Step 1: Run this Mac MKV to iPhone 4 Converter, and load MKV files to it
This application supports batch conversion, so you are allowed to add plenty of MKV files to convert at a time. More than that, if you need join all the added files to be as a single file, you can tick off the checkbox “Merge into one file”. In that case, there will be no intervals when you play them back on your iPhone 4 OS.

Click the pull down menu at the end of “Format”, and then tap on “iPhone” preset, afterwards, all the iPhone format profiles in the MKV to iPhone 4 Converter for Mac will appear as below. You can select one according to your own requirements. Here I chose “iPhone H.264 640x480 (*.mp4)” for instance.

Step 3: optimize video and audio settings
Click “Settings” button, then the following interface will show up. You can adjust all the V/A parameters to optimize the output file quality for your iPhone 4, including codec name, bit rate, aspect ratio, frame rate, sample rate, and audio channels. To change these settings, you should learn iPhone 4 supported video formats in advance, and strictly follow them while doing adjustment, or the final MKV files may be not playable on your iPhone 4G.

Video formats supported:
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
