What is a WEBM file?
WebM is a royalty‑free container designed by Google for the open web. It packages the Matroska profile with VP8/VP9/AV1 video and Vorbis/Opus audio, optimised for low overhead and HTML5 streaming. Announced at Google I/O 2010, WebM combined Matroska’s flexibility with On2’s newly open‑sourced VP8 codec. YouTube began offering WebM downloads the same year. Support grew as browsers added VP9 hardware decoding and will expand again with AV1.
What is a FLV file?
Flash Video (FLV) is a container that encapsulates Sorenson Spark, VP6, or H.264 video together with MP3/AAC audio and on‑screen data events for ActionScript. It became the backbone of early YouTube and news portals because the small header footprint yields quick progressive playback. Macromedia introduced FLV in 2002 with Flash Player 6, offering the first ubiquitous plug‑in‑based video experience on the Web. After Adobe’s acquisition, FLV evolved to support H.264 in 2007 but began losing ground once HTML5 <video> gained traction. By the end of 2020, Adobe disabled Flash, and most CDNs convert FLV archives to MP4 or HLS.

Frequently Asked Questions
How to open a WEBM file?
Chrome, Firefox, Edge, and Android open WebM natively. Safari plays WebM starting macOS 14 with AV1 hardware decoders. Older editors may require transcoding to ProRes or H.264 MP4.
How to open a FLV file?
Desktop apps like VLC or MPC‑HC open FLV seamlessly. If you encounter a Spark‑encoded clip, convert using FFmpeg: `ffmpeg ‑i input.flv ‑c:v h264 output.mp4`. Web players no longer stream FLV, so upload sites recommend remuxing to MP4 or WebM.
