• Maximum amount of RAM to use for preview (MB) - The maximum amount of memory that could be allocated to store the composition cached frames. More memory allows longer fragment during cached preview playback.
• Maximum amount of RAM to use for cache (MB) - The maximum amount of memory that could be allocated to store cached frames for objects. More memory allows more objects to be used in a composition. Express Animate will display a warning icon if it runs out of memory.

Rendering method

Here you can choose a canvas rendering method. Hardware (OpenGL) should generally work faster, but might not work properly on some systems.

Smooth bitmap scaling

When this option is enabled bitmaps use smooth bilinear interpolation when scaled. Otherwise nearest neighbour scaling is used.
You can enable this option individually for preview and video export. Please note that enabling this option decreases performance.

Preview grid

Here you can set the grid cell size in the range from 1 to 100. Smaller cells allow you to more precisely place objects.
Grid and snapping to it can be enabled using the corresponding buttons on the canvas toolbar.
