How do I convert FLV to AVI on LetsConvert?

Upload your FLV file, select AVI as the target format, choose your preferred codec (e.g., MPEG-4, H.264) and resolution, then press Convert. The tool re-muxes audio/video streams without quality loss when using 'Lossless' mode, or re-encodes to a high-bitrate AVI if you need extra editing headroom.

Why would I convert FLV to AVI instead of using FLV directly?

FLV is optimized for web streaming and often contains H.264/AAC, but many video editors and legacy hardware media players don't support FLV's container. AVI is universally accepted by tools like Adobe Premiere, VirtualDub, and older set-top boxes. Converting to AVI also eliminates FLV's metadata overhead and can reduce file size while maintaining the same video codec, if you choose stream copy.

How does FLV to AVI conversion handle audio bitrate and video codec?

When you choose 'Lossless' mode, the conversion copies the original video and audio streams bit-for-bit, preserving H.264/AAC bitrate and resolution exactly. If you select re-encoding, the tool converts to a standard AVI with MPEG-4 Part 2 (DivX/Xvid) video and uncompressed or PCM audio, which may increase file size but ensures compatibility. Color profiles are retained as-is, and no transparency is lost since neither format supports alpha channels natively.

Is FLV-TO-AVI free to use?

Yes, FLV-TO-AVI on LetsConvert is 100% free with no registration or hidden fees required.
