What changes when you convert WMV to AVI
The video stream has to be fully re-encoded: WMV typically carries WMV9, and AVI expects MPEG-4 Part 2. That means a real transcode, so allow for processing time and a small generational quality cost.
At 1080p, WMV typically runs around 6 Mbps while AVI sits near 7 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 1992, and browsers will not play it directly. It is best suited to archival or a dedicated player.
