    TASK: Exercise 3.5 Garbage Mattes and Basic Compositing

    Returning to one of the first exercises of this unit, the rotating chair, bring this into your editing software to use as the basis of a compositing exercise.

    Find a still image from the internet of an animal or object, or photograph your own.
    Bring this in to your editing software as a new layer and use the matte function to overlay this image onto your rotating chair.

    You can work as simply or as intricately as you like. The result need not be slick or believable. The purpose of the exercise is for you to explore the basics of using matte’s and to gain an understanding of compositing. If you like you can bring in a moving image to apply the matte to, but a still image will suffice.

    Bear in mind the matte feature may be called ‘mask’ in your editing software (in iMovie it is often referred to as ‘green screen’ or ‘blue screen’). Almost all editing software will have some level of basic matte or masking that allows you to work with at least two visual layers.

    Once you are comfortable using a matte/mask, you can extend this exercise further by exploring other ways of compositing. For example, try bringing in a line drawing and use a ‘multiply’ function to overlay this drawing onto your chair animation. Upload any extra experiments onto your learning log.

    The revolving chair at 24FPS. Initially I tried a slower framerate, but this gave too much jumping between frames for the masked bird to follow. I put one layer above, and one layer below the sparrowhawk so that the chair showed over the top when it was in back view.
    The Sparrowhawk: I masked this out using a pen tool, and overlaid this on top of the chair as a 3D layer, adjusting its position and orientation to try to fit the movement of the chair.

    Mirror background from Lockdown Haircut. I removed the vignette and increased the size to include only the mirror, as if the bird is looking into it. And put this as the background layer, with the chair layer set to multiply.

    Project 3.7 Ken Burns and keyframing

    American documentary film-maker Ken Burns is synonymous with an approach to documentaries using still images with a narrated voice-over where images are slow panned and zoomed using an ease-in and ease-out. That is to say, the movement starts smoothly and slowly comes to rest. Apple in fact named their ‘ease in ease out’ tool after the film-maker “The Ken Burns Effect”. You set the first ‘key frame’ (where you want the movement/zoom to start) and the final ‘key frame’ (where you want the movement/zoom to end). The software then interpolates the in-between frames.

    Adobe After Effects and Adobe Premiere allow very fine control over this movement with graph editors. But I really needed to use different images than indicated by the task to really explore this technique – see Assignment 3.

    TASK: Exercise 3.7 Keyframing and Ken Burns Effect

    Do some research about what keyframing ability your editing software has available (including the ‘ken burns effect’ if you have it).
    ● Explore this technique adding key framed movement to a single still image.
    Once you have mastered this, return to the editing project of exercise 5 (garbage mattes and basic compositing).
    ● Can you apply a key-framed move to one of the layers (either the chair or the object that you introduced as a new layer)?
    Explore Bezier curves and direct movement if your software offers this.
    Upload a short experiment demonstrating that you have come to grips with basic digital keyframed movement to your learning log along with any notes on how easy or difficult you found this process and what resources you used to help you.

    Animated fly in of Sparrowhawk with Ease-in Ease-out to the chair in freeze frame. The chair animation was reversed so that started facing the mirror ready for the Sparrowhawk to land. This was a bit tricky because of the multiple pre-compositions and blend modes. And the rather complicated movement meant I had to put in a keyframe in the middle.

  • E3.4: The Squirrel: Rotoscoping

    E3.4: The Squirrel: Rotoscoping

    Skateboarder: Watercolour Grunge effect
    Red Squirrel: Textile Effect

    This project only scratches a bit more of the surface, pending much more in-depth study of After Effects in Assignments 4 and 5. Here I take my own low resolution video and (building on E3.2 Sparrowhawk) looks at how to manipulate this as the basis for line animation and After Effects Creative Effects. As a preliminary to developing a longer and more complex rotoscoped animated narrative of different garden wildlife for SYP and also MI Assignment 5. And building on my sketchbook work to improve my initial drawing.

    This project is in two parts:

    • Skateboarder: Rotoscoping directly onto my own action video footage of Skateboarding shot on an old compact camera and experimenting with Creative Effects templates in After Effects.
    • Squirrel: Digital frame by frame rotoscoping onto manipulated iPhone video footage in Rough animator on my iPad

    Different effects were effective in the two cases, based on styles suggested by the subject matter and also differences in the form of the source footage.

    The ultimate aim will be to produce much more dynamic and engaging animation than in ‘Pig Tales’ for Visual Research – with more in-depth consideration of Disney Principles – but in an RSI-friendly way that does not take months of digital drawing. I will further develop this work into a narrative with more garden wildlife as part of Moving Image Assignment 5. I also plan to experimenting with a wider range of hand drawn (drawing on top of printouts from the rough rotoscopes from Creation FX??) and digital rotoscope styles (in AE and TVPaint) and approaches from other artists viewed in Research 3.1.

    About Creation Effects

    Creation Effects are customisable After Effects Template files created by Noel Powell (https://creationeffects.com/index.html). These can be used to stylise footage in much more natural ways, using complex combinations of AE filters and expressions to produce some very organic-looking effects.

    Footage is imported into these files, normally at 10FPS, and each of the template effect layers can be animated and adjusted to produce a wide range of effects, including different papers. Other AE effects can also be added and stacked in different ways for full customisation. I am only just beginning to explore all the different options.

    TASK

    Find a short piece of found copyright free footage from video sites such as archive.org ( https://archive.org/ ) or use your own footage as the basis of a short rotoscoped animation. The duration of your sequence is up to you. Choose a rotoscoping technique you would like to try such as: using a projector, drawing by observing footage frame by frame, tracing paper over a screen, printing out frames and drawing on them or digitally drawing directly on each frame using computer software. Work fast and loose and be playful – see how far you can depart from the source footage and where the process can lead you.

    Rotoscoping is a key part of my practice that I want to develop in depth. This project is part of a project ‘Garden of (Eternal) Mindfulness for SYP. This develops preliminary ideas for a longer term cross-media body of work taking a tragi-comic view of the joys and challenges of wildlife gardening. This build build on MI Assignment 2 Summer Synaesthesia, and also a sketchbook that develops my wildlife sketching skills.

    The rotoscoping project here builds on experiments with rotoscoping in TVPaint line and shape animation from found video for Visual Research Module. Since that project I need to change my pc animation system because my old laptop is now too slow to use TVPaint.

    It also builds on my research in Moving Image Research Project 3.1 Evaluating Rotoscoping.

    Skateboarder: Action Video Creation Effects

    These were my first experiments with Creation Effects – before I developed skills in line animation in Visual Research module. After watching videos about approaches to rotoscoping techniques on Linked In Learning and You Tube, I was interested in potential approaches that could minimise drawing and hence RSI risk.

    These effects are templates with multiple adjustable and customisable layers. But these require a good understanding of After Effects to really get the best effects. Nevertheless, even when used as they are given in the template, they do provide interesting ways of stylising even pretty bad and low resolution footage. If the style is selected based on the meaning and purpose of the footage.

    Original video shortened with enhanced colour and contrast in Premiere.
    Pencil 1: I find this pencil sketch effective as a stylised documentary version of the footage.
    Coloured Pencil: I find this coloured pencil rendering interesting as a cartoon style. I like the softness of the colours and outlines and the boil effects.
    Coloured Ink: This is a much darker and fractured type of image that might be effective for political or darker subject matter – it reminds me of the animation of Catherine Anyango. The small image export was unintentional, but adding a black or coloured frame outside the frame produced by the effect itself could add to the impression of watching something unfolding on a screen.
    Half tone patterns: this posterises the colours but there would need to be a reason to use this style. It might be more effective just in black and white.
    Textiles: this was the first time I have used this effect. It is interesting, but the textiles used seem to be very sensitive to changes in tone. Would need to have a good reason to use this effect, and also the figure would need to be in a constant tone and colour.
    Watercolour Grunge: This is one of my favourite effects. On this footage I like the addition of the colour and modern/retro? (depends on one’s age I expect) feel.

    Squirrels: grey or red

    The effects also work well on digital line and shape rotoscoping.. As well as the featured Red Squirrel textile animation above, the sketch and monochrome watercolour grunge effects also significantly enhance the original flat animation, adding markmaking and textural interest.

    But again, to get the best effects the original templates need to be customised – animating the strength of the effects as well as altering the parameters – so that excessive ‘boil’ is more controlled. The animations can also be further manipulated in After Effects for colour controll, image stabilisation etc.
