We always use white, or clear leaders with image markings and a blackened sound track for commercial reels and features. At the end of the leader, there are 2.5 metres of black material with the start foil for the automation and then the sound trailer. The leaders are measured exactly and pre-assembled so that they work on each screen regardless of how long the film path from platter to projector and back is. So we don`t have to change them when we move a print between screens. When a movie leaves the cinema, we take the leader of, roll it up and put it on the shelf. The shelf has different compartments for "Leaders without sound trailer", "Leader with Dolby Canyon/WS", "Leader with SDDS Volcano/CS" etc. When we make up a print, we check the aspect ratio and sound format, then decide which leader we will use, and splice it onto the first reel. It takes about 15 seconds to do that and also conserves the sound trailers because they are not spliced/cut off all the time. The clear material is not cheap, but if you treat the leaders carefully, they will last a long time. You can always see the leader very well and with the black frame and sound track markings, it is practically impossible to thread the movie incorrectly. Old trailers are less practical and also leave more dirt in the projector as the layers start to peel of. Michael

Antonio, it is because of those unhappy moments of chaos that I have always insisted on the blank leaders. Since the commercials and the feature start with blank material, it is no problem to see where the show is should the projector be stopped or should it fail to stop after the commercials. Even in the dark booth you can always see, blank film - aha, the leader, here is the black material, aha, this is where the feature starts and so on. Once you have introduced such a system, you will never again want to wotk without it. But be careful: since the material is expensive, your leaders have to be treated very carefully. They should never be cut and always be put on the shelf when not in use or you will get confused and all the nice stuff will be gone in no time. And then go and explain to management why you wanted to buy it in the first place... Michael

"We actually use old trailers to thread a projector. But they're often confusing. We used an old part of Hannibal to thread a projector and in a moment of caos we start the show with hannibal"Yet annother pefect example of why show start queues are the desireable way to go. Clear film with framelines should be available from your supplier for a fairly low cost. I also use a bit of black leader between the framing leader and the first trailer since I too am not blessed with start queues <how simple those things make life>. The bit of old trailer at the very beginning is a great idea, as your framing leader won't get as damaged during threading, especially if you're a speed demon threading those rollers, when that part gets damaged, snip it off and replace with new old trailer material.
