You <em>do not</em> want to reencode them, just want to connect/combine them into one as if they were text files. The reason you do not want to re-encode them is that it&rsquo;ll take a long time to process them and you might lose fidelity of the video if re-encode was not done correctly. The following instructions will just concatenate the files and produce a single file as an output in no time even on old hardware. (Ran this in FreeBSD 14.3 but you should be able to adapt it to a linux box or a Mac with homebrew).</p>
