Keyframe Lossless Video Cutter

Keyframe Lossless Video Cutter is a desktop timeline video trimmer, multi-segment
joiner, keyframe inspector, and video filter re-encoder for Linux.
A lightweight Linux alternative to VirtualDub2 for instant lossless stream cutting
along I-frame boundaries alongside filtered H.264 and VP9 video processing.

Key Features:
- Stream Probe, Keyframe Map & Thumbnail Filmstrip: Inspects container and track
metadata, extracts exact I-frame keyframe timestamps (PTS), and renders a visual
thumbnail filmstrip above an interactive multi-segment timeline.
- Multi-Segment Cut & Lossless Joiner: Marks multiple In and Out cut ranges with
one-click keyframe jump navigation and exports single or concatenated segments via
instant lossless stream copy (-c copy) with zero generation quality loss.
- Video Filter Pipeline & H.264/VP9 Re-Encoding: Applies configurable crop, resolution
scale, yadif deinterlacing, hqdn3d 3D denoising, and eq brightness/contrast/gamma/
saturation color grading with live frame preview before H.264 or VP9 encoding.
- Full-Resolution Frame Snapshot & Reports: Captures exact timeline video frames to
PNG images and exports complete keyframe PTS maps to JSON and CSV files.
