Hopefully, this article has helped you navigate them just a little bit better. Because of this, any step in the chain—raw, LogC video or standard video—can be recorded. In This Article: Raw data is usually at high bit depth, between 12- and 16-bit, but video is usually around 8- or 10-bit. A deposit reserves this item and will be applied to the final purchase price. Justine a young vegetarian goes to study at a remote vet school. Raw is getting everything the sensor has to offer; likewise, Log curves are designed to get the most tonal range out of the sensor. Simply put, it's just sensor data before any image processing. The RED cameras shoot in REDCODE, which has compression options from 3:1 to 18:1. 'Raw' turns a cannibal coming-of-age story into a shocking, clever feminist parable – our review on what may be the best horror movie of the decade. There’s a hallucinogenic quality to the deadpan scenes of Justine coming to grips with this personal channeling of passion and perversity, and a shocking aspect to the carnage that feels invasive in a way most shock artists can’t conjure. One of the more common questions I’m asked is, “What’s the difference between uncompressed video, raw and Log recording?” With so many cameras these days offering different recording options, combined with the popularity of external recorders, it’s no wonder there are a lot of questions about this topic. Each is designed for a specific camera, but all have a similar result. The answer is still "yes and no." While they’re very different formats, they have the same general application. Understanding Look Up Tables (LUTs) – An explanation of the settings used to accurately perform color grading on digital video footage. These are both forms of compression that happen in the camera, even before recording. Raw data is usually at high bit depth, between 12- and 16-bit, but video is usually around 8- or 10-bit. So what about uncompressed video? At AbelCine, we offer a class on video formats that covers a variety of different terms and compression formats. RAW photography editing basics. The ALEXA converts its Raw data into LogC video; this information can be recorded or sent out over HD-SDI. This would be the closest thing to a true uncompressed signal. None of which should suggest that Raw is simply a grad-school term paper smothered in gore. Is HD-SDI not uncompressed then? A standard for HD-SDI output on a professional camera is considered to be uncompressed; however, the specification for a single HD-SDI output in a 1920×1080 resolution is 10-bit 4:2:2. Want more Rolling Stone? Definition of The movie is raw raw means unaltered from its original form raw = original bitrate, quality, size For foreign film, it means untranslated Therefore, we can call it uncompressed 10-bit 4:2:2 video—sounds better than color and bit subsampled video, doesn’t it? The sensor information is always gathered before converting to a video output, but not all cameras let you record or output that data. Fantasy Made From Dahl Parts, ‘Letter to You’ Review: Bruce Springsteen’s Long, Loving Look Back, ‘Martin Eden’: A Young Man’s Literary Journey, A Cinematic Knockout. We want to hear from you! The cameras from RED record exclusively Raw data. The idea of Log recording came about with Kodak’s Cineon system for scanning film. The color pattern of the photosites most often used is the Bayer pattern, invented by Dr. Bryce E. Bayer at Kodak. This means that Raw isn't video. The ALEXA can output uncompressed video over its HD-SDI outputs, either in 10-bit 4:2:2 (over Single-Link HD-SDI) or 10-bit 4:4:4 (over Dual-Link HD-SDI). Ducournau has referred to her movie as a coming-of-age story, and you can see this waifish character go from awkwardly tottering in high heels (a shot that spells out the movie’s ideas on femininity drag; don’t even ask about the Brazilian waxing sequence) to aggressively asserting herself over 99 blood-flecked minutes. Keep up to date with all our latest news! Every camera has a “raw” step in the image-capturing process. So what is raw anyway? Oddly enough, the camera can record in 12-bit 4:4:4 ProRes internally, but a standard HD-SDI only supports 10-bit. 709) HD video. As we said before, video is derived from Raw data off a masked single sensor, or something like a 3-CCD imaging block, and usually something is lost along the way. The idea of raw recording for motion pictures wasn’t popular until the release of the RED ONE camera many years ago. Sony calls their map S-Log, Canon's is Canon Log, and ARRI's is LogC. Log isn't Raw; it's video. Sony, Canon and ARRI have all taken the idea of Log film scanning and applied it to their sensors. Simply put, it’s just sensor data before any image processing.

One of the more common questions I'm asked is, "What's the difference between uncompressed video, Raw, and Log recording?" Oddly enough, the camera can record in 12-bit 4:4:4 ProRes internally, but a standard HD-SDI only supports 10-bit. Raw recording is very different than Log, but they have similar applications. Both ARRI and DALSA had cameras that could output Raw sensor data. To really answer the question, and to understand the difference between all of these formats, we need a little bit of background. Then an accident causes her sister to lose a digit. This maximized the information from the film that could be stored in the video format. Log isn’t raw; it’s video. Sony's new F65 can record in Raw or HD video, and the ARRI ALEXA can output Raw data over an SDI connection, while recording video internally at the same time. However, it's a special way of capturing that maximizes the tonal range of a sensor. The Rules of LOG exposures — How to meter and capture footage when shooting in LOG for the maximum tonal and dynamic range. In RGB (4:4:4) video, each pixel contains color and brightness information, which would be rather large with 16-bit depth. Likewise, Sony’s F65 has 3:1 and 6:1 compression options in F65RAW mode. Both raw and Log can be uncompressed, but that depends on the recording device. Both ARRI and DALSA had cameras that could output Raw sensor data. How it shows up in the finished video output can be hard to detect, and the less compressed options in both of these cameras are often considered fairly lossless (limited quality loss). Because Log is a video image, manipulations like white balance and ISO are baked in. While waiting for the paramedics, Justine impulsively explores the notion of literal finger food. A RAW file contains all the information recorded by the camera sensor for any given shot, which means it can be processed to pull out details in your photos that may be lost with other formats. So, video is generally reduced in bit depth. These terms, and many others, have all become part of our vocabulary in this digital cinema world. RED brought the idea of raw recording to the masses, though they weren’t the first. Achieving a smooth, high-quality edit viewing experience for clients, Interacting with clients during the edit process. Raw film explained WTF: Raw (2017) Posted on June 18, 2017 October 28, 2017 by Saint Pauly. How it shows up in the finished video output can be hard to detect, and the less compressed options in both of these cameras are often considered fairly lossless (limited quality loss). Flesh of any kind is initially carne non grata for Marillier’s Justine, a college student who comes from a long line of militant vegetarians; Mom freaks out when a morsel of beef makes its way into some mashed potatoes. The raw data is compressed in much the same ways that traditional video is compressed, and the process does have some effect on image quality. College is when you try on numerous identities and experiment with new ideas before your in-flux personality calcifies into an adult-shaped mold – so, the film suggests tongue-in-chomped-cheek, why wouldn’t anthropophagy be on the docket as well? Additionally, color information is generally reduced as well, from 4:4:4 to 4:2:2. This, along with a high bit rate, allows for a huge amount of adjustment in post. These cameras are converting the Raw data into video for monitoring; the ALEXA adds the ability to output the Raw data at the same time.
