NUKE WEEK 11
This week, Mr. Gonzalo shared with us “Real-life scenarios in production”, a necessary and mandatory step when checking before the table work and when submitting the work. It’s very important and I think that every time I finish a job, I’m happy because it’s done. I release it in a hurry and don’t check it carefully. This may cause some problems in the future.
After that Mr.Gonzalo introduced Temp, Trailers, Finals, and QC. this is the film production phase of the composite. The work is like an assembly line. We had to check each one carefully after we finished it. That way we don’t make mistakes in our work.
After that, the teacher introduced some positions in the job and things to pay attention to. The studio is a team. We need to be clear about our position in the team. Do a good job of communicating with others. Be clear about what you need to do and how to accomplish these tasks so that I can work with as few problems as possible.
Nuke week 10
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 week 9
This week we learned about planar tracking, first, we learned how to arrange the nodes correctly. Due to the different order of arrangement may produce different results.
Next, we learned about Shuffler Node, we can change the channels of RGB by Shuffler Node. We can rearrange the different color channels of a texture to the nodes of other color channels.
After that, we started to learn plane tracking. We used Planar tracker, which works very well. It helps us to change and replace images easily. We first roto the area we want to replace and track it. Then we use display_planar_surface and display_grid_lines to adjust our selected area. Finally, we replace our image with CornerPin.
Finally, we also learned about the Defocus and ZBlur nodes. These two nodes can change the focus position. Thus, area blurring is performed. This is very useful in video editing.
Group Production
The first one is to use the theme of Harry Potter to make a short film about our travel to the wizarding world.
My story is that one day we came to the 9 and 3/4 station, and then a portal appeared at the station. We entered and entered the world of magic. And use the magic war to fight against each other.
WEEK7 EMERGENT TECHNOLOGIES-Motion capture
Motion capture is a technique for recording and processing the movements of people or other objects.
Traditional three-dimensional animation mainly with the help of MAYA and other three-dimensional software, such as the production of animation effects, its animation character action also through the animator in the late use of K frame adjustment. This approach requires a lot of human, financial and material resources and is not very efficient. And some of the movements are too complex, and the effect after the k-frame is often unsatisfactory. The most obvious advantage of motion capture technology is that it can significantly improve the effectiveness of animation production. This is because since all movements are performed by a human being. This allows even very complex movements to be made. The computer can also simulate them, so that the best results can be achieved.
Thanks to the creation of motion capture technology, more science fiction films have been brought into our world. For example, the princess of the Nami tribe in the earliest Avatar, the fierce Gollum in The Hobbit, the gangly stuffed bear in Teddy Bear and many other classic characters. They were all brought to life by motion capture technology. And it’s not just in films that motion capture technology excels. It is also used in games and other areas. EA’s NBA2K and Fifa, for example, use motion capture technology to record the movements of athletes in their games. This gives players the most realistic experience in the game.
In summary, motion capture technology currently has outstanding advantages in all areas of creation. And it has influenced the whole environment of special effects. It will also have even better developments in the future.
Nuke WEEK 7
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.
Nuek homework
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.
Nuke week 8
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.
Maya week 8
This week Maya focused on learning how to layer renders for import into Nuke and to make the whole face mapping more realistic.
First we found texture maps online that resembled flesh and then used photoshop to blend the textures with the face material. This gave the figure a flesh like texture on the face. After that I added a few more scars to the face. This also made me feel very happy with the result.
Afterwards, using layered rendering in Maya, six different layers are added to the model. Batch rendering was then performed. Import the sequence frames into Nuke for colour grading.
Light in Maya is also very important. I have created two point lights and one side ambient light. This makes the whole model more realistic.
