MKV (Matroska video File) is a video container format that supports more than one audio and subtitle tracks at the same file. It is based on Extensible Binary Meta Language. It supports several video and audio compression formats. The difference between MKV file types with most other video extensions is that it is a container, not a codec.
Q1: - My KMPlayer doesn't play MP4 file. KMPlayer can't play an .mp4 file I just downloaded from YouTube. I tried to use other media players (VLC, GOM, WINAMP), but none of them works. So I downloaded the video again and again, which does not fix the KMPlayer MP4 file opening error neither. So how to solve the problem that KMPlayer can't play MP4 files?
KMPlayer (on Wiki) - A highly-praised free media player for Windows which can play a long list of video formats including AVI, ASF, WMV, AVS, FLV, MKV, MOV, 3GP, MP4, MPG, MPEG, DAT, OGM, VOB. Although it seemingly supports all video formats, we still fail to play the mainstream formats like MP4, FLV, MKV. Why?
MP4 is a container format storing video, audio and other data like subtitles, still images. Not all MP4 files are encoded with the same video formats. Some may be H.264 MP4 and some are HEVC MP4. Due to different codecs, sometimes you can play one MP4 video but can't play another with KMPlayer. Converting video to H.264 - the most idea format for playing in KMPlayer - is a higly suggested solution to fix 'KMPlayer can't play MP4 MKV FLV files' issue.
WinX HD Video Converter Deluxe is an easy-to-use yet powerful video converter. It can convert virtually all video files. Built-in hundreds of video/audio codecs, it can import and export MP4 (H.264/HEVC), AVI, WMV, MKV, MOV, FLV, 3GP, MTS, WebM (VP8/9) and other formats quickly. Level-3 hardware acceleration is the key technology it uses to deliver the fastest video conversion performance without lags, jerkys or other issues even though you need to handle a large-sized 4K MP4 file. It also helps retain a high quality (almost lossless) of the resulting file.
Surely KMPlayer is capable of playing .mp4, .mkv and .flv videos. But if your installed KMPlayer doesn't work or can't open MP4, FLV or MKV files, probably your computer lacks the codec to play these videos. So to solve the "KMPlayer doesn't play MP4" problem, you can try to activate Script Active X of Windows by doing as follows:
KMPlayer and VLC media player should have no trouble playing MP4, FLV, MKV videos. If your KMPlayer doesn't play MP4 Video, probably it was not successfully installed.

Or, go to Options -> Preferences -> Filter Control and check the Source Filters, Splitters, and Internal Video (and audio) Decoders.
Well, there are also many other media players that can play MP4 video very well if your KMPlayer still can't play MP4 after all those efforts, one of which available for free is 5KPlayer (for Windows/Mac).

If you've been ever been disturbed by the troubles of playing, editing, or sharing your 4K, HEVC, AV1, or MKV files, WinX is the go-to solution to fix all the video not playing errors and offers fast conversion from one video format to another with high quality.
When you upload a video, it will initially be processed in low quality. This process helps you complete the upload process faster. Once the upload flow is complete, your video will be available to stream in low quality, on a wide variety of devices.
Higher qualities, such as 4K or 1080p, can take more time to process. While this processing happens, your video may seem to be missing higher qualities for several hours. Once high-resolution processing is finished, higher qualities will be available on your video.
For instance, 4K videos are four times larger than 1080p videos. It can take four times longer for 4K quality to be available after an upload finishes. A 4K video with a frame rate of 30fps that is 60 minutes long can take up to four hours to finish high-resolution processing. A 4K video with a frame rate of 60fps will take longer.
The converter can handle a ton of formats, including MKV, WMV, MP4, MOV, and AVI. It also acts as a video to audio converter and offers multiple presets for this function. It supports up to 4K resolution. The free version of Allavsoft lets you merge or convert videos of up to five minutes in duration, but is still very usable compared to other more limited trial software.
Additional features include a screen recorder for creating your own video files and a built-in player that allows for playback and preview. One item not included in this client is a set of editing tools, which some users may miss.
It can download videos from a range of popular sites including Instagram, Facebook, YouTube, Twitter, Vimeo, Dailymotion, and YouKu.
