Amen. You need to edit video anyway so that someone else will want to
watch it. sitting through a 30 minute race as raw footage is boring
for everyone but the driver. Even a seven minute lap of the ring gets
a little long for most people. I've found I can make a decent race
video by concentrating on having a total length of three minutes. A
better video is an entire event, including some non-track stuff, about
five minutes long. You have to add titles to explain the sections and
perhaps some voiceover. The downside is that producing an edited video
five minutes long from an hour of raw video takes two or three hours
of concentrated work. Figure twice the editing time per raw footage
time. And that's if you're pretty good at it, have a good idea where
the good stuff is, and understand the software. Inevitably you'll find
that you've accidentally cut something you wanted to keep.
The best way to do it is find some kid that likes playing with video
editing and have them do it. I need to find another one, my video geek
moved. Don't pay them, at least not in money. An occasional meal is
good.
