Lightning Effect

Throughout the process of making my final production ‘Fast Man’ I noticed that the speeding effect I applied wasn’t realistic enough and it didn’t achieve the concept I was expecting/ going for. To upgrade my speedster effect I researched for Lightning basic Tutorials so I can add a lightning effect in my speed-motion just like the effect Marvel uses on ‘Flash’. (See lightning tutorial Video below)..

iLecture 7


The lecture is base on 2D and 3D tracking, also known as Match moving. In cinematography, match moving is a cinematic technique that allows the insertion of computer graphics into live-action footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot. The term is used loosely to describe several different methods of extracting camera motion information from a motion picture. Sometimes referred to as motion tracking or camera solving, match moving is related to rotoscoping and photogrammetry.(Tim Dobbert, Sybex, Feb 2005) Match moving is sometimes confused with motion capture, which records the motion of objects, often human actors, rather than the camera.


Match moving has been around since 1985and initially used in one or two points to track. It was first used were in the tracking of missiles-implemented by the US Defence Dept. The earliest VFX was used perhaps in 1985 at the famous NYIT graphics lab

Motion Tracking vs Motion Capture uses the same techniques but they’re not the same. Both is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robotics(Goebl, W.Palmer, C. 2013). In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2D or 3D computer animation.

Main notes:

  • Motion Capture uses a lot of cameras to  get a full 3D track and then captures the motion on a 3D rig.
  • Tracking gives a good insight into how mocap can work, and how you can go about attempting it.

Difference between 2D and 3D tracking

3D motion tracking also called “match moving” is used when you need to composite elements into a 3D scene. For example , you shoot some footage, and you want to put something in afterwards, in post production. 2D tracking only looks at x,y translation coordinates, +/- other stuff like rotation, sheer, perspective. But 3D tracking adds z-space (depth) , by tracking objects and re-constructing a 3d scene with 3d coordinates, so everything lives in 3D space, in a 3D model, instead of a 2D layer.

Issues that my occur with tracking

To obtain a good tracking the choice of camera is important, and the scene/composition needs to be clear and bright (lighting) cause shadows will mess with the tracking. Fast movement may cause tracking nightmares in slow cameras and the tracking markers becomes blurred and unreadable.

Further Research 

After watching the lecture I went on and researched more on Visual examples about Match moving, 2D & 3D tracking and Motion tracking & Motion capture. (see below)

Film riot has the best tutorials ever and so I obviously went and searched for 2D & 3D tracking videos and i came across to this one. The Video shows some basic and cool techniques when using tracking with texts with the motion of objects.

The 4:17 minute video shows some cool Motion tracking and Motion capture scenes and behind the scenes of movies like The Hobit and Lord of the Rings and even in video games nowadays they’re using real life actors the act out the motions and then they track the motion so they could animate it.

iLecture 6


The iLecture topic is about Rotoscoping and Chroma keying fundamentals. Basically Jarrad explains the the basics, Techniques and most importantly the things we need to avoid when using Chroma Keying, for example something i can relate to what Jarrad mentioned is bad lighting and shadows on the green/blue screen which results to poor keying. The lecture continued with the definition of rotoscoping and the techniques tht we can imply in to our compositions and things we must not do in compositions, like masking a motion image with so many anchor points can be difficult when animating per frames. Masking can take a lot of time but the end result is so worth it. Speaking form experience. Overall the lecturer was on point to what i’m aiming in some of my scenes and was well explained.

Digital Image Compositing – Rotoscoping and Chroma Keying, Jarrad Gittos. Jul 29, 2013.


The lecture showed some examples of what we need to avoid when using Green-screen, like:

  • Blond hairs tend to make the green screen split cause the hair type has little contrast for keying and that can result to missing details.
  • Make sure the green screen light doesn’t bounce on the actor cause when keying the green light on the actor will be cropped too.
  • Most important one is clothing colour. The actors clothing should not be green or have any elements/accessories that can affect the keying process.

Blue screen is best to be used for out door scenes rather than a green screen cause outdoor environments are filled with green colours and that can affect the keying. Again the actor should not wear anything blue when using the blue screen. A major point Jarrad showed was to make sure the green and blue screen are evenly lit (see screenshot below)…Screen Shot 2015-10-28 at 11.25.32 AM

The small illustrations is a demonstration on how to use and balance lights in our compositions when using chroma keying.

Rotoscoping is one of the main techniques i’m using in my project and the section that Jarrad covered was interesting to learn about the history ‘Betty Boo’  and how its was strongly used in animations compared to nowadays almost very movies are using rotoscoping to create realistic compositions.

Further Research 

In my Test video 3 I was able to produce a cool teleportation effect using Rotoscoping using two footages and merging them together by using the masking tool, (See image below)…Screen Shot 2015-10-28 at 8.03.06 PM

To achieve the cool and realistic rotoscoping effect I researched on the basics of masking techniques and how to blend the character/images after masked using feather and colour correction. The frame by frame path was hectic and took alot of time but the end result are always worth it, thanks to the tutorial video on (see video below)…
