Probably not, videos can be very messy, I seem to recall having to copy a lot
of wistia videos about at that time and had to resort to manual tricks without
httrack.

In other cases it's even harder to figure out, and you're much better off just
finding some software or service that can explicitly handle them (in their
current version), if it exists.
