Ffmpeg Render Pro tools (7)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • color_grade

    Apply a color grade to a video file and write the result to a new file. Provide either a built-in preset (…) or a custom ffmpeg -vf filter string (filter overrides preset). Re-encodes the video stream with the chosen codec; audio is stripped unless keep_audio is true. Prerequisite: ffmpeg installed. Side effect: overwrites output_path if it already exists.

  • concat_videos

    Join multiple video files into one with stream copy: no re-encoding, completes in seconds regardless of file size. All inputs must share the same codec, resolution, framerate, and pixel format. By default each input is probed with ffprobe and mismatches are rejected before ffmpeg runs, because ffmpeg itself accepts mismatched inputs and writes a silently corrupt file; set validate false to skip th

  • detect_gpu

    Detect the best available hardware video encoder on this machine. Probes NVENC, VideoToolbox, AMF, VA-API, and QSV with a 1-frame validation encode and falls back to CPU (libx264) when no GPU encoder works. Use before rendering or grading to confirm hardware acceleration. Results are cached for 7 days in ~/.ffmpeg-render-pro/gpu-cache.json. Requires ffmpeg on PATH or FFMPEG_RENDER_PRO_FFMPEG.

  • get_worker_template

    Get the worker script contract required by render_video, plus the full source of the bundled starter worker (a small file where only renderFrame() needs editing) and the path of the larger reference worker. Use this before authoring a custom worker: copy starterSource to a new file, replace renderFrame(), and pass that file as worker_script. Either templatePath (test scene) or starterPath (gradien

  • merge_audio

    Combine a video file and an audio file into one output file. The video stream is copied without re-encoding; audio is encoded to AAC at the given bitrate. Loops audio shorter than the video when loop is true, and can apply loudness normalization (ffmpeg loudnorm) for YouTube-style targets. Prerequisite: ffmpeg installed. Side effect: overwrites output_path if it already exists.

  • render_video
  • system_info

    Get render system capabilities: CPU cores, total and free RAM, the recommended parallel worker count for a target resolution, detected GPU encoder, segment and final codecs, and ffmpeg version. Use before render_video to choose a worker count or check whether this machine can handle a resolution. Requires ffmpeg on PATH or FFMPEG_RENDER_PRO_FFMPEG.

What the publisher says

From the Ffmpeg Render Pro repository's README, as published. We do not edit it. Read it on GitHub

ffmpeg-render-pro

Render video from code, in parallel. You write one function that paints a frame; ffmpeg-render-pro splits the frame range across worker threads, encodes one MP4 segment per worker, joins the segments with stream copy (no re-encode), and shows a live dashboard in your browser while it runs. It also detects GPU encoders, grades color, merges audio, and ships as a CLI, a Node library, an MCP server for AI agents, and a Claude Code skill.

Built by Beeswax Pat. Free and open source.

Start here

Three commands. You need Node.js 18 or newer and ffmpeg on your PATH.

# 1. Prove the setup works: a 5 second test render. The dashboard opens in your browser.
npx ffmpeg-render-pro benchmark

# 2. Write a starter worker script into the current folder.
npx ffmpeg-render-pro init my-worker.js

# 3. Render it. Output lands in output.mp4.
npx ffmpeg-render-pro render my-worker.js --duration=5

Open my-worker.js. The only function you need to change is renderFrame(frameNum, buffer): fill the buffer with your pixels (B, G, R, A, one row after another) and everything else is already done. Derive any randomness from the seed it receives and parallel output stays identical to a sequential render.

Install it globally if you would rather not type npx:

npm install -g ffmpeg-render-pro

Using an ffmpeg that is not on PATH

FFMPEG_RENDER_PRO_FFMPEG=/opt/ffmpeg/bin/ffmpeg     # ffmpeg binary
FFMPEG_RENDER_PRO_FFPROBE=/opt/ffmpeg/bin/ffprobe   # optional; the sibling ffprobe is found automatically
FFMPEG_RENDER_PRO_CACHE_DIR=~/.ffmpeg-render-pro    # optional; where GPU probe results are cached

The variables are read at call time, so a long-running process such as the MCP server picks up changes without a restart.

CLI

ffmpeg-render-pro init [my-worker.js]   # write the starter worker (--force overwrites)
ffmpeg-render-pro benchmark             # 5 second test render with the bundled worker
ffmpeg-render-pro render <worker.js>    # render with your worker
ffmpeg-render-pro info                  # cores, RAM, recommended workers, ffmpeg version, GPU
ffmpeg-render-pro detect-gpu            # probe hardware encoders (--cpu / --gpu force a mode)
ffmpeg-render-pro version

Render and benchmark flags: --width=1920 --height=1080 (must be even), --fps=60, --duration=60 (fractions allowed), --output=out.mp4, --workers=N, --max-workers=8, --seed=42, --title="...", --crf=20 (0-51, lower is higher quality), --encoder-preset=fast (any x264 preset). Dashboard flags: --no-dashboard, --no-open, --port=8080, --linger-ms=30000 (0 exits as soon as the render finishes). Run ffmpeg-render-pro with no arguments for the full list.

An unknown flag warns and continues. A value that does not parse, such as --fps=abc, exits 1 instead of rendering at the default.

Installed binaries: ffmpeg-render-pro (this CLI) and ffmpeg-render-pro-mcp (the MCP server). The older ffmpeg-render-mcp name still works so existing MCP configs never break.
