AMP Videos

Saturday, May 19, 2012

All AMP test footage was shot in available light without the use of any artificial lighting, scrims or diffusion kits.

Videos were shot at 1080p at either 24 or 30 fps. Once captured, videos are tone mapped using a variety of available software. Videos are sized appropriately for web viewing.

Some compression effects are normal, but we have taken care to present the best videos, with the lowest buffer times.

Please be patient...

AMP Video



"amp: Getting the Whole Picture" is a brief video that shows various ways to view amp HDR footage. It's impossible to display amp HDR footage in its raw format, because today's displays (LCD screens, plasma TVs, digital projectors, etc.) do not have enough dynamic range to show all the data we capture. So we use a few different methods to show the extraordinary range of light-levels that we capture. The amp prototype camera used to capture this footage comprises three SI-1920 camera sensors, to capture high, medium, and low exposure images for each frame of video. To demonstrate the amount of dynamic range that the amp system adds to the standard SI-1920 camera, we show comparisons between the amp footage and the same footage seen with the medium-exposure SI-1920 sensor, or what a "typical" camera might see for each scene. Working together with Erik Reinhard, we have developed a new video tone map operator (TMO) to provide real-time, natural-looking output from our next-generation cameras (via HDMI). This new fully-automated video TMO, which we call the Kiser-Reinhard TMO, gets applied to both the raw SI-1920 (single sensor) videos and to the amp HDR videos. On a properly-calibrated video monitor or projector, you can see the extension of color and details, as well as the removal of significant noise, both up into the highest highlights and down into the darkest lowlights of the scenes. "A Versatile HDR Video Production System" is the technical video that accompanied our SIGGRAPH paper of the same name. The technical paper was a team effort between Contrast Optical and University of New Mexico Advanced Graphics Lab. "Melting Snow" is a video that shows raw exposure data captured with the AMP camera. Each frame of video captured by AMP is a true HDR image, which can then be tonemapped a variety of ways for display. Learn more in the Vimeo description. "AMP Digital Video" is fun video that introduces the AMP Camera Technology and gives a sneak preview of the GEN II camera features. "Again! Again!" is a brief video comparison between a typically exposed scene with a digital cinema camera and the same exact scene captured with AMP Technology. See our FAQ for more information.
