. ▁ ▁Data ▁rate ▁ ▁DVD - Video ▁disc s ▁have ▁a ▁raw ▁bit rate ▁of ▁ 1 1 . 0 8 ▁M bit / s , ▁with ▁a ▁ 1 . 0 ▁M bit / s ▁overhead , ▁leaving ▁a ▁payload ▁bit rate ▁of ▁ 1 0 . 0 8 ▁M bit / s . ▁Of ▁this , ▁up ▁to ▁ 3 . 3 6 ▁M bit / s ▁can ▁be ▁used ▁for ▁subt it les , ▁a ▁maximum ▁of ▁ 1 0 . 0 8 ▁M bit / s ▁can ▁be ▁split ▁amongst ▁audio ▁and ▁video , ▁and ▁a ▁maximum ▁of ▁ 9 . 8 0 ▁M bit / s ▁can ▁be ▁used ▁for ▁video ▁alone . ▁In ▁the ▁case ▁of ▁multiple ▁angles ▁the ▁data ▁is ▁stored ▁inter le aved , ▁and ▁so ▁there ▁is ▁a ▁bit rate ▁penalty ▁leading ▁to ▁a ▁max ▁bit rate ▁of ▁ 8 ▁M bit / s ▁per ▁angle ▁to ▁compens ate ▁for ▁additional ▁seek ▁time . ▁This ▁limit ▁is ▁not ▁cum ulative , ▁so ▁each ▁additional ▁angle ▁can ▁still ▁have ▁up ▁to ▁ 8 ▁M bit / s ▁of ▁bit rate ▁available . ▁ ▁Prof ession ally ▁encoded ▁videos ▁average ▁a ▁bit rate ▁of ▁ 4 – 5 ▁M bit / s ▁with ▁a ▁maximum ▁of ▁ 7 – 8 ▁M bit / s ▁in ▁high - action ▁scenes . ▁Enc oding ▁at ▁less ▁than ▁the ▁max ▁bit rate ▁( like ▁this ) ▁is ▁typically ▁done ▁to ▁allow ▁greater ▁compatibility ▁among ▁players , ▁and ▁to
