I would use three pieces of hardware for this task. A recording laptop. A device that allows you to input the HDMI to the recording laptop, aka, a frame grabber. An HDMI spliter. A recording laptop Any old laptop will do, really. It doesn't need super specs, like dedicated graphics, but you certainly want at least a mid-range machine. Like an Intel i5 or ...

The latest and greatest HDMI specification is 1.4a (and version 2 is expected to be released this year). The fastest/highest bandwidth category of HDMI cable is "HDMI with Ethernet." The rating of a cable's shielding (Class 2, Class 3) has more to do with fire resistance and US wiring code and is not really relevant to the matter of signal loss. MyCableMart....

The short answer to your question is "no". The sample rate of video is typically measured in MHz or GHz. If you have a 1080p24 signal at 8 bits per pixel, the actual frame is 2750 x 1125 pixels (according to digital test equipment manufacturer Kramer). Multiplied by a 24 fps refresh rate, this results in 74,250,000 pixels / second. Multiplied by 10 bits ...

You already stated your options and you only have one that would work: you need a frame grabber. A frame grabber is a specialized chipset that does a very specific task. Sometimes such devices are called application-specific integrated circuits (ASIC). They basically do only one thing and they do it very well. The chipset that controls the USB on your ...

For amateur events, SDI may be overkill compared to using simple Component. The key for long runs is to separate the various components so that they don't degrade. There is a similar question here about long distance runs. As for HDMI to SDI, there should be no quality loss compared to HDMI as both are digital formats supporting full uncompressed HD ...

Native resolution is always better than non-native. If it only has a resolution of 720p, then it would have to be down-converting to that resolution which means it has to blend pixels which can produce artifacts from the pixel blending. (Notably, softer edges is the most likely.) Update: I'm sorry, re-reading, I noticed that it isn't native for either ...

You can probably do it directly through the EOS software. It is possible to get a live video stream from the camera over the USB connection. Note that USB2 is not going to be able to carry a full quality HDMI stream though. This is why the Intensity is USB3. It requires USB3 because the bandwidth requirements for the quality level it is working at ...

What solved the problem: Check your capture software settings. All settings (your monitor/capture device settings, your hardware settings and the settings in your capture software) should be correct and equal. What can help track down similar issues: Very likely a framerate issue. Only the 4K version of the Blackmagic Capture cards supports 60FPS and your ...

The TV still has to translate the color information and format, so there is, in effect, still some decoding on the TV. The difference is that it is uncompressed. The output from the device matches whatever the source captured, in whatever image format the source uses, but there is no loss of detail from applying compression. Compressed requires vastly ...

Some DSLRs output HDMI video that does not meet full HDMI specifications. It is not unusual to find combinations of source and destination gear that is incompatible. The HDMI can be viewed on permissive screens (consumer TV receivers, etc.) but not on more professional gear that strictly adheres to the HDMI standard protocols.

Setting your graphic card to work at a lower resolution will provide a small increase in performance in the case you described. For example: 1920 * 1080 = 2,073,600 1280 * 720 = 921,600 2,073,600 - 921,600 = 1,152,000, or 56% fewer pixels. If you spend all your computer's time working to create text to fill the entire screen with new information ...

If you’re going wired, you’re going to be limited to roughly 25 feet before you need to reclock the signal. HDMI simply isnt designed for long runs. There are 50’ cables out there, my experience is their performance is spotty. You could go with a Wireless Solution HDMI solution. I recommend the Nyrius line of transmitters/receivers which you can buy on ...

This should work: Hauppauge HD Personal Video Recorder 2 Gaming Edition Description The HD Personal Video Recorder 2 Gaming Edition from Hauppauge! allows you to record gameplay from your preferred gaming console in Full HD 1080p video.

a) You can't output 10 different video signals on your single HDMI output. Besides limitation of the graphic card of your computer, that would also require generating/reading 10 different video streams from your computer. One possible option, depending on your project aim and structure, is to produce 1 hi definition video stream from your computer and use an ...

I'm going to assume you want to view all 18 HDMI inputs simultaneously on a few monitors, then be able to send one of those inputs to an output for broadcast/presentation? I don't know what sort of effects you need, or anything else like that, but maybe this will get you on the right track. Or if you need the switcher to be seamless (i.e: no momentary signal ...

Only the 4K models of the Atom switchers support 1080p in 60 fps, like the ATEM 2 M/E Production Studio 4K. Although a software control panel is included, I would prefer a hardware panel. Switching between 18+ input sources will be so stressful, that you don't have time looking where the mouse pointer is. A hardware panel has big buttons and knobs that you ...

Mac Mini does not have HDMI input. GF6 has no video output through USB.

The problem is that the HDMI output on your T3i is not clean. You would still have all the UI from the camera interface placed on it. Higher end cameras (like the 5D mark iii) and some other makes have a clean output option, but I don't believe the T3i does. You can use the third party MagicLantern firmware to force the interface clean, but at that point ...

Speaking to the Canon technical team, it seems that at the time of this writing, there is no way on this particular model of camera to change the resolution of the HDMI output.

According to the specs on the Canon site your camera can record in 50i/p and 25p 1920x1080. Are you absolutely sure you can only get 60fps on the HDMI? Because that sounds rather weird that you get more FPS on the HDMI than the camera can actually record. If you set the recording option to 25FPS normally on canon cameras the FPS should also apply to the ...

Instead of the Teradek unit, I would try the new Epiphan Pearl, which can stream and record to/from multiple sources.

The GoPro would be a perfect candidate for what you want. It's a so called "action camera" and is a very robust (water tight with case) wide-angle camera that can shoot in very high frame rates with HD resolution (even more at lower frame rates). Suitable recording options for high speed sport events would 1080p @ 60FPS or 720p @ 120FPS. The camera also has ...

There are a plethora of capture cards on the market in that general price range from numerous manufacturers. There are two main things to worry about with these devices. First, for analog inputs, such as component video, you need to consider the quality of the analog to digital converters as well as what capabilities they have for scaling and format. ...

I've found an answer to my specific problem that's a little ugly, but might be of some use. The basic premise is to ensure that the first device in the chain does not support (or is capable of disabling support for) HDCP. Macs and iOS devices are opportunistic when it comes to HDCP; they'll always attempt to negotiate it, but will fall back to unencrypted ...

If cost isn't an object, I believe the higher end rack mount HyperDeck accepts an external timecode (ref in), but it's also quite a bit more expensive ($1000).

A 1.4 cable should work fine with a 1.3 signal, however an HDMI 1.4 signal will not work with an HDMI 1.3 cable or an HDMI 1.3 output unless the source is capable of using a prior standard.

At the present the highest category of HDMI cable shielding is Category 2

Pretty simple actually--running the signal through most HDMI splitters seems to work just fine. I can't be sure if this is a feature of all splitters, but Iv'e got two different models/brands of HDMI splitter and I can record HDMI just fine with 'em.

You would need a device that supports HDCP if your output source is utilizing it. That's the entire point of the system. The video signal is encrypted and will only exchange the data with a device which can cryptographically authenticate itself as an authorized HDCP receiver. Getting that certificate requires proving that they are going to follow the rules ...
