Speaker
Description
This talk will provide an update on the latest developments in GStreamer Editing Services (GES), with a special focus on the newly stabilized linear time remapping feature. Time remapping enables powerful video effects like slow motion, fast forward, and reverse playback by manipulating the relationship between input and output timestamps. We'll explore how this feature has been implemented at the GStreamer and NLE level. The presentation will cover the core GStreamer elements involved, the challenges we faced, and how these capabilities are exposed through GES for video editing applications. We'll also discuss the roadmap ahead, including exploring future work on dynamic speed changes during playback (smoothly transitioning from normal to slow motion while playing) and other improvements to the GES stack.
