Glossary B

Backtiming	Working out where to start by working backwards from the end. (e.g. if you want a line of narration to end at a particular point, start reading as you run backwards from that point and make a note of where you stop reading - that's your start point).
	I used to work in a dubbing theatre that had a record deck that ran backwards so they could 'backtime' music off vinyl.

Best - light	Better than 'one-light'? Print or TK transfer that supposedly has the optimum setting for your material, but has not been properly colour graded, scene by scene.

Bin	Now used by Avid to describe a database, in which shots, sequences etc are logged. In film cutting rooms real bins (UK) or barrels (US) are used to stop loose film spilling all over the floor. Trim bins have a bar with pins along the top to hold clips and trims. Trims from the same shot are usually held together by a rubber band.

Blacked tape	Videotape that has been recorded with time code but no picture.

Bleeping	Way of censoring unwanted swearwords etc by replacing them with a bleep sound. It produces a comic effect which may work on 'Beadles About', but isn't always desirable.
	Alternatives include drowning out with the sound of a passing car or replacing with a milder term ('frigging' for 'f***g')... or just let them swear.

Blooping	When you make a join in an optical soundtrack you get a click. To get rid of the click; 'bloop it' (paint a V shape over the join with blooping ink). To bloop an optical soundtrack negative, cut a V shaped wedge out with scissors.

Blow-up/Bump-up	Blow-ups are film enlargements from a smaller to to a larger gauge (e.g. 16mm to 35mm) Bump-ups are video copies from a low quality format to a higher (e.g. vhs to Betacam SP)

Blue Screen	Shooting a scene against a blue background, so that a moving matte is easily produced of anything in front of it. Any background you want can then be 'painted in' to the blue areas during the on-line edit. This technique is used 'live' to put weather forecasters in front of maps so you all know the sorts of things that can go wrong; blue haloes etc.
	You don't have to use 'chromakey blue', other colours can be chosen - but just make sure its different from the heroine's dress (unless you are making "The Invisible Woman")

Buzz track	See atmos.
