Alright, so here we are, one of the elephants.

2
00:00:05,000 --> 00:00:13,000
The cool thing about these guys is that they have really, really, really long trunks.

3
00:00:13,000 --> 00:00:16,000
And that's cool.

4
00:00:16,000 --> 00:00:19,000
And that's pretty much all there is to say.

Then:

$ subt 'Me at the zoo [jNQXAC9IVRw].srt' -d ja
Saved: './Me at the zoo [jNQXAC9IVRw].translated.srt'
$ cat 'Me at the zoo [jNQXAC9IVRw].translated.srt'

00:00:00,000 --> 00:00:05,000
さて、ここに私たちは象の一人です。

2
00:00:05,000 --> 00:00:13,000
これらの人のクールなことは、彼らが本当に、本当に、本当に長い幹を持っているということです。

3
00:00:13,000 --> 00:00:16,000
そして、それはクールです。

4
00:00:16,000 --> 00:00:19,000
そして、それはほとんどすべてです。
