1. Re: CS4 Pr : Colour pass on one area only
gapiro Jun 18, 2010 4:56 AM (in response to gapiro)I did think If i can cut out just an area on the guitar and run 2 layers would that work? If os , how would I go about cutting out the middle of the video?

2. Re: CS4 Pr : Colour pass on one area only
Bill Hunt Jun 18, 2010 3:20 PM (in response to gapiro)Welcome to the forum.
The idea of doing a dupe and then applying the Effect to the "upper" one should work. I'd add the 16-pt. Garbage Matte to that upper dupe footage.
Now, to really do a cool Key of just the guitar, take a look at this TUTORIAL on the RotoBrush in AfterEffects CS5. Back at the release of the CS5 suite programs, there was a better one, but now with hundreds of tutorials out there, I cannot find that old one.
Good luck,
Hunt

Bill Hunt Jun 18, 2010 7:49 PM (in response to Todd_Kopriva)Todd,
Thank you for that link. Going back to the very first days of the CS5 release, there was a great intro tutorial on the RotoBursh, but with all the new material, it seems to have become lost. I thought that I had bookmarked it, but cannot find that now.
If I do, I will share it, as the examples were excellent, and I think would be right up the "alley" for this OP.
Appreciated,
Hunt

If you describe it, I can probably point you to it. As one of the members of the team that created Roto Brush, I was keeping close watch on all such materials, so I would probably recognize it from a description. I even shepherded the creation of quite a few of the tutorials and such.

6. Re: CS4 Pr : Colour pass on one area only
gapiro Jun 19, 2010 1:27 AM (in response to Bill Hunt)Cheers for the help, however I only have CS4 Pr/AE, and not CS5
Is there any way I can cut out just a fragment of video in cs4 onto a second layer? even if its just a crude square around the guitar ?
Sorry i'm not that great at this, I really only use the software for adding semi fancy introductions and cutting tracks down to the right size etc, and making compilation videos! However We're thinking about making a proper video, instead of just videos of us performing so It would be nice to learn some efefcts

Ann Bens Jun 19, 2010 3:17 AM (in response to gapiro)Place your video 2 times on the timeline and add a white color matte to track 3.
Add the 8 or 16 point garbage matte to the white color matte and draw the guitar also add a Fast Blur (15) to soften the edges.
Add the Track Matte Effect to track 2 and point it to the color matte.
For finishing touch add the Black and White Effect to track 1 and also the RBG curves effect (set S-curve to the Master) to give it a more intenser look
Example shown below is for two garbage mattes.
If you want to change the whole color just add Tint.

gapiro Jun 19, 2010 3:39 AM (in response to Ann Bens)Thanks for that utterly awesome post.
It works very well, however naturally it is limited by the movement of the guitarist, presumerably this is where the roto tool comes in handy!
Very helpful and think i've learnt some stuff now
Many thanks.

9. Re: CS4 Pr : Colour pass on one area only
Bill Hunt Jun 19, 2010 9:14 AM (in response to Todd_Kopriva)The tutorial featured footage of a lady with slightly curly hair, and the RotoBrush was used to knock her out of the background. Wish that I could find where I bookmarked that danged tutorial. Just prior to the release of AE CS5, it was the first Google hit on RotoBrush, but there were very, very few other hits then. Now, there are 1000's, so RotoBrush must be quite popular.
Trying to recall the narrator, I think that he was a
bearded, dark-hairedgentleman with a buzz cut and no beard named Richard Harrington, and I got the impression that he might have been on the Adobe development team, rather than with some group like Lynda.com, or Total Training, but could well be wrong. Found it - Creative Cow Tutorial.Since I linked to that tutorial a few times, I have been pouring over the Premiere fora, looking for those links, but have not found any, and I know that I did at least 3.
Thanks,
Hunt

Todd_Kopriva Jun 19, 2010 9:48 AM (in response to Bill Hunt)Thanks, Bill.
I had seen that tutorial by Richard, and I don't like it. Richard shows a sub-optimal workflow: making lots of little strokes with a thin brush along the edge of the object (person in this case). The tool works best when you start with a broad brush and make broad strokes along the center of the object first. Tiny strokes along the edge come later if needed for refinement. I think that someone would be better served by the tutorials by Mark and John that I point to here.

Bill Hunt Jun 19, 2010 10:01 AM (in response to Todd_Kopriva)Todd,
Thanks for the critique. Never having used the RotoBrush left me without a baseline to judge. I was more impressed by the straightforward approach to a commonly encountered subject. Little did I know that the technique shown was sub-optimal.
Thanks,
Hunt

12. Re: CS4 Pr : Colour pass on one area only
Todd_Kopriva Jun 19, 2010 10:11 AM (in response to Bill Hunt)BTW, lest anyone think that I only criticize Richard, I'll point out that a lot of what he does is extremely good. I point to many of his books and tutorials from After Effects Help. He just didn't quite nail it on Roto Brush the way that Mark Christiansen did in his video.

Bill Hunt Jun 19, 2010 12:22 PM (in response to Todd_Kopriva)Todd,
I just took a look at more of Mark Christenson's RotoBrush tutorials, and like what I saw.
Thanks,
Hunt
PS - I should have been spending my time looking at everything he had, rather than trying to find that Creative Cow tutorial... Now, I just need to update my suite to CS5!!!!!

can anybody access the jpg images below ? I get an error on every link saying the link is bad.
Thanks for any info.

I cannot. IIRC, when Ann posted, the screen-caps appeared in the body-text of her reply, but now seem to be dead, at least on my Google Chrome.
Not sure what happened,

David Zeno Jun 25, 2010 12:32 PM (in response to Bill Hunt)Hi Bill,
thanks for checking into that for me.
by the way, even without Ann's images, I was finally able to use her technique, and wowie, it worked GREAT !
( in regards to my other post , where somebody linked me to this thread )
Dave.

17. Re: CS4 Pr : Colour pass on one area only
Bill Hunt Jun 25, 2010 12:58 PM (in response to David Zeno)Yes, I caught that in the thread, where you replied to Todd. Glad that it worked fine. Ann's methods are almost always spot-on.
Good luck, and wonder what happened to her images. I have seen similar, where they no longer displayed in the reply, but some clicking/dbl-clicking normally opened 'em up. Could not get those to open?
