Hi Terry,
If that product is based on the work of Levin, Lischinski, and Weiss at the Hebrew University in Jerusalem, it might do the job well.
To correct what llamalord said earlier, Technicolor did not do the bulk of the colorization of old movies. That was done by a firm in Marina del Rey, that I believe went bankrupt and is reincarnated as Legend Films.
Technicolor, for decades, has been primarily a lab engaged in making release prints using the same integral tri-pak material as other labs like Deluxe and CFI.
Although Herbert Kalmus—founder—pioneered the three-strip camera and the dye imbibition process in the 30s, Technicolor had abandoned those technologies by the time I worked for them—computerizing the color timing operation.
The cinema colorization began with digitizing the B&W film with as many gray-scale values as possible. In principal, colors could be assigned to each level in the various regions in a frame, and computer programs could track those colors through subsequent frames. Much hands-on guidance was required.
Although labor intensive, the majority of the approximately 150 people involved were engaged in such activities as researching the colors to be used and story-boarding them.
The computer-generated production then went through a color-timing process similar to what Technicolor did for TV productions.
Regards,
Marty
