I bet the reason why a majority of people adopt MKV format lies in its multiple tracks, which could save several audio and subtitle tracks in a single video. Even if sometimes you bow to necessity to convert MKV to MP4 for playing on mobiles, desktops, HDTVs, game consoles etc., you still prefer to retain the multilingual subtitle streams. However, the reality comes that MKV subtitles always get messed after MKV to MP4 conversion using Handbrake, VLC or other free video converters. For example, closed captions go out of sync, random ugly fat gray illegible subtitles appear on the screen, subtitles complete mess all of a sudden and even subtitles not showing.
Why MKV subtitles messed up? It might be caused with a variety of reasons, such as the improper subtitle format. If you're trying to watch subtitles in Unicode format on VLC, it will be unreadable. Or free video converters like Handbrake disrupt the sync of subtitles when converting MKV to MP4. For that, is there any way to fix the messed up MKV subtitle and make them showing correctly?
100% Working Way to Fix MKV Subtitles Messed Up Error: The Key: Re-add external .srt subtitles when converting MKV videos to MP4 Try with a MKV Converter
When your Unicode MKV subtitles not showing properly in VLC after conversion, you can try to fix it by adjusting computer settings: go to Control Panel -> Date, Time, Language and Regional Options -> Regional and Language Options -> Advanced and under "Select a language to match the language version of the non-Unicode programs you want to use" you have to pick your target language. Reboot. However, there is a big possibility that the way won't work since MKV subtitle messed up error can be caused by various reasons.
