4DAnyone is an open-source generative AI pipeline from ant-research that converts a casual monocular video of one person into synchronized videos from multiple virtual camera views for downstream 3D or 4D Gaussian-splatting reconstruction. It supports configurable camera layouts, including full 360-degree or frontal-arc coverage, multiple pitch layers, adjustable yaw ranges, and flexible view counts. The repository provides inference scripts, automatically downloadable models and examples, motion-recovery outputs, camera metadata, skeleton videos, and generated target-view videos. Input footage should be at least 720p, preferably 1080p, use a 9:16 portrait aspect ratio, contain a single person in a full-body or upper-body shot, include at least 121 frames, and have only mild camera motion.

JoyAI-Video-Edit is an open-source, instruction-guided system for editing live camera streams or uploaded videos as frames arrive. It processes frames causally without waiting for the complete video, requiring a predefined sequence length, or revisiting future frames, and supports subject and local edits, background replacement, style and motion changes, and reference-guided editing. Its autoregressive diffusion architecture combines an MLLM-based condition encoder, a causal video VAE, and a 16-billion-parameter multimodal diffusion transformer. The deployment uses aligned autoregressive distribution-matching distillation, long-horizon optimization, bounded KV-state inference, and deployment-oriented scheduling to reduce train–inference mismatch and temporal drift during streaming generation. The repository reports 30 FPS end-to-end throughput at 720 × 1248 in its deployment benchmark. The repository provides deployment code and model checkpoints, a local server with a browser interface, and instructions for CUDA-based inference. It is licensed under Apache 2.0.

video-use is an open-source video-editing tool for coding agents such as Claude Code, Codex, Hermes, and Openclaw. It takes raw footage in a folder and produces an edited MP4, with support for removing filler words and dead space, applying FFmpeg color-grading chains, adding short audio fades at cuts, burning customizable subtitles, and generating animation overlays through HyperFrames, Remotion, Manim, or PIL. Its pipeline transcribes each source with ElevenLabs Scribe, packing word-level timestamps, speaker diarization, and audio events into a Markdown view. The agent reasons over that transcript and requests filmstrip, waveform, and word-label composites from timeline_view only at decision points, rather than processing every video frame as visual context. It then creates an edit decision list, renders the result, evaluates the rendered video at every cut boundary for visual jumps, audio pops, and subtitle problems, and can revise and re-render up to three times. The tool uses an approval-oriented workflow in which the agent inventories sources, proposes an editing strategy, waits for confirmation, executes the edit, evaluates it, and persists session memory in project.md. It requires FFmpeg and an ElevenLabs API key; yt-dlp is optional for downloading online sources. Outputs are placed in an edit directory next to the source footage.

FFmpeg is a collection of libraries and command-line tools for processing multimedia content, including audio, video, subtitles, and related metadata. Its libraries provide codec implementations, streaming and container-format handling, filtering through directed graphs, device access, audio mixing and resampling, and image scaling and color conversion. The toolset includes ffmpeg for manipulating, converting, and streaming media, ffplay for playback, and ffprobe for inspecting media content. The codebase is mainly licensed under the LGPL, with optional components under the GPL. The repository is an official mirror of the FFmpeg project's Git repository; the project directs contributors to submit patches through its mailing list rather than GitHub pull requests.

Shrimply is a free, open-source video editor for creating videos from start to finish. Its main application is written in Rust with a GTK 4 and libadwaita interface; rendering uses Skia, wgpu, Slang, and CUDA, while FFmpeg and PipeWire handle media and a Python component provides the compute server. The project is pre-alpha software and warns of undocumented footguns, performance regressions, irreversible project-file breakage, crashes, resource leaks, and security limitations. It is licensed under GNU GPL version 3 or later, although some features depend on separately licensed NVIDIA components and model weights.
