Hello,

I recently used by underwater stills camera in video-capture
mode. The flash strobe is inoperative in this mode which results
in the clip made with ambient lighting - shifted towards
blue. I'm looking for a way to "filter" the resulting AVI clip
by some SW that can change the "white balance" of each frame.
Can anyone recomment such SW that runs under LINUX (FC14 in my case)?

If there is none, what SW can break an AVI clip into frames, save each
frame as a separate image and after I'll "batch process them"
with GIMP to combine them back into a video clip (possibly of
other format)?

TIA for any help,
kaza.

kdenlive might do the trick for you.

There are plugins that handle white balance and a great support forum on the site.

You might prefer Blender.

http://www.blender.org/

It has a fantastic video sequence editor that will export an avi file to an image sequence and recombine later. Alternatively, you could do some adjustment of white balance and a multitude of other things in the composition editor before rendering to a video file.
It might have a larger learning curve, but it might better suit your needs.

Hope this helps.

Cheers

I'd think there is a video editor that can color balance.

Or maybe vlc and copy it as you view it. http://www.dedoimedo.com/computers/videolan.html

Thanks for all the replies, I'll try these apps and see what works best.

Sorry it took me long to get back - 12+ hours working days, GF, SCUBA...

avidemux is easy to use and comes with a good selection of filters for applying simple effects.

OK,

after attempting to install kdenlive, blender, pitivi and avidemux
I only managed to complete installation of pitivi amd avidemux (on mt FC14 system).

The first two either couldn't start at all or started and then produced some strange erro
message.

The only two which I could start and load the AVI clip inti are pitivi and avidemux.

The pitivi has a list of effects but I can't see among them anything that looks like
white-balance. Can it be I don't have all filters installed? Runnung

"rpm -ql pitivi-0.14.0-2.fc14.noarch" I'm getting in the list the file:

/usr/share/pitivi/pixmaps/frei0r-filter-white-balance.png

but it's only an image file, what effect contains the white-balancing function?


Running "avidemux" I see a colors filter with white-balance capability, I'm currently
trying to figure out what values to configure it with.

I know that graphicsmagick can decode avi, but it cannot encode an avi. It can do everything imagemagick can do.
