video color saturation

Post by Lou »

Can someone tell me if there is available for free or a very low price a software
that is designed to enhance video color saturation. I know they have this
feature in ProTools 3 but surely some other company offers a simple bare
bones software for just this function.
It appears that all camcorders that use a single CCD suffers from low color
saturation especially in direct harsh light. Yes I realize you can simply
turn up the color on your monitor or television but if you can incode more
saturation in the video then no one would have to bother to make that adjustment
on their TV or monitor.

The NLE systems I am familiar with (FCP and FC Express) both have filters
for adjusting the color saturation and I assume that these are present in
all NLEs.

My Media 100 certainly has this capability as do the various Adobe Premiere
systems but the enquiry was for a very cheap 'add on' piece of software.

"Pro Tools"? I'm confused, this is a professional Audio application, not video.

However, My system, Final Cut Pro HD has one of the best colour correction
pallets available, AVID Xpress Pro has a half decent one also.
Premiere, forget it, you can't do any serious colour correction work in that
programme.

There is no such thing as a cheap filter, you have to know what you are doing,
if you don't know how to calibrate a broadcast monitor, then you are going
nowhere.

After I have finished editing a 1 hour programme, it will usually take me
5 full working days to go through and colour correct match, gamut levels,
crush blacks, legalize whites broadcast safe other colours etc etc etc...
There really is no easy way. Sounds like you need to read some books, a good
one is "Advanced editing and finishing in FCP" although a Final Cut book,
you will get some good ideas about colour correction.

In the meantime, if you want better saturation, try the following at the
shooting stage, which you should always do anyway, otherwise your footage
will look totally crap and washed out:

Use a very good Matte Box with a French Flag that extends about 7 inches
away from the lens, the crappy lens shade that came with your camcorder
doesn't count, throw it in the bin. The Matte Box, in my opinion is one of
the most underrated accessories you can buy and will improve your footage
50%, once you have read about the correct way to use it, if used incorrectly,
you might as well not bother attaching it in the first place.

Second, use a Polorizer filter, not a cheap Hoya one either, you will need
a good quality peice of glass, Formatt make a good one, so do B&W, cost around
£100, well worth it, this will saturate your colours and give your sky more
depth and 3-D quality, it really brings the clouds away from the blue sky.

Next, and most importantly "Exposure" don't use auto, auto is for lazy people
who complain that they don't have time to set it manually, if you use auto
your footage will ALWAYS be crap. I can adjust manually quicker than any
wedding videographer can flick the switch onto auto.

Once you are on manual mode, use an F-stop that is the prime quality setting
for your lens, usually about half way i.e. F5.6 to F8, if you go wide, sure
you get shallow depth of field, but you loose quality, contrast and saturation,
if you stop down, you get everything in focus, but the same loss of quality
in contrast and saturation.

Once you have your mid-point (prime quality) F-stop, you should use ND filters
to set the exposure, not the shutter speed or gain level, set your exposure
about 1 F stop under, this will give you deep colour saturation and it's
easy to bring the levels up a tad in post, but you can never bring them down.

Actually you can easily desaturate an image in post to any level of saturation
including all the way to total desaturation, a black and white image. You
can ramp up or down through saturation to give a transition from color to
b/w or vice versa.

Sorry Ned, I wasn't very clear was I? What I meant was that it is difficult
to bring overexposed footage down to the correct level of exposure, especially
with burn-out. Of course you can de-saturate any level, but as you say, if
it is overexposed too much, there will be a lot less saturation to bring
down. Does that now make sense?
