It is OK, if you don’t know what is VLMC because it hasn’t been released yet. VLMC (VideoLAN Movie Creator) is a free video editing software, offering features to realize semi-professional quality movies, but with the aim to stay simple and user-friendly.
VLMC is being developed with the support of the VideoLAN organization (the house of the famous VLC Media Player). The pre-release version will be available soon.
It took me a while to install vlmc from the source code and I can say it is not so easy. However, vlmc is currently under heavy developing and doesn’t offer advanced tools for video editing.
After playing with vlmc, I feel that it is simple, use-friendly, and stable (believe it or not ). Although, vlmc is under an early developing stage, It offers basic tools like resizing, trimming, render and history.
