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.
Once youâre done going around the length of the ceiling, brush around any light fixtures or anything else on the ceiling. Again, just paint about 4 inches out and donât leave any start or stop marks with the brush. Now itâs time to roll. Youâll need a roller cover on a roller handle. Youâll also want a stout extendable roller pole. A 1/2-inch roller cover will work on most textured ceilings, but popcorn ceilings are far easier if you use a 1 1/4-inch cover.
