WEEK 1
1.1 Intro to Nuke
Nuke is the powerful node-based compositing tool at the heart of the Nuke family. Whether your focus is on blockbusters, animation or binge-worthy episodic content, Nuke’s flexible and robust toolset empowers teams to create pixel-perfect content every time.
Introduction to Nuke how navigate and understand node system. By creating this simple animation using blur and transform.
Using grade node. Changing exposure.
Transform animation. Using transform node.
Making changes in curve editor.
Exercise 1.2
The idea it was to merge 3 images to create final results.
Blank blue screen used as a background
Add image 1 and merge it with blank blue background.
Add image 2 and merge it with blank blue background and image 1
Adding all there 3 images together to achive result below:
WEEK 2
1.1 Organization and Roto.
Behind the name, which evokes associations with some not very pleasant medical procedure, stands one of the greatest inventions in the history of cinema. This is the so-called rotoscope. In 1915, at a time when the film industry was still shyly crawling, two brothers - Maxi and Dave Fleischer - developed a simple device with which it was possible to see every frame of a previously recorded film, and then draw any element appearing on it.
In practice, it looked like the actor played his role, and then an animation was created on the basis of his movements. It was an extremely laborious job – frame by frame, every move had to be copied. Shooting a short, graphically simple scene took long hours of very boring and demanding accuracy work.
The Fleischer brothers used the same technology to animate other characters who won the hearts of underage moviegoers. These are the real actors behind setting in motion such heroes as Popeye, Betty Boop, or, for example, the Superman series created in the early 40s.
One of the most iconic weapons, the lightsaber from Star Wars, is nothing more than an animated element added in post-production superimposed on a film prop. The situation was similar with some shots in the film "Birds" by Alfred Hitchcock, where some of the attacking birds were "artificially" pasted into the picture.
1.2 Practice.
For this exercise we used footage provided on blackboard. By bringing roto and copy node we started to create our sequence.
By using Bezier selecting edges of the ball.
Separate the ball from others and press M to see how mask is look. Added Premult node. By premult, we cut out the roto mask. The simple definition of premult is to multiply the alpha and the RGB of the input together.
Second exercise is wat to use footage from blackboard and use same technique to select small building and follow it frame by frame.
Bringing roto node and selecting building by choosing Bezier in Roto node.
Looking by each frame and trying to look which one is not matching with our Bezier. By pressing on the view port, we can control and place selected Bezier area in correct place. Grade node is to tweak colours or change selected object. Anything from changing color to brightness or whitepoint etc.
WEEK 3
1.1 Complex Roto.
By using roto node and selecting few parts of the hand and follow each fame to separate hand from the background
All lines for rotos overlay each other to follow each line of the fingers.
Final results. All Bsplines following each frame.
WEEK 4
Basic Keying
WEEK 5
Colour and grading.
WEEK 7
Advance Keying.
This week we replace the background and clean it with roto node. We used similar techniques as during workshops last week.
Using denoise and keylight.
Clean all noises with that image.
By using Key lighting and Edge Blur set up to 3 connecting to Clamp as set up it to 0.0001 connecting to keymix node and ny using roto separating right side and left side to complete this shoot need to use couple of time and finishing wit merge node and stencil operation plus adding premult node the end. Below is finished image.
Workshop Week:
This 1 week workshop was about to do two shoot. The first was compositing the video below. First one was to add shoot over the gun and later blod for the second character who falling down after the gun shot.
Another shoot was about to clean the plate by removing tracking markers, wires and stands behind the main character.
WEEK 7
Tracking in Nuke.
WEEK 8
WEEK 9
KEY SKILLS RECAP.
This exercise we started with cleaning background. First thing it was to clean marks by bringing tracker and tracking the marks, then select roto and replace transform then add edge blur and connecting it to the keymix. Same procedures has been apply to other points and then by merge it with the matte operation do one big roto around the character use saturation and grade node on the end. By using constant background change the color and apply under with the merge node and over operation.
Removing logo by using rotopaint. Before painting frame needs to be hold at 1001. Creating logo shape by using roto then edge blur and copy.Last end was by using copy corner and merge it together by using merge in over operation with an original footage.
For my study recap I create some shoot by using footage I filmed (using DJI2mini) in Poland over the summer in Bieszczady Mountains. Lately I found online free footage with sunset time lapse. Idea was to do sky replacement roto mountains and smooth the edges after merge them together. Last touch was to play with noise and make them sort of clouds coming through the lens.
One of the most challenging in this shoot was to find birds. Becouse of the speed of original shoot they were dispersing very quickly and sometimes only visible in the one frame. It was sometimes hard to see them. I watched this footage many times to catch each bird on the sky or close to the mountains and by using roto paint remove them very carefully.
Final Script screen shoot:
Original shoot + Final shoot +fog effect by using nosie:
WEEK 12
Assessment. Preparing assets, background and monitor screen.
Assessment 1
Screens below presents progress for my comp assessment. For the lights source I used godray node. First thing it was to create roto. Then by using grade node (alpha channels) and write this expression: (sin(frame*0.5)+1)/2 make sorce of the light blink. I create red color to pretend sort of fire alarm. Then by copy operation premult with the constain red color. Nect step it was to add grade node and set up emissive for color mixing with nosie with multipy operation.
Same technique I used for front light with different setting and add volume rays effects. (I also created shape of the areas where led panel was to give more natural felling. I also used different grade section for the front lights of the car.
Volume rays effect added on the front lights. I created roto-shape for this emissive areas with god-ray node.
Applying IBK Keying.
Final Comp.
