The conversion of the file FLV to 3GPP2 will allow you to edit a file using other software than before. The conversion FLV to 3GPP2 is particularly helpful in cases where you want to give certain features to the data in the FLV file, and all the programs that support the FLV 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 FLV file that you want to convert. Then select the target format (in this case 3GPP2) and follow the instructions. Save the converted 3GPP2 file in the selected location. From this moment you can open the 3GPP2 file with all the programs that you will find here.
