We spent the first week of the second semester learning about 3D systems in Nuke, and how to use cameras and import models. Then we practiced the use of the CameraTracker node. You can use these points to position the 3D scene.
This week we’ve learned how to use Defocus Nodes and Shuffle, and RotoPaint’s various tools. Use a variety of ways to remove and modify scene objects in your video.
Because the removed part of the paper on the wall overlaps with other papers, there will be obvious gap after removal, so I use Rotopaint to fill in the gap drawing.
This week we learned the details of plane tracking, including how to use palette and roto to make the replacement of plane tracking more realistic. In the video of the Balloon Festival, I used color correction and keyer to assist the special effects of rain and snow, making it have some fantastic colors.
I learned moving point tracking this week. I combined Crop node and CornerPin to change the shape of mask to match the green screen of mobile phone screen. The final output result is not very satisfactory. I guess it can be solved by changing the green screen background into black to solve the discomfort caused by incomplete overlap. And it requires extra attention to the timing of the finger slide to match the mask image animation.
This week focused on color tuning and color correction, learning about the use of RGB and Alpha channels. And the effect of gamma and other parameters on the image.
Learned how to use Reformat node and Grade node.
This week you learned more about how to use nodes, as well as the very important Merge node, and started to synthesize videos using the exr balloon files provided by the Maya course.
Tracing and layer overlay are also used.
This week you learned how to use Roto, dynamic blur, proper workflow, and more.
This week introduces the difference between After Effect – Fusion-Nuke.
And detailed introduction of Nuke software interface and node use.
This week we’ve looked at the effects of light quality, color temperature, composition and Angle, and photo size on a live shot.
This was the first week of Nuke’s course, where we learned about photography and the importance of color, exposure and lenses, perspective and distortion. File format, frame rate. Video management and so on.
I don’t have a specific concept of time, but I like to take picture for the clouds and the sun, which may be another way to witness time.
