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 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 ...

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 ...

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 ...

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 ...

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 ...

Download Sparkocam and your problem will go away. I am using a T3i and a T6i for the same live steam. Your other option is remove autofocus from the lens and switch it to manual

First: 4k for livestreaming is pretty overkill. Please remember that your streaming device (your computer) and internet upload speed need handle this... AND to top things of not all of your viewers will be able to watch the stream in 4k because of their internet and missing out 4k devices. Alpha Gaming (Harris Heller) is covering everything you want to know ...

EVERY place the computer CPU connects to the rest of the world requires an interface (hardware and software) of some kind. There is a very complex interface to get the data out of the computer and on to the screen where you are reading these words. And another interface to capture the key-strokes and convert them into characters entering the computer. And ...

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 ...

Cerevo Liveshell 2. It,s battery powered also. As receiving-end use a laptop with vlc player. Hdmi from laptop to mixer. I used this setup a few times.

Nitero Is looking to create a wireless solution for VR by the end of this year, which very well may apply to what you need as well. At the very least, if this technology does get off the ground we may see higher fidelity wireless solutions for video be produced off the back of this technology in the coming months/years. Basically, it might be worth waiting a ...

Yes, they exist. They are called HDMI wireless extenders. Sometimes they are called transmitters/receivers. No, the good ones are not cheap. Further, I don't know of any where the receiver does not need external power. Here's two examples, a better one and a not so better one: IOGear Matrix pro (Here's a different offering) Gefan Long Range Extender I ...

Which Lilliput monitor do you have and what exactly is the output format of the 5d Mkiii? Not all Lilliput screens can display progressive resolutions. Sometimes cameras provide "fake" interlaced on the monitor out (PsF) even if recording progressive to avoid that problem. It is a common problem with the BM Pocket Cinema Camera and (some) Lilliput screens ...

Bandwidth issues aside, HDMI is "protected" by HDCP, which prevents you from doing anything like this. Depending on how noisy your neighborhood is RF-wise, this could work for you: http://www.amazon.com/Nyrius-Transmitter-Streaming-Satellite-NPCS549/dp/B009E6R89C

By late 2018, the category "HDMI recorder" (#2 of your 3 questions) has become a commodity. Passthrough is taken for granted. Online retailers and auction websites have dozens of models for around USD 100, with new clones appearing every month at half that price.

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.


1

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 ...
