Video Editing & Compositing SDK for .NET
Build professional video editing and post-production applications with VisioForge SDKs. Video joining, multi-layer compositing with chroma key, GPU-accelerated effects, LUT color grading, audio track replacement — all from C# and .NET.
Video Editing Development Challenges
Multi-Source Compositing
Combining cameras, screen captures, video files, and images into a single output with precise positioning, z-ordering, and alpha blending requires a robust mixer architecture.
GPU-Accelerated Effects
Applying real-time video effects like blur, color grading, and custom shaders without dropping frames demands GPU pipeline integration with OpenGL/Direct3D.
Format & Codec Diversity
Joining and rendering videos across MP4, WebM, AVI, MKV formats with different codecs, resolutions, and frame rates into a unified output.
Audio Track Management
Replacing, mixing, or removing audio tracks from video files while maintaining A/V sync and supporting multiple audio formats (MP3, AAC, WAV).
How VisioForge SDKs Solve These Challenges
VisioForge provides both high-level VideoEditCoreX for common editing workflows and low-level Media Blocks SDK for custom compositing pipelines. Mix multiple sources in real-time, apply GPU shaders, and render to any output format.
- VideoMixerBlock composites multiple sources with positioning, z-order, and alpha blending
- Chroma key (green screen) compositing with configurable sensitivity and noise levels
- GPU-accelerated effects via OpenGL shader blocks (blur, color correction, custom GLSL)
- LUT color grading with .cube file support for cinematic looks
- VideoEditCoreX joins video/audio/image files with format conversion
- Audio replacement and mixing without re-encoding video tracks
Key Video Editing Features
Video Compositing & Mixing
Combine cameras, files, screens, and images with per-source positioning, z-ordering, alpha blending, and fade in/out transitions.
Chroma Key (Green Screen)
Real-time chroma key compositing with configurable color selection, sensitivity, and noise level. Supports green, blue, and custom key colors.
GPU Shader Effects
Apply Gaussian blur, custom GLSL shaders, and real-time video effects using OpenGL pipeline with configurable parameters.
LUT Color Grading
Apply .cube LUT files for cinematic color grading. Preview original and graded video side-by-side using tee blocks.
Video Joining & Conversion
Join multiple video, audio, and image files into a single output. Supports MP4, WebM, AVI, MKV, WMV, and more formats.

C#Pipeline Architecture
VisioForge Media Blocks SDK uses a modular pipeline architecture. Each block handles one task — source, mix, effect, encode, render — and blocks connect together to form complete editing workflows.
