The festival announced in May that it was being pushed back from July to September, but hadn't decided the exact dates. The new timing overlaps with the Thailand Entertainment Expo, which kicks off on September 24 and combines film, TV, music and animation-related events.
The Federation of National Film Association of Thailand and Thai Directors' Association are the main organisers of the festival, replacing the Tourism Authority of Thailand (TAT), whose previous governor was implicated in a corruption scandal relating to the BKIFF.
TAT is still partially funding the event, which has a hugely reduced budget, along with new partners and sponsors including the Ministry of Culture.
Yongyooth Thongkongtoon, president of the Thai Directors' Association, said the festival would focus on Asian content.
