1. Introduction

RedGifs is a short-form media host that serves MP4 clips and GIF variants through a tokenized API. The platform relies on an authentication token to query media metadata and returns direct CDN URLs for playback.

1.1 Research Scope

  • RedGifs watch and iframe pages
  • Temporary token API endpoints
  • MP4/GIF URL variants and m4s segments
  • CDN hostnames and URL patterns

1.2 Methodology

  • Inspect token generation and API responses
  • Capture direct media requests from network logs
  • Validate URLs with yt-dlp and ffprobe

2. RedGifs Video Infrastructure Overview

2.1 Video Hosting Types

  • API-driven MP4 and GIF delivery
  • fMP4 segments served as .m4s
  • Direct MP4 files hosted on thumbnail CDN

2.2 CDN Architecture

  • api.redgifs.com (token + metadata)
  • thumbs2.redgifs.com (MP4/GIF assets)
  • media.redgifs.com (segments and alternate encodes)

2.3 Video Processing Pipeline

  1. User loads watch/iframe page
  2. Client requests temporary token from /v2/auth/temporary
  3. Client queries /v2/gifs/ with Bearer token
  4. Client fetches direct MP4/GIF from CDN

2.4 Access Control and Authentication

  • Bearer token required for API requests
  • Tokens expire quickly; refresh when needed
  • Referer/Origin headers may be checked

3. URL Patterns and Detection

3.1 Watch Page URL Patterns

https://www.redgifs.com/watch/<id>
https://www.redgifs.com/ifr/<id>

3.2 Embed URL Patterns

https://www.redgifs.com/ifr/<id>

3.3 Direct Media and CDN URL Patterns

https://thumbs2.redgifs.com/<Name>.mp4
https://thumbs2.redgifs.com/<Name>.gif
https://media.redgifs.com/<Name>.m4s

3.4 Regex Patterns for URL Extraction

redgifs\\.com/(?:watch|ifr)/([^/?#]+)
thumbs2\\.redgifs\\.com/([^/?#]+)\\.(mp4|gif)

3.5 Command-line URL Extraction

grep -oE "https?://[^'\" ]+\.(mp4|gif|m4s)" page.html | sort -u
grep -oE "redgifs\\.com/(watch|ifr)/[A-Za-z0-9-]+" page.html | sort -u

4. Stream Formats and CDN Analysis

4.1 Stream Formats

Format Extension Notes
MP4 (progressive) .mp4 Direct file URLs hosted on thumbs CDN
GIF .gif Animated GIF variants for quick previews
fMP4 segments .m4s Segmented assets referenced by playlists

4.2 Typical Quality Ladder

Quality Typical Resolution Notes
Low 360p - 480p Fast preview streams or mobile variants
Medium 720p Common default for web playback
High 1080p+ Available when source uploads are higher quality

4.3 CDN URL Construction and Query Parameters

  • API returns multiple URL fields for different encodes
  • Filename variants often include size or mobile indicators
  • Signed tokens are short-lived

4.4 Validation and Inspection Commands

ffprobe -hide_banner -show_streams "clip.mp4"
ffprobe -hide_banner -show_format "clip.mp4"

5. yt-dlp Implementation Strategies

yt-dlp works well for direct MP4 URLs and can ingest the watch page URL when the extractor resolves the API flow. Use cookies and headers if the API enforces origin checks.

5.1 Basic Usage

yt-dlp [OPTIONS] [--] URL [URL...]
yt-dlp -F "https://example.com/watch/123"

5.2 Authentication and Cookies

  • Use --add-header 'Referer: https://www.redgifs.com/' when direct URLs are gated
  • If using the API directly, pass the Bearer token in headers

5.3 Format Selection and Output Templates

yt-dlp -f bestvideo+bestaudio/best "URL"
yt-dlp -o "%(title)s.%(ext)s" "URL"
yt-dlp --download-archive archive.txt "URL"

5.4 Site-Specific Examples

yt-dlp "https://www.redgifs.com/watch/<id>"
yt-dlp -f best "https://www.redgifs.com/watch/<id>"
yt-dlp "https://thumbs2.redgifs.com/<Name>.mp4"

5.5 Batch and Archive Mode

yt-dlp -a urls.txt --download-archive archive.txt
yt-dlp --no-overwrites --continue "URL"

5.6 Error Handling Patterns

  • Refresh token if API calls return 401
  • Use --add-header for Referer/Origin if 403 errors appear

6. FFmpeg Processing Techniques

FFmpeg is useful for validating MP4 outputs and remuxing any m4s segments referenced by playlists.

6.1 Inspect and Validate Streams

ffprobe -hide_banner -i "https://thumbs2.redgifs.com/<Name>.mp4"
ffmpeg -i "https://thumbs2.redgifs.com/<Name>.mp4" -c copy output.mp4

6.2 Common Remux and Repair Patterns

ffmpeg -i "playlist.m3u8" -c copy output.mp4
ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4
ffprobe -hide_banner -show_streams output.mp4

7. Alternative Tools and Backup Methods

7.1 Streamlink

streamlink "https://www.redgifs.com/watch/<id>" best -o output.mp4

7.2 aria2c

aria2c -o clip.mp4 "https://thumbs2.redgifs.com/<Name>.mp4"

7.3 gallery-dl

gallery-dl "https://www.redgifs.com/watch/<id>"

7.4 Browser DevTools

  • Look for api.redgifs.com/v2/gifs/ responses
  • Inspect JSON for mp4/gif URL fields
  • Capture direct MP4 request from thumbs2.redgifs.com

8. RedGifs API Integration

8.1 Known Endpoints

8.2 Example Requests

curl -X POST https://api.redgifs.com/v2/auth/temporary
curl -H 'Authorization: Bearer <token>' https://api.redgifs.com/v2/gifs/<id>

8.3 Token and Session Handling

  • Token responses include an access token and expiry
  • Use the token immediately; refresh on 401

9. Implementation Recommendations

9.1 Detection Hierarchy

  • Resolve watch/ifr URL to API metadata
  • Select highest quality MP4 from JSON response
  • Fallback to direct CDN URLs from network logs

9.2 Site-Specific Notes

  • Prefer MP4 URLs from the API response for stable downloads
  • Expose a download button for grid/feeds by reading data attributes

9.3 Storage and Naming Strategy

  • Use gif or mp4 extension based on selected asset
  • Include RedGifs ID in filenames for deduping

10. Troubleshooting and Edge Cases

  • API token expiration mid-download
  • Multiple encodes in response; choose best by resolution

11. Conclusion

RedGifs uses a tokenized API to expose direct MP4/GIF URLs on a CDN. Implementations should request temporary tokens, call the metadata endpoint, and select the best MP4 URL. yt-dlp can handle watch URLs directly, while ffmpeg and aria2c provide stable fallback downloads.

Tool Best Use Case Notes
yt-dlp Primary downloader for MP4/HLS Supports cookies, format selection, retries
ffmpeg Remuxing and validation Useful for HLS to MP4 conversion
streamlink Live/HLS fallback Streams to file or pipes into ffmpeg
aria2c Multi-connection HTTP/HLS downloads Good for large files and retries
gallery-dl Image-first or gallery-heavy sites Best for gallery or attachment extraction
