MKV File Size Calculator
Here’s a comprehensive table with important aspects to know about MKV file sizes and the factors affecting them:
| Category | Description |
|---|---|
| File Extension | .mkv |
| Full Form | Matroska Video |
| Compression | MKV files can use different compression methods to reduce file size without losing much quality, including codecs such as H.264, H.265 (HEVC), and VP9. |
| File Components | MKV files can contain multiple video, audio, and subtitle tracks, which can increase their file size depending on the number and quality of these components. |
| Video Codec | Commonly used video codecs include H.264 (high compatibility) and H.265/HEVC (more efficient compression but higher processing requirements). |
| Resolution | Higher resolutions (e.g., 1080p, 4K) will generally lead to larger MKV file sizes. |
| Bitrate | Higher bitrate generally means higher quality but results in larger file sizes. |
| Audio Tracks | Number and quality of audio tracks (e.g., stereo vs. surround sound) can affect file size. |
| Subtitles | Multiple subtitle tracks can be included but typically have a minimal impact on overall file size. |
| Container Features | MKV allows for flexible storage of metadata, chapters, and other data that can slightly affect file size. |
| Encoding Settings | Compression and encoding settings (e.g., constant rate factor for x264/x265 encoding) influence file size. |
| File Size Impacting Factors | Length of the video, encoding options, video frame rate, audio compression formats, and embedded data. |
| Comparison with MP4 | MKV generally offers more flexibility and supports more formats, but files tend to be slightly larger than similarly encoded MP4 files. |
| Supported Platforms | MKV files are widely supported across platforms and media players, including VLC, Kodi, Plex, and more. |
