No ...
I will paraphrase these :
While both .mkv and .mp4 are video container formats (they hold video, audio, and subtitles), they are not the same format. An MKV file generally supports a wider variety of codecs, multiple audio tracks, and advanced subtitles, whereas an MP4 file is highly compressed and universally supported by almost all devices and web browsers.
Key Differences
Compatibility: MP4 is the industry standard for universal playback, meaning it natively works on iOS devices, smart TVs, and web browsers. MKV is an open-standard format that is fantastic for archiving but may require specific media players (like VLC Media Player) on some devices
Features: MKV shines when dealing with high-definition media because it can store virtually unlimited audio tracks, chapters, and high-quality subtitle files. MP4 limits the number of allowable tracks and formats.
Error Resilience: MKV has high error resilience, meaning the video can often still be played even if the file is partially damaged or corrupted. MP4 lacks this capability and can be rendered unplayable if broken
Quality & Size: The container itself doesn’t affect video quality. If the video and audio streams are identical, an MKV and MP4 file will be nearly identical in size and quality. However, MKV files appear larger when they bundle multiple audio/subtitle streams.
Youtube Video
as I've said write MKV @ the end of your post title in order to be evaluated, about subcoded/hardcoded sub titles .srt file has nothing to do w/ it ... That is different story ...
Now the MOD staff has only the access to decide what is best ...
