Star Trek Into Darkness COMPLETE EXTRAS 2013 720p BDRip x264 AAC-Pegatoni

Edit: It seems the extras came from different sources, not all extras are from BDRip.

Video of "Aliens Encountered.mp4", "Home Of The Core.mp4", "Safety First.mp4", "The Sound Of Music.mp4" and "Unlocking The Cut.mp4" seem to be stuttering, not smooth, as if frames were missing .
I think they were recorded with a kind of screencast software or monitor or screen recorder, as you can see the player in "Home Of The Core.mp4". They have resolution of 1152x720.

Other videos seem good.
Attack on Starfleet.mp4, Creating The Red Planet.mp4, Down with the Ship.mp4, Enemy Of My Enemy.mp4, Going From Ship to Ship.mp4 and The Klingon Homeworld.mp4 have resolution 1280x720.
Going From Ship to Ship.mp4 is neither a bonus, nor an extra scene.

Brawl by the Bay.mp4 576x324; all other videos are 512x290.
Some videos might be available in better quality on YouTube and other videostreams or streaming sites.

I completely agree to what @ffilou6 said. Quality is a mixed bag. Some of the videos are from the Youtube with bad quality. Also, if you are only looking for the extras do not download the .mp4 file outside the extras folder. Although it's name incorrectly includes "COMPLETE EXTRAS" it is the movie file whose quality is not a collector's item.

Finally get to se all the extras from the movie. Got to admit, was very pissed off with the distributer for splitting the extras through different discs - WTF was the point.. Anyway, thanks to the uploader for making my day!
