How to export your p5.js as a video

To export your p5.js sketch as a video requires an external library and some simple lines of code.

  1. Download the external library - it will be a zip file called "src" - Click this link to download the External Library Files

    P.S Before you start - turn off "auto-refresh" !!

  2. Go to your sketch - I am using a blank sketch to demonstrate - and click on the red triangle to open up the side bar menu.



  3. Click the drop down triangle - Create a folder called "src"


  4. Click the drop down triangle for the src folder - choose the upload file option


    upload all the extracted files from the Externals Library Files download.


  5. Click on the "index.html" file in the side bar - there will be some code inside - you need to add three lines for video exporting - refer to line 9, 10 and 11 in the image below


  1. Click on your sketch.js file in the side bar - add the capture device to your sketch - refer to line 1, 2 , 3 , 4 of the image below

  2. Go to your draw function - put this code at the beginning to start the capturing - refer to line 12, 13, 14 of the image below.

    8 - frameCount start - code.png

    This line of code is telling the sketch to start recording once the frameCount == 1.If you wanted to delay the recording by a certain amount of frames you can change this variable - calculating frames-per-second to time is given at the end of this tutorial.

  3. At the end of your code for draw add this last piece of code to finalise the recording process - refer to line 26, 27, 28, 29, 30, 31 of the image below. Please be aware of the "captureLength" variable which is defined on line 6

    9 - end code - variable - length calculator.png
