The problem is, timecode alone, while sufficient to provide syncing points for post production, may not be a reliable way to keep devices in sync with each other. With timecode, unless the cameras or recorders are re-jam-synced frequently, their timecode will start to drift apart. The problem is that the quartz crystal (or other piezo-electric material) clocks used in many cameras and quite a few audio recorders are too imprecise for critical applications.
Roller Naps. Paint roller nap sizes range from 1/4 to 1/2 inches in length. When painting a ceiling, the selection of a roller nap size depends on the surface of the ceiling. In general, a ceiling with a matte, flat, or eggshell finish calls for a roller nap of between 3/8 and 5/16 inches. If the ceiling is more textured, however, a longer nap may be called for.
