    Assuming you would like to record p5.js animations super easily, this package is the right choice for you.

    Why p5.capture?

    🎩 Stable recording

    Recording p5.js animations with screen recording tools can cause jerky recordings. Complex animations can slow down the framerate and make recording unstable. p5.capture hooks into the p5.js draw function and records the rendered frame, so it works like magic.

    ✨ Keep your sketch clean

    Adding recording functionality to a sketch can be very tedious. p5.capture provides a minimal GUI and is designed to add recording functionality without adding any code to your sketch. Let's focus on your creative coding. Of course, you can also use the API to integrate it into your code.

    🀹 Any format β€’ One API

    Tired of having to use different libraries for different formats? p5.capture supports many export formats including WebM, GIF, MP4, PNG, JPG, and WebP. There is sure to be something you want.

    Getting started


    Insert a link to the p5.capture after p5.js in your html file:

    <script src="https://cdn.jsdelivr.net/npm/p5@1.4.1/lib/p5.min.js"></script>
    <!-- insert after p5.js -->
    <script src="https://cdn.jsdelivr.net/npm/p5.capture@1.2.0/dist/p5.capture.umd.min.js"></script>

    You can find all versions in the jsDelivr.


    Basically, the GUI provided by p5.capture starts and stops recording.


    That's all πŸŽ‰

    Export formats

    Supported formats include:

    • WebM (default): export WebM video using webm-writer-js
    • GIF: export animated GIF using gif.js
    • MP4: export MP4 video using h264-mp4-encoder
    • PNG: export PNG images in a ZIP file
    • JPG: export JPG images in a ZIP file
    • WebP: export WebP images in a ZIP file


    The P5Capture class can be used to programmatically control recording.

    Static methods


    Returns a P5Capture instance.
    Used to access the P5Capture instance automatically created when p5.capture is initialized.


    Change default options. These options affect both GUI and API recording.
    Must be used before p5.js initialization.

      format: "gif",
      framerate: 10,
      quality: 0.5,
      width: 320,
    function setup() {
      // do something...

    Instance methods


    Start recording with the specified options.
    options can be omitted.


    Stop recording and start encoding.
    Download files after encoding is complete.

    Instance properties

    state (Read only)

    Returns the current recording state ("idle", "capturing", or "encoding").


    The following example shows how to record the first 100 frames and create a GIF video:

    function draw() {
      if (frameCount === 1) {
        const capture = P5Capture.getInstance();
          format: "gif",
          duration: 100,
      // do something...

    The following example shows how to add an event handler that starts and stops recording with a keystroke:

    function keyPressed() {
      if (key === "c") {
        const capture = P5Capture.getInstance();
        if (capture.state === "idle") {
        } else {


    Name Default Description
    format "webm" export format. "webm", "gif", "mp4", "png", "jpg", and "webp"
    framerate 30 recording framerate
    bitrate 5000 recording bitrate in kbps (only available for MP4)
    quality see Quality option recording quality from 0 (worst) to 1 (best). (only available for WebM/GIF/JPG/WebP)
    width canvas width output image width
    height canvas height output image height
    duration null maximum recording duration in number of frames
    autoSaveDuration null automatically downloads every n frames. convenient for long captures (only available for PNG/JPG/WebP)
    verbose false dumps info on the console
    disableUi false (only P5Capture.setDefaultOptions()) hides the UI
    disableScaling false (only P5Capture.setDefaultOptions()) disables pixel scaling for high pixel density displays
