#1. M4V vs MKV: Compatibility

#2. M4V vs MKV: Video and Audio Coding
MKV supports more video and audio codecs than M4V. From a technical point of view, the difference between M4V and MP4 is the codec used. MKV can hold MPEG-2, MPEG-4, H.264, and H.265, as well as VP9, and audio in MP3, AAC, AC3, and FLAC formats. For M4V, it can only store MPEG-4 AVC and H.264. In contrast to MKV, M4V can’t store audio in FLAC format.

Neither MKV nor M4V automatically provides better video quality, but MKV files are often larger.
Both M4V and MKV are container formats and their video quality depends on the codec they used. In addition to the codec, the resolution, bitrate, frame rate, and other factors are related to the video quality.
M4V vs MKV: Which Is Better for Your Video
- MKV is generally the more flexible choice.
- M4V is suitable when DRM-free M4V is supported.
For video editing, MKV is a good choice since it is supported by most platforms and operating systems. You can also try the M4V format if the platform supports it. One thing you should remember is that the M4V file should be DRM-free.
For video viewing, you should pay attention to the video quality since high-quality video can provide you with a better viewing experience. Both M4V and MKV are container formats, and their quality depends on the codec they use and other format parameters. MKV offers more video and audio coding options and supports lossless video compression, which can preserve more image details and better video quality.
