Converting FLV to AVI optimizes your video for different playback requirements. FLV (Flash Video) and AVI (Audio Video Interleave) use different container structures with different strengths.
FLV (Flash Video, introduced in 2003) uses proprietary compression. AVI (Audio Video Interleave, introduced in 1992) uses proprietary compression. FLV browser support: None (Flash Player discontinued). AVI browser support: None.
The quality impact depends on the specific settings used during conversion. AVI uses compression that may affect quality depending on the chosen settings.
Typical FLV file size: A 1-minute 720p H.264 FLV: ~8-15 MB. Typical AVI file size: A 1-minute 1080p DivX video: ~20-40 MB; uncompressed: ~3 GB.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
