In most cases, the three steps above are enough for getting a great result with our MKV to MP4 online converter. If you want a specific video or audio codec for your MP4 output simply click on "Expert Settings" and choose the desired codec there. The available codecs are:

AAC

Choosing a codec by hand is only recommended if your target device cannot play the video created by our converter. Otherwise, the default settings give the best result. If you do not know which codecs to choose take: AAC/H.264.
