Discord Video Compressor

Русская версия

Windows desktop application that compresses videos to a selected file-size limit using FFmpeg.

Features

• MP4/H.264 and WebM/VP9 output.
• Preset 9 MB target and custom size limits.
• Drag and drop and Explorer context-menu conversion.
• Videos with or without an audio stream.
• Resolution, frame-rate, sample-rate and sample-format controls.
• Optional speed, glitch and datamosh effects.
• Progress stages, encoding speed, ETA and cancellation.
• English and Russian UI, system dark-mode integration.
• Signed automatic updates through NetSparkle.

Requirements

• Windows 10 version 1809 or newer, x64.
• Visual Studio 2022 or .NET 8 SDK for source builds.
• Git LFS when cloning the repository because ffmpeg.exe is an LFS object.

The release installer is self-contained. End users do not need to install .NET or FFmpeg separately.

Build

git lfs install
git clone https://github.com/KickerMix/DiscordVideoCompressor.git
cd DiscordVideoCompressor
dotnet build DiscordVideoCompressor.sln -c Release
dotnet test DiscordVideoCompressor.sln -c Release

Build the Windows installer with:

.\installer\Build-Installer.ps1

Inno Setup 6 must be installed for the installer step.

Usage

1. Select or drop an .mp4, .avi, .mkv or .webm file.
2. Choose MP4 or WebM and the target size.
3. Adjust optional encoding/effect settings.
4. Start conversion. Output is written beside the source file using a _cnvrtd suffix; an index is added instead of overwriting an existing file.

The installer can add an Explorer context-menu command. Context-menu conversion uses the 9 MB MP4 preset and places the output file on the clipboard when done.

FFmpeg Runtime

FFmpeg 8.1 is embedded in the application. At runtime it is extracted once to a content-hashed cache file under %TEMP%\DiscordVideoCompressor. Obsolete cache copies are removed automatically.
