Execution Flow (Follow Exactly)

1. Parse args → extract video path/URL, options
2. Download remote video (if URL): yt-dlp "URL" -o /tmp/verging-video-enhancement/input.mp4
3. Get duration → ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 video.mp4
4. Trim if needed (--start/--end or duration > 30s):

   bash

   ffmpeg -i input.mp4 -ss <start> -to <end> -c:v libx264 -c:a aac /tmp/verging-video-enhancement/trimmed.mp4
   

5. Check credits → GET /api/v1/auth/me (need duration × 3 normal or ×5 HD)
6. Upload video → POST /upload-video (Form Data) → PUT to presigned URL
7. Create job → POST /video_enhance/create-job (Form Data)
8. Poll status → GET /jobs/list-jobs?job_ids=X every 5 seconds until COMPLETED
9. Return/download result → show result_url, optionally curl download

Critical Notes

• Use Authorization: ApiKey <key> (recommended) — Bearer <key> also works
• /upload-video uses Form Data (-F) — NOT JSON
• /video_enhance/create-job uses Form Data (-F) — NOT JSON, no file upload needed
• Max video duration: 30 seconds — trim longer videos first
• Temp directory: /tmp/verging-video-enhancement/
• If yt-dlp unavailable, ask user to download video manually
