Video Cover Image
Overview
Create a matched three-cover set for one technical short-video script:
- Vertical cover:
3:4, for 小红书、抖音、快手 and mobile feeds. - Widescreen cover:
16:9, for B站 and standard widescreen video thumbnails. - Standard horizontal cover:
4:3, for platforms or placements that prefer a less-wide thumbnail.
By default, generate all three covers as one matched set. Generate fewer ratios only when the user explicitly says only/只要/单独生成 specific ratios.
Use the itwanger-image style rules when available. Keep prompt context isolated: use only the target script, user-provided reference images, and this skill's rules. Do not pull in unrelated browser/editor/window/history content.
If the user provides a reference image or asks for 纯文本, 白色大字+黄色小字, 黑色/黑灰背景, or 参考图这种布局, use the pure-text reference style below instead of the default illustrated style. Use deterministic rendering for this mode so Chinese text stays exact.
For video covers, do not add copyright signatures, watermarks, corner marks, or small ©️沉默王二 labels unless the user explicitly asks for them. This cover-specific rule overrides any lower-level image-skill signature preference.
