QtWebMConverter is a simple, cross-platform, Qt-based frontend for ffmpeg aimed at making WebM videos.

Currently it supports VP8/VP9 and Vorbis/Opus in a WebM container. It only supports CRF encoding mode (because that's the one you want to use 9 out of 10 times anyway). More support (including other containers/codecs) might be added in the future.

The Windows version comes with a copy of ffmpeg included.

Download a release or clone the repository.

Extract the ZIP archive and run QtWebMConverter.exe. That's all.
