However, before converting your current video file to MKV format, it’s worth noting that a video’s quality cannot be improved if the quality is already minimal, perhaps a little blurry or out of focus. Instead, you would need to recapture the video, perhaps saving it in a different file, to begin with, or shooting on a higher quality camera or mobile device.

Why convert your video format to MKV?
MKV files contain higher-quality audio and unlimited audio, video, picture, or subtitles in a single file. This makes MKV files ideal for movies, long documentaries, or videos that contain built-in subtitles. Essentially, MKV files are your go-to for large clips, ranging from twenty-minutes to multiple hours of blockbuster-worthy entertainment.
Compared to MP4 files, longer videos perform better as an MKV file. This is due to the codecs - the MK4 codecs are much more accurate and reliable - your go-to partner for longer video clips and features.
However, to play an MKV file you will also need the codecs that go with these. If you do not have the codec then you may not be able to play the clip. When sending MKV files via email, uploading to the cloud, or via pen drive, it’s important to attach these codecs as well.
Further benefits of MKV files will be discussed below.
What are the benefits of using the MKV format?
There are several benefits of using the AVI file format, but these include:
  • High-quality audio and video
  • Unlimited audio, video, picture, and subtitles
  • Best for long clips, TV Shows, documentaries, and movies
As previously mentioned, one of the main benefits of MKV files is fantastic high-quality (audio and video), especially for longer clips or videos. For this reason, MKV files are commonly used for short and long movies, TV Shows, documentaries, and anything in-between. Similarly, MKV files have unlimited audio, video, picture, and subtitles. This allows content creators to add all sorts of clips, transitions, content, and subtitles (key for movies) without sacrificing on quality, not later compressed, with some quality lost as opposed to other video file formats.
Furthermore, MKV files are compatible with many different programmes and playback devices, much like a disc (Blu-ray or regular). In fact, often these files are burned to MKV format on a disc - maintaining the high-quality output for easy distribution.
Are there any downsides?
As with all file formats, you’re going to run into a couple of downsides - that’s just how it is. In this instance, MKV files are often large, very large. This is because the file contains numerous pieces of content, subtitles, video, audio, and image, all at a stunning high-quality.
Likewise, the finished product is not compressed to the extent of other files, e.g., MP4 or MOV. Also, if MKV files are movies, long documentaries, or episodes of TV shows then sending these clips via email may not be possible, Instead, you may wish to burn the file onto a disc for playback on a device. You can also upload these to the cloud, if you have space, but be wary that this could take quite some time.
Buy premium
As previously discussed, HD Convert provides two methods of video conversion, including MKV: free and premium. The free version of HD Convert places a quality limit (just below HD) on all videos and images. Also, there is a watermark on all images and videos, unless a premium package is purchased.
However, unlike other image and video conversion subscription services, HD Convert operates via a purchase premium package. Users buy what they need, whether that’s three conversions, ten, or twenty. The most basic package begins at $4.99, unlocking HD and Ultra HD quality. Not to mention removing the watermark.
Likewise, all uploads, whether MKV video conversions, images, or audio are saved on the HD Convert servers for 24-hours. If your connection is to drop during the conversion process, you can resume it right away without interruption once your connection is re-gained. This is available for both the free and premium versions of HD Convert.
So, the big question: Who is HD Convert premium for? As MKV files are typically used for movies, documentaries, and TV shows, we’re going to go ahead and guess that watermark would be a burden. Also, you’ll likely want the highest quality video, audio, pictures, and subtitles. If this is you, then HD Convert premium is the obvious choice.
