Setting Proxy Management Options

Proxies are low-resolution copies of high-resolution clips. Using proxies increases playback performance and responsiveness, especially when working with large files. Set proxy management options to specify how and when proxies are generated for clips used in the project. The default setting is Proxies Off.

To set proxy management options:

1. From the Proxy Management option box, select an option.
   Tip: To change proxy management options for a current project, access the Project and User Settings dialog box.

   Select:	To display:
   Proxies Off	Full-resolution clips.
   Proxies On	Proxies for all clips
   Conditional	Proxies for clips of a specific width or greater.

2. If Proxies On or Conditional is selected, set the proxy size:
   • Select Proxy 1/2, Proxy 1/4, or Proxy 1/8 to set the fraction of resolution to be displayed by proxies.
   Note: Proxies maintain the same aspect ratio as their full-resolution sources.
3. If the Conditional option is selected, set the criteria for generating proxies by entering a value in the Conditional Proxy Width field. For example, enter 4000 to generate proxies for clips with a width of 4000 pixels or greater.
4. From the Proxy Quality box, set the viewing quality of the proxy image.

   Proxy quality affects rendering and proxy generation times. While lower qualities are faster to calculate, all proxies require the same amount of disk space for purposes of storage.

   Select:	To specify:
   Lanczos	Excellent quality, recommended for upscaling and downscaling. Slower to calculate.
   Shannon	Excellent quality, sharper than Lanczos in small details. Recommended for upscaling and downscaling. Slower to calculate.
   Gaussian	Medium quality and softer results.
   Quadratic	Medium quality and softer results.
   Bicubic	High quality, but not as sharp as Shannon. Use for both upscaling and downscaling.
   Mitchell	High quality, but not as sharp as Shannon. Use for both upscaling and downscaling.
   Triangle	Low quality, fast to calculate. Use for downscaling.
   Impulse	Very low quality, fast to calculate. Use for downscaling.
   Draft	Lowest possible quality, used when proxies are generated automatically following video I/O.

   Note: Once the Proxy options are set for a new project, they cannot be changed.
