AVI

Avi file format

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992, widely used for storing video and audio data. It is supported by many media players like Windows Media Player, VLC, and editing tools such as Adobe Premiere and VirtualDub. The format uses a chunk-based structure to store audio and video streams, allowing for synchronization, and supports multiple codecs, though it lacks advanced features like metadata and streaming capabilities found in modern formats.

FLV

Flash Video file format

FLV (Flash Video File) is a container file format developed by Adobe Systems for delivering video and audio content over the internet. It is commonly used with Adobe Flash Player, supported by media players like VLC, and can be created or converted using tools like FFmpeg or Adobe Animate. The format uses a lightweight structure with metadata tags, supports streaming via RTMP, and allows for embedding of interactive elements like captions and cue points, making it suitable for web-based video playback.
