Internal Video Editor

Type: Unity Editor extension (Editor-only tool — produces video files; does not run at runtime or ship in a game build)

Platform: Windows 10 / 11, 64-bit Editor only. Requires a native x86_64 plugin built on Windows Media Foundation.

Unity versions: 2022.3 LTS or newer. Verified on Unity 2022.3, Unity 6000.0, and Unity 6000.3.

Render pipelines: Built-in, URP, and HDRP. All image processing runs through offscreen Graphics. Blit passes and never participates in scene rendering, so the tool is pipeline-independent.

Dependencies: None. No other Asset Store packages required, and no packages beyond Unity's built-in modules.

Package contents: 8 C# scripts (~22,400 lines, full source included), 2 blit shaders, 1 USS stylesheet, 9 editor icons, 1 native plugin (VideoEditorEncoder.dll, x86_64, Editor-only), user guide and license files. Download size: ~653 KB. All code is under the VideoEditor namespace.

Supported input

• Video: .mp4, .mov, .m4v, .mkv, .webm, .avi, .wmv (any format Windows Media Foundation can decode)
• Audio: .wav, .mp3, .m4a, .aac, .ogg, .flac, .wma, .aiff, .aif
• Images: any texture or sprite Unity can import (PNG, JPG, TGA, PSD, EXR, TIFF, BMP)
• Media can be imported into the project or linked by file path without importing

Export

• MP4 / H.264 via Media Foundation — works out of the box, no downloads
• MOV container, H.265, and exact target bitrate via optional FFmpeg (free, LGPL, downloaded on first use, not bundled)
• Output resolution 16–8192 px per axis (even dimensions); batch Render Queue with per-job timeline snapshots

Third-party software

• FFmpeg — optional, not bundled, LGPL v2.1+ (FFMPEG_NOTICE.txt)
• Signalsmith Stretch / Linear — bundled, MIT, used for audio pitch and time-stretch (THIRD-PARTY-LICENSES.txt)

Documentation: USER_GUIDE.md included; credits and links also under Settings ▸ About / Credits in the editor window.

Internal Video Editor is a complete non-linear video editor that runs inside the Unity Editor. Cut, grade, and export your footage without going to an external app.

Built for developers who record gameplay — dev logs, clips for socials, trailers, and store marketing. Drop your recordings onto a multi-track timeline, trim and arrange, grade the color, key out a green screen, animate with keyframes, mix and EQ the audio, then export an MP4. All in one window, without leaving your project.
