That sound of string is more similar to east:
listen the strings in the minute: 1:42 to the 1:47... And in the minute 2:19 from now on

 

Spitfire Audio LLP Solo Strings would work nicely. (but there's also plenty of more libraries to work too)

 

Hmm it sounds more like chamber section than solo, in that case, Sable is the option *yes*

 

Actually, you can make LLP Solo Strings sounds like the top strings of that mentioned region of the song, because i loaded up Kontakt myself when i saw his question and played myself that part on my keyboard and i heard it sounding similar. Yea', Sable is a option too, beying capable to cover EVERYTHING in that region but i think is a overkill for his needs, because this library is capable for alot more than Solo Strings, but it's also alot way bigger and he probably won't fully use it, but i must admit that it's a top notch strings solution.

P.S. I also saw that girl violonist in the music video and i thought he's referring on the solo side of the strings.

 

It wanted to know which of all the 3 volumes of sable:
BML SABLE VOL 1?
BML SABLE VOL 2?
BML SABLE VOL 3?

 

Just first volume, that contains Violin:
BML SABLE VOL 1
