What is a AVI file?
Audio Video Interleave (AVI) is Microsoft’s venerable multimedia container introduced with Video for Windows. It stores audio and video streams in interleaved RIFF chunks, allowing simple players to read sequentially from disk. While it supports multiple codecs, it lacks modern features like B‑frame timestamping and embedded subtitles. Released in 1992 to counter Apple’s QuickTime, AVI became ubiquitous on Windows 95 thanks to the Indeo and Cinepak codecs. The rise of DivX in 1999 rejuvenated AVI for internet sharing, but mismatched VBR audio led to sync headaches. Microsoft replaced it with ASF/WMV and eventually MP4, yet legacy camcorders and CCTV systems still output AVI.
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.

Frequently Asked Questions
How to open a AVI file?
Windows Media Player, VLC, and MPC‑HC open most AVI files. If the clip uses an obscure four‑character codec (FourCC), install the corresponding VFW decoder or remux to MKV with FFmpeg. Adobe Premiere Pro and DaVinci Resolve import AVI but may transcode on the timeline for GPU effects.
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.
