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.

All projects are proxy capable, in that they support on demand proxies. At any point, for any media, you can generate proxies. Hence, there is no option to enable or disable proxy generation. You do, however, have proxy management options to specify how and when proxies are generated for clips used in the project.

For more information on On Demand Proxies, see: Working with On Demand Proxies.

Set proxy management options:

  1. If you want proxy generation to be the default option in your project, enable the Generate Proxies as Default button.
    Note: You can generate proxies on demand for any media in your project at any time, even if this button is not enabled. This simply makes it the default option at project creation.
  2. 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. Set the minimal width criteria for generating proxies by entering a value in the Conditional Proxy Width field. For example, enter 1280 to generate proxies only for clips with a width of 1280 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.
