Howdy, I have a new Macbook Pro and over the years I have a lot of personal videos that are in various formats. I would like to convert them all into one format using the Macbook and have the videos in a format that is the most compatible with the most devices. I won't be doing any video editing, just converting the video and hopefully/maybe reducing the size a bit. What is the best program that I can use for this? I don't mind paying but do not want to invest a lot. What format should I convert to? Thanks for any feedback.
