Parsons, Kansas, by the sole remaining lab capable of processing it. In December 2012, Kodak discontinued color reversal stock in all formats, including 35 mm and Super 8. However, in Spring of 2019, Kodak introduced Ektachrome 100D in super 8 and 16 mm formats, citing surges in demand. Today there is still a variety of Super 8 film stocks. Kodak sells one Super 8 color reversal stock, Ektachrome 100D, and three Super 8 color negative stocks cut from their Vision 3 film series, ISO 50, ISO 200 and ISO 500, which can be used in very low light. Kodak reformulated the emulsions for the B&W reversal stocks and made Tri-X (ISO 200). Film cut to Super 8 from other manufactured raw stock such as Fuji, Orwo, Adox, Agfa and Foma are also available. Pro8mm offers 7 color negative stocks made from Kodak and Fuji film. Color Reversal film for Super 8 is still available from several Super 8 specialty companies. Wittner Kinotechnik offers Super 8 made from a batch of Agfa Aviphot 200D, which is perforated and slit for Super 8, 8 mm and 16 mm formats. This film is loaded into Super 8 and Single cartridges by several of the specialty companies. Other stocks, such as the new Fuji reversal film, and existing supplies of Kodak 35 mm 100D are often made available in Super 8 by these specialty companies. The growing popularity and availability of non-linear editing systems has allowed film-makers and any user of film to shoot Super 8 film but edit in digital. This avoids much of the tedium of handling film and the damage to the film, which can occur when editing the actual film. Super 8 films may be transferred (scanned) to digital through a variety of processes, and then imported into computer-based editing and correction systems for post production. Today's systems can even scan Super 8 to 4K digital in a variety of formats. Fujifilm Single-8 system Fujifilm of Japan developed an alternative format called Single-8, which was released in 1965 as a different option to the Kodak Super 8 format. Single-8 cartridges, without a press plate, are of a different design from a Super 8 cartridge, resembling a cassette-style design (supply and take-up reels side by side) as opposed to Super 8's coaxial cartridge design (one reel on top of the other). Therefore, Single-8 film cartridges can only be used in Single-8
