Here are the steps:
First you need to download Youtube video to local file. I use
VideoDownloader Firefox Extension http://javimoya.com/blog/youtube_en.php
After install this plugin, every time I want to grab, I just
left-click the VideoDownloader icon and a pop up window will show me the URL where I can download the video directly. Save the video as .FLV file
So we got the FLV file. We need to convert it to 3GP/AVI file.
I use IMTOO 3GP Video Converter (www.Imtoo.com). Basically it can convert FLV file to 3GP, AAC, AVI, DIVX, MOV, MP3, MP4, MPEG, RA, WAVE, WMA, WMV, XVID.
Sometimes we need to edit the video. Still looking for a way to do that.
Purpose: able to edit, copy, cut, trim the FLV or 3GP, remove
watermark or simply over emboss it with larger text/block of colors.
