Hi, Randy and Michael, I guess 6K is enough resolution, but the TIFs I have of each 35 mm slide are approx 36 MB each. 3000 x 4500 (minus some cropping) pixels @ 3000 ppi. You can't put too many of those into FCP, can you? They certainly crashed Premiere a while ago. Also, as a side note, top-quality Kodachrome and Fuji Velvia 35 mm slides are more faithfully captured at 4000 x 6000 pixels, 16 bits/colour, making approximately 144 MB TIF files per image. Frankly, very few of the images I'm scanning can truly benefit from this increased scan detail, but some can. It seems that audio-visual materials are held in sound archives. I have transferred a few cassette tapes with simple "beep" tones on track 4. The issue with resolution is that if each slide can benefit from 3000 x 4500 pixel scans, and you've got a 4x4 grid you need 6000 x 9000 so as to not lose resolution, or in the 3-wide display, 3000 x 13,500 and that does not take into account vertical images. I realize we did not achieve that resolution with typical Kodak Carousel zoom lenses, even with autofocus. Ingesting the elements is not a challenge, but having attempted it at high resolution a while ago, assembly IS a challenge. Retaining the IMPACT of the original show is the challenge. Reference copies are not a challenge (though still tedious). As to Mike Biel's point, the cue tracks that he describe were, I believe, proprietary formats per manufacturer. AVL was the name that came to mind, but they are now gone. At one point, their controllers would record all the cues on the audio tape. The later units, described here from http://en.wikipedia.org/wiki/Eagle_Computer , merely had a time code track on the tape. <quote> The first Eagle computers were produced by Audio Visual Labs (AVL <http://en.wikipedia.org/wiki/AVL>), a company founded by Chuck Kappenman in New Jersey in the early 1970s to produce proprietary large-formatmulti-image <http://en.wikipedia.org/wiki/Multimedia#History_of_the_term>equipment. Kappenman introduced the world's first microprocessor-controlled multi-image programming computers, the ShowPro III and V, which were dedicated controllers. In 1980, AVL introduced the first non-dedicated controller, the Eagle. This first Eagle computer utilized a 16 kHz processor and had a 5¼-inch disk drive for online storage. The Eagle ran PROCALL (/PRO/grammable/C/omputer/A/udio-visual/L/anguage/L/ibrary) software for writing cues to control up to 30Ektagraphic projectors <http://en.wikipedia.org/wiki/Carousel_slide_projector>, five16 mm film <http://en.wikipedia.org/wiki/16_mm_film>projectors and 20 auxiliary control points. Digital control data was sourced via anRCA <http://en.wikipedia.org/wiki/RCA>orXLR <http://en.wikipedia.org/wiki/XLR>-type audio connector at the rear of the unit. AVL's proprietary "ClockTrak" (a biphase digitaltimecode <http://en.wikipedia.org/wiki/Timecode>similar to, but incompatible withSMPTE <http://en.wikipedia.org/wiki/SMPTE>timecode) was sourced from the control channel of amultitrack <http://en.wikipedia.org/wiki/Multitrack_recording>analog audio tape deck. The timed list of events in the Eagle was synchronized to the ClockTrak. Later versions of PROCALL included the option of using SMPTE timecode. Most programmers abandoned ClockTrak for SMPTE, as more multi-image programs began to incorporatevideo <http://en.wikipedia.org/wiki/Video>.^ <http://en.wikipedia.org/wiki/Eagle_Computer#cite_note-0> Two separate digital data streams were output from the Eagle, also via RCA or XLR-type audio connectors. These telemetry streams, called "PosiTrak", each controlled up to five external slide projector control devices also manufactured by AVL, known as "Doves". The Dove units received biphase data from the Eagle via audio cables, and interpreted the Eagle's data streams to control as many as threeKodak Ektagraphic projectors <http://slideprojector.kodak.com/ektagraphic/a.shtml>(for large screens, compatibleXenon <http://en.wikipedia.org/wiki/Xenon_arc_lamp>-lamped projectors) and two dry-closure contacts per Dove unit. AVL also made the Raven, a device similar to the Dove, for comprehensive control of a single 16 mm film projector, as well as numerous other external control devices for lighting, sound, video projectors and sources, etc. AVL Eagles and associated products, when properly setup and powered, were extremely reliable. During the 1970s through the early 1990s, when the products of its competitors were not as reliable nor readily available, AVL became the industry standard for multi-image control equipment. However, the development of large-screen electronic media andHDTV <http://en.wikipedia.org/wiki/HDTV>ushered out the era of film-based multi-image productions.^ <http://en.wikipedia.org/wiki/Eagle_Computer#cite_note-1> </quote> The first footnoted link is: http://www.honda600coupe.com/random/AVL/index.html The second one is 404 gone, like the technology, but the text (but sadly not the images) is available here http://web.archive.org/web/20100113083108/http://www.avsquad.com/page8/page8.html Cheers, Richard -- Richard L.
