Casual, conversational Hook-first : First line must stop the scroll — 1-2 seconds to capture attention Trend-aware : Reference trending sounds, formats, and cultural moments Value-driven : Every video must deliver on its promise Inclusive : Write for global audiences — simple English, avoid regional slang overuse Caption Templates Hook + Value + CTA: "POV: you just discovered [hack/trick/fact]" "Stop scrolling if you [pain point]" "3 things I wish I knew about [topic] sooner" "This [method] changed everything for me" "Nobody talks about this but [insight]" Story-driven: "I tried [X] for [time] — here's what happened" "Day [N] of [challenge/experiment]" "What I learned from [experience]" Engagement bait (compliant): "Save this for later" "Share with someone who needs this" "Comment [emoji] if you agree" "Which one are you? 1, 2, or 3?" Writing Rules DO: - Start with a hook (question, bold claim, or relatable scenario) - Use line breaks for readability - Include 1 clear CTA (follow, save, share, comment) - Write in first person where possible - Use numbers for specificity ("5 tips" > "some tips") - Match caption energy to video energy DON'T: - Start with "Hey guys" or "Welcome back" (wastes the hook) - Write walls of text (keep under 150 words in caption) - Use all caps excessively (looks spammy) - Promise what the video doesn't deliver (reduces retention) - Use banned/restricted words (see content-rules.md) - ⛔ Insert ANY external URLs in caption (GitHub, website, shop links, etc.) - ⛔ Put QR codes in video frames - External links ONLY allowed in Bio — use "Link in bio" to redirect Format Specs Video Specifications Item Spec Aspect Ratio 9:16 vertical (primary), 16:9 horizontal, 1:1 square Resolution 1080×1920 (vertical) / 1920×1080 (horizontal) Format MP4 / MOV / WebM Size ≤10GB (web upload), ≤287MB (mobile) Frame Rate 30fps (recommended) / 60fps Codec H.264 recommended Duration 15s — 10min (up to 60min for some accounts) Audio AAC, 44100Hz Duration Sweet Spots Duration Use Case Difficulty 7-15s Trending sounds, quick tips, memes ★ 15-60s Tutorials, storytelling, POV ★★ 1-3min In-depth how-to, reviews, vlogs ★★★ 3-10min Series content, full tutorials ★★★★ Cover Specifications Vertical Cover: 1080×1920 (9:16) - Full-screen display on profile grid - Primary cover format for most content Horizontal Cover: 1920×1080 (16:9) - Used for embed/share previews - Desktop browser display Design Rules: - Bold text overlay (3-5 words max) - High contrast colors - Face visible = higher CTR (+25-35%) - Bright, eye-catching backgrounds - Text safe zone: center 80% of frame Avoid: - Small/unreadable text - Cluttered designs - Logos without context - Black/dark backgrounds (blends with UI) Subtitle/Text Overlay Position: Center or lower third (avoid bottom 15% — UI overlay zone) Font: Bold sans-serif, white with black outline/shadow Size: ≥36pt (visible on mobile) Timing: Sync with speech, 1-2 lines max Style: Highlight keywords in accent color (yellow, red, green) Caption Rules TikTok 没有独立标题字段。 只有 Caption（描述文案），即发布时的文字输入区。Caption 兼具标题和正文功能，前 80 字符决定信息传达效率。不要在 Agent 调用中传递 title 参数。 Caption Writing Rule Detail Max Length 4,000 characters (as of 2025) Recommended 50-150 characters for best engagement Visible First ~80 characters before "more" truncation Keywords Place primary keyword in first 40 characters Line Breaks Use for readability — TikTok renders them Caption Formula [Hook line — grab attention] [Value/Content summary — 1-2 sentences] [CTA — follow, save, share, or comment prompt] [Hashtags — 3-5 relevant tags] Example Captions Tutorial: "The Excel trick your boss doesn't know about 👀 This saved me 3 hours every week.
