When you play a movie, you find that it cannot be opened because some program doesn't support MKV format. Then you may wonder why is this happening and how to solve it.
The reason why you can’t play MKV can be caused by the lack of certain codecs on your device. Because of that, even though you can see MKV everywhere nowadays, some devices or programs still don’t support MKV format. So, you need to convert it to a more common format, such as MP4, a much more usable format that can be loaded properly on almost every device.
Today we are going to introduce you 2 free converters to help you convert MKV files to MP4.

Part 3. FAQs of Converting MKV to MP4
1. Can ffmpeg convert MKV to MP4?
Yes, you can convert MKV to MP4 with ffmpeg. But it might be a little complex for you to understand how it works, even though the most effective step is only a sequence of characters: ffmpeg -i my_movie.mkv -vcodec copy -acodec copy my_movie.mp4
2. Can HandBrake export MP4 from MKV?
If you only want a MP4 file after converting, HandBrake can help you with that indeed. However, it cannot convert your files to other formats, such as WMV, MOV, FLV. HandBrake does support most common multimedia files. But that is its supported input sources. For output formats, your options are MP4(.M4V) and MKV.
3. Does converting MKV to MP4 lose quality?
Most video converters do lose quality when you convert MKV files to MP4, maybe 1% or 5%. While re-encoding the MKV files to MP4, it is hard to avoid data loss entirely. But you can increase the resolution of images to make the quality of exported MP4 videos close to the original video.
