This, along with a high bit rate, allows for a huge amount of adjustment in post. Raw film explained WTF: Raw (2017) Posted on June 18, 2017 October 28, 2017 by Saint Pauly. Sony, Canon and ARRI have all taken the idea of Log film scanning and applied it to their sensors. While they’re very different formats, they have the same general application. 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. 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. They’re very much not the same; however, they’re both designed to get the most information out of the sensor. AbelCine provides sales & support for AGITO, Motion Impossible's remote dolly. Log isn't Raw; it's video. Hopefully, this article has helped you navigate them just a little bit better. 709) HD video. This should clue you in that Log recording is just standard video recording in the sense that all pixels display color and brightness information. Let’s start with raw, which comes first for many reasons. While waiting for the paramedics, Justine impulsively explores the notion of literal finger food. Sony calls their map S-Log, Canon’s is Canon Log, and ARRI’s is LogC. In order to be viewed on any device, a RAW file needs to be processed and compressed into a more traditional image format. So what is raw anyway? A short answer is, “Well, yes and no,” which I know isn’t terribly clear. 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. Oddly enough, the camera can record in 12-bit 4:4:4 ProRes internally, but a standard HD-SDI only supports 10-bit. RED brought the idea of Raw recording to the masses, though they weren't the first. Bojangles’ Songwriter, Dead at 78, How to Watch UFC 254 Online: Live Stream Khabib vs. Gaethje on ESPN+, Tekashi 6ix9ine Transforms Into a ‘Supervillain’ in New Teaser for Showtime, ‘Rolling Stone’ Doc, Steve Perry: ‘My Heart Bleeds Daily to Be in Front of People And to Sing for Them’, ‘The Witches’ Review: A D.O.A. 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. © Copyright 1989–2020 AbelCine. RED brought the idea of Raw recording to the masses, though they weren't the first. The idea of Raw recording for motion pictures wasn't popular until the release of the RED ONE camera a few years ago. The idea of Log recording came about with Kodak’s Cineon system for scanning film. Is wireless transmission an obstacle or an effective tool for video and sound professionals? Price, images, specifications, and descriptions of items are subject to change without notice. A transform of this video data, known as a lookup table (LUT), is required for proper viewing, which makes the video look more “normal” to us. Raw is getting everything the sensor has to offer; likewise, Log curves are designed to get the most tonal range out of the sensor. So, going back to our original question, "Is shooting Log like shooting Raw?" 3D Lookup Tables – A further examination of LUTs and how they work with high-end digital cine camera. A short answer is, "Well, yes and no," which I know isn't terribly clear. A standard LUT converts the Log video to standard (Rec. This is where things get a bit trickier. Recently, I was asked if shooting Log was like shooting Raw. Horror, Toronto International Film Festival. You could say the same for her partner-in-crime Marillier, who lets viewers join her heroine’s journey of carnal knowledge through carnivorous free-fall. She is the real thing. Both ARRI and DALSA had cameras that could output raw sensor data. To say that things begin to take on an even stronger metaphorical resonance once our heroine indulges in her newfound gourmet obsession would be grossly understating the point; the fact that this coincides with Justine’s sexual awakening, made implicit via solo dress-up grinding in front of a mirror then explicit by her ecstatically biting her own arm during sex, isn’t coincidental. 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. At AbelCine, we offer a class on video formats that covers a variety of different terms and compression formats. The sensor information is always gathered before converting to a video output, but not all cameras let you record or output that data. 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 1920x1080 resolution is 10-bit 4:2:2. A transform of this video data, known as a lookup table (LUT), is required for proper viewing, which makes the video look more "normal" to us. This should clue you in that Log recording is just standard video recording in the sense that all pixels display color and brightness information. None of which should suggest that Raw is simply a grad-school term paper smothered in gore. The ALEXA converts its raw data into LogC video; this information can be recorded or sent out over HD-SDI. Each is designed for a specific camera, but all have a similar result. In a video signal that we can see on a monitor, each pixel contains full color and brightness information; video can tell each pixel on a monitor how bright to be and what color. On the other hand, ALEXA outputs uncompressed raw data, which can be recorded externally. Smelling salts are not required, but the ability to recognize a near-perfect movie when you see it most certainly is. She begins to take ownership of her body by consuming others’. Because each pixel contains only one color value, raw isn’t viewable on a monitor in any discernible way. ARRI’s ALEXA camera is unique in that it can output raw, uncompressed and record in a Log format, so I’ll use that camera as an example throughout this discussion. The new algorithm creates much smaller video file sizes than before, while retaining the amazingly higher quality video data rates and editing capabilities, of the original Uncompressed RAW video. Additionally, color information is generally reduced as well, from 4:4:4 to 4:2:2. The converting of Raw information into video can be time-consuming for post-production, though great tools are available to make it fairly painless. Recently, I was asked if shooting Log was like shooting raw. Server error. But if Raw is Raw and video is video, then what the heck is Log recording? Recently, I wrote an article for ProductionHub's new, Canon has released their very easy to use. Additionally, color information is generally reduced as well, from 4:4:4 to 4:2:2. So if the raw data is the real information coming off the sensor, does that mean that it’s uncompressed? The RED cameras shoot in REDCODE, which has compression options from 3:1 to 18:1. 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. See product page for details. ‘Raw’ Review: Cannibal Coming-of-Age Movie Is a Modern Horror Masterpiece Intense French thriller on student with taste for human flesh is clever … Both raw and Log can be uncompressed, but that depends on the recording device. The new Sony, Canon and ARRI cameras all have a Log recording mode. And now the craving starts. So, going back to our original question, “Is shooting Log like shooting raw?” The answer is still “yes and no.” Hopefully, now you can see why.

While they're very different formats, they have the same general application. Her sister Alexia is in the year above. Well, it's still uncompressed in the sense that there has been no block, wavelet or temporal-based compression applied. However, it’s a special way of capturing that maximizes the tonal range of a sensor. These terms, and many others, have all become part of our vocabulary in this digital cinema world. Sony, Canon and ARRI have all taken the idea of Log film scanning and applied it to their sensors. The sensor outputs exactly what it sees—no white balance, ISO or other color adjustments are there. A dead ringer for the fictional future offspring of Paul Dano and Saoirse Ronan, the 19-year-old actor can radiate innocence, depravity or bewilderment in a glance, and toggle between humiliated and animalistically hungry on a dime. Raw recorders weren’t exactly common on-set gear though, so we have to hand it to RED for getting the raw party started in the motion picture business. Consider this a disclaimer, and a reclamation: The story of a young woman (Garance Marillier) who develops a taste for certain off-the-menu delicacies is indeed intense. The sensor information is always gathered before converting to a video output, but not all cameras let you record or output that data. While they’re very different formats, they have the same general application. 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). 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. This would be the closest thing to a true uncompressed signal.
