I've posted a link to a site run by a friend of mine, Chris Anderson, in
the past (www.darklightimagery.net/). He's the guy I told you about who
took the outstanding pictures of Camps Gulf cave, in Tennessee (and many
others) that was featured in National Geographic Magazine, the one with
the largest cave chambers in the eastern U.S.

Chris and his group of merry cavers have been mapping the Webster Cave
Complex in Breckenridge County, Kentucky since I met him in college,
about 22 years ago. He has produced a short film about their efforts,
which includes many of the outstanding images he's taken of the cave
over the years. I was speechless when I first saw it. I've been in the
cave with him several times, and it is truly one of Kentucky's secret
treasures. This short film is worth the watch, and I encourage anyone
interested in caves to watch it at the link below, if you can. It is a
streamed video, so it helps if you have broadband, though it may also
work with a slower connection (although I make no guarantees).

Enjoy,


George

Thanks George

You found me a repository. I've been shrinking my 'stuff' down to 16 min
& 16 mb - the limit on youtube is 10 min (but filesize is no grave
limit), so I'll go back to Movie Maker.
I'm not sure weather I use flashplayer right, but as for the imagery of
your friend I miss the abillity to blow the pictures up.... I could
venture down those caves for the music alone thou!

You're welcome. Are you making .avi files or .mpg files. Also, what
codec are you using. When making an .avi file, I usually use the divx
codec, because it is very configurable, and allows many frame sizes, which
affect the file size considerably. It also has presets that allow you to
choose parameters on the fly depending on your usage (high resolution v.
medium or low resolution). Another codec I use for .avi files is xvid.
I'm not used to using it so much, but I understand that it makes a good
video with a low file size.

Movie maker makes these considerations superflous for a casual user like me,
but I'll have to look into it at some time. One problem I cann't seem to
deal with is my expectations as to reduce file-size by ie discarding any
soundtrack. But the repository, and the max filesize (100 mb)/10 min video
obsoletes that question too.
I'm uploading as we speak. 8 minutes of a 30 mb file sampled at 520 kbps
(sorry Jo). The quality seems to provide a full screen picture where you
don't notice the pixelation. I'm not sure what my own connection will say to
these numbers - up- and download numbers for one's connection are different,
and the ip makes sure that you know the heaviest number though that may not
be the numbrer you need to know about - they catch me faster than I care to
learn about how to dodge this sort of confusion..

The stream I've video'ed is probably man-dug. I come to think of this as I
watch a broad floating stream narrow toward it's discharge into the other
(very straight and boring) channal carrying discharge from other springs.
There's no natural meandering, and I have a hard time believing that the
steep soil-walls/brinks would have survived 10.000 years of this swift
current - but it's a fish's heaven none-the-less, as far as I can tell.

I hope that some of you will enjoy the bumpy ride.

(I've watched a snip - I suppose that my connection down-samples cos' the
quality is not what I sent ;o(

I can't recommend any mpeg1 or 2 setting for you, as I only uses those
for very large video files that I plan to burn on dvd.

Chris is one of the best cavers I know, and definitely the best equipped.
He is a great photographer who has won many awards.
