In this week’s edition, Mr.Glanzo taught me to use the roto paint node to clean up any excess objects in the scene. The difference between this Roto node and the others is that this node is paintable and I can easily clean up unwanted objects in the scene with a brush, just like an eraser, to quickly erase them.

This image was cleaned up by this method.

This method starts by using the clone tool in the Rotopaint node to find a matching color and then apply the paste to the object you need to clean up. This is like the imitation stamp tool in PS. As you are only modifying one frame of the picture, you need to use the Frame Hold node to keep the whole video cleaned up.

The teacher then taught a second method, this one using MatchMove to do a quick clean-up of the things that need to be cleaned up. This method first wants to keep track of the clean-up target. Afterward, MatcMove is used to clean it up. This method is a bit quicker.

The last method is to track the object area first and then stabilize the scene before shuffle, roto draw. Then we crop the area we want to clean up and move it through the tracker to match.

nuke, this week was spent learning the node of colour grading, and the different modes of colour grading, and rendering different effects, and finally compositing and exporting after the colour grading was done.

The nodes merging and reformat are mainly described here. Here the two screens are mainly merged. The final output is performed.

This is where the node premulty is introduced; the main function of premult is to multiply the input rgb channel by its alpha.

The main focus here is on the several colour modes and the main features of each one.

The final assignment was to make the two scenes more natural by toning them. I changed the colours of the planes and the contrast of the background to give the whole scene a more natural look.

This week’s assignment was to replace the screen on the phone.

First I trace the phone screen and then bake the path. The replacement phone screen is then replaced onto the path.

Afterwards I rota the hand due to its obstruction. with the roto, the roto and the video are copied together. This way the hand is not under the replaced object when it touches it.

Finally, make the adjustments to the replaced object. Finally the entire screen of the phone is replaced.

Nuek has been learning mostly about track and replace this week.

First we start by keeping track of the items that need replacing. For example, this one needs to be replaced by a TV. First we track the four corners of the TV.

Once tracked we can bake paths to make our objects follow the tracked path. This allows us to replace items. We can also edit the replacement items by using properties such as deformation.

This week’s Nuke was mostly about learning Roto and tracking.

First we start by intercepting the head of the figure using roto. This will give us a separate Alpha layer

We then track the surrounding columns in turn via the tracker node. In this way each pillar has its own corresponding Alpha layer. This also lays the groundwork for the replacement later on

After that I traced the whole person’s arms as well as the legs. Through this lesson I became familiar with the use of Nuke’s roto and tracker nodes. All in all it was a very productive session!

Nuke is the first time I have come across this software. The teacher started the class today with an introduction to the whole Nuke interface. Then we were introduced to the different dose of Nuke.

This lesson teaches us how different nodes can produce different effects and how to use them to adapt our own work. Examples include colour, shape, size and transparency.

Here is a change to the colour

Here is a curve to make the video blur smoother.

Here is the page where the keyframes are observed. From here you can also make better keyframe adjustments

This week was Nuke’s first class. In this lesson the teacher focused on the prep work for Nuke. The main focus was on the principles of the camera used for filming. He introduced the three most important elements of DSLR shooting, ISO shutter and focal length. The teacher showed how different camera angles and different filming equipment can produce results. This allowed me to fully understand the meaning of most film shots. It also paved the way for post-production special effects. I hope I can produce better visual effects in next week’s class.
