When AVI to FLV still matters
AVI is an older video container often found in archives, camera exports, screen recordings, and legacy Windows workflows. FLV is a Flash video format. Most modern platforms prefer MP4 or WebM, but FLV can still matter when you are preserving older assets, supporting a legacy player, or working with a system that specifically asks for Flash video.
AVI vs FLV
| Format | Best for | Compatibility | Practical note |
|---|---|---|---|
| AVI | Legacy Windows video, old exports, and archive files | Works in many desktop tools, less ideal for the web | Often converted to modern or workflow-specific formats |
| FLV | Flash-era video systems and legacy playback workflows | Limited modern browser support | Use when a system specifically requires FLV |
Quality and compatibility
Video conversion can change codec, file size, resolution, and playback support. EchoWave focuses on creating a practical FLV output for workflows that need it. If your goal is modern web playback, uploading to social platforms, or sharing with most users, MP4 is usually a better target format than FLV.
