Instead of doing a video copilot tutorial on the blemish removal, I noticed Andrew’s was a little out of date, and an overall sub-par example, as the girl in the video looked good from the start.I did find a great tutorial on beauty work in nuke by Stephan Fleet here:
I especially liked this tutorial because it was organized, had great techniques, like the erode in then erode out to fill in colors, and also because he quickly goes through a little Mocha technique which I thought was intriguing and made me want to learn mocha further to help me out with roto/planar tracking in the future.
So please check that out as it is a much more thorough tutorial than I’d be able to produce!Also check out Stephan Fleet’s site for more of his tuts here:
Hopefully I’ll be moving on to more tutorials soon. I’ve been getting into some python scripting and menu customization and will be coming out with a Compositing Guru Toolkit soon. So stay tuned for that and much more.
Here I reproduce video-copilots “3d compositing” tutorial # 6 in nuke. I am using card3d’s instead of regular cards. Here are some Spark Notes on the video:
Recap, Things to Remember
1.) use card3d instead of card where you can – renders a lot faster (no scanline renderer)
2.) The uniform scale of the card expression is:
3.) use an axis node to control the cameras pivot
4.) premult the depth from the card3d by the alpha
5.) set merges to “also merge” the depth channel, to layer the depths
6.) us the focal plane setup in the zblur and animate the focus plane,
depth of field and maximum for a shift focus
In the “Uniform Scale” of Card or Card3d:
Type this Expression:
The Default Settings of a camera in Nuke are always the same,
even when the project settings global format changes.
The cameras h-aperture and focal length are always:
focal lenght: 50
The first part of the equation gets simplified by us since it is
always the default and only changes if we import the camera
or change it ourselves. Therefore the new equation is:
Took a little bit to figure some of this out, I can probably say it’s easier to do this tut in AE, but then again there is a lot of power coming out of the card system in nuke. At least you can reproduce the results! To each his own. I really hope you guys can use this info, especially the equation!
Demonstrating how to do camera shake inside of Nuke, as well as Introducing my Motion Tile Gizmo. I really enjoyed making this one because of the problem with having no motion tile option in nuke, then problem solving the best way I could. I think that this tutorial is a great example of why I started this series, to bridge the gap between AE and Nuke and to come up with clever solutions to problems like missing tools.
A quick overview of bugs Nuke has with .mov files, and how to work around them if you must use them.
It is always a better choice to convert to an image sequence. Read nodes will get bogged down when rendering because the .mov reads can only be single threaded, where as an img sequence can use multiple threads when rendering, making speeds much faster.
1.) hide the postage stamps on the reads of .mov files if nuke is crashing and freaking out
2.) when rendering, if you receive a .tmp error and runs through the timeline without rendering anything, try checking “render in background”
3.) use img sequences in nuke when you can
I chose a group instead of a gizmo because it is easy to just drag and drop into any script without any fuss and will work on multiple machines or networks. Gizmos will break if it cannot link to the main file properly. Anyways just drag and drop this guy into the script and voila, deinterlaced video.
Let me know if it works for you, if it has any bugs, or needs any updates.
It’s a good Idea to deinterlace the video and to convert the .mov provided into an image sequence, and I will tell you guys how to do that in the next video.
This is my first tutorial, I am sure I will get better as I go along, but please let me know some feedback. Too fast? too slow? to boring? etc. I’d be glad to hear. Thanks and I look forward to posting more videos.
I will keep this a brief mission statement. For awhile now I have heard the many arguments of artists on which program is better, after effects, or nuke, and how there seems to be a very fine line and not too many artists who cross over to both worlds.
I decided to bridge that gap, it is obvious the power of both nuke and after effects. I think one thing after effects has a leg up on is the ease of access to great tutorials, specifically from VideoCopilot.net. Andrew Kramer and his team did an amazing job letting people like me and others learn AE easily.
I’d like to take the VideoCopilot tutorials and “convert” them into nuke tutorials. I will start at the bottom and go all the way through. so those familiar with after effects from Andrew’s videos will have no more excuse to jump into nuke and vice versa.
I must say I have not touched after effects much in the past few years, so it will be a Journey for me to not only learn the VideoCopilot’s tuts and techniques for after effects, but to then figure out the best way to get similar results using Nuke.
I think it will be fun and I hope everyone will learn a thing or two.
