| Description | MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. | Windows Media Video (WMV) is a file type that can contain video in several video compression formats developed by Microsoft. The original video compression format used in the file, also known as WMV, was originally designed for Internet streaming applications compared to RealVideo. |
| Technical details | Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. | A WMV file uses the Advanced Systems Format (ASF) container format to encapsulate the encoded multimedia content. While the ASF can encapsulate multimedia in other encodings than the WMV file standard specifies, those ASF files should use the .asf file extension and not the .wmv file extension. |

For one free MP4 converter, this is very good. When I add my MKV video into it, and choose MP4 output format, just click Convert, this converter ran and a little time, finished.
