HELP! How do i color correct an area of a video?

Hey
Im new to after effects cs4. I made a time lapse video of the sky. However, the sky is to bright and you can't really see the clouds very well. I would like to change the 'levels' of the sky, but not the buildings at the bottom of the video. So only half of the video will have colour correction on it. How do i do this???? Thanks!

The gist is simple:
Create an adjustment layer.
Draw a mask on the adjustment layer.
Apply the color-correction effect to the adjustment layer.
The devil is in the details. For example, if you need to animate the mask, you may have some rotoscoping to do.
Here's a video that shows how to do this in a case where the item to be color-corrected is moving:

This is actually a very basic compositing question, so I'm going to strongly recommend that you begin at the beginning and work your way through the getting-started learning materials.

How to best color correct image

Hi,
I earlier asked a question whereas I was having problems with color consistency from PS to ID. After resolving that I've run into another issue:
In trying to figure out a way to put an image in ID in a specific set of red cmyk numbers. I've come up with two solutions, but each has a set of problems. Both are CMYK.
The image on the left is a flattened black and red image (halftone) tif from Photoshop (the filter used flattens it). IT looks pretty god but If I try to adjust it with the correct red numbers, the black isn't neutral and gets a color cast, or I'm afraid it will in the printing process.
The one on the right is a black and transparent tif from Photoshop that has been place over a red background (already in ID). Why does this 2nd one appear to be greyed?
(I think I need to learn to fine-tune the color correction on the left one, but not sure which controls to use).
Thoughts?
No sooner did I post this, I read about someone else talking earlier about using the Multiply effect ( I didn't realize you could do this in ID), I tried it and got a more integrated image which is what I wanted. Neat. Now, are there any printing repercussions during the printing process with this effect that I need to worry about, or WYSIWYG? ( I still need to tweak the contrast I know, but at least the red is right.)

I just wrote a huge, even more convoluted post trying to answer your questions, which I'll save for later because it may be moot. I'm thinking aloud here to try to clarify:
We'er talking about 2 issues here, the greyness of the blacks and how they look on the surface and the color cast that may occur, is that right?
Let me say that I initially used a 3rd party filter called "Ghost" (can only be used on RGB images). I use it on B&W images as well as color. That takes out all white information and leaves all transparency in various densities. Only a solid black has no transparency. Then I converted to Robin's SWOP Heavy. She is using black & white photos, not transparent images.
Then came along your process.
I took those images that were over cream (in Robin's workflow...I didn't see anything wrong with these images intially), then put them over red and sure enough got that greyed-out look, which is only noticable over red, but if I use them may show up in print that way, which leads me to believe I need to use your process, as the quality of the blacks needs to be consistant.
Left is Robin's profile, right side is with "Multiply" applied. Which leads me to believe that I need to re-do all my images as per your ideas. I thought black would be black. Guess not. I'm not sure if the end result of using your process is the same as using multiply or not but it looks the same and is consistant.
All that being said, what again should be my images profiles and ID file be?
this is what they are, ..and I thought they were Blurb's but I screwed something up there too...
Images..don't remember If I need to convert!!? I think so then what's the point? UGH:

How to save Color Correction Setting as a file?

I'm new to premiere pro cs6. Is it possible to save a color correction setting as a file? So I wont have to manually adjust every Video file I insert to the timeline to match the previous. Help Please. Thanks.

To expand on Jim's comment, as this is a semi "non-destructive" editor, meaning the things you "do" to a clip don't actually change that clip on the hard-drive but are stored in the project files for that clip until you export the project ... this program is built around storing the details of the effects and then applying them in real-time to footage as you edit it.
So use that capability. Build up your modifications of the original footage in layers and that way you can turn on/off various parts of your "looks" as you want and as it makes it easier to work. Planning out the layers of effects/changes is a good part of mastering the tools available in PrPro.

How to keyframe color-correction effects.

I have seen the odd question bemoaning the inability of FCP X to keyframe color-corrections but as I have no interest in doing such things I have paid no attention.
However, I discovered in a Ken Stone article that color corrections can be keyframed using a free filter from Ripple Training.
The RT tutorial and a link to the filter can be found here:-
http://www.rippletraining.com/using-the-rt-color-balance-effect-in-final-cut-pro -x.html
Apologies if almost everyone else already knows this, but I am sure there will be somebody (like me) who doesn't.
The original Ken Stone article on all types of FCP X keyframing is here:-
http://www.kenstone.net/fcp_homepage/fcp_x_keyframing_effects_stone.html

One way to 'keyframe' colour correction with FCP X is to add the clip to the storyline, then move the playhead back to the beginning of that clip and use 'Q' in the Event Browser to add the same clip again as a connected clip, above the original.
Colour correct one of the clips, then keyframe the opacity of one of them to effect the change you want.

Color correcting certain parts of a video

Hello,
I am sorta new to Premiere, having come from Final Cut pro. I have a video that has spots that neec color correction. How do I correct those spots, without correcting the whole video?
Any help is appreciated.

I would suggest doing that in After Effects, not Premiere.
-Import your footage and create a new composition.
-Create an adjustment layer with your corrections (color corrector, curves, etc)
-Draw a mask around the region you want the color correction to actually show up. The rest will be unaffected by the correction.
You can create as many seperate adjustment layers as you want to correct each spot within your frame.
Then export the footage and bring it back into Premiere (or use dynamic linking if your machine can handle it).
If you don't want to use AE or don't have it -- you can follow a similar process in Premiere.
-Select the clip you want to add correction to and make a copy of it. Place it on the track above your original clip.
-Apply your color correction effects to the clip on the top track. Initially it will apply to the full frame and that's OK.
-Once you are done with making corrections apply a Garbage Matte to the top clip (four-point garbate matte, eight...sixteen...whatever).
-Adjust the matte to the shape of the area you want to correct.
(note: to edit the garbage matte points, you have to select the effect in the Video Effects panel)
You should be left with a color corrected region defined by the matte itself. Just repeat until you have all the different areas corrected.

How do you determine what shows are in free video on demand?

How do you determine what to include in the free on-demand shows? The Mentalist was always there before but is no longer. This is especially important for shows like the Mentalist and The Good Wife which come on Sunday nights after sports events. Even if I set my DVR to record 60 minutes over it doesn't always catch the entire episode. Would also like to see Person of Interest there. And last but not least, you should have a way for people to access netflix or other services from your service.

If you go to BROWSE then the FREE folder you will find that everything in there is free viewing. If you go elsewhere and try to watch a paid show, you will get a prompt asking you to purchase. It also shows the amount of the movie before purchase.

Need help: How to color correct professionally (with examples)

Post to video forum (before and after): Hi, I really need some help I want to color correct this video. I would love if someone had tips, either on:
-How you would correct the original
-What it looks like I'm doing wrong in my attempts (last 2 pictures)
Thanks!

I'd crunch it up a little more with a curves adjustment. These children don't look healthy and stronger contrast will help. Also push the reds toward a slightly more orange tone. They look too purple. There's also still an overall purple tinge which needs to be eliminated. See the included 3 minute quick shot of mine. Not perfect and requires more tweaking (too much yellow now, see the lips), but I think it better represents the feeling one would want to convey.

Color Correction in Final Cut Express HD

I'm editing a stage production of A Midsummer Nights Dream that was shot on two different cameras. The set is very bright and vivid, and i have read and re-read the FCE Help page on the color correction topic. I have corrected my master shots (wides). What i want to know is how i can adjust the colors of my close-ups:
1. the subject (Bottom in this case) is lit in a blue light (moon light).
2. the set (the woods) are lit by a bright green light.
What I want to do is match the colors to the master, but if i adjust to match the blue light on Bottom, the background loses its bright green. Likewise, if i try and make the green brighter to match the master shot, Bottom turns green too.
The help file mentions Limit Effect, but doesn't expand on it. Bear in mind i'm an 18 year old student, i pretty much need to be spoon-fed a solution!
Any help would be very very gratefully recieved, as i'm a bit pushed for time and trying to finish it this weekend (A-levels are looming...)
Thanks in advance,
James.

Limit effect is not going to help you in this case. You really need to control the overall image and get a balance between the wide and the CU. Color match Bottom's skin tone so it appears correct to you. Leave some of the blue cast to not lose the moonlight effect. Then color match the wide shot so that it has the same look as the corrected CU.

After Effects Color Correction Eye Dropper

I use the Color Correction Eye dropper for clothing videos and recently it stopped letting me select the dropper. I've tried restarting the program and computer. Would I need to re-install After Effects?

We are going to need a lot more information.
What exact point number version of AE are you using? 12.2.1? 11.0.4?
What effect are you using?
How are you using it?
Screenshots showing things like your comp window, timeline, and effects panel would all be helpful in demonstrating your issue.

Advice for logical workflow for color correcting and color grading

I am an experienced user of PPRO CS5. I am a novice with color correcting and color grading. I am also just barely competant in AE CS5. It has been suggested that I use AE for color correcting my footage. Can you advise me as to the most logical workflow for doing this in coordination with PPRO CS5? Are there some tutorials that you recommend? I subscribe to Lynda.com and I think that they have some great tutorials, I am unsure as to where to begin looking and what to search for.
Thanks so much,
Lisa

You can do it that way, sure. But you don't have to. You can accomplish quite a lot without leaving PPro. This has two major advantages. First, if you aren't using AE for anything else, it gets you out of using AE at all, so gets you out of climbing another set of learning curves.
Second, even if you are using AE for other things (I use AE to make motion lower thirds, for example), doing the work in PPro can improve exporting speeds. This is because AE gets restricted to a single processor core in some workflows as discussed in this thread and others (search around if you're interested). This can make exporting take 3x as long or longer, depending on how much footage has to be processed by AE.
So, how to do color correction without leaving PPro? Use either a luma corrector or luma curve effect to set black and white points, and contrast (use a waveform monitor to help). Then use a three way color corrector effect to get rid of any residual color casts (use the vectorscope to help, and the RGB parade, etc.).
If you find you have specific colors that need to be fixed, you can apply another three way color correction effect and use it to make that secondary color correction (for example I find the blue dyes used in many labels tend to fluoresce under fluorescent lighting, and has to be desaturated with a secondary color correction or it "blooms" on an HDTV -- IOW, it has to be made "broadcast safe").
If you want tutorials for using these tools, the ones on Creative Cow by Andrew Devis are quite good, and free. The ones on color correction with PPro cs6 start at tutorial number 47. There's a bunch of them. All good.
Finally, get a copy of Van Hurkman's Color Correction Handbook. May be the best technical book I've ever read, and it'll certainly point you in the right direction for doing color correction work regardless of which tools you use to do it.

Looking for a particular color correction tutorial

I am looking for an online tutorial on how to do color correction if the video one is working with has color bars. This happens on a lot of analog videotapes that come to me. I know what my scopes are suppposed to look like when analyzing color bars, but I need something that shows me how to get from A to B.
If I Google some varient of "color correction video color bars," all I get is information on calibrating monitors.
I am using Premiere CS5.5
Thanks in adavnce for any response!

Photoshop Color correction and Special color Effects

Can anybody pls tell me , how they create color corrections in movies like Harry Potter, Lord of the Rings. and all the other special color themes they create different images...
I use photoshop a lot but m a amateur to color correction thing .

There are many applications, that can do CC (Color Correction, often referred to as Color Grading, or sometimes just Grading). Premiere Pro has many CC Effects, and these should be done on calibrated NTSC, or PAL, monitors, and not on the computer's monitors. One reason for this is that Premiere is not a Color Managed environment.
Adobe After Effects also has many (actually quite a few more) CC Effects, and is often used for this purpose, even if one is not using it for its normal operation - compositing.
Along with those, there are many 3rd party CC plug-ins, like Red Giant's Colorista.
Once one gets past indie films, Hollywood would use workstations designed specifically for CC, with software not commonly available to the vast majority of the public. Again, the work will be done on constantly calibrated monitors, and by skilled technicians, who do nothing else, all day long. A good starting point would be the Black Magic Da Vinci system, but this really only gets one's foot in the door.
To get a handle on CC for Video, I recommend The Arit and Technique of Digital Color Correction, Hullfish.
Color Correction in Video is a subject, where popluar books will fill a large library.
Good luck,
Hunt

Exporting Movies Losing Color Correction

I have a movie created in iMovie 08 that I've used color correction on the clips. When I export the movie to an .m4v file or .mov file, the movie plays as expected with the color corrections applied.
However, If a most the .mov file to the web, or convert the .mov or .m4v file to an .flv file for playing in a Flash player, all of the color correction is lost and the video clips return to their originals, which is too dark.
Why am I losing the color correction?

I am using Flash CS3. Here are steps I am taking to import the video:
1. File > Import > Import Video
2. Selecting Videos (I've tried converting both .mov and .m4v files)
3. Selecting "Progressive download from a web server"
4. Choosing Flash 8 - High Quality (700kbps) profile
--- Under Video > Video codec the only two options I have are On2 VP6 or Sorenson Spark
Does this help? Please let me know if there's something more specific that would help answer the question. I'm technically competent, but new to video conversion.
Thanks for the help.
