БЫСТРЫЙ ОТВЕТ
Возможно ли конвертировать AVI в MKV?
Да - AVI конвертируется в MKV.

Вы можете сделать это прямо здесь с помощью нашего бесплатного конвертера - регистрация не нужна, и ваш файл будет удален сразу после завершения.

The fastest path is the free converter above (files are deleted after converting) or ffmpeg -i input.avi -c copy output.mkv on the command line. The result is identical quality at nearly the same file size - remuxing is not a compression step.

Зачем конвертировать AVI в MKV?

AVI cannot hold soft subtitle tracks, multiple audio streams, or chapters, while .MKV handles all of these natively. Most people remux rather than re-encode - they keep the existing video codec (DivX, Xvid, H.264) and gain the ability to attach selectable subtitles. MKV also stores variable frame-rate timing more accurately, which can fix sync drift present in some AVI files.

Способы конвертации AVI в MKV

MKVToolNix OPEN-SOURCE

Add your .avi in MKVMerge GUI and click Start multiplexing - streams are copied without re-encoding by default.

HandBrake FREE

Open your .avi, choose an MKV container preset, and click Start Encode - HandBrake re-encodes the video, so conversion takes longer than a remux.

Freemake Video Converter FREE

Add your .avi, select MKV as the output format, and click Convert.

Command line - FFmpeg CLI

Run ffmpeg -i input.avi -c copy output.mkv to remux instantly without re-encoding.

Об этих форматах

Качество и на что обратить внимание

  • Remuxing with -c copy (FFmpeg) or MKVToolNix copies video and audio data unchanged - quality and file size stay the same.
  • MKV supports soft subtitle tracks that AVI cannot; embed an .srt alongside your video by passing it as a second input to FFmpeg or adding it in MKVToolNix before muxing.
  • Re-encoding tools like HandBrake can shrink the file but take much longer and reduce quality - only use them if a smaller file is the goal.

Часто задаваемые вопросы

Does converting AVI to MKV reduce quality?
No, if you remux using FFmpeg with -c copy or MKVToolNix - both copy the encoded streams without modification. Quality loss only occurs if you explicitly re-encode.
Will the MKV file be smaller than the AVI?
Not from remuxing - video and audio data is identical, so file size stays nearly the same. To shrink the file you must re-encode to H.264 or H.265, which is a separate step.
Can I add subtitles during conversion?
Yes - FFmpeg accepts a subtitle file alongside the AVI input, and MKVToolNix lets you add subtitle tracks before muxing, embedding them as selectable tracks in the output .mkv.
Do AVI files larger than 2 GB work?
Yes - large AVI files using the OpenDML extension are read correctly by FFmpeg and produce a properly seekable .mkv.
