Handbrake - Freeware -
HandBrake
Video Conversion process for Droid
1. Select your source
2. Select your destination output
3. Right hand column select Iphone legacy
4. Under Video tab select H.264 as the "Video Codec", also under output settings chose MP4.
5. Personally I have been using 1200kbps as an average bitrate with great results.
6. Under Advanced tab change reference frames to 1, Subpixel Motion Estimation to 8
7. Click "Start" and your video will encode.
I have had great results with these settings above using that freeware program.
