WhatsApp just updated its beta version and now supports up to 8 participants in video calls, so that limit is officially extended, although we are waiting for it to reach all users through the stable version of the application.
We already spoke at the time that WhatsApp had the intention of expanding the limit of people who can be in a video call, the information that we needed to know the exact number that would be allowed and now we know it, it which means that will be twice as much as before
So far 4 people can participate including the caller or yourself if you are the one who initiates the video call. That's a low number of participants when compared to other apps like Zoom, Skype, and other similar apps for video calls.
You should know a very important detail according to WABetaInfo, users who are going to participate in the video call to 8 must all have the same version of WhatsApp, or failing that, one that already has support for the 8 participants in video calls.

That is, if the stable update arrives and you update, you will have the limit of 8 participants, but if the friend or relative with the that you are going to make the video call has not updated WhatsApp, it will not have support for this functionality, so you will not be able to participate in the video call.
The new limit is only available in the beta of WhatsApp for iOS and Android, so the only way to have it is to update the application, something that most users cannot do because it is not within the beta program of the app.
With this in mind, the ability to make video calls with up to 8 people shouldn't be long in coming to the stable version of WhatsApp It's on Google Play and the App Store, which shouldn't take more than a couple of days or a week.
