Proxies are low-resolution copies of high-resolution images, one for each frame. Set proxy management options to specify how and when proxies are generated for clips used in the project.

To set proxy management options:

1. From the Proxy Management option box, select an option.
   TipTo change proxy management options for a current project, you must access the Project Management menu from the Preferences menu.

   
   

   Select:	To store:
   Proxies Off	No proxies, no matter what resolution clips you work with.
   Proxies On	Proxies for all clips larger than the proxy width you set for all proxies.
   Conditional	Proxies only for clips that meet conditional criteria, for example, clips that exceed a width of 1000 pixels.

2. If you selected Proxies On or Conditional, specify the proxy size by doing one of the following:
   • Select Fixed Width from the Proxy Size box and then enter a value in the Proxy Width field beside the Proxy Size box. For example, enter 720 to create and store proxies 720 pixels wide. Proxy height is determined by the clip's aspect ratio, relative to the proxy width that you set.

   
   

   TipWhen the proxy and full resolution clip have the same bit depth, proxies are not stored for clips that are the same width as the proxy width. For example, if you set proxy width to 720, your project will not store proxies for NTSC clips (720x486). If the bit depth of the full resolution clip is greater than that of the proxy, proxies are stored for clips with the same width as the proxy.
   • Select Frame Percentage from the Proxy Size box and then enter a value in the Scale field. For example, enter 0.50 to create and store proxies that are 50% of the clip resolution.

   
   

   Proxies always have the same aspect ratio as the full-resolution clip. The width of proxies for clips with the default resolution corresponding to the scale value you set is displayed in the Width field.

3. If you selected Proxies Conditional, set your conditional criteria.

   
   

   • To store proxies for all clips of a certain width and greater, enable Frame Width > and then enter a value in the adjacent field. For example, enter 1000 to store proxies for all clips wider than 1000 pixels.
   • To store proxies only for 10-bit, 12-bit, or 12-bit unpacked clips, enable Depth > 8-bit.
   NoteThese two settings are not mutually exclusive. For example, if you enter a value of 1000 in the Frame Width field and enable Depth > 8-bit, a 12-bit clip with a width of 720 will get proxies as long as the project proxy width is less than 720.
4. From the Proxy Quality box, set the quality of the proxy image for viewing purposes.

   
   

   Proxy quality affects processing and proxy generation duration since lower qualities are faster to calculate. However, the quality does not affect the amount of framestore space required for proxies.

   Select:	To specify:
   Draft	The lowest possible quality. This is the quality used when proxies are generated automatically following video I/O.
   Coarse	The next highest quality after Draft.
   Medium	The next highest quality after Coarse.
   Quality	The next highest quality after Medium.
   Bicubic	The highest possible quality.

5. From the Proxy Bit Depth box, select the bit depth for proxies.

   
   

   Select:	To set:
   Depth: 8-bit	The proxy bit depth to 8 bits.
   Depth: Full Res	The proxy bit depth to be the same bit depth as that of the clip.
