San Francisco, CA - Bay Area Video Coalition (BAVC) and the QCTools development team are announcing the release of version 1.0 of QCTools, an open-source application developed to help media archivists in assessing and analyzing the quality of their digitized video content. Version 1.0 is an important milestone in the development of QCTools. This version includes major updates that will enhance the user’s ability to analyze their digital video collections, as well as a newly developed Code of Conduct.

The two biggest updates to the application are the feature to save QCTools reports as MKV files, and the addition of the Barcharts view. The MKV report format is a huge step forward in improving collaborative workflows. An MKV report includes all of the signal graph data, as well as video thumbnails, allowing users to share and view reports without needing the original source file on-hand. The Barcharts feature displays boolean graphs based off the graphical data going above or below thresholds. The thresholds can be set by the user, exported, and shared with the preservation community.

Another highlight in this latest version of QCTools is the inclusion of a Code of Conduct. Maintaining a community that is free of harassment and discrimination is of the utmost importance in any collaborative project, especially those working within the open-source paradigm. The Code of Conduct is available on the project’s GitHub Page.

Here’s a quick rundown of version 1.0 updates and bug fixes:
