Underwater Video Blue Hue

Using Moviemakeer, anyone know of anyway to get rid of the blue hue on
underwater video? Just spent the week and Cayman Islands and used my Sony
DCR-TRV33 underwater in a housing for dive video. Underwater, the reef
colors and fish were stunning. Upon editing the video, everything is rich
blue.

My dive buddy said to red tint the video and I downloaded the Pixelan free
sample to try that. Red tint adds a little color, but not much.

Anyone got any other suggestions?

Thank you.

Try removing the "Tint Red" effect, and instead apply the
"Contrast +30" effect from Pixelan.

If that improves your image, you can then try experimenting
with various combinations of Contrast and Tint effects to
see if you can make it even better.

Hi there,

I have 1.5hrs worth of underwater video that I have yet to edit. Its a more
Green-Blue hue here in England, but the procedure will be the same.

I have played a little with it and was not impressed with what I could do in
Movie Maker so switched it to a program called MovieDV Ver 6. With which I can
literally alter every parameter to do with colour, Alpha and Gamma channels. So
that's the way I will eventually go.

I have every transition and effect pack that goes for Movie Maker, not all are
installed on the new machine. The problem with all of them is that they use
fixed values...not the way to go, but it is the way Movie Maker is put
together...

MovieDV 6 can be purchased for US$69.00 from www.aist.de Its a lot harder to
learn, but once the penny drops all of the controls become quite obvious and
easy to use.

Filters for shooting underwater are usually red or orange. Adding red or
orange to your video will help (but not as much as adding a filter when
shooting the video)

Is the unwanted color blue...or cyan? According to the primary (red,
green, blue) and secondary (cyan, magenta, yellow) color tables, you
would neutralize tints as follows:

red removes a cyan tint (where red = magenta + yellow)
cyan removes a red tint (where cyan = green + blue)

green removes a magenta tint (where green = cyan + yellow)
magenta removes a green tint (where magenta = red + blue)

blue removes a yellow tint (where blue = cyan + magenta)
yellow removes a blue tint (where yellow = red + green)

orange (red + yellow) will remove tints between cyan and blue

Since you've already added some red tint, try adding some yellow to it
and see if that helps.

Why not take a snapshot of a typical single frame and use Irfanview or
Photoshop to adjust the color channels and see which combo neutralizes
the unwanted tint best, then use that combo on your video?

With Irfanview, use the RGB sliders as follows (all default to 0):
pure red = 255, cyan = -255
pure green = 255, magenta = -255
pure blue = 255, yellow = -255

You could also try viewing the movie in Windows Media Player 9 and
adjust the hue slider until you get colors resembling what you want.
