Update from milestone 2

I had to update some small things from Milestone 2 (last week) and I forgot to actually post it here! but here are some more tests of the project! :)

some fast paintovers I did, for the first scene:

paintover_scene1_2 paintover_scene1_3 paintover_scene1_4 paintover_scene1

for the last scene:

paintover_scene2_1 paintover_scene2_2

the second one is just a “darker version” with smoke/destroyed landscape further away insetad of the the more “beautiful” version. I kinda like the concept of the destroyed area but I still like the first version/ the “beautiful” version best.

I also got some real nice pictures from teodor Hjelmqvist of landscapes:


I did find pictures of mountains/llandscapes on www.cgtextures.com as well but those pictures is rarely over 2000 px. so I really hope that i will be able to use the pictures I got from Teodor :)

I also tested to add my own camera in the last shot, and to animate the butterfly + make a fast mockup of the last scene:

the tracking is still off after importing it to maya. it could be the scale that changes but I’ve tried to import it with different scales from Nuke. I still get the same problem. the locators get the wrong position in maya. the track still looks stable in maya but somehow off. It could be the camera settings from nuke or from the moment we filmed that isn’t correct, So I will test to do a new cameratracker in Nuke but without adding a “known” camera. if this doesn’t work I really don’t know how to solve this problem. any ideas?

Milestone 2

Time for milestone 2! it was a little bit caotic but in the end I got at least something to show :)

so, what I have been doing so far is:

– some smaller tests of the tracking and keying

– exported all the dng material to playable formats for Nuke and Premiere pro. I rendered everything from After effects as lossless avi movies. Then I imported everything to premiere pro to be able to play around with the clips some more and to see which ones I were gonna use.

Here are two film tests I did in premiere pro. I really liked these shots the most and I think the first film test is the best one even though I like the clips in the second film test as well. especially the last scene when the camera starts from her back. But I still think the first film test is better: I get to see more of her eyes and I really like that she nods a little in the end of the clip. in the other scenes that I got (the same view) she doesn’t look up that much or stops moving her head in the last 2-3 seconds. so this one really is the best.

Film test one:

film test two:

as I said before I also did some small tests for tracking and keying. The keying for the first shot might turn out to need some work. especially around her feet. the shadows and the shoes is both “black-green-isch” so the keyers don’t really know which colors to pick. I might need to rotoscope that a little. one other thing I also saw, and kinda knew from the beginning that I might have some problems with, is the reflections. Both her hair, her skin, the book and the shoes got A LOT of green “lighting” and reflections. I tested to remove it with just a hue correct but I think I will need to script a little for the despill in Nuke to make it look better. Hue correct turns the green to purple-isch colors = not that good looking.
One other thing that I’m also having a little bit of problems with is the highlight of the greenscreen (the one I mentioned some days ago, the one between the floor and the wall). Let’s just say that I’m happy she’s just sitting down, not moving so much. that way I can create good looking roto’s for her if it’s needed. not much motionblur = good!.

The second shot turns out to be a little bit easier to key out. The only thing I have to worry about there is the despill (again) and her hair against the highlight of the greenscreen. but the IBKGizmo in Nuke really do look good in this shot, especially togheter with keylights and some garbage mattes :) it still need more work but from the first test I did I realized that this shot might be more friendly that “scene one”.

Petals Update for milestone 2:

I also had time to make some tracking tests in Nuke. I will test this in matchmover as well to see if I will get a better result but the result that I got in Nuke looks really good! The only thing I might need to do for the first scene in to stabilize the shot before tracking it. just to get rid of some small “shaky” effects. AND I also have to check the size of the scene in maya vs Nuke. The tracking looks good in nuke but different in Maya. it’s still stable in maya but the locators/trackingpoints gets a different locations. I probably need to check the settings before exporting it to maya, and check the settings for Maya as well :) Maya’s scene got everything in m while nuke has everything in cm. that could be the problem, which also is easy to fix :) I can either change the global size in nuke, or in maya. I think I can choose to export the tracking from nuke in meters as well.

I didn’t have time to track the second scene but I think I will start by fixing the first scene, then the tracking for the second. I will also need to add my own camera for the second shot, because, right now it would only reach to the tree branches.

tracking in Nuke:

(as you can see the tracking looks stable in Nuke, but is off when I rendered it from maya, look at the “petals update for milestone 2”)

So, this week my goal is to have a nice looking key and tracking for both shots. I really want to have some 3D objects for the scene done as well. like: the temple and the torigate. But that all depends on the tracking and keying.


over and out!

filming done!

This week has been a little bit caotic with both broken camera discs and some minor accidents like slipping while carrying a bench to a car and back a car into a tree, but in the end I got the filmed material!

It all started this Monday when I finally got to speak with Mattias (the camera man) about my storyboard, when we would be able to film, how we where going to do this et cetera. I showed him two different storyboards. The first one with the bench and the book and the second storyboard without the bench and book. After some small talk and new ideas we decided to stick with the first storyboard, the one I uploaded here on my blog a while ago. We choose this because it would look better and more realistic, but also because we would be able experiment more with that storyboard while filming.

Afterwards I had to find an actor for my shot. I only asked one person and she said yes! a friend of mine called Kajsa Holmberg.

I also got a lot of help getting everything I needed. for example: trackingpoints, booking the “green screen room”, lamps for the shot, cameras, a crane for the camera et cetera. Both Arash Vahdat and Mattias helped me a lot with this. I couldn’t have done it without them!

So, on wednesday we started to prepare the room where we were gonna film. Kajsa and I ran around setting out tracking points on both the floor and the walls, placing the bench, cleaning up the room and putting filter on the lamps. We also took some measurements of the points (mostly the origo that we put out in the scene) and the bench. I must say that we used A LOT of trackingpoints. I will probably use half of it while tracking the filmed material, but I thought that it wouldn’t hurt to be extra sure. I got a lot of trackingpoints from Arash so why not use at least half of them?


While we were doing this Mattias started to work on the camera, setting up more lamps and the crane and rigg for the camera. And just when we where going to start filming, we realized that the disc for the camera was broken. Mattias took the car and went to his office, hoping that he had an extra disc, but he didn’t. So we decided to film on thursday instead. I can say that I didn’t add this one to my “risk analysis”.


On Thursday everything went well. Arash helped us to get a new disc for the camera and then we could, at last, start filming!

We filmed everything with a Black magic cinematic camera, in 2.5K. While testing the camera settings we decided to film with higher exposure, just to be able to reduce the noise that can occure. I will be able to change the exposure later on, I also tested this while we were filming. One thing I didn’t know about this camera is that the result came out in dng format. I thought Adobe premiere pro would be able to import the sequences, but instead it was Adobe After effects.

After this everything went smoothly. While filming we tested different angles, different hights and movements for the camera. While doing this we also imported it to my laptop just to check if the movements of the different shots could me matched with each other. I had two main shots in my storyboard. but as the filming was pretty straight forward we decided to take some extra shots of Kajsa that I might be able to experiment with later on.

The only problem we had that we couldn’t entirely fix while filming was the lighting of the greenscreen. We tried to put up more lamps and lowering the ones from the ceiling but we still got a little difference on the greenscreen. Especially the part that connects the floor and the wall. No matter what we did it got brighter than the rest of the greenscreen. I don’t think this will be a major problem while keying but we did our best to smooth it out just in case.

ready, steady, go!

Hi there! My name is Michaela Sjöström and I will be working on a project called “Petals – a CG environment”. The reason to why I choose this project is because I want to get a better understanding in how to make a photo realistic outdoor environment with both organic and static objects. by doing this I can focus on one of the things I like the most: texturing and lighting, and how these two components affect each other.

How will I know that the environment is photo realistic? that’s one of the first questions I got during the proposal stage of this project. I will use filmed green screen material together with my environment to make it look better and more alive. I’m also gonna have objects that will integrate with the actor to make the shot even more realistic. The object I choose to integrate with the actor is a butterfly. The reason to this is because it will improve the connection between the filmed material and CG.

One other thing that I want to get a better understanding in is the workflow. what should I begin with? what can I cheat with? (example: do I really need to make everything in the environemtn in 3D), et cetera.

It took me some time in the making of this idea. I think I have 3 different storyboards and moodboards at the moment but the one I finally ended up with is this one:





The reason to why I choose the japanese environment during the cherry blossom is because I find it beautiful, colorful and it will be interesting to work with all the components that this environment can give me.


A woman is sitting on a bench in a japanese park, reading a book. a butterfly flies towards her and lands on her book. she looks up at the butterfly, and just a second later it will fly away again towards the sky. the view will follow the butterfly as it flies up over the cherry trees and away into the distance.

The result:

I want the result of my project to be a short vfx shot, around 10 to 15 seconds, in 1080p. the shot will take place in Japan during the cherry blossom, under daytime.


If you want to read more about the planning and research of this project, please look under “milestones”. In MS1 you can find every document I have been working on so far.
