From Jacek Pazera:
Pazera Free Video to 3GP Converter is an absolutely free application which converts the most popular video files (AVI, MPEG, MP4, FLV, and MOV) into mobile phone video format (3GP and 3G2). Application allows you to convert full movie or selected range only. You can limit output file size and set many parameters used by encoder (codec, bit rate, fps, sampling frequency, and resolution). The Pazera Free Video to 3GP Converter interface is very simple and user-friendly. To convert video files, just drag and drop them into main window and click the Convert button.
Version 1.2 includes Updated version of the FFmpeg encoder and aminor modifications to the source code and bug fixes.
Free application, plenty of customization, small file that didn't need to be installed before you use it.
None that I can think of, works great for what I need it for.
It depends what you are using this for, I think it is a must if you take lots of video with a cell phone, I took some videos with my Evo 4G today, and when I tried playing it with VLC media player the aspect ratio was correct, but there was no sound. When played with Windows Media Player, the aspect is 4:3 (even though its a 1280 X 720 resolution, 16:9), though the sound works, I couldn't stand the change in resolution. I decided to download this program, as it was free, though it really does have plenty more capability than it would first seem for a free app. I converted the files from 3gp to AVI, and it took literally three seconds or so (I chose to use the original stream), and mind you the file I converted was long, 3 minutes, 11,300 frames, 7,454kbps, 168mb original size. Only if you convert to another resolution would you have to worry about how long its going to take, it wont be super quick, but converting the same file to a different res using a different encoding took roughly 4 minutes on my AMD 5800 . Very satisfied, now I can enjoy the full resolution of the videos I have taken with my Evo, as well as sound, without WMP messing up the aspect ratio or making my videos horrible to watch! WMP compressed the video width, (I played side by side to see how it had redone the aspect ratio) so it really made it unwatchable for me, and I dont think its me being stupid and missing a setting on WMP to change the aspect ratio or change the video settings, I looked everywhere and couldn't find a way to make it look any other way but 4:3. If you have an Evo 4G this is a must, it made everything very easy!
Out of all the converters I used this does the job excellently. I managed to convert a 300mb movie in less than 20 minutes and the quality was excellent. The program works perfect on Windows 7 Ultimate
This is an excellent program to convert videos for any phone screen, I was able to tweak all the video and audio settings to the best possible picture and the result was perfect. And best of all its FREE
Very easy program to use. Took me no more than a minute to figure out how to get the right filesize out that i wanted. Did not crash even with several other programs running at the same time. No problem resizing 3gp files to fit on my phone.
next time add mp4
Very easy-to-use for spesific task program. Worked great on my pc running xp home.
Fast download/installation, delivers what it promises, fast conversion.
The interface needs to be more dumbed-down for the layperson.
* Fast installation. * Delivers what its name promises - of being a free video to 3gp converter. * Provides low/medium/high-resolution options for the output file. * Fast conversion - 400 MB takes around 5 mins.
