Per-object settings and performance

Use per-object export settings wisely. Per-object settings let you fine-tune an exported SWF file by letting you specify the best format for objects that are converted to bitmaps when exported, reduce colors, experiment with different levels of quality, and so on to find the best balance between output quality and file size. However, LiveMotion has to store and track each setting, which can increase memory use and decrease performance. It's a good idea, therefore, to pick the setting that works best for most objects and store it at the document setting (this is what you're doing when you specify settings without selecting Object in the Export palette and making a new setting). Also, use Preview Export Compression to check whether an object becomes a bitmap when exported. If it doesn't, there's no reason to add a per-object setting to it.
