Update| Simple Steps to Convert MKV to MP4 Online/Offline
“Who can help me? I load MKV file into iTunes, but the video has no sound and subtitles.”
Answer :
iTunes is a multi-function software from Apple, which can play movie, music, TV shows… It can recognize playback video in .mp4, .m4v, .mov extension. But, why can't iTunes play MKV video? Then we have to mention the characteristics of MKV.
MKV uses AC3 audio coding; AC3 can’t be recognized by general Apple playback software. This is the reason why playing MKV with iTunes doesn’t sound.
So, how to solve this problem? If you can't play MKV directly on iTunes, then convert MKV to iTunes compatible format, what do you think?
In the next part, I will share you how to convert MKV file to MP4.

Part2: Why Choose MP4 as the Conversion Format?
MKV VS MP4
1. MKV supports FLAC as audio, but MP4 does not. But MP4 can also package lossless audio tracks (such as ALAC, although it is generally considered that ALAC is not as efficient as FLAC)
2. MKV supports subtitles in ASS/SSA format, but MP4 does not. The subtitles produced by the general subtitle group are in ASS format, so the inner subtitles are more common in MKV format.
3. As an industry standard, MP4 is generally better compatible with MKV on video editing software and playback devices. This is why vcb-s basically chooses the MP4 package for mobile-optimized video.
MP4 VS M4V, MOV
The M4V and MOV are very popular on Apple devices, but not the Android devices.
In conclusion, it’s up to you to decide which format to convert to, depending on your needs. I choose MP4 as output format due to its powerful device compatibility.
In the process of converting MKV to MP4, we may have many problems, such as the converted MP4 video doesn’t have subtitle. Don’t be worried.
On the one hand, make sure that the subtitles of the source video are built-in or file-attached.
If it is built into the video, it cannot be retrieved. At this point, you should find the source file before the conversion and export the embedded subtitles in the video player.
If the source file has been deleted, you can only search online and download subtitles of the same video.
If the subtitles are file-attached, it is recommended to use file search to search for the location of the subtitles (some videos and subtitles may not be in the same folder and may not be the same name). If not found, you also need to go online to search for subtitles.
On the other hand, if you don’t know how to download and insert subtitles into MP4 video, you can get help from third-party.
