Blackmagic Design Video Assist 4K and Atomos Nijna Blade HDMI recorder overview. These devices record the output of a camera or computer via HDMI, and are heavily used in the production of ExplainingComputers content. So, as many of you ask have asked how I record a computer on this channel, I thought I’d make a video about them, as well as various other HDMI accessories that I regularly use.
Links to equipment shown in the video (updated 22 March 2020):
You can find the Blackmagic Design Video Assist 4K on Amazon.com at: amzn.to/2UtSTCk You can also find out information on this and other similar HDMI/SDI recorders on the Blackmagic Design website at: www.blackmagicdesign.com/prod...
Or on Amazon.co.uk at: www.amazon.co.uk/dp/B01EKJ944Y...
The Atomos Ninja Blade is an older device and no longer widely available. But you can find information on all of the current Atomos HDMI and SDI recorders here: www.atomos.com/
HDMI splitters like the one I show in the video are manufactured by many companies. Models very similar to mine (which is no longer listed) -- and which are probably internally identical to it -- include:
On Amazon.com: amzn.to/2FAVTbg
On Amazon.co.uk: www.amazon.co.uk/dp/B00LM4IJ60...
HDMI female-to-female couplers are also made by many manufacturers, and include:
On Amazon.com (2 pack): amzn.to/2FO8SCr
On Amazon.co.uk (same product, single pack): www.amazon.co.uk/dp/B06XR8RBTQ...

I'm glad you're a RU-vidr interested in film making who actually has other interests and is able to make interesting films rather than just special FX heavy clever shots with no dialog or story like so many others. Thanks for all you do.

I stumbled on this channel about a year or two ago looking for some info on Raspberry Pi and GPIO. What a gold mine I stumbled on! I look forward to my Sunday subscription alerts on RU-vid. THIS is how a video should be done. THIS is professional. Nearly all videos are under 15 minutes. They contain relevant information and do not ramble. Brilliant work! I also enjoy his other channel. I hope this is profitable for him. If this isn't my #1 RU-vid subscription, it is in the top 5 easily.

@SlowPCGaming1 4 года назад

This was great. I love how you showed more of your emotions and became more animated in your explanation and excitement over this topic. From the hardware you've shown it is rather easy and not that expensive to make recordings of 4K or lower resolution protected content. The new 4K Atomos Ninja V is only $649 I believe. With your splitter that strips out the protections and one of these HDMI recorders all you really need are large enough capacity SSDs or laptop grade 2+ TeraByte hard drives.

Quality content since day 1 of me finding this channel some time ago (years, in fact). Even the videos of stuff I am familiar with I still watch even if they are just going over the basics. This channel really reminds me of the oh-so-awesome stuff from the late 90's - early '00s such as Beyond 2000 (which we didn't get in the states back then, only some re-runs that aired on PBS). Our closest was the (again, so so awesome) Computer Chronicles with the one and only Stewart Cheifet -- who's still around! Great stuff Mr. B -- please keep them coming so long as you still enjoy making them. Cheers!

@jmtnvalley 6 лет назад

This is way more sophisticated than the HDMI recorder I have. I bought a ClonerAlliance HDML-Cloner Box on Amazon. The interface is VERY basic and it can be hit or miss at first. It often creates a series of smaller files to a USB memory. I process these through a video converter to merge them, cut out parts I don't want and shrink the file a bit. Thanks for the great video.

Thank for giving us a background on your video kit for RU-vid. I have often wondered how individuals got shots of BIOS screens so clear and without reflections. I think this week's content fits in with the channel's goal, because I assume HDMI recorders are essentially special application computers. As always, thanks for a great presentation.

Videography has certainly come a looong way just in my lifetime. I took two years of Video Productions in high school where our equipment was primarily SVHS (I was the only student that bothered with the single Sony Hi8 we had) and it's simply amazing how much technology and videography has advanced in the past 22 years. Thanks for the behind-the-scenes look at how you produce such amazing videos!

@reggiep75 6 лет назад

Great video, Chris. I'd been curious about BIOS shots and other not easy to grab footage and had already come to the conclusion you had to have been operating standalone recorders. I just never realised it was some real quality kit (with a massive price too haha) that makes common sense when you're looking to achieve the shortest and most reliable and defined workflow and all the equipment you have makes the best sense. I do remember you showing the Ninja Blade in a previous video.

@HWolfeIII 4 года назад

Thank you. You have great timing as my son wants to get into making movies and he's 6 now. So I've gotten a nice camera but trying to see what HDMI recorder to use. And he's using Hitfilm that you spoke of earlier, so all of this has been great timing for us. Keep up the great work.

@bigsky1970 6 лет назад

Enjoyed this video. Really nice that Black Magic created and developed a dedicated piece of video hardware. I was also impressed with even the velcro ties oddly enough. I've been using the plastic zip ties for so long, I think I might just switch to the velcro ties as they'll be a lot more convenient, especially mounting or moving cables all the time.

@SergiuszRoszczyk 6 лет назад

I’m glad that you showed that sometimes a dedicated hardware solution is better to do the job than a lots of software replacements. Of course you can record live footage on a PC but it is much more convenient to just get job done and download a file. And then you can apply all the fancy effects in software. I like this tiny HDMI splitter. I think I’ll buy one to strip HDCP from Mac video. It happens sometimes on conferences that video mixer rejects keynotes from Mac due to HDCP. It would be better solution than downgrading to analog VGA out.

@ExplainingComputers 6 лет назад

The "splitter" is indeed a very handy device. They are all of course sold as "splitters" . . . ;)

@geminibodyshop71 6 лет назад

it shows you don't need the highest end pc or laptop but the pro kit behind the camera is so important to make great videos

@ExplainingComputers 6 лет назад

Well said. I could make videos with less professional kit. But It would be harder and more time consuming, and this would make uploading a new show every week far more difficult.

@geminibodyshop71 6 лет назад

also it shows people everything you want to do on your pc or single board computer or laptop doesn't need screaming high specs and processors we cant afford well I cant my pc I high spec now 5 years ago it was crazy but ill get another 5 years out of it money well spent and well spent time watching your videos

@ExplainingComputers 6 лет назад

Very true. Most PCs from the last 10 years can do a great many things -- there is less and less reason to upgrade if your focus is what you want to achieve with a PC, rather than having the latest kit. I edit on a PC that is largely 8+ years old. :)

@XSpImmaLion 6 лет назад

Ooooh, those are nice. I didn't know you used them Chris, thanks for sharing! They are unfortunately and justifiably very expensive... thought of getting them at some point but ultimately gave up and am trying to look for an alternative. But man, they do ease up workflow quite a lot. Thing is, professional alternatives can get way more expensive than that... like a Tricaster, or some other professional switcher board with everything integrated. The usability of those goes more towards livecasting and whatnot, but I follow some non-live channels that makes use of them just for the streamlined workflow. Good for people to know though, it's not that you absolutely need external recorders like those, it's just that they really help, specially in speeding up workflows. I have a reversed professional history than that of Chris... I first graduated in computers, and then around 10 years later I also graduated in journalism. My dad also worked with computers, but at the same time he had a hobby level photo lab at home (converted restroom), both of which I guess influenced me. :P But I don't have anywhere near the professional curriculum that Chris have, just lots of curiosity. xD Anyways, great stuff!

@joesalyers 4 года назад

@@ExplainingComputers I've ran a professional audio recording studio since 1998 and worked on major label records and movie soundtracks, but video hardware was never on my radar until I started my RU-vid channel. I've always been into FreeBSD MacOS and Linux as my hobby but I love creating videos. It's a bit less complicated compared to audio since you can see the footage you are working with in video compared to mixing a record with is basically working blind using your ears. Funny enough I went searching for a capture card and was looking at units used by gamers but the quality of those boxes was no better than software recording just less system intensive. But then I saw your NomadBSD video and the text was CRISP and the colors were ultra accurate so I had to find out what capture card you were using. I ordered the blackmagic sdi/hdmi box this morning after looking it up on B&H and to be honest it was not as expensive as I thought it would be. I paid 5 times as much for an audio A/D converter for our mastering room just 6 months ago so it's not much more than the less than adequate gaming capture cards. I also purchased the new Mac Pro 16 core for the studio since we use Avid's Pro Tools HDX and we need PCI slots for the DSP cards and I also grabbed the Afterburner card (tax write-off 😁) just in case I found a ProRes Camera later on. But the Blackmagic Video Assist can record in ProRes so I shouldn't have any issues with playback with the afterburner! Thank you for all of your help I truly appreciate it!!

Oooh, that was an interesting look at some fancy professional technology we plebians don't have access to. It's something not seen often. Anyhow, filmmaker first, computing guy second, huh? Reminds me of James Rolfe: he always said that he was an amateur filmmaker, but then in 2006, his Angry Video Game Nerd web-video series got big, and now he almost exclusively does video game related stuff on RU-vid. Yet, I must say: cinematographicly, his videos are at the top of their class. That must be because of his traditional filmaker's attitude to his his work.

I curious why HDMI input for PC isn't more common. what's the difference in cost between an HDMI input for TV/monitor vs HDMI input directly into the PC. I remember having a graphics card with S-video/components like a decade ago and it was really handy. Don't recall it being more expansive than other cards.
