This Wiadomość wideo icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
This icon shows a typical comic speech bubble which indicates that someone is speaking - it's a large circle that has a little tail pointing to someone speaking. Inside the speech bubble is the icon for a video which is a rectangle with a small triangle on the front of it to illustrate a videocamera.
