Recording WhatsApp video calls on Android and iOS can be a useful feature for various purposes, such as keeping a record of important conversations or sharing moments with friends and family. However, it's essential to respect privacy and legal considerations when recording video calls, and you should always obtain the consent of the other party before recording. The following instructions elucidate the process of recording WhatsApp video calls on both Android and iOS platforms:

On Android:

Use Built-in Screen Recorder (Android 11 and later):

Android 11 and later versions have a built-in screen recording feature. To use it:
To access the notification shade, kindly swipe downwards from the top of your screen.
Look for the "Screen Recording" toggle and tap on it to start recording.

You can start your WhatsApp video call, and the screen recorder will capture both the audio and video of the call.

Use Third-Party Screen Recording Apps (Android 10 and earlier):

If you're using an Android version earlier than Android 11, you can use third-party screen recording apps. Some popular options include AZ Screen Recorder and DU Recorder.

Proceed to download and install a screen recording application from the Google Play Store.

Open the app and configure its settings.

Start your WhatsApp video call, and use the screen recording app to capture the call.
Record with WhatsApp's Built-in Feature (participating in WhatsApp beta program):

WhatsApp was reportedly testing a built-in call recording feature in its beta program. If you're part of the WhatsApp beta program, you can check if this feature is available for you.

On iOS:

Use the Built-in Screen Recording Feature:

iOS has a built-in screen recording feature that works for all apps, including WhatsApp. To use it:

Swipe down from the upper-right corner (or swipe up from the bottom if you have an older iPhone) to open the Control Center.

Tap the Screen Recording icon (a circle with a dot inside) to start recording.

You can then start your WhatsApp video call, and it will be recorded.

Use a Mac Computer (with macOS Catalina or later):

If you have a Mac running macOS Catalina or later, you can use the QuickTime Player to record WhatsApp video calls from your iPhone.

Please connect your iPhone to your Mac computer by utilizing a USB cable.

Open QuickTime Player on your Mac.

Go to "File" > "New Movie Recording."

Click the arrow next to the record button and select your iPhone as the camera source.

Start your WhatsApp video call on your iPhone, and QuickTime will record it on your Mac.
