I'm using Pinnacle 14 to edit my videos. After I make a movie, I cannot go back to make changes because the file format is BOP or VOB. Will this application convert a BOP or VOB file to AVI?
No, the application developed by Keith Gilbert will allow you to convert only MOV files to AVI. To change your files format to AVI, I recommend you Convert VOB to AVI. It is a free and easy to use utility. Once you launch it, press the Open button to select your file and click the Convert option to start the process.
