Proxy Settings

Proxies are low-resolution copies of high-resolution clips. Using proxies increases playback performance, especially when working with large files.

At any point, for any media, proxies can be generated. Hence, there is no option to enable or disable proxy generation. Proxy settings specify how and when proxies are generated for clips used in the project.

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

Generate Proxies By Default

All projects are proxy-capable, in that they support proxies on demand. Enable the Generate Proxies By Default button to make proxy generation the default behavior at project creation.

Proxy Ratio

Set the fraction for resizing the proxy image. Alternatively, you can select Custom and manually set the size of the proxies as a percentage value, using the slider that appears below. Proxies maintain the same aspect ratio as their sources.

Proxy Quality

Set the quality of the proxy image. Proxy quality affects rendering and proxy generation duration since lower qualities are faster to calculate. However, the quality does not affect the amount of storage space required.

Conditional Proxy Width

Enter a clip width for conditional proxy generation, in pixels. Proxies will be generated for all clips having a width greater than this value. You can also drag on the field to modify it. Editable.

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.
