Deleting video from Whatsapp group chat is actually same as deleting messages in group chat, except in this case you will need to delete Video instead of message.
This are the simple things you have to do
1. Open WhatsApp and go to the group chat with the video you want to delete.
2. Locate the video, you’ll know it when you see it, because it usually starts playing once touched.
3. Tap and hold on the video.
3. Optionally, for multiple videos tap on more videos to select them.
4. Tap on the Trash can icon on top of the chat screen. Just like the name the Trash icon is symbolized by a Can.
