Export Nuke's retime information To 3D packages: This is happen while working with production. In most cases retiming is done beforehand or at the end of a comp. Some time shots getting retimed after Match-move is done. By that time Nuke's retime data (curve) will help to match the tracked camera to new retimed plate. Here is the trick to export nuke's retime date (curve) to 3D packages such as maya, max, Houdini etc. Here im explaining how to export nuke's retime curve to maya. Constant re-speed. I want to retime my input by 200%. Add a retime node and change the speed to 2. Don't forget to change the filter option to None . Retime node doesn't generate retime curve at all. So note down the output range. It changed from original range 1001 - 1042 to 1001 - 1021. Which means our input ended with 1021. Add a TimeWarp node and set keyFrames based on our retime output result. Set a key frame at 1001 as 1001 in input frame knob. Got...
Nuke work flow optimisation tips: Work flow optimisation is very important and help-full while you render or preview the shot. When you working with bigger shots you should optimise your script for better working speed and rendering. Otherwise you always suffer lot with your machine.... God damn in slow ???!!!!! Here i'm going to give you guys some off my own way off working style and work flow optimisation tips.... Hope this will help you guys.... at-least... First thing first. 1. Avoid multiple read nodes. 2. Keep adding(over) your FG layers always on "A" input and keep connect BG to "B" input. Working like this way will help to keep track your "BoundingBox" size. Have a habit to always set your bbox to "B" from "union" after adding every Merge. i personally use to do this when ever add "Merge" node ( in some case you need keep it union, like.... BG replace, match-moving ) If you forge...
chromatic aberration Most people doesn’t understand What is "chromatic aberration"and struggle to handle it on post production. Here is simple solution to understand and produce good result in post. First is first.. What is chromatic aberration? Chromatic Aberration, also known as “color fringing” or “purple fringing”, is a common optical problem that occurs when a lens is either unable to bring all wavelengths of color to the same focal plane, and/or when wavelengths of color are focused at different positions in the focal plane. for more info: http://toothwalker.org/optics/chromatic.html Look below image Right side. You can see the red color (fringing) bleeds on the object edges.Its because of chromatic aberration. How its happen? Chromatic aberration is caused by lens dispersion, with different colors of light travelling at different speeds while passing through a lens. As a result, the image can look blurred or noticeable colore...
