During this nuke class we learn how to clean up markers from someones face. We also learn how to add textures and how we use the technique to add some corrections as well. We start off by learning that we need to degrain the footage we are using before removing the markers. The idea is to first degrain the footage then remove the markers and then apply the regrain to the finished plate. For degraining and regraining we have different techniques we can use. We can denois the plate by using the “Merge (Minus)” node followed by the “Merge (plus)” node. Or we can use the “F_ReGrain” node This is a more precise way to degrain/regrain.
After Learning about how to degrain the next thing on the list was about how to Patch correctly. We have learnt about how to patch before but now we learn how to work with uneven lighting. As normally not everything is even we work with how best to remove these trackers. To get the Low frequency we use blur to tackle it and for the high frequency we use from, after we use the plus “merge” node to merge them.
For this class we got assigned a Small homework assignment regarding the patch clean up work. For this homework I used the techniques we learned during the class. I created a denoised plate and I did a simple track for each separate tracker point on her face and Rotopainted this and used the roto blur tool to individually blur the parts that needed the low frequency to work. I kept it simple Since this video does not have big light play.
