Converting WMV to FLV optimizes your video for different playback requirements. WMV (Windows Media Video) and FLV (Flash Video) use different container structures with different strengths.
WMV (Windows Media Video, introduced in 1999) uses proprietary compression. FLV (Flash Video, introduced in 2003) uses proprietary compression. WMV browser support: Limited (Edge on Windows only). FLV browser support: None (Flash Player discontinued).
The quality impact depends on the specific settings used during conversion. FLV uses compression that may affect quality depending on the chosen settings.
Typical WMV file size: A 1-minute 720p VC-1 video: ~10-20 MB. Typical FLV file size: A 1-minute 720p H.264 FLV: ~8-15 MB.
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.
