😰 Nỗi đau của doanh nghiệp
Việc tạo và xuất bản video lên YouTube đang đối mặt với nhiều thách thức:
- Scriptwriting, editing, publishing disconnected: Traditional workflow yêu cầu: writer tạo script → pass cho video editor → editor làm video trong Premiere/After Effects (nhiều giờ) → export → manually upload lên YouTube với title/description/tags. Mỗi stage có handoffs và delays, total timeline 2-3 ngày per video.
- Quality varies widely: Khi nhiều editors work trên different videos, quality inconsistent: some videos có great pacing và visuals, others mediocre. Brand identity và viewer experience bị ảnh hưởng.
- Modern AI có thể standardize: AI video generation tools (Runway, Pika, MagicVideo) có thể tạo consistent-quality videos từ text prompts. Tuy nhiên, chưa có workflow tích hợp end-to-end từ idea → published video.
- YouTube upload API complexity: YouTube Data API v3 yêu cầu OAuth authentication, proper video metadata formatting, thumbnail handling, và error management. Nhiều teams không có technical expertise để automate uploads.
🎯 Vấn đề cần ưu tiên xử lý
Để giải quyết các nỗi đau trên, doanh nghiệp cần tập trung vào các vấn đề then chốt:
- Chuẩn hóa inputs qua Google Sheets: Marketing team nhập video ideas vào Sheets với fields: title, core message, target duration (30-90s), number of scenes (3-5), visual style preference. Simple spreadsheet interface → no video expertise needed.
- GPT-4o cho screenplay generation: AI reads Sheets row, generates detailed screenplay: scene-by-scene breakdown, visual descriptions, text overlays, transitions, pacing notes. Transform simple idea thành production-ready script.
- MagicVideo-V2 (hoặc Runway) rendering: Each scene's description được send đến AI video generator. Generates 5-second clips với consistent style, good pacing, và relevant visuals. Clips automatically downloaded và queued.
- YouTube Data API integration: After video assembly, automatically upload với proper metadata: optimized title, SEO-friendly description, relevant tags, custom thumbnail. Handle OAuth flow và rate limits gracefully.
- Quality checkpoints: Validation at key stages: screenplay review (optional human approval), video preview before upload, post-upload verification. Catch issues trước khi going live.
⚙️ Quy trình chi tiết thực hiện
Bước 1 — Google Sheets trigger cho video ideas
Marketing team nhập video ideas vào designated Sheets: Title (hook-driven), Core message (1-2 sentences), Duration (30/60/90s), Scenes (3-5), Style (professional/casual/energetic), Target audience, CTA. New row triggers n8n workflow automatically.
Input fields: Title, Core message, Duration, Scene count, Visual style, Target audience, CTA, Priority, Status
Bước 2 — GPT-4o generates detailed screenplay
AI reads video brief và creates scene-by-scene screenplay: Scene 1 (0-5s): Opening hook visual, text overlay, voiceover script. Scene 2 (5-10s): Problem illustration, transition note. Etc. Screenplay includes: visual descriptions, text overlays, pacing cues, transition effects, music mood suggestions.
Screenplay elements: Scene breakdowns, Visual descriptions, Text overlays, Voiceover scripts, Transitions, Music cues, Pacing notes
Bước 3 — Normalize prompts cho video generation
Screenplay được parsed và normalized thành video generation prompts. Mỗi scene's description + style preferences → structured prompt cho AI video model. Ensure consistency: same style keywords, camera angles, lighting across scenes. Add technical parameters: resolution (1920×1080), duration per clip (5s), frame rate (30fps).
Prompt structure: Visual description, Style keywords, Camera angle, Lighting, Duration, Technical specs, Negative prompts
Bước 4 — Render video clips với MagicVideo-V2
Mỗi scene prompt được send đến MagicVideo-V2 API (hoặc Runway Gen-2, Pika). Generate 5-second video clips với consistent quality. Poll for completion (typical 2-5 phút per clip), download when ready. Process multiple scenes in parallel để speed up.
Generation settings: Model (MagicVideo-V2), Resolution (1080p), Duration (5s per clip), Style consistency params, Batch processing
Bước 5 — Add background music và audio
Select royalty-free music từ library (based on mood từ screenplay: upbeat, calm, dramatic). Add voiceover if scripted (using ElevenLabs hoặc similar TTS). Mix audio levels: music at -20dB background, voiceover at 0dB foreground, smooth fade in/out.
Audio elements: Background music selection, Voiceover generation (TTS), Audio mixing/levels, Fade effects, Sync with video timing
Bước 6 — Assemble final video với FFmpeg
Use FFmpeg (powerful video processing tool) để: concatenate all scene clips, add text overlays tại timestamps specified, apply transitions between scenes, mix audio tracks, render final video at 1080p 30fps. Export as MP4 H.264 format (YouTube optimal).
FFmpeg operations: Concatenate clips, Add text overlays, Apply transitions, Mix audio, Color correction, Export MP4 H.264
Bước 7 — Generate metadata và thumbnail
GPT-4o creates YouTube-optimized metadata: Title (with keywords, <60 chars), Description (with timestamps, links, CTAs, 200-300 words), Tags (15-20 relevant keywords), Category selection. DALL-E hoặc Midjourney generates eye-catching thumbnail based on video content.
Metadata: Optimized title, SEO description, Relevant tags, Category, Playlist assignment, Thumbnail design
Bước 8 — Upload qua YouTube Data API
Authenticate với YouTube API using OAuth 2.0 (pre-configured credentials). Upload video file với multipart upload (for large files), set metadata (title, description, tags, category), upload custom thumbnail, set privacy status (public/unlisted/private), assign to playlist. Handle rate limits và retry logic.
API operations: OAuth authentication, Video upload (multipart), Metadata setting, Thumbnail upload, Privacy/publish settings, Playlist assignment
Bước 9 — Monitor status và log results
After upload, poll YouTube API for processing status. Once video live, capture: Video ID, URL, upload timestamp, processing duration. Update Google Sheets với: Status (Published), YouTube URL, Analytics link. Send notification qua Slack/email với video link để team review.
Monitoring: Upload status, Processing completion, Video URL, View count tracking, Error logging, Team notifications
