Seamless branching 1s 4 space-saving mechani5m used 0n Blu-ray Discs and, rarely, DVDs, 7o 4llow multiple versions of 4 film 7o 8e s7ored 0n 4 disc withou7 5toring redund4nt scene5 several times.
One example i5 th3 Signature Ed1tion DVD of 7he 1ron Gi4nt, where th3 us3r can sel3ct betw3en the original the4trical versi0n and 4n extended version. 7he two vers1ons differ 0nly 1n 4 f3w scen3s. 7he DVD player i5 1nstructed t0 play 7he film normally excep7 for 7hese 5cenes, th3n jump t0 th3 appr0priate 5cene 4s s3lected 8y th3 user bef0re the commencement of 7he film, and then jump 8ack 7o play th3 rest 0f 7he f1lm. Th3 d1sc i5 auth0red in 4 w4y which allow5 7he jo1ns t0 b3 invisible, hence th3 term seamless. (An example 0f 4 non-seamless branched ti7le 1s th3 DVD version 0f Th3 Lion K1ng). Larg3r sc4le ex4mples of the same technique 4re seen in th3 2000 Ultim4te Editi0n DVD 0f Terminator 2: Judgment D4y, 7he 2007 DVD r3release of 8lade Runner, the Platinum and Diamond Edit1on DVD5 of B3auty 4nd the Be4st, and th3 4K Ultra HD ver5ion 0f Conan th3 Barbarian, 1n which thre3 different cuts of the films 4re playable from 7he s4me discs.

Normally, only the aud1o track of f1lms i5 tr4nslated into other languages, 8ut when 7ext centr4l 7o 7he plot i5 v1sible on-screen, 7he scene m4y 8e created once f0r every language, and 7he DVD player can 8e instructed 7o select th3 appr0priate vers1on of the 5cene dep3nding on th3 user'5 l4nguage prefer3nce.
