LosslessCut's technical principles
- FFmpeg library: LosslessCut is developed based on the FFmpeg library. FFmpeg is an open-source multimedia framework
- Direct stream editing: LosslessCut achieves lossless cutting by directly manipulating the data streams of video files, avoiding the re-encoding process in traditional editing software.
- Index modification: When cutting video, LosslessCut only modifies the file's index information and does not need to re-encode the entire video, enabling fast processing.
- Multi-track processing: Based on FFmpeg's multi-track processing capabilities, users can freely combine and edit multiple video and audio tracks.
- Smart cut: Integrates machine learning algorithms to recognize content in videos and enable automated editing decisions.
- Command line and API: LosslessCut provides a command-line interface and HTTP API, integrates into automated workflows, and can be operated programmatically.
