The conversion of the file 264 to M2V will allow you to edit a file using other software than before. The conversion 264 to M2V is particularly helpful in cases where you want to give certain features to the data in the 264 file, and all the programs that support the 264 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 264 file that you want to convert. Then select the target format (in this case M2V) and follow the instructions. Save the converted M2V file in the selected location. From this moment you can open the M2V file with all the programs that you will find here.
