What to expect
- AVI is not a modern container - most encoders write MPEG-4 video inside it, producing files noticeably larger than MP4 at the same quality.
- FLV-to-AVI is a full transcode, not a container swap - each re-encode loses some quality, so keep the original
.flvif you might convert it again. - Older FLVs using VP6 video take longer to decode; FFmpeg handles VP6, H.263, and H.264 FLV streams equally well.
Frequently asked questions
Can I convert FLV to AVI without losing quality?
No - the conversion is a full re-encode, so some quality loss is unavoidable. Use the highest-quality setting your tool offers to keep it minimal.
Why is the output AVI file larger than the original FLV?
FLV typically uses efficient H.264 or VP6 compression, while AVI usually holds MPEG-4 video, which is less efficient at the same quality level.
Should I convert to AVI or MP4?
MP4 is better for almost every use case - smaller files and wider compatibility. Choose AVI only when a specific tool requires it.
VLC shows an error when converting my FLV - what should I try?
Try FFmpeg instead; it handles unusual FLV audio tracks such as Nellymoser or ADPCM that can cause VLC's converter to fail.
