Compatibility
Operating System
Section titled “Operating System”| Platform | Supported |
|---|---|
| macOS 12 (Monterey) or later | Yes |
| Windows | No |
| Linux | No |
modelBridge is macOS only. The backend server uses macOS-specific tools (lsof for port detection, Homebrew node paths) that do not have Windows equivalents in the current version.
Adobe Premiere Pro
Section titled “Adobe Premiere Pro”| Version | CEP Version | Supported |
|---|---|---|
| Premiere Pro 2023 (23.x) | CEP 11 | Yes |
| Premiere Pro 2024 (24.x) | CEP 11 | Yes |
| Premiere Pro 2025 (25.x) | CEP 11 | Yes |
| Premiere Pro 2022 and earlier | CEP 9/10 | No |
The extension is built to be compatible with all current and foreseeable Premiere Pro releases.
Node.js
Section titled “Node.js”| Requirement | Detail |
|---|---|
| Minimum version | Node.js 18 |
| Recommended | Node.js 20 LTS or later |
| Installation | Via nodejs.org or Homebrew (brew install node) |
The local backend server requires Node.js to run. If Node.js is installed via Homebrew or the standard installer, modelBridge finds it automatically.
Network
Section titled “Network”| Port | Purpose |
|---|---|
| 3000 | Local backend server |
Port 3000 must be available on localhost. If another application is using it, the server manager will detect the conflict and report an error. No external ports need to be opened — all API communication goes outbound to fal.ai over HTTPS.
An active internet connection is required for:
- fal.ai API communication (generation, polling, schema fetching)
- Pricing data updates
- License validation
Supported Media Formats
Section titled “Supported Media Formats”Input (source clips)
Section titled “Input (source clips)”modelBridge works with any media format that Premiere Pro can import and play, including:
- Video: H.264, H.265/HEVC, ProRes, DNxHD/DNxHR, AVI, MOV, MP4
- Image: JPEG, PNG, TIFF, BMP, PSD, WebP
- Audio: WAV, MP3, AAC, AIFF
The actual media is extracted from the timeline at generation time and uploaded to fal.ai as a temporary file.
Output (generated content)
Section titled “Output (generated content)”Generated content is returned by fal.ai and imported into Premiere Pro automatically. Output formats depend on the model:
- Video models typically return MP4 (H.264)
- Image models typically return PNG or JPEG
- Audio models typically return WAV or MP3
Panel Dimensions
Section titled “Panel Dimensions”The modelBridge panel operates within Premiere Pro’s panel framework. The minimum panel width is approximately 280px. The UI is optimized for this narrow panel layout, with responsive elements that adapt to available space.
