The conversion of the file 3GP to OGV will allow you to edit a file using other software than before. The conversion 3GP to OGV is particularly helpful in cases where you want to give certain features to the data in the 3GP file, and all the programs that support the 3GP format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select 3GP file that you want to convert. Then select the target format (in this case OGV) and follow the instructions. Save the converted OGV file in the selected location. From this moment you can open the OGV file with all the programs that you will find here.
