How to create a video call filter in WhatsApp - in detail?
Creating a video call filter in WhatsApp involves several steps, from conceptualization to implementation. This process requires an understanding of both the technical aspects and user experience design principles. Below is a detailed guide on how to create a video call filter for WhatsApp:
- Conceptualization: Begin by defining the purpose and functionality of your filter. Determine what effect you want to achieve, such as beautifying the skin, adding fun animations, or applying colorful overlays. Understanding your target audience will help you tailor the filter to their preferences.
- Design: Use design tools like Adobe Photoshop or Illustrator to create the visual elements of your filter. Sketch out different versions and refine them based on feedback from colleagues or focus groups. Pay attention to details such as color schemes, transitions, and how the filter interacts with the user's face.
- Technical Setup: WhatsApp uses AR (Augmented Reality) technology for its filters. Familiarize yourself with the Spark AR Studio, which is a popular tool for creating AR effects. Download and install the software from Facebook’s developer website.

Creating the Effect in Spark AR Studio:
- Open Spark AR Studio and select "New Project."
- Choose a template that suits your filter idea. For example, if you want to create a face mask, select the "Face Mask" template.
- Use the Patch Editor to connect various nodes that define how your effect will behave. Nodes represent different aspects of the AR experience, such as textures, animations, and user interactions.
- Import your design elements into the project. Drag and drop them onto the Scene Panel to position them correctly on the face or in the environment.
- Testing: Use the preview function within Spark AR Studio to test your filter on different faces and in various lighting conditions. Adjust the nodes as necessary to ensure the effect works seamlessly across diverse situations.
- Optimization: WhatsApp filters need to be lightweight and efficient to run smoothly on users' devices. Optimize your effect by simplifying textures, reducing polygon count, and minimizing unnecessary computations.
- Exporting the Effect: Once you are satisfied with your filter, export it as a .effect file. This file contains all the necessary information for WhatsApp to recognize and apply your filter.
- Submission to WhatsApp: Follow WhatsApp's guidelines for submitting AR effects. This may involve creating a developer account and filling out submission forms. Be prepared to provide screenshots, videos, and descriptions of your filter.
- Review Process: Wait for WhatsApp’s review team to assess your filter. They will check for quality, functionality, and adherence to their guidelines. If approved, your filter will be available for users to enjoy during video calls on WhatsApp.
By following these steps meticulously, you can create a compelling video call filter that enhances the user experience on WhatsApp.
