Olive
Olive is an open-source non-linear video editor and multi-track compositor designed for digital video production. It provides a desktop application for arranging, cutting, and trimming video and audio clips on a timeline to create high-resolution cinematic content.
The software employs a proxy-based editing workflow, substituting high-resolution assets with low-bitrate temporary files to maintain fluid playback and scrubbing performance. This is supported by a non-destructive timeline engine that maps media clips using metadata pointers rather than modifying original source files.
The system manages visual and auditory elements through multi-track composition using a z-order layer hierarchy. It utilizes a deferred rendering pipeline and a plugin-based effect system to process filters and transitions during the final export phase. Real-time navigation is facilitated by a preview buffer that caches decoded frames in memory.
Features
