How to convert and copy videos and music to Kindle Fire
STEP 1
Download Miro. (it's free and open-source)
STEP 2
Connect your Kindle Fire with a USB cable to your computer and it will appear in the ‘Connect’ tab in Miro.
STEP 3
Drag any videos, movies, or music to the Kindle Fire in the Miro sidebar and they will automatically convert to the right size and format and sync.
That’s it! Works on Windows, Mac, and Linux.
How to Watch Videos you Sync to Kindle Fire
Videos that aren’t purchased from Amazon will be viewable in the ‘Gallery’ app on your Kindle Fire, not in the ‘Video’ tab.
Miro will convert almost any video format for the Kindle Fire, including AVI, MOV, WMV, MKV, WebM, FLV, and more.

Since Amazon doesn't make it very easy to get non-DRM videos onto Kindle Fire, without an app like Miro, we put together this quick guide. Hope it's helpful! There's also a blog post on the Miro blog that explains how to convert videos for Kindle Fire.
