## LINK TOOLS
	Utility functions for creating linked nodes. This script can create roto linked to trackers, 
	transform linked to trackers, or cameras linked to each other, or held on a projection frame. 

Installation:
Put link_tools.py somewhere in your nuke path.
You can add the script as commands to your Nodes panel. This code creates a custom menu entry called "Scripts".

Enable DNG Support for Your Camera in Corel AfterShot Pro 3

AfterShot 3 does not support DNG files well, despite their claims to the contrary.

What if we need to use DNG files in our photo collection? There are valid reasons to need this, for example if you use Magic Lantern Dualiso raw files on your Canon camera and you need to use the DNG format to store the raw image after blending the exposures.

AfterShot does open DNG files if certain conditions are met. If you have specific supported cameras, AfterShot will open DNG files, but only if it has the right compression settings and metadata. The DNG file has to be uncompressed, and it must contain the Exif.Image.Model metadata matching a "known" camera.

Hack Your Own Camera Profile

1. On the Aftershot Downloads Page there are AfterShot Pro Camera Profiles available for download.

Retime Roto

This is a python script for Nuke to retime roto shapes. It supports shapes only, not strokes, not opensplines.

It works by looping through each roto node, each shape in the roto node, and each point on the shape. It creates an expression on each point referencing a frame_lookup knob. Put a retime curve on this knob and your shapes will be retimed.
