Chapter 4 Using Proxies 155
Anamorphic Images and Pre-Generated Proxies
Do not use the proxyRatio parameter to change your aspect ratio on the fly if working
with pre-rendered proxies. This parameter dictates the relationship of the height-to-
width ratio between the proxy file and the base file as they exist on disk. Therefore,
either ensure you are using flattened pre-generated proxies (that can be a second
proxy set), or use the global parameter viewerAspectRatio to flatten the anamorphic
proxies. In the following example, image A is the full-resolution anamorphic frame, so it
looks squeezed. Image B is a half-size anamorphic-resolution proxy. Image C is a half-
size, flattened image. This is how the raw images appear on disk.
Therefore, your proxy settings should be:
• P1: Image B, scale of .5, ratio of 1; as the ratio of the height to the width is the same
as in image A.
• P2: Image C, scale of .5, ratio of .5. The width is the same as image B, the ratio is half
of the ratio of the height-to-width of image A.
How Proxy Paths Are Defined
The default paths for proxies generated by Shake use variables that reference the name
and format of the original source media files. If the proxySet pop-up menu is set to
Relative, then the path of the proxy1DefaultFile is:
../proxy.50/<base>.<format>
This path translates into the following:
• ../ references the directory level of the directory containing the original media files.
• <base> represents the image name and the frame range of the original media files.
• <format> represents the format extension of the original media files.
Therefore, if the original media files being referenced are named MyAmazingFootage.1-
100#.cin:
• <image name> = MyAmazingFootage
• <frame range> = 1-100#
• <base> = MyAmazingFootage.1-100#
• <format> = cin
