Proxy Scaling

Proxy scaling reduces the resolution when loading files to allow more images to be stored in the memory cache at the expense of image quality. Proxy scaling can also improve playback speed since the images are smaller.

The proxy scale may be set from the file menu or file preferences.

8-Bit Conversion

This option converts images to 8-bits when loading files to allow more images to be stored in the memory cache at the expense of image quality.

8-bit conversion may be set from the file menu or file preferences.

Memory Cache

The memory cache allows the application to store images in memory which can improve playback performance. When the memory cache is disabled the images are streamed directly from disk.

The memory cache may be enabled or disabled from the file menu or file preferences. The size of the cache is set in the file preferences. The size should be set large enough to hold your image sequences and smaller than the amount of memory in your computer.

The cached images are shown in the playback bar and the state of the memory cache is shown in the information bar.
