Covert videos to Android phones...

Well this method works for all mobile phones and portable media players (PMP).

One of the best free converters I found without ads or junk after install is Format Factory . 
The best things I love about it that I can rip whole DVD into single file and the lets you to pickup
language for audio and subtitles. Also it can convert download Youtube videos into MP3.

Start the program and from left menu click on Video bar. Select All to mobile.

From the models list I selected Google phone and 480x320 resolution since my mobile has HVGA resolution. To find out your screen size you can check your phone model at manufacturer website or PDAdb.net and GSMArena.com . 

If you have large SD card sure you pick a better sound quality when default.

Press OK.

In the new dialog select the files you want to convert and press OK. 

In the main window press start button and have a coffee while you will get all your videos converted.

And press the "Output folder" if it doesn't popup for you and simply copy all the videos into your phone

using PC suite or WiFi.
