Overview

Logo change and subtitle

The Otso in the season title is a Filipino language rendering of the Spanish word ocho ("eight"), indicating the season number. This season saw another logo change from the previous season: an eye logo using motifs from the Philippine flag (from which producers customized the new generic eye logo of Big Brother), atop the show's title and enclosed by an outline of a house. The adaption of the new generic franchise logo is the first among all the franchises worldwide.

Timeslot

The weekday primetime program of the show aired at 10:15 p.m. on weekdays after the last primetime teleserye in the primetime program block of the network. An afternoon edition titled Pinoy Big Brother: Otso Gold aired at 5:15 p.m. after Los Bastardos.

The weekend primetime program was originally aired at 7:30 p.m. during the batch 1 teens; however, after the first season of I Can See Your Voice ended, Pinoy Big Brother: Otso moved its timeslot to 10:00 p.m. on Saturdays and 9:30 p.m. on Sundays in order to give the timeslot to World of Dance Philippines since the batch 2 adults.

House changes

This season showed a major revamp in the house layout. On September 7, 2018, Director Laurenti Dyogi made a vlog about the reconstruction of the house. The new house design was finally unveiled on November 7, 2018 during its house blessing. Several housemates from previous seasons have visited the house and have taken pictures for their social media accounts. Official house photos were released on their Facebook page on November 10, 2018. The management opened its doors to 888 visitors to tour the House for 8 minutes on November 10, 2018.

From his livestream, Dyogi has stated that the show has upgraded to using HD PTZ cameras, making Otso the first season to fully broadcast in high definition and in 16:9 aspect ratio (Lucky 7s Vietnam leg was shown in 16:9, but the show reverted to 4:3 upon the housemates' return to the Philippines). It was worth noting that the one-way mirror system, used in earlier seasons for cameramen to capture events in the house, was no longer present.
