FLV (Flash Video) was the standard format for web video streaming before the rise of HTML5 video.

When Should You Use VP8 vs FLV?

VP8 vs FLV: Key Differences

• •The core technical difference: VP8 relies on lossy compression whereas FLV uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: FLV does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: VP8 files typically range Comparable to H.264 at similar quality and FLV files Comparable to MP4 for legacy content.
• •Primary audience: VP8 is built for web video, open-source streaming, webrtc scenarios, while FLV focuses on legacy web video, online streaming — pick the format that matches your output requirement.

Advantages of VP8

• ✓The lossy nature of VP8 means file sizes stay reasonable while handling Web video, open-source streaming, WebRTC efficiently.
• ✓From mobile devices to enterprise servers, VP8 is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using VP8 thanks to its efficient compression.
• ✓VP8 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of FLV

• ✓FLV uses lossy compression tailored for Legacy web video, online streaming.
• ✓FLV is supported natively on virtually every device, browser, and operating system.
• ✓FLV files are compact and quick to transfer, even over slow connections.
• ✓FLV integrates seamlessly with all major web development tools and workflows.
