# Lightningbeam
|
|
|
|
A free and open-source 2D multimedia editor combining vector animation, audio production, and video editing in a single application.

## Current Features
|
|
|
|
**Vector Animation**
|
|
- Draw and animate vector shapes with keyframe-based timeline
|
|
- Non-destructive editing workflow
|
|
|
|
**Audio Production**
|
|
- Multi-track audio recording
|
|
- MIDI sequencing with synthesized and sampled instruments
|
|
- Integrated DAW functionality
|
|
|
|
**Video Editing**
|
|
- Basic video timeline and editing (early stage)
|
|
- FFmpeg-based video decoding
|
|
|
|
## Technical Stack
|
|
|
|
- **Frontend:** Vanilla JavaScript
|
|
- **Backend:** Rust (Tauri framework)
|
|
- **Audio:** cpal + dasp for audio processing
|
|
- **Video:** FFmpeg for encode/decode
|
|

|
## Project Status
|
|
|
|
Lightningbeam is under active development. Current focus is on core functionality and architecture. Full project export is not yet fully implemented.
|
|
|
|
### Known Architectural Challenge
|
|
|
|
The current Tauri implementation hits IPC bandwidth limitations when streaming decoded video frames from Rust to JavaScript. Tauri's IPC layer has significant serialization overhead (~few MB/s), which is insufficient for real-time high-resolution video rendering.
|
|
|
|
I'm currently exploring a full Rust rewrite using wgpu/egui to eliminate the IPC bottleneck and handle rendering entirely in native code.
|
|
|
|
## Project History
|
|
|
|
Lightningbeam evolved from earlier multimedia editing projects I've worked on since 2010, including the FreeJam DAW. The current JavaScript/Tauri iteration began in November 2023.

|
## Goals
|
|
|
|
Create a comprehensive FOSS alternative for 2D-focused multimedia work, integrating animation, audio, and video editing in a unified workflow. |
