Seeking Opacity/ Color Correction expert

Hi there,
I'll try to make this snappy. I'm layering a whole number of frames which each feature small twinkling lights on a black background. I have fiddled for some time to try to make them all appear together with the same level of brightness but alas I am stuck. Effectively what I wish to do is have the lights bleed through as if they were in the frame originally if you see what I mean, whilst the dark sky behind remains simply black. I suspect Opacity is not the feature to be dabbling with here. Are there any Color Correction buffs out there who could suggest anything? Something to brighten the light shades and neutralise all that black perhaps.
Hope that doesn't sound as much like jibberish as I suspect it does,
Many thanks in advance,
Jim, U.K.

Take a look at your Blend Effects. ( A fixed effect on every clip )
Its a bit trial and error but start with "Screen". (or "OVerlay")
Now a warning. My pet peeve about OPACITY it Premiere. !
To use Blend Effects..one also has to trial and error them with the level of opacity applied to each one.
As soon as you adjust the Opacity..it will set an Opacity Key Frame ( ie an opacity key frame dropping!)
Try and remember to turn off the Key Frame Stopwatch to work around this.
BTW - you might want to try and cluster all the lights in a sequence of their own then nest them back to the edit sequence. Still use the Blend FX in the FX sequence.

Color correction query

Hi There,
Following gaining a successful resolution to this issue using the 'Screen' mode of the Opacity function, I have now encountered a slightly different issue. Having layered multiple frames, I am experiencing an awful lot of what I think you might call 'noise'. The more I layer the frames of black, the more I lose the pure nice black colour of the night sky and it becomes lighter and more blurry and grey. Is there a color correction or other such function or technique that might eliminate that noise and maintain the clean black color?
Many thanks,
Jim, U.K.

Hi Jim,
Thanks for taking the time. I'll try to explain. So I took a continuous frame of some lights in the dark on the skyline that looked like this...
The frame moves around so they're in a different position on the screen, so I chopped it up and isolated those moments before layering a few frames and adding 'Screen' opacity to it. Effectively therefore the lights appear numerous times in the frame. Here's one of about 5 layers...
Effectively I wish to have these lights all fan out and fill the screen but as you can see the image is becoming grainier and grainier the more I layer and nest the frames. Here's what it looks like after 10...
Not pretty I'm sure you'll agree. I hope you can see what I'm trying to do though. I'm no expert but presumably there is some sort of technical term for the way that the multiple layers of black are obscuring the quality of the image. It's not your average difficulty I admit but if you know of any method by which the body of the image can be restored to that nice dark black whilst the lights remain clear and sharp then you would rescue me from an ongoing frenzied Googling session.
Kind regards,
Jim W., U.K.

Masked color correction - new Pr Pro CC features or still use After Effects?

I am finally getting around to this project. I know in CS6 the solution was to use After Effects. I think I kept putting it off as I was not as familiar with that program as I am with PrPro.
Anyway this is the issue. I have 2 hours of old video I have captured that due to an internal camera malfunction (that was not discovered until the end of the tape)
that has 5 or 6 cyan tinted narrow horizontal transparent bars running through it. The image is there under the bars, it is just viewed through this cyan
tint. The rest of the image outside of the bars is fine and the image inside the bars is fine, it just has a tint. This is old SD footage.
An AE expert said I can make an Adjustment Layer in AE and use the Mask Shape Tool to draw several boxes around the problem cyan areas, apply the Curves and Hue/Saturation effect to the adjustment layer, then color correct. Some feathering would be needed (I know PS too so I can handle that part ) I think I recall back with PrProCS6, I could do this adjustment but only one bar at a time. I could be wrong about that.
But anyway, sounds pretty easy in AE. But since I live in PrPro CC 2014 now, and I saw some recent new features with masks and adjustments, I was wondering if I could perform the same adjustments right in Pr Pro CC 2014? If I need to use AE CC 2014, no worries, I have that installed.
Thanks for the help as always! This is family footage that I would really like to rescue.

Monitor for color correction

Hello guys,
I am a newbie to Color and Color Correction. I have a dual monitor setup with my Mac Pro.
I have two 24 inches of DELL 2408WFP & DELL 2407WFP. These monitors have different color, and I think it is just stupid how Dell manufactures them.
Anyways, From what I have learned, I know I am not suppose to do perform color correction for videos on any regular LCD monitors. Can you experts suggest me good color correction monitor? Not too expensive. I am not doing any major flim/music video or anything such. This is just a hobby of mine, and I'd like to learn new things as time goes on. Most of my videos are travel videos & I try to make a cinematography out of it. I also shoot landscapes.
I hope you guys can direct me right.
Thanks,
Lowell

I think there is a lot of snobery on this forum regarding hardware requirements. If you are not entertaining clients who have just come from a Da Vinci suite, then you CAN live with out a Broadcast monitor that meets EBU specs. The important thing is to use a video monitor and not a computer monitor. You will need a decklink like card to get the video into composite or component format, that later will give a cleaner image but most television is viewed in composite any way. Colorgrading is a matter of comparing the before and after image and comparing the graded shot with the pictures around it. The scopes will keep you informed of the limits and will help you interprit the monitor. Rember if the shot looks better after grading on a cheaper monitor then it will look better on a Grade A monitor with SDI inputs. Don't let the "big" boys put you off, and use the software that you own to inprove your video and your skill-set.
Good luck from Boaz

No Color Correction to FCP from Color

I have project that I graded in Color, I rendered it and send it back to FCP, when I viewed to clips in the FCP timeline from Color, no color correction was applied to the clips, did I do something wrong?
How do I make work properly?
Any advice would be appreciated.
Thanks
Sigi

I am new to Color but had the same problem, I was rendering out to an external harddrive. Re-render or move your files to 'Documents Folder' > 'Color Documents' > 'Renders'.
Then re-send your color project to FCP.
I'm no expert but this might work.

Key frames effect controls and Fast color correction

I just learned about keyframes and gradual transistion of effects and i like that a lot.
Putting it in practice using the Fast color correction feature ; I seemed to miss the key navigation bar (I hoped to find it on the right side of the Fast Color corrector title line or ??? in the effects control panel)
I guess I'm looking at the wrong end of the world, or do keyframes not exist for fast color correction, I seem to notice the keyframe navigation for time Remapping and opacity..... where did I lose the keyframe navigation bar for fast color correction ???
Pro CSS3 on windows XP fully patched
hoping very hard I'm just looking at the wrong side of the world
please give me a hint.

You will find links to many
free tutorials in the PremiereProPedia that will quickly show you how things are done in Premiere Pro, including how keyframes work.

Selective Color Correction - Adding to multiple channels

Hi - I am using CS3 on a Mac OSX 10.5.6
I am experiencing an oddity when making color adjustments with Selective Color Correction. I am working with RGB images trying to adjust to get colors in gamut and to maintain detail before converting to CMYK. As an example, I have an image comprised of various red items. I want to add cyan to get some detail for the highly saturated areas. Regardless of the Relative or Absolute setting, when I add cyan I am also getting a lot of black added. By the time I get a 3% dot in cyan I may have 10-12% K. When I reduce the black it also reduces the cyan.
Is this because I am in RGB mode? I want to make these adjustments before separating to CMYK so I can keep detail that is getting blown away in the conversion. I would have hoped that because it is controlled with sliders for CMYK it would isolate it's effects to the specific channel but that is not what is happening.
Any ideas?

I am working with RGB images trying to adjust to get colors in gamut and to maintain detail before converting to CMYK.
If you are trying to bring totally oversaturated RGB colors into the CMYK gammut, then ideally you will have to learn about channel mixing. It may be necessary to reproduce the Cyan channel (Red) by finding detail from other channels. Selective color, as you've discovered can only take you so far.
Luminosity blended Hue/saturation adjustments taken to low opacity is another high end tip, and work around. If you cant deal with the complexity of masking and channel mixing

Add keyframes color-correcting a clip

I'm using Final Cut Pro 10.1.4 on an iMac with Yosemite 10.10.1.
When I try adding multiple sequential color corrections in a single clip, there is no way to add keyframes to each correction.
In the video inspector the add keyframe symbol does not appear.
In the show video animation window, if I clik "control k" the keyframe symbol does appear, but if I add more than 1 keyframe only the last one is active, so I can only correct the entire clip.
Is there any way to add more than 1 sequential correction using keyframes, instead of cutting che clip into multiple segment and correcting each one of them?

I have an RGB Channel Mixer that can be keyframed.
First, I recommend turning on Video Scopes (RGB Parade) and turning off the Color board for the title (you do not want to accidentally color grade the title).
RGB Channel Mixer is a title effect, so just drag it over the region you need to color "mix". You can use this effect in conjunction with the color board for the storyline clip. (Do not color correct the channel mixer!
You can toggle the view with the channel mixer selected — type 'v'.
You can download it here: RGB Channel Mixer
It won't hurt to try it and if you don't like it - just delete it. (It's still a bit of an experiment at this point.)
The effect works by mixing the red, green and blue channels separately against a black background solid. The Amount values use opacity to change the mix. The Boost values are different. They add a little "gain" in the channel. There's a subtle difference between the two. Contrast and Brightness controls are added to help with the lack of range assist (shadow, mids, highlights).

Color Correction Effect Controls Not Showing Controls

The recent upgrade seemed to work flawlessly until I tried to go back to some color correction I had started earlier. In some cases, when I click on the Video Effects tab in the Color Correction workspace, my controls are there and working. For others, when I click on the Video Effects tab, there's simply nothing there. I have dragged effects back onto the clip and then gone back to the Effects tab, and still see nothing. Has anyone else had this problem? Any thoughts?

I have the same problem. I've tried removing all effects, adding more effects etc, but in the Effect Controls window all I get is the name of the clip highlighted in blue. I've also gone to Window and selected Effect Controls, but all this does is reveal or hide the Effect Controls tab. The Motion, Opacity etc controls are not there when I click on the tab. Anyone have any ideas how to get the Effect Controls back?

Color correction in very long distance zoom-in

Hi,
I made a shot with the Canon XF305 that's basically a long distance zoom-in from one village to an other (around 1km distance clips-duration=1 minute).
The problem that occurs (because it was taken in the hills with a cloudy sky), that some parts where sunny and other parts with cloud shadow showing color errors.
I made a manual white balance (in the camera before) and the blacks and whites are ok, but I have some problems with mid-red and mid-blue is some parts of the zoom.
What is the best way to color correct something like this. I was thinking about using the scissors tool and separating some part of the clip and then making
some kind of transition between the parts of the clip.
So pro's how is this normally done?!
Thanks! David

Hi David,
That sounds like a good strategy and it is what I would do. It's often easier to correct each section, then use cross dissolves or opacity keyframes to blend sections together rather than keframing the color/brightness. This technique works really well with camera pans as well. Good luck!
Cheers,
Gerry

Color Correction Effect: "Change color to" change more that one color in the same clip(pp Cs4)

Hi all, I have watched and tried some tutorial to achieve this. My question though is how to change more than one color in the same clip. I'm asking because when I tried I had no problem to "color pick" one shade of my (Rock face) and turned it into a natural color picked from a good clip. But I was left with all the other shades to work on and if I repeated the procedure (pick the next destination color to replace) it cancelled my previous change so it seems that I can change only one color... I must be doing something wrong.

Wow! I did play a few other Youtube 3 color correction, but this one is so good and comprehensive. I did also like RGB curves tutorial. I don't know if all this is appropriate for my 1983 VHS clip nearly all green (I probably had the wrong white balance). What I achieved so far is not very good but I think much more watchable than all green! Than You again for this . I do also realise these guys are expert and still they have to use lot trials and errors and various techniques before getting what they want. I do appreciate their generosity to make some of their knowledge available to all of us.

Selective color correction "Lightroom"

I have two suggestions for Lightroom.
1.) Please absolutely for the next update an improved function for a selective color correction. Select with a pipette the color and over an input window the information selectively work on. That One should be able to determine sphere of influence still additionally. At present this is not yet satisfying. (see and compares, Photoshop PlugIN: aurelon "coco", or Software DxO Optics Pro v4.5).
2.) Information window that comparably as in Photoshop the values for RGB 0-255 indicates.

FCP Three-way color correction

has anyone using eather studio 1 or 2 and rendering out the timeline, if you use the three way color correction, the black levels of some clips will jump up about 5 percent too high?
if so, has anyone got the fix for this? i have been using the normal color correction because my 3-ways are pretty unpredictable after rendering.
it does this on my intel based quad core 2.66 and my powerbook G4 in both OS 10.4 and 10.5.
thanks,
joe

i usually expert using self-contained current settings and thats usualyl DV. the way i notice is two ways. the first, when i play the file back after export, some shots show a higher black level on an external monitor and waveform (the same ones used for editing). the second, when reimporting the file back into FCP, the waveforms show high blacks in the clip.
this is not on ALL exported clips, just the ones using the 3-way color filter. i did notice when using the older version of studio that, when adjusting the mids or whites sliders, the blacks would jump up and down in a seemingly random fashion. the more i adjusted the mids or whites, the more the jumping on the blacks. clearly a glitch of some sort. i havent seen this on the new studio 2.

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.

My HD TV as NTSC Monitor for secondary color correction

Can I use my new Panasonic HD TV model TH-42PX80U as a NTSC monitor for secondary color correction using both Final Cut Pro out of a Macbook Pro intel? What cable I can use to conect via HDMI? Will the color acuracy will be similar to that of a NTSC color correction monitor? will my TV do a decent job for NTSC? THANK YOU FOR YOUR HELP!
I am not sure I have this HDMI cable to be use in my macbook pro does it comes with it?

Can I use my new Panasonic HD TV model TH-42PX80U as a NTSC monitor for secondary color correction using both Final Cut Pro out of a Macbook Pro intel?
Yes, but I would only trust it if you are going to be making DVDs, and ONLY if you properly set it up. I would not rely on it for broadcast color correction. The reason broadcast monitors exist is to have a standard...HDTVs don't have a standard. Go to best buy and look at all of them....none of them match. BUT, as a nice simple solution for DVD, I'd use it.
But the only way you are going to get a signal to it is with the Matrox MXO. It will do component to the monitor, or you can get a DVI to HDMI adapter...if you do that the MXO software will allow you to set the monitor up to color bars. That option is only available from of the DVI out of the box.
Will the color acuracy will be similar to that of a NTSC color correction monitor?
No...it would be similar to color correcting NTSC on your home television...because that it what it is.
will my TV do a decent job for NTSC?
I doubt it. Taking an SD image and blowing it up huge on this HD TV...scaled up. I wouldn't think so. I wouldn't use it for SD color correction.
I am not sure I have this HDMI cable to be use in my macbook pro does it comes with it?
You have a DVI port on your MacBook Pro. And they make DVI to HDMI cable adapters I'm sure.
