Convert/Sync MKV files to iPhone 4S

Though iPhone 4S seems more powerful in some respects, such as dual-core A5 chip, iOS 5, 8MP camera, Siri etc. But, according to a large number of reviews, it still can’t support more video formats, the most popular video format – MKV, can’t be played well.

MKV video is popular for its high-definition video quality. We may get it by online downloading or ripping from Blu-ray discs. It supports multi-track and multi-subtitle. This format is complex that only few media players can handle it. iPhone 4S isn’t lucky.

Therefore, if you want to watch mkv videos on iPhone 4S, you have to do some work in advance. I mean you should convert MKV to iPhone 4S. In my opinion, this is the best solution currently. First of all, a suitable MKV to iPhone 4S converter should be installed on your computer. Then you can follow the steps to realize it.

1. Run the iPhone 4S video converter and add your mkv videos. After you added your video files, you can also make some editing to get the effect you want, such as trim, crop, add watermark, replace audio, remove interlace etc.

2. The most important step. Choose output format for your iPhone 4S. Such as mov, m4v, mp4 etc. You should make sure the format can be supported well by iPhone 4S. For myself, i prefer h.264 mp4, this format is liked by most apple products. You also can try this format “iPhone – iPhone 4 MPEG-4 640*480 (*.mp4)“. It’s a preset for iPhone 4, it has the best parameters for iPhone 4S, what you should do is just choosing it.

3. Now, you can start the conversion.

There are many factors affect the conversion speed, i can’t tell you the exact time you should to wait. But if you use Nvidia video card, the conversion speed will much faster. Because this tool is designed based on Nvidia CUDA technology. Anyway, just wait patiently.

Once the process is done, transfer the converted video to iPhone 4S via iTunes, Then you can play mkv videos on iPhone 4S as ease. Have some fun.
