AVS4Mac M4V Converter is the best M4V to MP4 Converter that provides two kinds of MP4 output formats for users-Same as Source for MP4 & Customized MP4 Video. Though both of the two formats produce .MP4 output files, they still have some differences.
Generally, the best output format is H.264 video with AAC audio in MP4 format. Because H.264 currently offers the best video compression available. And the profile "Same as Source for MP4" has chosen H.264 video and AAC audio by default. So uses can produce output videos with high quality. But as the parameters are the default, meanwhile users can't adjust the settings. While the profile "Customized MP4 Video" offers user DIY experience to set the parameters such as Video Size, Video Codec, Video Bit rate, etc. But sometimes most users don't know the best settings. So the qualities of output videos may be not that perfect.
Consequently, if users need high-qualified output and know less about the best parameter settings, the profile "Same as Source for MP4" is preferred. On the contrary, if users need high-customized output and know much about parameter settings, the profile "Customized MP4 Video" is another good choice.
