The footage probably looked spectacular on the IMAX screen, but it does not translate that well to regular television screens. IMAX screens are very large and purposefully curved. Showing the curved image on a flat-screen television creates a disorienting fisheye look. The HD presentation on Blu-ray is a much better representation of the film, as far as picture quality, than DVD on a standard television. The video is presented in widescreen 1080p HD 1.78:1 aspect ratio. The picture looks very good. It is not as spectacular as it could be, but considering the source material is twenty years old it is certainly acceptable. The picture is clear and sharp. The sound is presented in DTS HD Master Audio 5.1 Surround. The sounds are crisp and the narration is clear. Given this is a documentary there is not a lot of dynamics, but there is full bass resonance during the volcanic eruptions. The sole special feature is trailers for other IMAX movies available on Blu-ray.
