Nadjoua Bansil and Linda Bansil, filmakers, were released after spending eight months in captivity.
The pair were kidnapped in Sulu in the Philippines in June 2013.
While the Philippine National Police said that the sisters escaped from their captors, sources told GMA News that ransom negotiations had likely yielded the release.
The pair were kidnapped after going to Jolo to shoot a documentary about improverished coffee farmers.
Arrangements made with local Moro networks for safety apparently broke down.
Most of the sisters films have been about Muslim life.
Police believe the Abu Sayyaf Group group was behind the kidnapping.
Sources said the kidnappers wanted a P50 million ransom but that it was bargained down.
