The video stream has to be fully re-encoded: AVI typically carries MPEG-4 Part 2, and F4V expects H.264. That means a real transcode, so allow for processing time and a small generational quality cost.
Only one audio track will be kept. AVI can hold several, for example alternate languages, but F4V supports a single track.
F4V is built for streaming and progressive download, so the result starts playing before it has fully loaded, which the source format does not do well.
At 1080p, AVI typically runs around 7 Mbps while F4V sits near 6 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 2007, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts AVI video, stored in the RIFF AVI container since 1992, into F4V, which uses Flash MP4 and dates from 2007. The codecs each container accepts decide whether the picture has to be re-encoded.
AVI comes from Microsoft and dates to 1992. It usually holds MPEG-4 Part 2, DivX, or Xvid video with MP3, PCM, or AC-3 sound, and those streams set the ceiling for anything converted out of it.
F4V comes from Adobe and dates to 2007. It holds H.264 video alongside AAC audio, and every major platform needs a media player such as VLC to open it.
