Which M4V-to-MP4 converter to choose

There's no definitive answer. The choice depends on many factors. Take into account how often you need to convert files, whether those are just single files or batches, what you convert – full-length movies or short videos. Online converters and freeware work well for small or single files or when you only infrequently want to change your videos’ format. If video conversion is something you need to do every day, the best approach is to get more flexible desktop software with advantages like stability and functionality – such as Movavi Video Converter.
