While working on balloon festival 3, I encountered many problems and solved them one by one.

1. The first thing I considered was the lightning effect in the background. I wanted the lightning from the sky to be behind the mountain, but in my first few attempts, the lightning would also turn to be in front of the mountain after the balloon had turned. Finally, Ruijia and I discussed the use of multiple layers of merge. By using the right grouping I was able to achieve the goal by using the roto of the mountain twice, which was successful.
2. Different places so the colours were different. I adjusted it to blue-white by Color Correct, but the glowing effect I never got to try out the.

Poster’s exercise is based on roto to bring the two images together. Also the pole is eliminated with roto, which completes the shading relationship between the pole and the poster. Although simple it is a very useful exercise.

We learned a new way of creating a tracker, and at the same time used Tracker to create Transform_Stablize. CornerPin2D3 transform shape.

This assignment was another exercise for the Roto node. Firstly, we were asked to roto and track the part of the screen where the finger was occluded from the screen. Afterwards, we used a gradient to change the screen at the moment the finger touched the screen to show a second image. This long strip of images has to slide up and down depending on the interaction between the finger and the screen. It uses key real animation frame animation in the morph node.

This is my first fantasy balloon test, I chose lightning effects, one of the lightning effects uses the exact same movement path as the balloon for the node, the other lightning effect is behind the mountain On the way to do this test I found a problem, because my balloon goes around from behind the mountain to the front of the mountain, this is achieved by using the shap keyframe in the roto node. But when the winter balloon goes around to the front of the mountain, the lightning behind the mountain also appears in front of the mountain because of the key really change in the delete but when the winter balloon goes around to the front of the mountain, the lightning behind the mountain also appears in front of the mountain because of the key frame change in the mountain.

In the adjustment of the color of the picture, I used ColorCorrect and Grade to adjust the values of the RGB channels of the picture. My intention is to have the background’s backlit environment affect the color of the plane. At the same time, the contrast is enhanced to make the sunset/sunrise in the background more visible and beautiful.

During the process of combining the balloon with the background, my balloon became transparent. After trying and watching the tutorial, I figured out that it was because the alpha channel of the background material was not set to Auto Alpha when it was imported. Eventually, I finished merging the footage.

Practice using Roto to key out portraits in Nuke.

Faced with the theme of “time”, I chose to photograph ice cubes. In total, I recorded the melting ice over several hours from 130 photos at three different depths of field. Then pick the 7 photos that best fit Moodboard 1. Three of the photos 3, 4, and 5 are different parts of the same depth of field. The three of them are combined into a complete photo, but at different times.

In addition to the ice cubes, the sun’s light is also part of the representation of time changes, the angle of the ice cube’s shadow, and the brightness of the light.
