  • Wireless Video Transmission in a Backpack

    H.264 and H.265 Video Encoders

    When you are in need of a system to help with video transmission, the quality of your video output will be hugely dependent on the quality of the encoder that you use with your file. Encoding a video recording converts the raw file into a compressed format without affecting the quality of the image to be played back, giving you the best-looking video possible. Therefore, for a wireless video transmission system it is particularly important that the video encoding that you use is as efficient as it possibly can be. With this in mind, H.264 and H.265 encoders are the only way to go if you want the best quality videos.

    H.264 video encoding is the professional standard for video compression, used the world over for professional cameras. H.264 provides great quality video, but at far lower bit rates than previous industry standards. This means that the video file sizes are vastly decreased, which is ideal for professional wireless video transmission. Be it an important world news story or a just a sports game, it is vital that you have the capability to record as much as possible. In addition to this, it is critical that you are able to record in as high a quality as possible at the same time. By using H.264 to encode, both of these requirements are met.

    However, H.265 is a new high efficiency video coding technology that can provide the newest compression standard. The goal of H.265 encoding is to provide twice the compression rate of H.264, which can be used in 2 ways. You can either record identical video quality to H.264 but compress this to half the size, or you can provide demonstrably higher visual quality at the same file size.

    Teradek Bond Backpacks

    The Teradek Bond family of backpacks are an all in one wireless video transmission system especially made for for the Teradek
    HEVC streaming solution that give you the professional quality discussed. The Teradek Bond Backpack come with a custom modem that gives the capability to pick up cellular coverage, and capture footage at a far higher bitrate. However, the Teradek Bond 759 VU backpack most importantly houses built in H.264 and H.265 encoders, allowing you to stream up to 1080p resolution. With an optimised system that boots up in under 20 seconds, the functionality of the backpacks are second to none as well. Top quality connectivity wherever you need it, an internal battery for power back up while you swap power sources and an ergonomic, lightweight design all mean that the Teradek is perfect for all requirements, including use with professional cameras.



  • What is a Spectrum Analyser

    Finding Affordable, High Quality Spectrum Analysers

    A spectrum analyser is a device that is used with other types of broadcast equipment in the fields of cinematography, broadcasting and content creation to measure the power of the frequency spectrum of audio and radio frequency (RF) signals.

    Analysers are items of professional equipment that offer a reliable and convenient visual representation of signal amplitude (strength) as it varies by signal frequency. Each analyser has its own illuminated LCD display screen where the amplitude of the signal is represented by the vertical axis, and the frequency is represented by the horizontal axis.

    What it is used for

    For those involved in cinematography, broadcasting or content creation, reliable and trustworthy transmission is vital, regardless of the conditions on set. Furthermore, what is important is not just the quality of the broadcast equipment used. It is the signal strength that matters as well, and signal strength is often dependent on the amount of RF interference locally. With so much at stake, the engineers at Teradek LLC were tasked with developing a spectrum analyser that addressed this crucial problem and makes it much easier to find interference-free channels to use.

    The Bolt range of Spectrum Analysers

    Teradek Bolt

    The solutions our engineers came up with are practical and high quality, yet affordable.

    Teradek have an enviable track record of developing high-quality professional equipment and are now able to offer a choice of three high specification spectrum analysers - the Bolt 500, Bolt 1000 and Bolt 3000. Each of these devices share many of the premium features that have made Teradek’s spectrum analysers so popular.

    At the same time, each model has their own unique set of features that have been developed to meet the high demands of professional cinematographers, broadcasters and content creators.

    The main difference between the models is their operating range. The Bolt 3000 has a 3,000 ft operating range, the Bolt1000 has a 1,000ft range and the Bolt500‘s range is 500ft. If you are looking for a spectrum analyzer that utilises 20MHz channels the Bolt range can help. The Bolt 3000 also offers 24 x 20Mhz channels (although it cannot utilize interlaced, PSF, or 1080p60/50 at this time).

    The Bolt 1000 and 3000 are smaller and lighter than previous models and have better heat resistance.

    The Bolt range of spectrum analysers has been designed to complement your existing broadcasting equipment. You can be certain that Teradek has designed a device that not only meets your requirements but that each device has been manufactured by a company dedicated to producing high-quality spectrum analysers at affordable prices.

  • The Kandao Obsidian Professional 360° VR Camera

    The Kandao Obsidian Professional 360° VR Camera
    Virtual Reality (VR) rose from obscurity back in 2015 to become a trend in under three years. And, now, VR videos are getting insanely popular all over the globe. Mind you, we are no longer just talking about immersive gaming technology; but the remarkable ability to create super spherical flicks and amazing VR videos using 360° cameras.

    VR videos provide a first-person visual experience to give you the impression that you are present at the scene. They also give you a sense of depth as you can look around and see what is happening in every direction. However, you need to adhere to specific parameters for movement and placement of the 360° cams.

    Capturing a VR Video

    When filming with a 360° professional camera equipment, there is no "behind the camera" situation as the camera's field of view spans around the whole environment encircling it. Thus, you need to clear all clutter, or at least ensure that you do not mind having the things or activities around you in the video.

    Camera placement is highly dependent on your storyline. The role that you want the viewers to play in the video should guide you. If you want them to spectate, then you should place the camera outside the activity. But if you want them to feel like participants, then you set the camera at the heart of the activity. Remember to place the 360° camera approximately 6 ft high for an eye-level visual experience.

    The 360° camera needs to move in all directions. You should ensure that the camera's movements are smooth and stable. However, whoever or whichever device moves the camera will appear in the final footage. Although, it is possible to edit them out.

    Meet the Kandao Obsidian

    Several tech giants took Facebook's decision to make its 360° 3D video capturing system (Surround 360) open source as a challenge. Many companies went back to the drawing board, but a year later, only three earned Facebook's recognition. Among them the Obsidian R: an 8K high-resolution 360° VR professional camera from the little-known, China-based Kandao Studio.

    The Obsidian R captures 360° photos in 8k resolution using a system of six integrated fish-eye lenses. It then employs a seamless "one-click" software to stitch footage at one frame per second to generate high-quality stereoscopic panoramas.

    Kandao Obsidian R

    The "one-click" software speeds up the post-production process by eliminating complex steps. The system allows you to complete 3D panoramas with just a touch of a button, literally. The camera also learns your preferences and stitches your footage automatically after a short period of use.

    The palm-sized Kandao Obsidian is light, rugged, and highly portable. It features three powering options: an external 12V charger, two batteries, or an Ethernet cable. The Ethernet cable facilitates file transfers and image setting controls thus eliminating the need for slow HDMI cables and costly HDMI capture cards.

    The Obsidian's suite of software solutions with a comprehensive range of rich functionalities is perhaps what earned it the 2017 CES' "Best of Innovation Honoree" in the Digital Imaging Product Category. It comes standard with new-user-friendly software for stitching, editing, post-processing, video encoding, and live streaming. The only downside is that you have to purchase a license for live broadcasting.

  • What Is a White Box Lens?

    When shopping for broadcast lenses, you've probably come across listings that describe the item as a "white box lens." What exactly does this mean?
    A white box lens is a lens that was originally part of a camera kit that the retailer bought and subsequently split out into separate products. Instead of having retail packaging, these lenses come in a plain white box. They have the same quality as retail lenses, as well as the same warranty, but they are usually less expensive. Sometimes they are considerably less expensive.
    White Box LensThis means that white box lenses are a suitable alternative when buying broadcast lenses. You just need to make sure that the lens came from a kit that was intended for your country. For example, if you live in the US, you need to ask the retailer or seller if the lens came from a kit intended for the US market. If it didn't, then the lens would be considered a "grey market" item.White box lenses are often confused with grey market lenses, but this is a mistake. A grey market lens is one that is being sold in a market different than what the manufacturer intended. This lens would not have a warranty from the manufacturer. It could have other problems as well, such as missing or incorrect documentation, and inferior quality.A grey market lens could be sold as a white box lens. So. how can you identify when this happens?Grey market lenses will often have one of following terms in its description:

    • Import Model
    • Warranty via Seller
    • USA Seller Warranty
    • Off Market
    • USA Coverage by Seller
    • Seller Warranty


    You can also avoid grey market lenses by buying from a reputable retailer.

    White box lenses should also not be confused with refurbished lenses. A refurbished lens is one that has been returned to the manufacturer, who then corrects any faults in the lens before reselling the item. The quality of a refurbished lens is usually the same or close to the same of a new lens, but it often comes with a shorter warranty period.

    Like with a grey market lens, a refurbished lens could be sold as a white box lens, but it should explicitly state
    that it is refurbished. A white box lens does not imply that the lens is refurbished.

    So, should you buy a white box lens?

    Yes. You will get the same quality and warranty as a retail lens, and you'll save money. You just need to look out for grey market and refurbished lenses being sold as white box, and the best way to avoid these is to buy from a reputable retailer.

  • Transfer Video From Panasonic Camcorder to Computer

    You just shot a video on your Panasonic camcorder, and now you want to transfer that footage to your computer. How this is done depends on the type of camcorder and computer being used.

    Older Panasonic camcorders utilize a cable connection called FireWire. This is often found on camcorders that use video tapes for storing footage. The computer needs a FireWire enabled connection card, and a special cable is needed to connect the camcorder to the computer. Some models updated this connection with a USB connection. From here, software is needed to record the data. Some models of camcorders ship with software to be downloaded to the computer that allows the footage to be imported, but many computers ship with some form of software for footage imports.

    Transfer Video From Panasonic Camcorder to Computer

    A modern day Panasonic camcorder often stores footage on a medium known as the SD card. These are formatted to record based on the requirements of the camcorder. To transfer footage from this type of storage device, the SD card usually must be removed from the camera. The card can then be inserted into a builtin SD card reader on the computer or inserted into a USB card reader which can then be connected to a USB port on the computer. An adapter like this also exists for lightning connections to import videos to an iOS device, if need be.

    Importing From an SD Card

    Most computers made today ship with built in software for importing videos. Windows Movie Maker is a basic editor for Windows machines that enables the import of digital data from the SD card. iMovie is the software available for the Mac.

    Additionally, when the SD card is inserted in the computer, it appears within the file navigator and can be accessed like any other folder on the computer. Within the SD card folder is a video folder, either labelled to be a videos folder, or labeled as private. Within this folder is an AVCHD folder, and in this folder are the video files. They will be numbered and ordered chronologically based on when they were created. From here, the files can be copied into folders on the computer, then the SD card can be ejected. It is important to copy the files onto the computer so that the video editing software on the machine can find the files. If these remain on the SD card, the video editing software will not be able to find the files when the SD card is removed.

    Importing from FireWire to Ma

    Most Macs manufactured between 2008 and 2011 included a FireWire port built into the machine. To import footage over FireWire, the tape of the camcorder must be rewinded to the beginning of the footage, then software on the computer is used to record the tape information as it is played on the camera. Older versions of iMovie are able to natively import footage over FireWire. The Adobe suite of video editing software is also able to natively import footage.


    Importing from FireWire to PC

    Not every PC ships with a FireWire capture card. These can be purchased separately, then added to a desktop setup. For a laptop, it would need to already ship with a FireWire port to import via a FireWire cable. Assuming the hardware is present, the next step is the software. This follows a similar procedure as the Mac, where the software must be set to capture the footage playing on the camera. The tape of the camera must be set to the beginning of the footage before importing through the software. Windows Movie Maker is the Windows alternative to iMovie (which is a Mac exclusive). The Adobe suite can also be used here and any prepackaged software that came with the camcorder can also be used for importing footage.

    For both Mac and PC, the software gives options for quality settings and locations for the import. This stores the files on the computer to later be imported into the video editing software. The import software can then be closed and the camera safely ejected, either by selecting the eject option on the Windows start bar or dragging the camera/SD card to the trash on Mac.

  • Best Handheld Camcorder for Short Filmmaking

    A short film isn't limited to a linear story line meant to express a cohesive story. Short filmmaking is such a broad subject that it can apply to any type of recorded media across a spectrum, the usual short, music videos, experimental film, commercials, and so much more. As such, it goes without saying that there is not likely to be a one size fits all solution to what you're looking for to tell the story best within your particular project's vision.

    Handheld Camcorder for Short Filmmaking

    The good news with today's long reaching resources, for the beginner filmmaker hoping to get their feet wet but with little budget to speak of, things like editing software and even lighting equipment can be found for a low price online. Some software can even be acquired through free or low priced apps and downloaded easily to personal laptops and tablets. What to do about the actual recording equipment itself? There are plenty of options to choose from for those just starting out with building a decent reel through the act of short filmmaking.

    While it may not scream "super pro status" there is actually a lot to gain from starting out as a short filmmaker using handheld devices. Handheld camcorders come in a variety of sizes and an even wider variety of added features. They're an inexpensive way to get used to being behind the lens and are easy to transport to pretty much anywhere you might be hoping to shoot. The truth is that, even if it isn't a snazzy, expensive studio setup, handheld camcorders can potentially shoot at a high, clean quality, just as long as you know what you're looking for in a device. It's also not impossible to make a "documentary" styled short film look just as pro.

    First, figure out what it is that is causing you to seek a handheld camcorder. Then, figure out what types of features you're needing in a setup. The very best camcorder will differ depending on what it will be needed for. If it's a question of price, portable camcorders will always be offered in a variety of prices. If you're looking for a cheap handheld cam, then any old HD camcorder new on the market should do. If you're needing something a little more specific, then the price will likely go up.

    If you're looking for a device with a more intuitive ability, such as something with more gimmicks and better control over zooming, panning, light adjustment, better focus, and so on, then a simple HD camera simply will not do. What most students of film go for is instead a DSLR cameras, which offers the ability to change lenses at the drop of a hat. It's being able and willing to extend the extra few hundred to receive the added benefits that DSLR cameras offer that make all the difference to the quality of your short films.
