Pure Go Engine

Zero-dependency core compiler that turns declarative timeline trees into optimized FFmpeg filtergraphs in sub-millisecond speeds.

📐

Graph Optimization & IR

Auto-split stream isolation, dead-code elimination, and format normalization prevent FFmpeg runtime pad collisions.

🎬

Native Desktop Workstation

Full-fledged non-linear editing studio engineered with Wails v2, Vue 3, and Nuxt UI. Zero Electron bloat.

🎛️

Studio Effects Built-in

Sidechain audio ducking, reactive podcast waveforms, green screen despill, styled SRT burn-in, and keyframe motion.

⏱️

Zero-Drift Math

Exact fractional rational timing prevents cumulative millisecond drift across thousands of frames.

🚀

Hardware Acceleration

Native one-flag auto-detection for NVIDIA NVENC, Apple VideoToolbox, Intel QSV, and VAAPI.

🚀 Quick Example

Compose and render a multi-layered video with picture-in-picture in pure Go:

package main

import (
	"context"
	"time"

	"github.com/farshidrezaei/vidonex/composer"
	"github.com/farshidrezaei/vidonex/timeline"
	"github.com/farshidrezaei/vidonex/types"
)

func main() {
	tl := timeline.New(
		timeline.WithCanvas(types.Res1080p),
		timeline.WithFPS(types.FPS60),
	)

	// Layer 0: Background Video
	baseTrack := timeline.NewTrack("video", timeline.TrackKindVideo)
	baseTrack.AddClip(timeline.NewClip("intro", "gameplay.mp4", 0, 10*time.Second))

	// Layer 1: Facecam PiP Overlay
	pipTrack := timeline.NewTrack("pip", timeline.TrackKindOverlay).SetZIndex(1)
	pipTrack.AddClip(
		timeline.NewClip("webcam", "facecam.mp4", 0, 10*time.Second).
			WithScale(0.3).
			WithPosition(types.Point{X: 1300, Y: 40}),
	)

	tl.AddTrack(baseTrack, pipTrack)

	// Compile & Render via OS FFmpeg
	c := composer.New()
	_, _ = c.Render(context.Background(), tl, "output.mp4", nil)
}
