Spurious colours from RGB Curves and Track Matte...

Hello people of the forums.
I am working on a music video.
In a couple of places in the sequence where there are two or more visible layers overlapping with top layer/s having less than 100% opacity there is some unwanted 'extra' colours appearing which can be seen in the attached image below.
In the left image the unwanted colour appears in the center above the mans head, it is grey coloured.
In the right image the unwanted colour is the red.
All blending modes are Normal. There are Track Mattes in use. There are RGB curves being used.
As a result of trying to gather pertinent information for this post I found a cure, hahaha.
For the left images situation I found that turning the RGB curves off removed the colours, so I replaced the curves with Levels and the issue went away...
So for the right images situation I added a levels below the track matte and above the RGB curves, and the issue went away, no adjustment to the levels at all... I moved the levels from between the Track Matte and the Curves and the issue reapeared.
I will post this anyway but not as a question.
All the best
Peter

Hi Bill,
This is so weried I know how to do this where to point ect ect.
If i move the clip with the track matte on I get a crash.
I made a new seq and used same clip and it works. so I made a second clip next to it and it worked. I copyed those clips back to the old seq and it did not work...
It's been going on for a long time.. what do you know about seq setting with track mattes? do they only work well on some and porly on others.. all Ideas to find a answer.
answer to your above quest yes I am doing it right and why should I get a crash if I move the clip with the track matte on.
I think if we can answer that we will have fixed it.
over to you Bill
thanks for hanging in there.
Best

Continuous rasterization with contained comps, 3D layers and track mattes

I have an project comprised only of AI objects contained in comps, used with 3D and I have a problem similar to many I have seen on this forum, though I have tried every solution supplied to no avail.
At the lowest level comp are some AI layers that are animated in the comp. Call it comp A.
Two copies of comp A are in comp B, each track matted by another AI layer.
Five copies of comp B are in comp C.
Comp C is placed several times into 3D space in the main comp where a camera moves past.
All the vector layers are 3D and set to CR
All the comp layers are 3D and NOT set to CT
Without the proper settings for CR/CT, the track mattes slip all over the place (but things rasterize well).
WITH the above settings, nothing rasterizes properly (but the mattes work). The comps appear rendered at the original size of comp A, which is heavily pixelated (or blurred with quality turned up) as the camera moves past.
I have tried precomposing the track-mattes and their objects contained in comp B into their own comp (also following above settings) and got no change.
Of course, in retrospect, I could have scaled up the objects in comps A, B and C but at this point the project is in final stages and I'm wary of all the adjustments it would take to go this route (it also seems like a very wrong way to go about working with vector graphics).
Can anyone help, or is this just the way AE is? (I am fairly experienced, but < 1 year.)
Thank you for this forum.

Here's what you are probably missing. Let's set up something very simple. You have a Main Comp and a PreComp. The Main comp contains the PreComp and a Camera. The PreComp only contains single layer - TestShape that is a 20 X 20 pixel red solid and it has a circular mask applied so it looks like a dot. When you add a mask to a solid you have essentially turned that layer into a vector layer.
Let's go through a couple of things in the PreComp. Fist, scale TestShape 600% and look at the edges. They are a mess. Turn on Continuously Rasterize and they are perfect.
Look at the Main comp and scale up the PreComp layer 600% and the edges look terrible. Turn on Collapse Transformations and the edge is sharp.
Notice that I used two different terms here for the same button. Collapse Transformations only applies to layers that are compositions. It means that the items inside that composition are treated as if they were in the main comp. In other words when Collapse Transformations is applied we are scaling the TestShape layer 600% and then scaling that again 600% effectively making the layer 3600% bigger. Did you follow that? It's important.
Now let's go back to the PreComp and add a second 20 X 20 blue solid with a circular mask. Call the Blue Solid TestShape 2 and make it 3D and turn on CR. Add a camera to the comp. Now adjust the z value of the TestShape 2 layer so that the layer is about the same size as the 2D TestLayer. If the TestShape layer is scaled to 600% then the Z position of TestLayer 2 will be about 80% of the Zoom value of the camera. Now move the camera's X position just a little to the right so you have a Blue circle overlapping a Red circle in your comp. Turn CR on and off for the TestShape 2 layer to see how that works. Moving the TestShape 2 layer closer to the camera is exactly like scaling the layer.
Now return to your Main Comp. With CT turned on you should see only the blue circle. This is because CT is ignoring the camera in the nested comp and using only the Active Camera in the MainComp. Turn off CT and you'll see what you see in the Pre-comp but the edges will be soft. The only way to get the same view in both comps is to copy the camera in the PreComp and paste it in the Nested Comp.
Here's one more interesting thing that happens. If you make the PreComp a 3D layer it will multiply the position value of any 3D layers in the PreComp making camera moves an interesting but not impossible thing to deal with. In this example if you were to make the PreComp 3D it would look like the blue layer disappeared, but just move the camera back and it will show up again.
Now let's add a track matte by creating a new rectangular solid that is 1000 pixels wide and 200 pixels tall and add an elliptical mask. Scale this up 600% use it as a track matte and turn on and off CR. The results should be predictable. If you make a track matte layer 3D moving the Z position around will not effect what is matted out in the nested comp. If you had 2 3D layers in the nested comp you could not move the track matte between the two 3D layers and only mask one of them.
I hope this helps. It's a good exercise to help you understand how CT and CR work. Start throwing in effects and you'll learn more.

- - - Identifying Pantone TPX Colours from RGB/CMYK Photoshop/Illustrator files - - -

Hi there.
I am currently working on CMYK / RGB designs in Photoshop/illustrator. I need to supply my printers with Pantone TPX colours. I have the Pantone TPX colour book in front of me and i am picking the most appropriate colours by sight ( which is basically guess work ) . Is there a way where i can use the eye dropper tool to pick a colour and identify an exact Pantone TPX match (or the closest thing)
Apologies in advance if this seems like a trivial question, any help/insight would be greatly appreciated!

Hi ColorWerx thanks for your reply.
Sounds interesting, although i don't think thats quite what i was looking for though ( something official from PANTONE maybe)
Is there a way i can access your utility?
Can you give me an example - RGB colour i'm trying to match:
R:0
G:255
B:255

Encoding fails with RGB Curves after update.

I'm trying to finish a project, but Premiere is gving me troubles..
I'm uisng Creative Cloud and I saw that there was a update for Premiere and i thought: "Why not, it can't hurt..", but boy was I wrong!
Before the update I could play and export my sequence without any problems (except laggy Playback), but after the update Premier wouldn't play the sequences (only audio) and when I tried to render previews I got an generic error.
After some investigation I found that there could be a problem with RGB Curves, and sure enough, after disabling the RGB Curve-effects on the Clips it worked fine!
I also found that it should work fine with GPU acceleration enabled, so I activated it. Now my project played fine in PP (with RGB Curves), and thanks to the GPU it didn't laily
Happily I started the export and went for a walk, but when I got back the exports had stopped and there was an generic error!
So, apparentely the exporter(/media encoder) doesn't use the GPU (*sadface*) and so is affected by this weird bug.
What should I do now??
I use RGB Curve for color correction and grading through the whole sequence, so I guess I need to find another effect that gives me the same result..
Windows 8 64bit

I generally try to be careful with updates, and I should have known better (especially than update in the middle of a project). But given it was a minor update and that minor updates is supposed to fix bugs (and not introduce new features/bugs..) I thought it would be safe.. But it's a weird bug (that couldn't have been fixed by replacing the RGB Curve effect file with an older version!?) and even weirder is that the text I read was for CS5.5..
Luckily I had also installed PP on my laptop, so I just copied the program files from the laptop to my workstation and I could carry on and finnish the project.
The thing about waiting with updates of this kind is that you don't get the bug fixes. It's one thing to wait before you jump on the next big update (like CS5.5 to CS6 etc) and another to install "bug fix updates".
There is no real "infancy period" for minor updates, they do not mature, there is one update, if that update introduces a bug, then that's fixed by the next update etc etc.
In the end, you don't gain that much by waiting to do minor updates (albeit you should avoid it during a project), since minor updates should fix the bugs that your software currently has and you could, theoritically, just end up with more problems when you do decide to do that update.
One solution could be to never update, but then you're stuck with the original bugs..
The best thing to do is to do a backup before updating (and I should've done that..).
What would've happened if I decided to install Premiere Pro a week later?? Then I probably would've gotten the latest version with the update and so the bug!?

MBP keyboard and track pad not working

Today the keyboard and track pad on our mac book pro laptop just stopped working. The mouse connected to it by usb continued to work but we can't type or anything. We tried the ^F6 keyboard shortcut but it did nothing since of course the keyboard isnt working. And it is also not the number lock key. The computer was working fine all day up until now. It is just under a year old. Any ideas?

I'm having the same problem. It appeared yesterday and then magically "repaired" itself. My MBP was fine today. Tonight the problem is back. No response from the keyboard and track pad. Track pad works fine using a USB mouse. My problem appears at start up. The cursor is in the usual upper left hand corner. It can't be moved. Restart, sleep then restart do not solve the problem.
Suggestions?

Is there a way to change the color of the Bezier Curves and points to a different color other than black I find it perplexing while setting points and curves working on a photo that needs to be separated from it's background for placement on transparent

Is there a way to change the color of the Bezier Curves and points to a different color other than black I find it perplexing while setting points and curves working on a photo that needs to be separated from it's background for placement on transparent backgrounds. Any thoughts?

Yes. Well, sort of: instead of a "path", set the pen tool to "shape" in the tool properties. Then set the fill colour to transparent, and the stroke colour to the colour you want. You can also set the stroke width.
Not perfect, but at least you can see the path more clearly - the anchor points and handles still remain the default colour. Open the path panel, and right-mouse click the path shape to create a selection based on that shape. The Paths panel menu also allows you to create work paths based on that shape.
Unfortunately when you try to move the handles the black thin outline appears again until you release the mouse button.
This is one of several things that works better in Photoline: in Photoline, once the path is set to a specific colour, editing the path uses the actual colour and stroke width. which is extremely handy for creating path based selection with awkward background colours and/or a high resolution screen. In Photoline the handles and bezier points are also much, much larger, which makes it rather simpler to work with as well - especially on a higher resolution screen. And when selected the handles and points are a clear red with a black outline - again easier to spot and identify. I just works better, in my opinion.

CS2 Eye dropper and clone tool not picking up correct colour from image.

Hello everyone, Can anyone help me please. I have an iMac with 0SX 10.4.4.
Plenty of Ram and hard drive space. In using CS2 the eyedropper and clone tools will not pick up the exact same colour from the image that I require. It is always lighter in shade and has on occasion been white. Any help in solving this problem will be much appreciated.
Yours in anticipation, Geoff Walter.

>The eyedropper is picking-up the color as rendered in RGB on your Monitor...
Really? Not from the pixels in the file? So the same pixels are reported with different values depending on monitor setup? This is about how the eyedropper reports pixel values, not about how they are rendered to the screen, is that correct?
Just to be sure here, this is so even with the eyedropper set to point sample?
Al
Edit: Or do you mean that this is a known problem with 0SX 10.4.4. and Photoshop, in which the values are picked up from the monitor and not from the file data?

AE CS6 Track Mattes and Continuous Rasterising not working

Hello,
I'm having an issue with After Effects CS6. I'm using some Illustrator files in a comp. Within this comp I have used Track Mattes to mask off certain objects. When I put the comp into my master comp and turn on Continuous Rasterisation
the track mattes seem to slip out of place. None of the layers within the comp or the master comp are 3D layers so this isn't the issue. The Track Mattes are Illustrator files as are the objects being matted.
This is the result in the master comp.
These are the layers in the Master comp.
And these are the layers within the comp.
Thanks for your help

It works as designed. Enabling CR changes the order in which items are evaluated (there's some blurb on that in the online help somewhere and a link to a more detailed article from the Meyer books), including mattes and masks plus your parenting will influence transform positions as well. You will have to forego CR or restructure your project.

Convert image from RGB to CMYK and back to RGB

Hey.
I wonder if anyone has experience with converting image from RGB to CMYK and back to RGB?
I had a TIF in RGB then converted to CMYK but I figured that it might be better to keep in RGB, so I converted back. I read that it supposed to cause some loss in the data, but I can't see anything on the image, it is still very huge and the 2 RGB files has the same size as well. Is there a way to compare the resolution of 2 images somehow, or how can I see what I lost through the 2 conversions?
Thanks for help

I had a TIF in RGB then converted to CMYK but I figured that it might be better to keep in RGB, so I converted back.
The original RGB data is not being restored by converting from the CMYK version, so the term "keep" seems inappropriate.
What are the actual Color Spaces (ICC profiles) involved?
Is there a way to compare the resolution of 2 images somehow, or how can I see what I lost through the 2 conversions?
How did resolution come into this?
To determine how large a portion of the image has been changed you could
• make a flattened copy of the original image
• place a flattened copy of the RGB->CMYK->RGB image on top of that and set it to Blend Mode Difference
• add an Adjustment Layer (Curves for example) to brighten the image

I have over 1200 songs in my iTunes library that have always synced fine, I have added a new album to my list from one of my CD's, synced to add it to my library but less that 100 songs are now on my device and no matter how many ways I try its not worked

Does anyone know why this is happening and how to rectify the situation as I have tried every help setting for the last 4 hours.

I have tried everything I have read on the Internet about sync issues and restore etc and not there isn't a single song on my iPad or iPod touch. All of the songs are listed in my iTunes but are all greyed out, some have the cloud symbol next to them but lots don't and some say waiting.
Long and short is nothing will save to my devices at all.....HELP !!!!!!!?

Tried to upgrade to osx 10.9 from 10.7 and I didn't notice that it downloads in the launcher. I turned my mac off and ever since then it has glitched out and will not download no matter what I do. I have had it for 3 years which is out of warranty.

I have had it for 3 years which is out of warranty. It now has a blank bar under the launch pad and no matter how many times I try re-downloading it or restarting my computer it does not work. I use too play starcraft and other games on this computer although new patched/updates have made it that I can no longer do that now. Really frustrating having to deal with this especially after buying this computer upfront and now out of warranty.

Go to your Applications folder and find a file called "Install OS X Mavericks". Send it to the trash and delete it. Then try the download again.

I have an Imac in my bedroom and apple tv hooked to my big screen in my living room. When I select mirror Imac on the Imac to view on the big screen in living room, can I get a wireless keyboard and track pad to control Imac from living room?

I do something like that, and can confirm 20 feet won't be a problem. More than 30 or so might be.

Black and white PDFs printing in changing colours from preview

I am often printing black and white PDFs from preview with my HP PSC 1510 All in one printer and scanner. After updating to OS 10.6, my PDFs have been coming out in colour. They usually start in black, then change in the middle of a line of music or text to purple, red, blue and green. The longer the document, the more different colours I get. This is not occuring when printing black and white documents from NeoOffice, only when printing black and white PDFs from Preview. As this is what most of my printing consists of, this is extremely annoying.
I am high on black ink, as I recently changed catridge and I have also made certain that the printer driver knows this by using the printers and faxes preferance panel and selcting the" levels of material" button to update this, and it seems to understand that I am high on black and low on colour, but still the problem occurs with every PDF i print. (If this button is called something else, but similar, that is because I am using a norwegian system and don't actully know what it is called in the english OSX.)
There is no "print in black and white" button in the printer dialog either, so I can't fool the printer to print in black and white what it perceives as colour in my black and white PDFs either.

Be sure you have applied both the 10.6.2 update and the absolute latest drivers for HP from Apple:
