In order to realize \"Character Consistency\", we need to combine technical means, creation strategies and tools, and the following are the key methods and practical suggestions.<\/p>\n<p>We can understand \"role alignment\" on two levels:<\/p>\n<p><strong>I. Meaning of role coherence<\/strong><\/p>\n<p>Role consistency has two main aspects:<\/p>\n<ul>\n<li>Visual consistency: features such as face shape, facial features, hairstyle, clothing, skin color, and makeup remain stable;<\/li>\n<li>Behavioral consistency: character, action habits, expression style, etc. to be consistent, not the first act of cold overbearing total, the second act suddenly become soft and cute teenagers.<\/li>\n<\/ul>\n<blockquote>\n<ul>\n<li>\ud83c\udfaf Why is it important?<\/li>\n<li>If the characters constantly \"change their faces\", the audience will feel out of the scene, jumping, unprofessional, affecting the sense of immersion in the plot.<\/li>\n<\/ul>\n<\/blockquote>\n<p><strong>Second, how can AI realize \"characters from beginning to end without changing faces\"?<\/strong><\/p>\n<p><strong>Method 1: Setting up a unified character archetype + extracting feature tags<\/strong><\/p>\n<ul>\n<li>In the early stages of creation, start with an image generation model (e.g. Midjourney, DALL-E) and fix a [character avatar image];<\/li>\n<li>Then from this image, the character's features such as facial features, hairstyle, expression, and clothing are extracted as style tag keywords;<\/li>\n<li>All subsequent generation references this set of keywords or diagrams.<\/li>\n<\/ul>\n<p>\ud83d\udccc Example cue word (graphic organizer):<\/p>\n<p>Upload a picture of the character + prompt: photo of a cold and elegant businesswoman, long black hair, sharp eyes, white suit, cinematic lighting, in an office<\/p>\n<p><img

2: Use of AI role consistency models (e.g. Vidu, Veo, Runway role bindings)<\/strong><\/p>\n<p>Many AI video platforms now support role consistency features, for example:<\/p>\n<table>\n<thead>\n<tr>\n<th data-colwidth=\"186\">\n<section>platform<\/section>\n<\/th>\n<th>\n<section>Role Coherence

that you enter a character fixation map at the first frame or keyframe to serve as a consistent anchor point for subsequent video characters.<\/p>\n<p><strong>Method 3: Use ControlNet face consistency module (e.g. IP-Adapter + LoRA + faceid)<\/strong><\/p>\n<p>If you use Stable Diffusion or a similar AI image generation tool, you can achieve face consistency this way:<\/p>\n<ul>\n<li>IP-Adapter: allows to \"import\" image styles\/face features into the model;<\/li>\n<li>LoRA weighting model: training a particular character;<\/li>\n<li>faceid\/clip-vision: compare and analyze subsequent generated graphs for consistency and reverse control.<\/li>\n<\/ul>\n<p>\ud83d\udccc Midjourney doesn't support direct \"face lock\", but you can lock your character's appearance with Seed + prompt.<\/p>\n<p>Method 4: Build a \"Role Thesaurus\" + Set up a Unified Prompt Word Template<\/p>\n<p>Unify definitions when writing scripts and coming up with subplots with AI:<\/p>\n<ul>\n<li>Keywords for the main character's appearance (gender, hairstyle, clothing, race, etc.);<\/li>\n<li>Emotional keywords (cold, strong, gentle, etc.);<\/li>\n<li>Common appearance scenes (office, street, stage, etc.);<\/li>\n<\/ul>\n<p>\ud83d\udccc Example Role Template:<\/p>\n<ul>\n<li>Character Name: Lin Evening<\/li>\n<li>Appearance Keywords: long black hair, pale skin, cold beauty, red lips<\/li>\n<li>Emotional keywords: calm, resolute, unsmiling<\/li>\n<li>Common scenarios: nighttime city, under office lights, walking alone in the rain<\/li>\n<\/ul>\n<p>Method V:<strong>Targeting Character Traits Using Reference Maps<\/strong><\/p>\n<p>This is the most direct and effective method, by providing a reference image of the character, based on which the AI generates consistent features such as face, hairstyle and clothing.<\/p>\n<p><strong>Specific operations:<\/strong><\/p>\n<p><strong>(i) Midjourney (cref function)<\/strong>:<\/p>\n<p><strong>1. Generate a reference picture: first generate a standard image of the character (e.g., frontal, clear face) using the cue words.<\/strong><\/p>\n<p><strong>2. use \u2013cref parameters: add \u2013cref in subsequent generation<\/strong>And a link to the reference image.<\/p>\n<ul>\n<li>syntax: \u2013clef [reference link] \u2013cw [weight]<\/li>\n<li>weight (-cw)<\/li>\n<\/ul>\n<p>\u2013cw 100: strict maintenance of the face, hair, clothing\u3002<\/p>\n<p>\u2013cw 0: only face, with hair, clothing\u3002<\/p>\n<p>3. Adjust the scene: modify the descriptors for background, action, etc., but keep the character traits.<\/p>\n<p>An example of a woman with long black hair, moving towards the Camera, heading a red dress in a park<\/p>\n<p>(ii) i.e. Dream AI (Character trait locking):<\/p>\n<ul>\n<li>Generate Multi-Role Pad Chart: Mr. Generate a reference chart containing multiple roles (e.g., a family portrait).<\/li>\n<li>Importing reference drawings: In the subsequent generation, select the \"Characterization\" mode and import the mat drawings.<\/li>\n<li>Adjustment of cue words: modify scene descriptions (e.g., background, action), but keep character trait keywords.<\/li>\n<\/ul>\n<p><strong>III.
