OpenMontage is an open-source video production system you drive through an AI coding assistant. You describe the video in plain language and the agent handles research, scripting, asset generation, editing, and final composition with Remotion, showing per-asset cost and approval gates along the way.

FFmpeg bundles a set of libraries and command-line tools, hosted at FFmpeg/FFmpeg on GitHub, built for working with audio, video, subtitles, and the metadata attached to them. The project centers on libavcodec, libavformat, libavutil, libavfilter, libavdevice, libswresample, and libswscale, plus three CLI tools: ffmpeg for conversion and streaming, ffplay for playback, and ffprobe for inspecting files. Its README frames licensing as split, primarily LGPL with select optional pieces under GPL, and routes contributions through the ffmpeg-devel mailing list instead of GitHub pull requests.
