Does anyone know where I can find a decent video format converter, that will let me convert FLV files to 3GP. Preferably an open source one which leaves no stupid watermarks behind half way through the video, or doesn't butcher the sound quality too much.

EDIT: And yes I googled it, tried about 5, all had watermarks.

ffmpeg

This.

Although, if a command line interface scares you as much as it does me, you'll want to get one of the GUIs for it.

FFMPEG burns my face.

Any good GUIs to get?
I tried one called Avanti, but it failed, wasnt any drop down options which there should have been. :S

Or a converter thats easier to use

That's because you need to get the codec libraries for them.

Hmm.. I found a program called VLC Media Player, it can convert, but I cant see how.. I found a conversion button, but there isnt a 3GP selection. Anyone know how I can get it? Its VLC Media Player 0.9.2

EDIT: Turns out I can change it to the acc file for iPods, so I could just have it on my iPod instead. Its a music video so I guess it is a good idea

Its saving it as a .ps file... I told it to convert it to .aac.. -.-

Actually, on the subject of ffmpeg, could someone suggest a good frontend for it in Ubuntu?
My laptop can't even handle 640x480 video, so I need to lower the quality of quite a lot of stuff :<

VLC isn't for converting, and if you'd found it in a normal way you'd know that.

If you've been given a program that works perfectly fine and just isn't "pretty" enough for you, you really don't deserve help. Pay for a converter if you want it pretty.

If you need GUI use MediaCoder or S.U.P.E.R

Actually you can use VLC to convert media files. There's a tutorial on how to do it here.

Whether or not you can use this for 3gp I really don't know, as I have no prior experience with that file format.

VLC rocks, but as my all around media/everything player. Never tried converting with it.
