31 Янв. 2015 г.Инструкция gopro hd hero 2This digital signal is carried on coaxial 4.5 GHZ high definition rated video cable with BNC connectors. I'll have my son's sports car here for a year, so even though the FCar is off the road, I can experiment with his and see if I can improve on things. The Evertz is vital to crank the detail, bring up the exposure and match the colors of the cheap GoPro to match the other cameras on the show. I spoke with a truck engineer and video technician about what needs to be done to get the weak HDSDI signal from the GoPro into the truck switcher.Since then we went back to the nest but my shots didnt come out as well due to the camera being bumped and tilted upwards (tall guy bumped it on doorway). BTW: I'm not very technical, however, when looking at the arm and mounts I think the windnoise is generated by the mounts and bolts and not so much by the housing. I’m hoping to use my GoPro2 again in future games and other events, but I keep running into the cabling issue. I would hate to be a cameraman busting my back to cover the action, only to see a fixed lock-down shot mounted high behind me get replayed over and over on the broadcast. After digging into the tech specs and hearing from reputable sources the touted features were largely what they were claimed to be, we decided to share our take on this new tool. Some guy made a great set of titles with sound effects and stuff, and then he made a movie about how he made them. I tried several different power supplies and noticed that only certain ones worked properly. This is not compatible and a converter box is required to change the cameras output to HDSDI. The Hero2 is much more user friendly with a detailed LCD panel showing you exactly what format you are in. I'm still trying to use an external mike (the Zoom H1) and I'd just picked up some split insulating foam (normally used for pipe insulation) to try to isolate the body of the mike. And now GoPro has released a Hero2 new model that has sharper optics, an easy to navigate menu, better light sensitivity and more recording options. Good luck with the audio - trying to get rid of the wind noise is kicking my backside; there must be 100's of YouTube videos with helpful hints on how to get rid of it, but none of them seem to work to completely eliminate it. I’ve been looking into opening up more ways to use GoPros and other inexpensive cameras to create unique production styles. A scary proposition when you MUST have the camera working the entire game and match the other cameras on the show! But many of you may not know that these little cameras can output analog and HD signals that can be fed into a live production truck. If you can get the same clear results with the Zoom H1 at your intended recording locations (e.g. If anyone comes up with a trick for getting good exhaust audio with one of these, please share it!!! I was surprised that in ideal conditions the GoPro Hero1 cut quite well with broadcast rigs worth $100,000.00. Try not to mess with the other settings in the camera unless you completely understand the operations manual. Unfortunately I didn't have time to try it out before departing on a 4 week trip yesterday, so it'll have to wait 'till I return in April. You would only use this analog connection and output if you had a standard definition show. This converter box is just like the one mentioned above, but takes HDMI instead of component HD. I will break this blog down and try to explain to you how to get either a GoPro Hero1 or Hero2 working properly. If you want, you could drill through the side of the case to clear a path for the connection cables. This guy: Reducing Wind Noise - YouTube also makes some good points about isolating the microphone body and mounting. For some unknown reason, using a dead battery and the power supply results in failure after a few minutes of ac power. Here's a video shot from the passenger side of my TR to give you an idea to experiment with various mounting points. When there is limited personal or decks, these tiny cameras steal replays from a hard working hand held camera operator under the basket. Almost all professional television trucks require the incoming HD video signal to be HDSDI. They are sticking the mini-USB plug on the charger into the GoPro and plugging the other end directly into the wall. If you follow these guidelines exactly, these camera will stay powered up and passing video all day long. As I type this blog, GoPro does not have an AC power supply for this camera on its website for sale. The cable run must be under 300 feet or you will need re-clocking repeaters to push the signal along. CBS is using 5 volt .5 amp Motorola cell phone chargers and sometimes, these are not strong enough to keep these camera running. I even put it through a UpDownCross Converter from black magic and still could only get 720p. No company would dare say that it will work beyond that, but I’ve seldom seen it not work at lengths challenging that. This blog post will tell you how to do it and why most attempts to get these to work as live POVs prove to be an epic failure. In this second video, the guy is sitting in his car and demos the Zoom H1 audio and then unplugs it so that we can hear the difference. This has all the holes needed in the case to keep the GoPro protected and get the wires connected. It appears that I can only get the signal to broadcast over about 20 feet, but the cords I am running are 50 feet. I use the 2 USB connector 5 volt, 2 AMP (1 AMP on each USB connector) ExtremeMac IPU-ICH-11 10 Watt chargers. The folks at CBS are thing outside the box and trying to power the camera using third party (Motorola branded) cell phone chargers. It was two GoPro Hero 3 Silver cameras, one out on a pole behind the car, and the mics were two unpowered lapel mics feeding into a 2x mono to 1x stereo Y-adaptor and then into one of the cameras. For myself, I haven't dabbled with the GoPro since my car has been down, but this wind noise issue seems to plague all or most amateur recordings. The GoPro company makes a bunch of accessories for mounting these little cameras on almost anything. Be sure to turn the LCD screen off, after positioning and framing the camera, then plug in the ac usb power. Another good habit to get into is to properly stain-relieve all connections and tape them up. As a DP, these are an excellent way to add another hard to get angle of the subject you are shooting and the story you are telling. We have found that the new Hero 2 with the newer firmware is not compatible with our 2 ME Black Magic switcher. I have been experimenting with these cameras on college basketball games with CBS Sports Network. After speaking to many who have failed keeping the camera running off wall power, I did a few experiments. Talking to CBS Sports tech managers from cities all over the US, the biggest problem with these GoPros working is getting pictures back to the truck. You may want a super wide fisheye shot from behind a hockey goal or a less-distorted wide shot of a basketball court. But certain steps must be followed exactly to keep GoPros powered up and get pictures back to the truck.  Although we were hoping for 60fps 1080p and the 120fps is only Standard Def, there are a lot of game changers with this camera. Apparently some people have had some success with post editing software, but I don't even know what that stuff is, much less how to use it, nor do I really want to confront another software learning curve. Also, be sure to power the camera up first, on the battery, wait a second, then plug in the mini-usb cell phone charger to bypass the battery and run off wall power. The original Hero1 camera has a complicated menu system requiring the operation manual close by that I will only touch upon in this blog. I am constantly unable to run power extension for them and use USB battery packs and they can power it for hours, even days in time-lapse mode. We encountered similar problems with signal processing, but since we were using my GoPro2, we just connected it to an AJA KiPro, and sent the signal out via HDSDI to our Rattler. You are now ready to mount this camera, plug in ac cell phone charger for power and set up the rest of the gear to get the pictures back to the truck. Please enter your desired user name, your email address and other required details in the form below. This piece of machinery is expensive and most trucks only have a small number of inputs that can be dedicated to GoPros. I haven’t tested it, but a friend told me there is a 3-4 frames (25fps) delay on the output, not making the GoPro ideal for live production. The GoPro case could have dust inside the lens area and this will show up on screen because the lens is very wide. If you have serious problems, power cycle the camera by removing the battery for one full minute. CBS mostly uses the GoPros as non-essential slam cams mounted to the backboard, wide beauty shots high in the nose bleed section or as creative angles court side. These little adapters use single mode fiber in a venue (if it is available) to convert HDSDI signals to light. The Hero2 also has the analog mini hole and breakout cable to get standard definition RCA video into the truck if you want the 480p signal instead of HD. This new attachment will allow you to frame and control the camera wireless with a smart phone. I bought my Hero1 less than a year ago as I had the opportunity to visit a Peregrine Falcon nest at the top of our clock tower. I am running into a problem trying to get the HDMI signal from the GOPRO HD2 to a ATEm TELEVISION STUDIO by BLACKMAGIC. But these rattlers are expensive, you need a building with free single mode fiber and you have now made a $300 locked-down camera cost much more. Quik Pod is a monopod made to be used with Go Pro and lets the user take his or her own photo. There is also an analog RCA video and stereo audio cable to pull standard definition out of the Hero1. This little $80 accessory attaches directly to the back of the GoPro camera and gives you a tiny monitor to frame the camera. I have 4 GoPro cameras in my dirt track race car but can’t figure out how to get them to sync to the same time. This point of attachment lets you place suction cup mounts, bar mounts, ect directly to the housing. While we’ve all seen or participated in Youtube videos of jaw-clenching, scratching and surfing reminiscent of spastic action figures, the Go Pro has also enabled athletes to become filmmakers and photographers. I assume that you have tested the device on a standalone basis to double check that it works well (e.g. It is important to understand that these little cameras are format, frame rate and field of view switchable. I stepped over onto it from Adobe Premiere (which I found very difficult to use, and please note that I've used complex software for the past 25 years so I don't think it was me) and PowerDirector which was easy but a bit too limiting. After charging the battery for a bit, unplug the charger and set up the camera on battery power. The power requirements are 5 volts, 500-1000 milliamps which is what almost all cell phone chargers put out. So when Go Pro announced its new version of the Hero HD was “2X More Powerful in Every Way” we were excited. CBS have been shipping these GoPro cameras (old model Hero1 currently) around in Pelican cases to games all over the United States. The idea is to compliment the very expensive broadcast cameras used to televise the games with points of view (POVs) that are rarely seen in sports. First, plug the usb cell phone charger into the GoPro camera and make sure the red light on the front lights up. I recommend slightly higher than .5 amps if possible and closer to 1 full amp to keep the camera going. However, the occasional free-throw behind the backboard cut in live to show the ball going in could work. These are cheap connectors and cables, if you pull on them, the camera will cut out… or worse you will do permanent damage. I’ve got 32 of these cameras, and it never ceases to amaze me the new things people come up with on how to use them! When discussing this with a friend of mine he advised me to use a thick sock, cut a whole for the lens and slide it over the camera and mount. In the past, I’ve had to go through each file frame-by-frame to set them to the same time but it isnt exact. The Hero cameras have a standard two prong receiver mount on the bottom of all their cases. The biggest difference (as far of connections go) between the Hero1 and Hero2 is the HD output. Using an inexpensive (sold separately) mini-HDMI to HDMI cable, you connect the GoPro Hero2 to a HDMI to HDSDI converter box. These are a bit more expensive and do the same thing as the Black Magic units, simply convert one type of HD signal to another. I’m looking for a cheap solution to livestream Mountain Bike Races and this system looks fantastic. After all, the original Hero HD was arguably, along with the DSLR, the most impactful piece of technology action-based filmmaking had seen since the rise of video. The light down to the truck is changed back to HDSDI using the second half of the rattler adapter and brought into the truck with very little loss. Another thing I figured out after trial and error is that you must charge the GoPro battery to about 25 percent before you use it off AC power. If you are working in a sports arena that is older than 3-5 years, there is a good chance that the cable run in the conduit is regular coax and will not pass HDSDI. On the broadcasts I have been on, the director mostly used these cameras as an alternate angle to post graphics, score and stats over. I have mostly worked with Hero1 cameras with CBS, but the theory of converter boxes, HDSDI cable lengths, power supplies, protective cases and use of Evertz is the same with Hero2 cameras using HDMI out. Nice shots so far were on the side window behind the door, this also shows some driver actions. To help you visualize the setup with Hero1 cameras, please watch the twitvid below from a college hockey game. The Hero1 camera includes the break out cable, the Hero2 only comes with an analog cable, you need to buy a mini-HDMI to HDMI cable. For under $300 you get a tiny wide angle 16:9 1080p camera that is also a self contained video camcorder.  |
