mka to avi conversion is in most cases searched by users that are looking for a way to convert Matroska multimedia content (in this case audio .mka files) to AVI video. This makes sense only if you are interested in using the audio track in new or existing AVI file, which means video editors are your best option here, despite many multimedia converters supporting this.
MKV files and not MKA files are used to store video, so perhaps you might find better options under mkv to avi conversion.
