MKV File

File extension .MKV
CategoryVideo File
DescriptionMKV is not a multimedia compression format, but rather a container format, which incorporates various types of multimedia. Mostly, such files contain audio, video, textual information (subtitles), etc. ñ elements, which may use completely different encoding patterns. MKVís biggest advantages are easy online sharing, low error rate, dissection of files into separate chapters, switchable subtitles, switchable audio- and video tracks, etc. Mostly, MKVs consist of open source elements, and they can be played in a vast number of players on nearly all existing platforms.

AVI File

File extension .AVI
CategoryVideo File
DescriptionAVI is a format intended for combining and synchronizing audio and video during playback. AVI is used by a variety of players, including KMPlayer, Windows Mediaplayer, VLC player. Uncompressed AVIs show excellent video/audio quality and do not necessitate installation of any additional codecs. However, sharing these files is very difficult because of large file size. XvidX and DivX codecs pretty much solve the problem, as they ensure effective compression that will not affect quality. Many users choose to change AVIs into other compact and versatile file types.

My living room TV from 2012 only plays AVI from a USB stick — converted my entire MKV library and everything plays back without stuttering now, even the 1080p files.

Needed AVI output for a legacy DVD authoring workflow that refused to accept MKV containers. Conversion was clean and the resulting AVI files burned and played correctly on a standalone player.

I have an old media player in the car that only supports AVI. Batch-converted 30 MKV episodes of a series and they all load and play fine on the device with correct audio sync.

Convert MKV to AVI — Frequently Asked Questions ▼

Not necessarily. If the video codec inside the MKV (e.g., H.264) is compatible with AVI, the video stream can be copied without re-encoding, preserving full quality. If re-encoding is required, there will be a small quality loss. Audio is typically re-encoded from AAC to AC3 or MP3 for AVI compatibility.
Older DVD players and many smart TVs do not support the Matroska container (.mkv). AVI has much broader legacy hardware support. Converting MKV to AVI makes the video compatible with these devices.
AVI has very limited subtitle support. External subtitle tracks (SRT, ASS) from the MKV will be lost in the AVI output. If subtitles are important, burn them into the video during conversion using the desktop converter.
No. AVI supports only a single audio track per file. If your MKV has multiple audio tracks (e.g., multiple languages), only the primary audio track will be included in the AVI output.
The online converter accepts files up to 50 MB. For larger MKV files, use the desktop Total Video Converter, which has no file size limit.
Use the desktop Total Video Converter: TotalVideoConverter.exe C:\mkv_files C:\avi_out /ConvertTo avi /ProcessRecursively
AVI is an older container format that lacks modern codec support. For long-term archiving, MKV or MP4 with H.264 are better choices. Use AVI when you specifically need legacy hardware compatibility.
 

 

Convert MKV to AVI Online

MKV files hold high-quality video with multiple audio tracks and subtitles — but older TVs, DVD players, car displays, and legacy video editors only accept AVI. Converting MKV to AVI repackages the video content into a widely compatible container without re-encoding quality loss where possible.

What Is MKV?

MKV (Matroska Video) is a flexible open-source container format that can hold any number of video, audio, subtitle, and chapter tracks in a single file. It supports virtually any codec — H.264, H.265, AV1, VP9, AAC, DTS, TrueHD — making it the preferred format for high-quality video downloads, Blu-ray rips, and anime releases. MKV is not widely supported by older consumer electronics, which is why conversion to AVI or MP4 is often needed.

What Is AVI?

AVI (Audio Video Interleave) was introduced by Microsoft in 1992 and became the dominant PC video format throughout the 1990s and 2000s. Despite its age, AVI remains the most compatible format for older consumer electronics: DVD players, car media systems, and early-generation smart TVs all support AVI where they refuse MP4 or MKV. AVI uses DivX, Xvid, or MPEG-4 video codecs and MP3 or AC3 audio, all supported broadly across hardware and software.
