Stones at the Max
Rolling Stones Live at the Max also known as Stones at the Max is a concert film by The Rolling Stones released in 1991. It was specially filmed in IMAX during the Urban Jungle Tour in Europe in 1990. It was one of the first attempts at presenting entertainment in the IMAX format.
Imaging fed to the jumbotrons at concerts came from bread trucks switching live feeds from an army of video cameras. Midway through post, the request came to use some of this video that had been recorded ontape in the final IMAX film. This began a crazy series of tests to improve and upres this video to be shot on IMAX neg at the lens facility in Mississauga. Test neg was processed in New York, prints made, returned to Toronto for screening at the IMAX theater at Ontario Place. After many tries, a process was created to improve imaging enough to be used. Final release included approximatelyminutes of this footage.Originally shot withIMAX cameras outfitted with the first long load film magazines, forconcerts incities. The magazines were so huge and the ballistics of the loading so unpredictable, there was no guarantee of complete coverage of any song in any single concert. Eventually trying to cut this on a flatbed proved impossible. Recently rereleased EditDroids were in Toronto on various projects and one was custom configured with the help of the folks at Lucas in Los Angeles. All 35mm twist reduction work print was reassembled in original rolls, transferred to video and recorded on oneoff laser videodiscs. The 8headed Droid could load all data bases and imaging for a single song in all concert locations. The editors could jump to any point in a song, see what was available or not then jump to the same spot in all subsequent concerts. The trick was tracing back from the Droid data through LaserDisc data through video data back to 35mm stepdown print edge code and ultimately to the original IMAX neg frame accurately to produce the neg cut list that needed to sync with the original 64 track digital recordings. ........
