1. What is MKV?

MKV is the Matroska Multimedia Container developed by Matroska for video (with subtitles and audio); it is an open standard free container format that can hold an unlimited number of video, audio, picture, or subtitle tracks inside a single file. Yet, it is not as widely supported as MP4.

2. What is MP4?

MP4 is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. It is the most popular video format.

3. Can VLC convert MKV to MP4 without losing quality?

Yes. VLC can convert MKV to MP4 without losing quality if you set the output encoder to the same as the input. To do this, you have to open the "Video Codec" and "Audio Codec" tabs and specify the encoders based on the MKV file parameters. For example, if the MKV file uses H.264 video and AAC audio codecs, you need to set the output codec to H.264 and AAC respectively.
