"I don't understand why I can cast some .mkv videos to my Sony Bravia TV and not others. I highly suspect it's the video format in the container but I'm not sure (is there an easy way to change it?)."

We're in a great chance to meet MKV videos, no matter we download them from online or get an MKV copy from DVD/Blu-ray discs. MKV is a popular format these days that allows enjoying high-quality HD videos over various devices, including TVs. However, many users find some certain MKV files not playing on Sony TV or Sony Bravia TV. So what's the matter? Read on to find the possible reasons and an easy and efficient solution to fix the MKV not playing error on Sony Bravia TVs.


Why Some Certain MKV Files Not Playing on Sony Bravia TV?

Though the official site of Sony TV claims that it supports MKV format, many times, when you play these files, you will encounter playback issues. Actually, it can be caused by various reasons as below.

1. MKV format/codec is not supported. MKV is just a video container, which can be encoded with a wide range of codecs, like HEVC, H.264, MPEG-4, VP9, DTS audio etc. While Sony TV has poor compatibility with some of the codecs, such as Dolby True Audio and DTS Audio, which will make MKV not playing on Sony (Bravia) TVs.

2. Media with higher bit or frame rate than specifications. Sony TV only supports MKV files in specific bitrate and frame rate, for example, 4K H.264 at 30fps/60fps, 4K/8K HEVC at 60fps, 1080p VP8 WebM at 60fps etc. If your MKV video is in higher bit rate or frame rate, MKV will goes unplayable, stuttering, dropping frames and so on.

3. MKV file is corrupted. MKV won't play if your MKV file is corrupted or the information in the container is wrong.

4. Incompatible USB and digital camera devices. Many users play MKV videos via USB or digital camera devices. If none of the above is true, it might be an issue of USB or digital camera devices, which are not compatible with your Sony TV.

Broadly speaking, MKV format/codec incompatibity lies in the major cause of Sony TV not playing MKV videos. Therefore, transocding MKV file is the the most effective yet easiest solution recommended by us.
