Is AVI an outdated format?

Largely, yes. AVI dates back to Windows 3.1 in 1992 and predates streaming, chapters, soft subtitles, and modern codecs like H.265. It still works as a local archive container, but MP4 is the better target for anything you plan to share or play on current devices.

Can smart TVs and phones play AVI files?

It's a gamble. iPhones won't open AVI at all, and smart TVs or Android players only succeed if they happen to support the codec inside, often aging DivX or Xvid. Converting to MP4 with H.264 video and AAC audio removes the guesswork.

How much smaller will my AVI get as MP4?

Typically 40-70% smaller at the same visual quality, because older AVIs usually carry inefficient codecs like Xvid or MJPEG. Re-encoding to H.264 or H.265 in an MP4 container modernizes the compression without a visible difference.
