# 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:
|
|
|
|
1. **Format Conversion** (MP4, MOV, WebM, GIF)
|
|
- Tool: FFmpeg/MoviePy
|
|
- No AI models needed
|
|
- Can implement immediately
|
|
|
|
2. **Aspect Ratio Conversion** (16:9 ↔ 9:16 ↔ 1:1)
|
|
- Tool: FFmpeg/MoviePy
|
|
- No AI models needed
|
|
- Can implement immediately
|
|
|
|
3. **Speed Adjustment** (Slow motion, fast forward)
|
|
- Tool: FFmpeg/MoviePy
|
|
- No AI models needed
|
|
- Can implement immediately
|
|
|
|
4. **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
|
|
|
|
5. **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:
|
|
|
|
1. **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
|
|
|
|
2. **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):
|
|
|
|
3. **SFX V1.5 Video-to-Video**
|
|
- Model: `mirelo-ai/sfx-v1.5/video-to-video`
|
|
- Purpose: Video style transfer
|
|
- Documentation: Can be added later
|
|
|
|
4. **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:
|
|
|
|
1. **Format Conversion**
|
|
- MP4, MOV, WebM, GIF
|
|
- Codec selection (H.264, VP9, etc.)
|
|
- Quality presets
|
|
|
|
2. **Aspect Ratio Conversion**
|
|
- 16:9, 9:16, 1:1, 4:5, 21:9
|
|
- Smart cropping (center, face detection, etc.)
|
|
- Letterboxing/pillarboxing options
|
|
|
|
3. **Speed Adjustment**
|
|
- 0.25x, 0.5x, 1.5x, 2x, 4x
|
|
- Smooth frame interpolation
|
|
|
|
4. **Resolution Scaling**
|
|
- Scale to target resolution
|
|
- Maintain aspect ratio
|
|
- Quality presets
|
|
|
|
5. **Compression**
|
|
- Target file size
|
|
- Quality-based compression
|
|
- Bitrate control
|
|
|
|
### Phase 2: Style Transfer (After Documentation)
|
|
|
|
Once we have model documentation:
|
|
|
|
1. **Add Style Transfer Tab**
|
|
2. **Implement WAN 2.1 Ditto integration**
|
|
3. **Implement Synthetic-to-Real Ditto**
|
|
4. **Add style presets (Cinematic, Vintage, Artistic, etc.)**
|
|
|
|

|
## 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
|
|
|
|
1. **Start Phase 1** (FFmpeg features) - Can implement immediately
|
|
2. **Request documentation** for style transfer models
|
|
3. **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.
