(written from a Production point of view)
POP Film & POP Animation, formerly known as Pacific Ocean Post Digital Film Group or simply Pacific Digital Post, was a post production company which provided digital effects for various Star Trek productions.
POP was founded in 1994 as a subsidiary division of Four Media Company (and was therefore a sister company of Digital Magic ), and became associated with Star Trek the following year when they provided digital optical effects for the Star Trek: Voyager episode "Learning Curve". They then provided video optical effects shots for the Voyager episode "Projections", "Elogium", and "The 37's" and the Star Trek: Deep Space Nine episode "Facets" before becoming Deep Space Nine's primary digital effects producer until the end of the show's fifth season.
Credited as Pacific Ocean Post Digital Film Group, the company provided the digital effects for Star Trek: First Contact, under the supervision of Scott Rader and Adam Howard and produced by Andrea D'Amico. Finally, as POP Film & POP Animation, they produced visual effects for Star Trek: Insurrection. David Sosalla was POP's Visual Effects Supervisor on Insurrection; Melissa Brockman was the company's Visual Effects Producer.
POP has worked on many other projects, including the films Tank Girl (starring Lori Petty, Malcolm McDowell, Jeff Kober, Reg E. Cathey, Ann Cusack, and Iggy Pop), Batman Forever (featuring Rene Auberjonois and John Glover), Titanic (featuring David Warner), Flubber (featuring Clancy Brown and Wil Wheaton), The X-Files (featuring John Neville and Terry O'Quinn), Payback (starring Gregg Henry and John Glover), Fight Club (featuring Zach Grenier and David Andrews), and X-Men (starring Patrick Stewart, Famke Janssen, and Bruce Davison and directed by Bryan Singer). In addition, besides Star Trek: First Contact and Star Trek: Insurrection, POP has provided effects for two other films featuring Brent Spiner: the 1996 science fiction blockbuster Independence Day and the 1997 romantic comedy Out to Sea.
POP ceased its digital effects and animation work in the early 2000s. They currently operate as POP Sound, providing sound mixing and editing services for film, television, and the music industry.
