I might well have asked this before but if I did, i honestly don't remember, so I'll (potentially), ask again ...

Why is it, when I attempt to film with my digital video camera, (in my the "FLIP" HD cam), the film has lovely colors, but the video, when played back, makes the film look like a redddened eastman mess?

Are you referring to playback from the cam or your computer?

Does that mean it did look fine on camcorder's lcd when filmed,but look reddish when playback?

No, it already looked reddish when i watched it on the little screen on the cam. Usually what I'll do is use the tint fucntion in the program on the PC and do my best to "restore" the color to as close as i can. My video of the STAR WARS last battle on youtube is an example of that.

Did you try playing around with the white balance settings? May help a bit. [Wink]

Unfortunately, I have never ran across that fucntion on the camera, but that does intrigue me, as I never have looked at each and every fucntion of this camera. Worth a look.

Hi Osi,

Video cameras all need to be told what is white. White being a balance of red, green and blue, or cyan, magenta and cyan.

Just like different film stock is balanced to react to different light. 3200K for old school tungsten and 5600K for old school general daylight.

So many amateur cameras will auto white balance as they go with variable results. Look for a white balance switch which will lock to either 3200K or 5600K and try each setting. 3200K should be better with a halogen projector lamp.

More sophisticated cameras will allow you you point it at a projected white image and set the colour balance by pressing a button.

Maybe if you tell us the camera model we could look up the user manual.

It will definitely have a MASSIVE difference,for sure. [Wink]

Here's a screenshot of a beaten-to-hell&faded-to-death print just lying around. Taken with my phone in full auto mode (hence AWB)

 -

And the same print,same phone,but manually balanced to tungsten 2300K,which is as far as it will go.

 -

Still doesn't much help for the faded color,but will give a good ground if intended to do further color correction.

Ideally use a REAL camcorder with full manual control is the answer,or anything with enough control should help. [Cool]

I would have thought that if it was a screen as a viewfinder th a balance would be at least a little off on that whilst taking the movie. If not the camera can't be very good or has gone completely out of adjustment internally when processing it into the file.

https://en.wikipedia.org/wiki/Color_balance

Spent 2 years at college learning this plus 3 years on a production TV degree.

Good stuff to study.

Wikipedia is basic, but gives a good guidance as to where to go from there, should you be interested in such things.

I should add that if you are recording video in order to adjust or 'grade' the colour you should be recording in the highest possible lossless quality as many lower end domestic camcorders will record a highly compressed format that throws out a great deal of colour information.

Rob!

Thanks for that awesome information! (and all others that have posted as well).

When I did that STAR WARS scope youtube video ...

https://www.youtube.com/watch?v=LDcrYl9NeMA

... I had to add a good deal of green as well as a slight "cyan" to it in my digital, just to get it to represent what the actual color looks like, and it still didn't quite get it right. I wish I still had that footage, just to show how badly it recorded it.

Didn't know how bad to begin with,but that's really GREATTTTTTT looking print. [Cool]

Star Wars S8 scope,that's the dream for me. [Smile]

Yes, I am quite happy with it! [Smile]

At least, with that greenish hue added, the video can be salvaged as, you can't restore color to a video that didn't exist in the first place. Oh , some color, (as in cyan filters for eastman film prints), but not if the color is gone from the print, period.
