Week 5:Balloon Festival

In this lesson, we learned about tracker.

2D tracker that allows you to extract animation data from the position, rotation, and size of an image. Using expressions, you can apply the data directly to transform and match-move another element. Or you can invert the values of the data and apply them to the original element – again through expressions – to stabilize the image.

Combine alpha

Channelmerge

The ChannelMerge node lets you merge together one channel from each input and save the result in the selected output channel. All other channels are copied unchanged from the B input.

If no A input is connected, both channels to merge are taken from the B input.

By default, ChannelMerge combines the inputs’ alphas.

Grade (pressing G on Node Graph)

Lets you define white and black points by sampling pixels from the Viewer. Setting the brightest parts of the image to pure white and the darkest to pure black in this manner can help you add punch to overexposed images, for example. You can also use this node for matching foreground plates to background plates.

To sample pixels from the Viewer, click on a color swatch to the right of the control you want to set. The eye dropper icon appears. In the Viewer:

  1. Ctrl/Cmd+click to sample a single pixel from the node’s output.
  2. Ctrl/Cmd+Shift+drag to sample a region of pixels from the node’s output.
  3. Ctrl/Cmd+Alt+click to sample a single pixel from the node’s input while viewing its output.
  4. Ctrl/Cmd+Alt+Shift+drag to sample a region of pixels from the node’s input while viewing its output.
  5. Crtl/Cmd+ right-click cancels pixel selections.

Clamps

This node constrains, or clamps, values in the selected channels to a specified range. By default, it clamps all channels to values between 0 and 1. This can be useful for ensuring that the input’s blackest blacks and whitest whites will be visible on an intended display device, or for restricting data fed to a subsequent node that does not support numbers outside this range.

Week 5 :Politics and Documentary in film and animation

Animated documentaries are a form of moving image that combines animation and documentary, and I think that even through animation as a form of artistic expression the nature of documentary still exists, and the answer is Definitely.

Walking by the Canadian animator and artist Ryan Larkin made an indelible mark in the history of animation with its innovative combination of drawing and colour wash techniques. But as far as Walking is concerned, I don’t think of it as an animated documentary, walking is the subject and animation is the form of its presentation. He doesn’t refer to specific times and certain real-life cases, nor does he tell a story, he just animates the moments of different people walking from different angles, but of course, there is no denying that walking is the most common thing for most people, and the author adds his personal touch to it, making it interesting and advanced.

I agree with Honess Roe’s idea:

‘animated documentaries do not easily into the received wisdom of what a documentary is’

Animated documentaries have overturned the public perception of traditional documentaries. Compared to traditional documentaries, animated documentaries give people more scope for imagination. In terms of character design, animated documentaries highlight the characters’ characteristics through elements such as their appearance and expressions, which visually help viewers to distinguish and understand them.

Week 4:Rotoscoping and Tracker

This week, we learn how to roto and track from a vedio.

How we can remove the alpha?

Shuffle

  1. rearrange up to 8 channels from a single image (B input). For example, you can use it to swap rgba.red for rgba.green, and vice versa,
  2. rearrange channels between two separate nodes (A and B input), like a foreground and background branch,
  3. replace a channel with black (removing the alpha channel, for example) or with white (making the alpha solid, for example),
  4. create new channels.

Premult

By default, Premult multiplies the input’s rgb channels by its alpha (in other words, premultiplies the input image). You may need this node when:

  1. Merging unpremultiplied images. Because Merge nodes in Nuke expect premultiplied images, you should use this node before any Merge operations if your input images are unpremultiplied. This avoids unwanted artifacts, such as fringing around masked objects.
  2. Color correcting premultiplied images. When you color correct a premultiplied image, you should first connect an Unpremult node to the image to turn the image into an unpremultiplied one. Then, perform the color correction. Finally, add a Premult node to return the image to its original premultiplied state for Merge operations.

Typically, most 3D rendered images are premultiplied. As a rule of thumb, if the background is black or even just very dark, the image may be premultiplied.

Roto (pressing O on Node Graph)

The Roto node is an optimal choice if you’re doing rotoscoping only – it allows you to create and edit Bezier and B-spline shapes.

The toolbar on the left side of the Viewer includes point selection and manipulation, and shape creation tools. Click and hold or right-click on a toolbar button to open a sub-menu to select any of its available tool types. Options related to the current tool appear in a toolbar along the top of the Viewer. Click on a toolbar item to cycle through the available options for that class of tools.

As a general workflow guide:

  1. Select your tool from the left-hand Viewer tool bar.
  1. Use the Roto tool settings above the Viewer to adjust the tool’s properties.
  2. Draw your shape or shapes:
  • Click in the Viewer to place points. You can drag while clicking to pull out Bezier handles or adjust B-Spline tension.
  • Ctrl/Cmd+drag to sketch the shape freely.
  • To close the shape, click the first point or press Return. To leave the shape open, press Esc.
  • Ctrl/Cmd+Alt+click to add points to an existing shape.
  • To increase the smoothness of a point, select the point and press Z.
  • To cusp a point, select the point and press Shift+Z.
  • To delete a point, select the point and press Delete.
  • Beziers: Shift+drag on a tangent handle to snap the opposite handle to the same length. Ctrl/Cmd+drag on a tangent handle to move it independently of its opposite handle.
  • B-Splines: Ctrl/Cmd+Alt+drag on a point to adjust its tension.
  1. Select a shape using the Select tools or the shape list in the control panel.
  2. Use the control panel to adjust or fine-tune your shape(s).

Copy (pressing K on Node Graph)

Replaces channels in the B input with channels from the A input. You can use a mask channel to indicate which input is used for each pixel or whether both inputs should be mixed for some pixels.

Week 4 :Innovative and emergent practice

The form of Severance Intro Title Sequence is 3D Animation 

Severance focuses on the balance between life and work and is set in a company with memory-cutting technology.

The animation illustrates the protagonist’s life struggle between professional and personal predicaments. Work personality and life personality constantly shuttle and pull in the grid.

The work represents the mystical journey of these different identities memories of experiences, grief, loss, and control in one body through the use of surrealism and subtle ironic humour. The protagonist switches from one scene to another and the different scenes are linked by objects that working people use throughout the day, lifts, hoovers, beds, etc.

In terms of visual expression, the strong minimalist modernist aesthetic, the warmthless cold light, the repetitive approach and the symmetrical composition show the rules and limitations of the workplace, depicting a working man like an emotionless machine working non-stop on an assembly line.

The scene in which people are being poured out of the coffee cup is my favourite. I think he depicts the state of people in the workplace going with the flow through the ‘labour and capital perspective’, implying some kind of control. People looking and running, trying to escape but unable to do.

In the use of technology, Firstly the main characters were created by 3d scanning, and based on 3d meshes texturing the skin and combing the hair in Houdini software. Secondly, Cloth creation and rigging were also done in Houdini and Marvelous Designer, with the rest being a combination of motion capture suites from Xsens. finishing touches in Houdini and Cinema 4D, and finally rendering in Octane.

The molten and sticky effect made through model deconstruction enhances the expression of the chaotic and muddy state of being caught up in work and life. This state, coupled with the slow and urgent music, makes people naturally immersed in the bizarre atmosphere.

There is a lot of symbolic expression in this animation, and the use of symbolic elements to make the images and expressions more interesting is what I most wanted to learn from this animation.

Week3: Digital Compositing and Nuke sofeware interface

In this lesson, we learned about what dose a digital compositor is.

I like this diagram, it interestingly explains the process of making 3d animation.

We learned the basics of Nuke such as import and export formats, colour modes, and other nodes for different purposes.

Import and Export

RGBA

ColorWheel

Generates a color wheel image. Inputs and Controls,the colors on the bottom pf the node show all the channels contained in the node.

CheckerBoard

Generates a checkerboard image that you can use as a placeholder for a texture or background. If you enable proxy mode the board may not match the full resolution version, because the boxes are rounded to the nearest pixel. Inputs and Controls.

ColorBars

Generates a Society of Motion Picture and Television Engineers (SMPTE) color bars test pattern, useful for color management. Inputs and Controls.

Week 4: Hot Air Balloon

After completing last week’s modelling I painted the texture for the hot air balloon, the texture was made by myself in AI with the letters Gina, which is my English name. Its style is as relaxed and happy as a party. This model will be used in the Nuke course.

Week 3: Modelling tools

surfaces tool-EP curve tool

revolve tool

We embarked on more complex projects, making glassware and modelling a hot air balloon. For the former, it was important to place it in a suitable environment so that the glassware would blend in with it. There is a wealth of detail in modelling a hot air balloon, such as the chains and clasps that connect the balloon, the engine and tubes are also essential parts of the balloon, I made the passenger section of the balloon into a fence style, I like the neat and orderly design.

Week 2:Cinematography Foundation:City

‘City’: I couldn’t think of an exact subject at first, I just randomly recorded some life clips,until I wanted to add background music to this 20-second video and I heard the song sparks. It suddenly remind to me that pets, art, music, and architecture are the sparks in our lives.

Week 3 :Narrative structure

https://www.imdb.com/title/tt1748122/mediaviewer/rm284647936/?ref_=tt_ov_i

I picked the movie Moonrise Kingdom. I am a fan of most Wes Anderson films. I am always attracted to the colors and symmetrical compositions and the stylist of the characters in films.

The film is about the innocent feelings of children, Suzy and Sam, who communicate as pen pals by writing letters. They have different character traits.

Sam’s personality represents all the qualities of the logical, he’s a member of the local boy scouts, which in many ways tries to mimic the discipline of the military, he knows how to read and make maps and he shows an interest in the painting of the landscape.

Suzy love to touch with the fantastical and artistically creative aspects of life as shown through her interest in numerous fantastical children’s books and her attachment to her magical binoculars.

What they have in common is that they have difficulty getting along with the people around them. Suzy and Sam are also trying to understand each other’s world, they are both Ignorance children trying to find another person and place where they are happy, but all the adults are trying to tear them apart.

Archetypes:

  • Hero: Sam Shakusky
  • Mentor: Suzy Bishop
  • Threshold Guardian: Scout Master
  • Herald: Rainstorm
  • Shapeshifter: Scout Member
  • Shadow: Narrator
  • Trickster: The storm rescue operation
  • Allies: Captain Sharp

Story Arcs:

Prologue

From the lining of the tent to the color of the paper on the bulletin board, the screenplay is full of detailed descriptions of the world, each character is doing something else when we meet them, going about their normal routines before getting roped-in to the story. Until it was discovered that sam had left the scout group.

Conflict

The narrator gives us a tour of the island and foreshadows the coming storm,

Narrator: “We are on the far edge of black beacon sound famous for the ferocious and well-documented storm   which was driven on the east on the fifth of September —in three days.”

Discovery of sam’s disappearance and then the search for him begins.

Rising action 

We meet the khaki scouts and see their potential for violence as they search for sam while carrying Very large very dangerous weapons. When Suzy and Sam encounter the Khaki Scouts,  We already know the cast of characters, the scope of the world, and the looming threat.

And This film moves the plot along by further elaborating on the threat:

One of the scouts is stabbed by Suzy and the dog is killed. I felt bad for the dog being killed, but these two scenes further the plot and compound the way the threat and lack of security. They go through a series of escapes and adventures to find a suitable place to land but are eventually discovered. 

Climax

They run away again, this time in a rainstorm, Suzy and Sam climb to the roof to try to escape, there is a real sense of danger. their willingness to die for their love is impactful. Throughout the storm rescue operation, we can see from the expressions and dialogue of the characters that everyone is in a state of high tension. Falling action.

falling action

After the storm, Narrator, Gives some background information.

Denouement

Eventually, they found a suitable way to see each other.

The film had a very distinctly interactive cinematic language, it makes you very sure you are watching a film, the narrator speaks to the audience, interacts with the camera to explain the film’s message,  the audience can feel the abundance of emotions but still retains a sense of distance and needs to actively participate to identify the emotional life of the characters.
