This week, we continued to review roto. We still need more practice, especially when it comes to actual details. For the picture with only slight tremors, we can first track and match, and then copy the track information to roto’s transform. When we do the project for the balloon festival, this method can help us figure out the big mountains in front of the materials.
The Alpha channel is a special layer for recording transparency information, which refers to the transparency and semi-transparency of an image. Alpha is very important for processing material in nuke. We need to find the Alpha information of the materials and then adjust the color of the materials.
