Sometimes, a friend suggests suddenly that we would take a photo. Then we have a gesture as follow :
Photo ? Why, without a reason ?
(A) 사진 ? 아 왜 갑자기 ?
When I watch a Korean drama in youtube, I can find a script :
(B) sahjhan oh I'm the cop jacket
It is weird to me. In my thought, the following is more closer :
(C) sajin ? ah why gabjaki ?
To native English speaker, which one in (B), (C) is more closer to (A) ?
Youtube's subtitling system isn't intended to add accurate Romanisations of (e.g.) Korean speech. As per gaeguri's comment, It seems in your case that you just have a Korean video that is being erroneously interpreted as English.
It is possible for youtube content creators to add translations to their videos, such that you'd see (for example) "A Photo? Why, without a reason?" in the English translation. It's also possible to perform automatic translation, and to add custom subtitles. It's only if someone has added a custom set of subtitles that you will see romanisation of Korean on youtube.
