The main project I worked on is a user interface for the Ken-Burns effect in Pitivi.
Link to the task: https://phabricator.freedesktop.org/T7340
The code for this feature is divided in 9 commits, which are the top commits of this branch: https://github.com/stefanzzz22/pitivi/commits/wip/phab/T7340-Ken-Burns
