NEW QUESTION # 80
Which video formats does the <video> element in HTML5 support?
Choose 2 answers.

Answer: A,C

Explanation:
The HTML5 <video> element supports specific video formats that are compatible with modern web browsers and meet the requirements of open web standards. According to the HTML Living Standard and documentation from MDN (Mozilla Developer Network), the three main supported video formats for the HTML5 <video> element are:
WebM: An open, royalty-free media format designed for the web. It is supported in most modern browsers like Chrome, Firefox, Opera, and Edge.
MPEG-4 / H.264 (commonly using .mp4 file extension): A highly popular and widely supported video format across all major browsers including Chrome, Firefox, Safari, Edge, and Internet Explorer 9+.
"The HTML <video> element can support video formats such as WebM, MP4 (H.264 codec), and Ogg (Theora codec). Not all formats are supported by every browser, but WebM and MPEG-4 are the most universally accepted among major browsers." Formats such as FLV (Flash Video), AVI, and QuickTime (MOV) are not natively supported by HTML5
<video> and typically require plugins or external players, making them unsuitable for use with the <video> tag in modern web development.
