I don't understand why everyone wouldn't subtitle their content. I used rev.com and it costs $1 per minute and the results are great. So to subtitle three hours cost $240. With many non-native English speakers as customers it is a no-brainer.
It's good to hear this too, because the text in that box originally said 'Filmed in 4K' and I only changed it to 'Fully subtitled' at the last moment.
