Production Tip: How You Can Prevent Corrupted Footage

first_imgPhysical DamageImage via Svetlana123.While less of a problem in many modern (solid-state) cameras, physical damage never bodes well for camera or media performance. A dropped, damaged, or otherwise impacted camera is under imminent threat of a host of problems, including damaged footage. Loose wiring, bad connections, or sensor or other essential components becoming loose or improperly seated all can cause some form of footage degradation or loss.PreventionUse a camera cage.Carry the camera with both hands.If any physical damage occurs, immediately verify functionality of camera and integrity of previously recorded footage. It is the job of every member of the crew involved with the imaging process to ensure data protection to the highest degree possible.

Errors During Footage TransferImage via gnepphoto.Even when you’ve gotten your card safely from camera to the card dump station, your footage isn’t in the clear yet. The transfer process is one of the most treacherous phases in the imaging pipeline for loss or damage of footage.During footage transfer, each bit gets replicated from the source drive to destination drive. This means that for your average video clip, there are several million opportunities for compromised data each time the drive gets transferred.PreventionAlways verify integrity of source media before transferring.Never adjust or change the filenames of source media.Never adjust the source media file architecture.Use specialized software tools to perform bit-for-bit verification on all backup drives to ensure proper replication of each bit from source material.Always ensure that no data transfers are in progress before ejecting media.Always eject media through the operating system. FormattingImage via Roung Chanthasiri.Improperly formatted recording media can also result in lost or damaged footage. This is because all cameras and recorders rely on specific file and media architecture to properly locate and store clips and metadata. If a card is improperly formatted, or formatted on a device other than the one recording from camera, there is a high probability of lost or damaged footage.Another factor to be wary of is “low-level clip deletion” — or deleting clips one by one on the camera or a computer. Deleting clips in this way can cause corruption. Always format the primary recording media in the device that records to it.PreventionAlways format recording media in-camera or external recorder.Avoid low-level clip deletion.Verify data integrity before transferring it to another drive. The ElementsImage via Jacob Lund.Let’s face it, if a fire, flood, or electrical storm breaks out on set, corrupted footage is going to be low on the crew’s priority list. As someone involved in the imaging process, however, you have to be aware of the threat these elements pose to footage integrity.PreventionKnow where camera and media are at all times.Know how they are secured.Know who is watching over them.In the event of an emergency, know how the camera and media are being looked out for. HeatImage via Baigazy J.Heat is a fundamental, unavoidable by-product of energy in our universe. In cameras, heat can cause a vast array of problems, including footage from noise to undesired camera shutdown. As with anything that causes improper shutdown, this opens your footage up to loss or damage.PreventionPower the camera down after each take in hot or humid environments.Keep air flowing over the body of the camera with a portable fan.Use a laser thermometer to monitor camera heat levels. Bad SoftwareImage via pixelform.All cameras are extremely susceptible to data integrity problems resulting from errors in camera software or firmware. This is a very simple side-effect of cameras being highly specialized computers. Regardless of any user error in handling camera or footage, if the underlying software is unreliable, your footage will be too.Before purchasing or selecting a camera for use on a production, make sure that there aren’t reported problems that could cause footage loss.PreventionResearch camera stability before rental or purchase.Always stay one stable firmware version behind.Read firmware notes for each patch.Read user reports of firmware stability before installing. Corrupted footage is every filmmaker’s nightmare. While there are some reliable recovery methods, let’s take a look at proper preventative measures.Corrupted footage is never welcome on set. In the last article on footage corruption, we discussed the basics of recovering corrupted footage. In this article, we’re taking a more proactive approach and learning how to prevent corruption from ever happening in the first place.Corrupted data or footage can arise from a variety of causes. Typically, this is the result of an error that occurred during recording, playback, or transfer of the clip. But your footage can become lost, damaged, or corrupted by a number of factors.Let’s take a look at what causes corrupted video files.What Causes Damaged Video Files?Damaged footage usually occurs during the read/write process of files. In a camera, this is usually during recording, playback, or transfer of the files from source media to a backup drive.Recording, Playback, TransferImage via pixelform.Each encoded frame of video contains millions of bits — the 1s and 0s of machine code that drive all modern tech. Each time these bits get recorded, accessed, or transferred, there is a high potential that at least a single bit gets replicated imperfectly.PreventionAvoid excess playback as much as possible.Don’t rapidly switch between recording and not recording.Avoid complex manipulation of the clips on the source media. Loss of PowerDamage may occur if power gets cut during recording, saving, playback, or while shooting with nearly depleted batteries.Image via ArmanO.Think of pressing the record button as writing a paragraph. Starting a recording is like the first sentence, which outlines the idea — stopping is like wrapping the thought up to move onto the next. If a paragraph lacks the breaks above or below, our minds read it as part of the flow of thought of both other paragraphs.With footage, each clip contains “headers and footers” that indicate that the data within belongs to clip x rather than clip y. If power gets interrupted for any reason before this data gets written to the media, chances are high that data on the card will become corrupted. Clips corrupted in this way will usually cause the entire card to become unreadable.Before a battery is truly depleted, a signal is sent to the camera to begin proper shutdown, where the clip “footer” is added to prevent media being corrupted from abrupt loss of power.Not all batteries are created equal, however. Third-party batteries can exacerbate this problem because most don’t interact with camera software in the same way as name-brand competitors.PreventionAlways use name-brand power options.Connect all devices that handle source media to some form of redundant power source.Always double-check that the camera is not recording before removing the power source.Keep the camera powered down as much as possible between takes.last_img read more

NBA announces 2019 All-Star game will be held in Charlotte

first_imgDon’t miss out on the latest news and information. The league had selected Charlotte to host the 2017 All-Star game, but later moved the game to New Orleans because of the state law restricting the rights of LGBT people. However, a compromise was struck in March to partially erase the impact of the House Bill 2 law limiting anti-discrimination protections for lesbians, gays, bisexual and transgender people.“While we understand the concerns of those who say the repeal of HB2 did not go far enough, we believe the recent legislation eliminates the most egregious aspects of the prior law,” NBA Commissioner Adam Silver said in a release. “Additionally, it allows us to work with the leadership of the Hornets organization to apply a set of equality principles to ensure that every All-Star event will proceed with open access and anti-discrimination policies.FEATURED STORIESSPORTSSEA Games: Biñan football stadium stands out in preparedness, completionSPORTSMalditas save PH from shutoutSPORTSPrivate companies step in to help SEA Games hosting“All venues, hotels and businesses we work with during All-Star will adhere to these policies as well.”Despite Silver’s intentions, the Equality NC and the Human Rights Campaign has concerns that no protections for non-discrimination policies for the LGBTQ community have been put in place by the Charlotte or the state.

That’s been dropped, but LGBT advocates have denounced the replacement law because state officials took no action barring sexual identity and gender discrimination in workplaces, restaurants and hotels and instead prohibited local governments from acting on their own.Hornets owner and longtime NBA great Michael Jordan said in a release he is “thrilled” the game is coming back to Charlotte.“We want to thank Commissioner Silver for his leadership throughout this process and for the decision to bring NBA All-Star back to Buzz City,” Jordan said in the release. “All-Star Weekend is an international event that will provide a tremendous economic impact to our community while showcasing our city, our franchise and our passionate Hornets fan base to people around the world.”ADVERTISEMENT Jordan asked Silver to keep the city in mind for 2019 after the league moved the 2017 game – hopeful the HB2 law would eventually be repealed.Silver honored that request.Hornets COO and president Fred Whitfield represented the Hornets and Spectrum Center in doing whatever he could to help facilitate a resolution, spending time meeting with legislatures and other business leaders in North Carolina.“From the very beginning I was in engaged to see if we could not only save the 2019 All-Star game, but the NCAA (basketball) regionals and the ACC Tournament, as well as concerts and events in the building,” Whitfield said. “We are operators of the building and we felt like we had to get engaged to assist to get some resolution.”Even as talks to repeal HB2 stalled at times, the Hornets continued to move forward with the league’s request to upgrade the arena.The $41 million renovation – $33.5 million of which came from the City of Charlotte – is almost complete, and has included a new scoreboard, new floor and renovations to suites and hospitality areas, among other upgrades.Charlotte previously hosted the All-Star game in 1991 at the Charlotte Coliseum, which has since been demolished.Pete Guelli, the Hornets executive vice president and chief sales and marketing officer, estimates a $100 economic impact for the city, but said the reputational effect will be even bigger.“This city has changed significantly since the last time it hosted a game 28 years ago,” Guelli said, “and the opportunity to showcase that on an international stage is incalculable.” Lakers win 9th straight, hold off Pelicans View commentslast_img read more

Kerala to be inculded in national industrial corridor

first_imgThiruvananthapuram: In a big boost to Kerala, the Union Government has decided to extend the Chennai-Bengaluru industrial corridor to Coimbatore and then to Kochi. The decision in this regard was conveyed to the state government by the National Industrial Corridor Development and Implementation Trust (NICDIT), a government release said. It had been Kerala’s plea for long to include the state in the corridor and Chief Minister Pinarayi Vijayan had made a strong pitch for the same. Also Read – Commercial vehicle sales to remain subdued in current fiscal: Icra The setting up of the corridor would contribute to developing manufacturing industries in the region and transform the Kochi-Palakkad region into a major manufacturing hub of South India. Two integrated manufacturing clusters (IMCs) would be developed–at Palakkad and Salem in Tamil Nadu, the release said. According to the norms of the NICDIT, about 2,000 to 5,000 acres are needed to set up the IMCs. However, after the Kerala government informed about the difficulties in making land available, the Centre has accepted the state’s plea to set it up in 1,800 acres. The state and Central government would jointly form a special purpose vehicle to manage the clusters, it was stated. The cluster in Kerala will come ip on either side of the Kochi-Salem national highway and is expected to provide 10,000 jobs.last_img read more
