Transform Studio Implementation Plan

Overview

Transform Studio allows users to convert videos between formats, change aspect ratios, adjust speed, compress, and apply style transfers to videos.

Features Breakdown

✅ No AI Documentation Needed (FFmpeg/MoviePy-based)

These features can be implemented immediately using existing video processing libraries:

Format Conversion (MP4, MOV, WebM, GIF)
- Tool: FFmpeg/MoviePy
- No AI models needed
- Can implement immediately
Aspect Ratio Conversion (16:9 ↔ 9:16 ↔ 1:1)
- Tool: FFmpeg/MoviePy
- No AI models needed
- Can implement immediately
Speed Adjustment (Slow motion, fast forward)
- Tool: FFmpeg/MoviePy
- No AI models needed
- Can implement immediately
Resolution Scaling (Scale up or down)
- Tool: FFmpeg/MoviePy
- Note: We already have FlashVSR for AI upscaling (in Enhance Studio)
- For downscaling/simple scaling, FFmpeg is sufficient
- Can implement immediately
Compression (Optimize file size)
- Tool: FFmpeg/MoviePy
- No AI models needed
- Can implement immediately

⚠️ AI Documentation Needed (Style Transfer)

For video-to-video style transfer, we need WaveSpeed AI model documentation:

Required Models:

WAN 2.1 Ditto - Video-to-Video Restyle
- Model: wavespeed-ai/wan-2.1/ditto
- Purpose: Apply artistic styles to videos
- Documentation needed:
  - API endpoint
  - Input parameters (video, style prompt/reference)
  - Output format
  - Pricing
  - Supported resolutions/durations
  - Use cases and best practices
- WaveSpeed Link: Need to find/verify
WAN 2.1 Synthetic-to-Real Ditto
- Model: wavespeed-ai/wan-2.1/synthetic-to-real-ditto
- Purpose: Convert synthetic/AI-generated videos to realistic style
- Documentation needed:
  - API endpoint
  - Input parameters
  - Output format
  - Pricing
  - Use cases
- WaveSpeed Link: Need to find/verify

Optional Models (Future):

SFX V1.5 Video-to-Video
- Model: mirelo-ai/sfx-v1.5/video-to-video
- Purpose: Video style transfer
- Documentation: Can be added later
Lucy Edit Pro
- Model: decart/lucy-edit-pro
- Purpose: Advanced video editing and style transfer
- Documentation: Can be added later

Implementation Strategy

Phase 1: Immediate Implementation (No Docs Needed)

Start with FFmpeg-based features:

Format Conversion
- MP4, MOV, WebM, GIF
- Codec selection (H.264, VP9, etc.)
- Quality presets
Aspect Ratio Conversion
- 16:9, 9:16, 1:1, 4:5, 21:9
- Smart cropping (center, face detection, etc.)
- Letterboxing/pillarboxing options
Speed Adjustment
- 0.25x, 0.5x, 1.5x, 2x, 4x
- Smooth frame interpolation
Resolution Scaling
- Scale to target resolution
- Maintain aspect ratio
- Quality presets
Compression
- Target file size
- Quality-based compression
- Bitrate control

Phase 2: Style Transfer (After Documentation)

Once we have model documentation:

Add Style Transfer Tab
Implement WAN 2.1 Ditto integration
Implement Synthetic-to-Real Ditto
Add style presets (Cinematic, Vintage, Artistic, etc.)

POST /api/video-studio/transform

Request Parameters:

Summary

Can Start Immediately ✅

Format Conversion
Aspect Ratio Conversion
Speed Adjustment
Resolution Scaling
Compression

Tools: FFmpeg/MoviePy (already available in codebase via MoviePy)

Need Documentation First ⚠️

Style Transfer - Need WaveSpeed AI model docs for:
1. wavespeed-ai/wan-2.1/ditto
2. wavespeed-ai/wan-2.1/synthetic-to-real-ditto

Recommendation

Start Phase 1 (FFmpeg features) - Can implement immediately
Request documentation for style transfer models
Implement Phase 2 (Style transfer) once docs are available

This allows us to deliver 80% of Transform Studio functionality immediately while waiting for AI model documentation.
