If you get lots of MKV files that you need to upload to video-sharing sites, you can convert your MKV files to AVI first. Here we will walk through to show how to convert MKV to AVI on Mac, free and online methods included.
Cisdem Video Converter is currently our best program for converting MKV to AVI on Mac. Thanks to its simple, no-frills interface and impressive features, you can easily turn MKV into 500+ formats (including AVI) in original quality.
VLC is an open source MKV to AVI converter that works on Mac and various platforms. It helps you transcode media files from one format to another. Only one MKV file can be converted at a time, batch processing is not supported.
But VLC is not as friendly to novices as Cisdem Video Converter. The latter has already set the best audio and video codec suitable for AVI, while the former needs to be manually selected, as not all codecs can be wrapped in AVI.
In spite of convenience, online converters have a size limit for uploading videos. Most of them can't convert videos larger than 200MB. But MKV video is famous for its high quality and large size. Generally, a full MKV movie should exceed 5GB, and online MKV converters don't support it at all.
To convert MKV dual audio to AVI on Mac, the only way is to remux videos without encoding. Remuxing puts video and audio streams from MKV to AVI container while preserving the actual encoding untouched.
FFmpeg is unable to automatically map all tracks. When using a common command line like ffmpeg -i input.mkv -c copy -copyts output.avi, the converted AVI file will merely map one video, one audio, and one subtitle track. You should add the command - "-map 0" to cover all tracks.
Avidemux is an open-source software designed for simple editing and transcoding tasks. It can remux dual audio MKV to AVI, FLV, MP4, and WebM on Mac. Besides remuxing, you can also change the output codecs to re-encode your media files.
