“The Foundry” fixing the Rolling Shutter issue in some cases

We have already seen some Siggraph papers about fixing this issue in some cases (cf. horizontal distortion), but now we can see that The Foundry is working on it !!!

The Foundry is a great company known for their Nuke compositing software and also very known for their awesome “Keylight” plug-in as many others !

Check Out their blog and follow their research about all this stuff

Making Of : Philips Carousel

I think this is a really well done commercial. I wonder how they did it for a while (bullet time ? tracking ? green screen? ..) it seems they used a mechanical dolly controller which could reproduce the exact same path several time, and some stunt guy who were good at freezing body :). they shoot it one time with the stunt guys and another time without. Really cool !

MatchMove with Syntheyes a Nikon D90’s plate

Those days I’m working on Reels, at least one for the moment, a matchmove one. So far I’m putting together some pieces I did at my Fxphd’s classes, and also some of my shoot.

This one I did with my Nikon D90 which is none for a rolling shutter issue (jelly video look) when shooting video.

so those were the challenge for this plate :

  • shoot from the back of a car on small road
  • hand held
  • 24fps
  • 1280×720
  • 33mm

To be honest, the hardest part were dealing with the Rolling Shutter, this one is a real b**** ! it doesn’t show to much on the video, but when you look closer the image keep getting distort all the time which give a high error to the tracking data. Plus on top of that you have fast movements which give the “debug tracker” part a real nightmare. It’s not perfect, but I do think it’s looking very well.

you can watch the result in HD on the vimeo website


[MatchMove] : small road with Nikon D90 from François Tarlier on Vimeo.

Part of the shot I did track for my reel.
The particularity of this one, is the hand held kind of shot with the “Rolling shutter” issue of the D90.
It looks easy with all the features but it was a really informative one to track. I learned a lot with this shot, like do not try to get it perfect! at some point, I got a lower error (right now it’s 0.8hpix) about 0.4, but it wasn’t looking as good as this one. I guess it good be much better at some point but so far I think it works pretty well right now.
It has been track with Syntheyes, Blender for the 3d grid, and After FX for the compo/roto

This class (which was teach by Gareth Edwards)was really amazing, I highly recommend it !! I didn’t learn so much about AfterFX but mostly about how to get the job done in a small amount of time, and this goes through “organization” !! Keeping your workflow as clean as possible, taking time to renaming everything (cuz god it could get really messy in AE),…

My result is far from being perfect, I can see so many things I could change (the way they are running, the dust, the lighting, the shadows, … ). but so far, I think it’s quite good and I have so much other things to do that I cannot work any more on this piece! I’ll probably make a small “making of” video later on, just to show all the passes (shadows, AO, Dust, lighting,..) were done in After Effects, only the 3D tracking was done with Syntheyes, but so far it was a super easy one !

What I learned with this project :

  • Many AE tricks : can’t tell all of them, but I definitely think I’m more efficient now with AE. I’ve done many mistake and encounter many problems that did teach me a lot 🙂
  • Organization : I won’t say it enough, it might sounds silly but when you look at all the job that Gareth has done on “Heroes and Villains: Attila the Hun” (VFX breakdown here) in such a small amount of time, you have to say he had a pretty good workflow. So far that’s the reason I took this class and I don’t regret it
  • Faking : That’s mostly what I like in compositing, is that you can fake so many thing which usually with a good amout of blur you won’t see the trick 😉 . But even with that, we usually go for the hard way (3d, particle system, IA, ..). As I said, the result is far to be perfect, but I guess you have to keep in mind that the quality of your work could depends of the target you have and of course the budget (cf the production triangle). In this case the target is TV Shows, so I guess it should be “Fast” and probably “Cheap”, which leave “Good” a bit behind. Of course it should be as good as possible and that’s why I think knowing how far you can go with faking is a really good thing, and so far that’s also something I did understand more in this class.

FxPhd : Jan09 first 2 weeks bilan

fxphd Here we are, already the 3rd week! So now it’s done, for sure I’m taking the following 4 classes for this term:

  • MSV101 – Introduction to Massive
  • AFX301 – A Guerrilla Filmmakers Guide to After Effects
  • PFT202 – PFTrack in Production
  • FUS101 – Introduction to Fusion

MSV101

This class is really nice, but in the other hand, massive looks like the most complicated software I ever “had to” learn. But it’s really interesting and I can’t wait to see what is going to come out of it… Continue reading FxPhd : Jan09 first 2 weeks bilan

Libmv : making blender a tracking/matchmove software

libmv is a structure from motion library, which plans to one day take raw video footage or photographs, and produce full camera calibration information and dense 3D models.

The first targeted application for libmv is to integrate with Blender to make the first open source matchmoving solution

Roadmap – libmv – Release plans and goals for libmv. – Google Code.

I really looking forward for this project, since it will bring blender to a next level of vfx tool and make it the free complete opensource matchmove application available on “the market” 🙂

Check out the following video of what they got so far : Continue reading Libmv : making blender a tracking/matchmove software

FXPHD : AfterFX 303

Ah Ah I forgot, I already took this class and it’s just amazing !

To be honest I wasn’t going to take any AfterFx classes at FXPHD since I think website like VideoCopilot.net are way enought to get into it. But I took a look at the first class which is rule by Gareth Edwards and I was so impressed by his workflow he had.

Ok, just to be clear, this guy made the VFX of a show for the BBC, called “Attila – The Hun“, He did it :

  • all by himself,
  • at home,
  • 256 shots,
  • in 5 months,
  • using afterFX and Premiere

by working like that, YOU got to have great tips, really fluent workflow, and great organisation. So that’s why I enrolled in his class as well

The trailer of "Atilla - the Hun":

FreeTrack (a Track IR like Open Source)

“FreeTrack is a free optical motion tracking application for Microsoft Windows, released under the GNU General Public License. …

Head motions are tracked with six degrees of freedom (6DOF), specifically; yaw, pitch, roll, left/right, up/down and forward/back. …”

This is a really cool application that I use with Flight Simulator. It’s exactly like the commercial product Track-IR but it’s totally free and open source. All you have to do is build your cap the way you want. you have all the information on how to do it on the website, a great community to help you on the forum (and I think some people can build one for you if you ask 🙂 )

You really should take a look at it 😉
