there's always this:
make sure you read all the way through. there is a lot. with good practice you will be able to know how to use it for what it can do, and when to stop and try something else.
would also recommend these courses:
also read this:
it's 5 years old but still very good.
...I was also wondering whether someone could tell me whether there was a better, or at least cleaner...
Sure -- chroma key. You light it right, you use a good camera, you're almost done after a couple of clicks.
Thanks for the reply again!
Thank you very much for your reply!
Rotobrush works very well on some shots, I end up doing a lot of roto by hand because it's faster on many of the shots I work on, Mocha AE is also very good at Roto. It all depends on your shot. Yooofi is more than correct when he recommends studying up on Rotobrush because it is not intuitive at all.
A very quick look at manual rotoscope:
Hi Yoofi! Sorry to bother you again, but I was just wondering whether there was any real difference between the two courses? And I (hope this doesn't make me sound lazy) was wondering whether there was anything a bit lighter then those courses to start me off?
James no worries! this is a pleasure. when you ask question I can learn myself what works and what doesn't. I get to view the help files again. see things I thought I knew, get comments from my peers of better suggestions. this is a learning experience for all involved and I am thankful for it.
if I had to pick one specifically for VFX I would choose Mark Christiansen (all praise to Chris Meyer my personal favorite Ae Guru) meaning I would pick this course: After Effects Compositing 05: Rotoscoping & Edges | Lynda.com and it is not for beginners (both courses are stated as Intermediate level) the reason is that it is the most comprehensive I have found. I would watch both, and I did.
Roto work takes a lot of practice. I am saying Roto Work and not RotoBrush because not everything is suitable for RotoBrush. and it takes practice and skill to know when to choose another method or COMBINE methods (pro's work this way). takes a lot of practice. this tool is revolutionary. I expect us to see this process of matte extraction get more and more automated especially in the clean fine edge department. Rotobrush is MAGIC .
just recently I made a tutorial: Rotoscoping Techniques - Photoshop & After Effects on Vimeo of using Photoshop to Rotoscope Stop-Motion animation to get frame by frame precision thus combining the state of the art Brushes of Photoshop, with a timeline that's available, and roundtrip back to Ae for composite my work. but this is a very esoteric example for a very specific use. just free publicity here - that's not your case.
with all that said, perhaps if we could see a screenshot of what you are dealing with, I could give you more education suggestions. there are many factors that could impact on your edges so instead of naming everyone - show us a frame or better yet, the video you want to Rotoscope using Rotobrush.
Thank you very much for making me feel better about asking so many questions haha. I'll go ahead and watch the course you recommended as I think I didn't quite get how complicated rotoscoping is. I think I need to start putting more effort into perfecting it. I like making funny videos about trending topics. Mostly I will take a picture of a person involved in something trending, cut there head out and put it on a movie clip or music video to give the whole thing a different meaning if you know what I mean. For example:
I want to put a different head on top of Leonardo DeCaprio's head in this clip (The wolf of wall street - I'm not leaving scene (humming) - YouTube ). However, the mic covers his face at certain points so I want to mask it out.
In this clip, I want to put a different head on top of the guy who is shouting "no" (Austin Powers International Man Of Mystery Steamroller - YouTube ). But again, his face is obscured when he puts his hand up.
I've tried rotoscoping (with the rotobrush) but it's never perfect. You see the outlines from the background around the fingers and I do try and take time rotoscoping it but it's never as perfect as I want it to be . I am a bit of a beginner with AE, and I only discovered refine edge (NOOB!) a couple of weeks ago so I haven't really used it that much. I don't know whether that would help much or whether I need to put some effort into really learning how to rotoscope properly to get the results I want.
If you want roto work to be successful you must shoot with roto in mind. That also applies to all compositing work. Just shooting a shot without careful consideration of all the post production requirements can add hours or days to the process the shot. Many poorly photographed scenes cannot be successfully turned into a convincing composite you would want to put your name on.
Really complex roto work may require many duplicat of the shot. You should assume one tool is all that will be required to do the job.
Rick, he is not going to shoot any footage. he want's to composite from different source footage that were not intended for roto. this is an art form of itself. more about artist who do this type of work is here:
James, study and perfect your technique until you get it right. since you are planing to do this type of spoof videos, it's not the same critique eye as game of thrones. so be gentle with yourself, but try to do your best and keep getting better.
Rotoscoping is one sub-field of Composition and it's with the potential to be the most Complex. you will need to have all three main fields of Compositing nailed down to be able to produce satisfactory result of A over B. unlike Motion Graphics, here precision is paramount. one nudge to the wrong direction, or edge appearing, can ruin the whole shot.
my favorite way of the describing Compositing (took it from Mark Christiansen) and this is how I teach my students is into 3 main topics: Selection, Tracking, and Color Matching. Selection Comes first but also in conjunction with Tracking. for instance you could Stabilize a shot, Roto it, then re-introduce the motion (Rick shows this in his tutorial here in the thread). so all of Compositing requires study an patience and a lot of practice. every Shots present a challenge and using the right set of technical choices gives you the ability to get the job done and in a timely fashion - that's why it's called Art by many. it's not just click here and there. you need to prioritize and know when to move on, when to stay on it. on this aspect RotoBrush can be a pain. you could find yourself investing a lot of time on a shot that could be solved with different combination of tools.
Thanks Yoofi! By the way, loved the "Chickening", that's pretty much exactly how I want my spoof videos to look (mainly the heads on top of the original actors). I take it it would be a good idea to learn over techniques of rotoscoping instead of relying on the rotobrush? I think then the original courses you suggested would be a good idea to study!
it will be the perfect place. you can even get first week for free I think. the price is fair too. GOOD LUCK!
Thank you very much Yoofi for all your help! I'm sure I'll be asking more questions in the future
