Why convert MKV files before uploading to YouTube?

MKV files can contain multiple audio and subtitle tracks or codecs not supported by YouTube. Converting ensures the video uses compatible formats and simplifies track selections for smooth playback on the platform.

Will converting from MKV lower my video quality?

Converting usually involves re-encoding, which can reduce quality compared to the original MKV file, especially if lowering bitrate or resolution to meet upload constraints.

Can all MKV features be preserved after conversion?

No. Some MKV features like attachments, advanced subtitles, or chapters might not transfer to the output file, limiting their functionality on target platforms.
