For those that still have doubts about the solidity of the frame rate of The Last of Us: Remastered on PS4, Sony Computer Entertainment Worldwide Studios President Shuhei Yoshida and Game Director neil Druckman had a interesting little exchange:

Yoshida:

Can I dream of 60fps?

Druckmann:

Solidly.

Druckmann also explained that his personal preference is (maybe not very surprisingly) 60 frames per second.

Since some people asked for it, we added an optional 30fps mode (gameplay & cinematics). My pref is 60fps all the way. #remastered

Speaking about the frame rate lock for cutscenes, Lead Programmer Christian Gyrling explained how it actually works:

All movies are encoded at 60 fps. If you select 30 fps we will only display every other frame.

First of all, this clears the still lingering doubt on whether cutscenes will be pre-rendered or in-engine. The mention of "encoding" definitely clarifies once and for all that they will be indeed pre-rendered.

More importantly, we learn that only the cutscenes encoded at 60 frames per second will be on the disk. Cutscenes encoded at 30 FPS won't be included (the disk is probably quite cramped already), so the game will simply skip every other frame while displaying the 60 FPS ones.
