Nuke-Balloon festival

By using various functional nodes in Nuke, integrate balloons into an ordinary video of a mountain, making the footage more engaging and dynamic.

  • 241024-Concept art

Inspired by the reference provided by my teacher in class, I reflected on the styles of balloons for the Balloon Festival. I noticed that the reference featured a large balloon on top with a basket below that could carry people. This combination reminded me of the movie Up, where a house is lifted by a lot of balloons. This concept aligns perfectly with the theme of the Balloon Festival. Therefore, I hope to use this as inspiration to design my video.

Use Roto and Tracking nodes to separate the mountain from the entire video.

  • 141124-Merging and color

Based on my concept art, composite the corresponding sky into the scene and adjust the overall color accordingly.

  • 211124-Modeling and composition

I created assets in Maya similar to the house and balloons from Up, applied materials, created animations, and finally rendered a sequence of frames.

To make the scene more interesting, I also decided to add the character of Russell, placing him in the foreground on the left side of the scene. This not only aligns the video more closely with the theme of Up, but also adds depth to the composition. Therefore, I created his model.

In Maya, after setting up the layout and lighting and finalizing the camera angle, I performed layered rendering for the two models.

I hope to make the video more engaging by adding animations and creating more narrative elements. Through the movement of the models, I want the audience to discover an interesting story.

I created more animations for Russell to showcase his emotional changes.
