Looking for free BATCH 3gp to Mp4 conversion tools WITHOUT quality loss.

Hi

I know there are many conversion tools available. However i am more interested in NO quality loss after conversion. Is there such a tool? I mean i do not what to do a re-encode because it will suffer a quality loss.

Thanks in advance

Hi
If the 3gp files contain H264/aac then it's OK to use mp4 "Pass Thru" preset with WinFF.

3gp is pretty dated now and it's for use by older smart phones with much weaker CPUs than today's phones. Please be aware that your 3gp files may have strange frame rates (15 fps or less is common) and the audio may also have severe limitations (22 KHz sampling). Even with no quality loss don't be surprised if your 3gp files look and sound bad once you convert them and watch them on a PC or a more modern phone.
