up portrait.
- Medium-Wide: hips or upper thighs visible.
- Full Body: complete outfit and posture visible.
- Wide Shot: subject in relationship to environment.
- High Angle: camera physically above, looking down.
- Low Angle: camera physically below, looking up.
- Profile: strict side view, 90 degrees.
- Three-Quarter: subject turned roughly 45 degrees from camera.
- Back View: directly behind the subject.
- Over-Shoulder: a blurred foreground shoulder or edge from the same scene; do not add another person.
- Oblique: diagonal camera placement with dynamic perspective.
- Long Lens Compression: flattened editorial profile or near-profile.
- Detail Insert: close focus on textile, closure, strap, shoe, hair, makeup, or set texture.
Style presets
reference_locked
Copy lighting, color grade, exposure, lens feel, and retouching from the reference as closely as possible.
soft_beauty_studio
Large diffused key light near camera axis, soft shadows, smooth skin, polished beauty retouch, shallow-to-moderate depth of field.
hard_flash_fuji_velvia
Fuji Velvia-inspired oversaturated color, direct hard flash, concentrated subject illumination, falloff toward edges, overexposed highlights, visible film grain, shiny skin highlights, strong satin or glass reflections when present.
cinematic_editorial
Fashion/editorial composition, controlled contrast, natural lens compression, intentional depth of field, polished but realistic textures.
warm_orange_studio
Warm amber/orange palette, seamless studio backdrop, gold/copper highlights, soft-to-medium contrast, commercial portrait finish.
Contact sheet rules
For contact sheets, output a single image with clean borders, consistent grading, and readable labels. Every panel must show the same subject and same scene continuity. Panel labels should be concise. Optional captions should describe only the final camera position and subject action.
Video start/stop frame rules
A start frame and stop frame must preserve identical subject identity, wardrobe, hair, makeup, materials, lighting, environment, shadow quality, photographic style, and color grade.
The start and stop frames must not be visually identical or near-duplicates. Treat identical keyframes as invalid output. They must differ in at least two visible axes, for example camera angle plus framing distance, camera height plus subject pose, profile versus frontal view, wide full-body versus close portrait, or macro detail versus portrait. Safe difference axes are camera angle, camera height, camera side, framing distance, composition, lens feel, subject resting pose, body orientation, gaze direction, hand position, head angle, focus target, and depth of field.
Never solve video continuity by copying the same still twice. Never describe movement blur unless requested. Describe final resting states only.
Start/stop frame anti-duplicate checklist
Before finalizing any video_start_stop_frames output, verify:
- Start and Stop have the same identity, wardrobe, hair, makeup, lighting, environment, and color grade.
- Start and Stop differ in at least two visible axes.
- The prompt explicitly names the difference, such as “Start: eye-level medium shot, subject facing camera” and “Stop: high-angle close portrait, subject turned three-quarter with gaze slightly off-camera.”
- The output contains a
start_stop_delta_summary.
- If the model still produces duplicates, switch seed strategy from
same_seed_for_continuity to paired_seed_for_video_keyframes or different_seed_per_variation, while keeping the same reference image and continuity locks.
Prompt construction order
- Reference grounding statement.
- Continuity lock: identity, wardrobe, hair, makeup, accessories, body proportions, environment, lighting, color grade.
- Mode description: single image, separate prompts, contact sheet, grid, detail pack, or video frames.
- Camera and composition instructions.
- Style and technical rendering instructions.
- Negative constraints.
- Output format instructions.
Negative constraints baseline
Do not add extra people, props, furniture, jewelry, glasses, logos, text, tattoos, hats, bags, scenery, creatures, or objects. Do not change garment type, fabric, color, silhouette, strap placement, stitching, hair length, makeup, face, body proportions, background, lighting direction, or color grade. Do not stylize away from photorealism. Do not reinterpret the wardrobe material.
Recommended aspect ratios
9:16: vertical portrait, social video frame, fashion reel keyframe.16:9: cinematic landscape, storyboard, 3×3 grid, video start/stop frame.1:1: square portrait, compact contact sheet, profile image, product-style detail set.2:3: editorial fashion still, portrait campaign, cinematic still set.3:2: horizontal photo still.4:5: social editorial portrait.
Output expectations
The skill can return:
- one final prompt
- multiple prompts for separate generations
- one contact sheet prompt
- a keyframe breakdown
- a start/stop frame pair
- a continuity checklist
- negative prompt constraints
When generating prompts, keep them technically explicit, visually grounded, and concise enough to be usable directly with an image model.
