If you prefer a command-line tool for batch processing or precise "min" control, use FFmpeg.

ffmpeg -i "jur153engsub.vid" -c:v libx264 -crf 28 -preset slow -c:a aac -b:a 128k -movflags +faststart "jur153_portable.mp4"

Use this when you cannot rely on the player supporting soft subtitles.

FFmpeg command (trim first 6 minutes, burn English subs):

ffmpeg -i JUR153.mkv -ss 00:00:00 -t 00:06:00 -vf "subtitles=JUR153.srt:force_style='FontSize=18,FontName=Arial'" -c:v libx265 -preset fast -crf 28 -c:a aac -b:a 64k JUR153_ENGSUB_6min_portable_hardsub.mp4

Explanation:

Resulting size: ~15–40 MB for 6 minutes at 480p.

In many universities, JUR stands for Jurisprudence or Jury/Judicial studies. 153 might be a module number (e.g., Introduction to Legal Theory). If your file is a lecture capture, it probably runs over 2 hours—hence the timestamp 020006.
