Looking for an MKV Converter?

MKV (short for “Matroska Multimedia Container”) is a free, open-source multimedia container format. An MKV container can hold an unlimited number of video, audio, image, and subtitle tracks in a single file. This is why it enjoys immense popularity with movie enthusiasts who store their vast film collections in this format.

You can take advantage of the VLC media player as an MP4-to-MKV converter for free. All you need to do is follow these steps.

1. Install and launch VLC.
   Download VLC

2. Go to Media > Convert / Save.

3. Click Add and find the video file you want to convert.

4. Select Convert / Save in the lower portion of the interface.

5. In another dialog box, click the Wrench icon, choose AVI in the Encapsulation tab, and click Save.

6. Hit Browse and specify a name for the output file. Make sure the name includes the .mkv extension.

7. Click Start to convert your video to MKV.

You can also use MP4-to-MKV converter online services, such as cloudconvert.com or convertfiles.com. However, keep in mind that most of these services have restrictions on the number and size of files that can be converted at one time.

Although both formats are popular, MP4 is supported by a wider range of devices, systems, and platforms. If you consider watching videos on a smartphone or tablet, MP4 is a much safer bet. If you play them back using media applications like VLC and 5KPlayer, MKV can be a sufficient option.

No, MKV files are usually larger than MP4 files – owing to the fact that MKV supports multiple audio as well as subtitle tracks and has other additional features. This doesn’t affect quality as both MKV and MP4 videos deliver roughly the same picture. However, you may want to use MP4 files or convert them to MKV and compress them with a dedicated app like Movavi Video Converter.

This may be due to video and codec issues, damaged or corrupt files, technical glitches, or many other problems. Here’s what you can do to fix it.

1. Open VLC and go to Tools > Preferences.

2. Select All in the lower-left corner of the program window.

3. Click Input / Codecs.

4. Choose Video codecs and then FFmpeg.

5. In the right-hand portion of the interface, find Hardware decoding and select the Disable option next to it.
