Convert Android .3GP movies to .MP4 on windows

Hardly any software works well with .3GP movie files. So, with this collection of movies accumulating in my phone sync folder I needed something to convert them into formats that are more useful (like video editing software or upload sites). So, here’s a little quick and dirty solution for batch converting these files on a Windows machine – with pretty high quality I might add. Of course there are a lot of other things you can do with ffmpeg, so be sure to explore…

Step 1. Install cygwin command line so that you can use the bash shell to loop through stuff on Windows.

Step 2. Download the *static* binaries for windows from this site http://ffmpeg.zeranoe.com/builds/

Step 3. You are lazy like me, so copy those binaries right into the /bin directory in cygwin so they are available at the command line without any salutes.

Step 4. Put the script below into the same /bin directory because you are lazy


#!/bin/bash
# jcz 25-may-12
# filename: 3gp2mp4.sh
# converts all 3GP video files in the directory
# where it is run. Logs all file contents
# and errors to a text file in the directory
# in which it is run
#

Step 5. Using cygwin, change into a directory containing some .3gp files you want to convert and run it. You will send up with one .mp4 file for each .3gp file you started with in that directory.

$ 3gp2mp4.sh
Welcome, john.zastrow. I’m running in /cygdrive/c/Users/john.zastrow/Videos/Phon eVids and I will convert all 3GP phone videos to here mp4 files.

I see the following files to convert. I will write them down for you now
VIDEO0001.3gp VIDEO0013.3gp VIDEO0025.3gp VIDEO0037.3gp VIDEO0049.3gp
VIDEO0002.3gp VIDEO0014.3gp VIDEO0026.3gp VIDEO0038.3gp VIDEO0050.3gp

#

Please review the file Fri_2012-05-25_17_06_28_3gp_convertlog in this folder whe n I’m done.
************* RUNNING ****************
Moving files: ls VIDEO0001.3gp.mp4 VIDEO0002.3gp.mp4 VIDEO0003.3gp.mp4 VIDEO000 4.3gp.mp4 VIDEO0005.3gp.mp4 VIDEO0006.3gp.mp4 VIDEO0007.3gp.mp4 VIDEO0008.3gp.mp 4 VIDEO0009.3gp.mp4 VIDEO0010.3gp.mp4 

#

You’ll also get a very verbose log file of what the starting files looked like (stat) and what ffmpeg saw and did. I do love my log files 🙂
