Breaking the 30 minute video recording limit without breaking the bank past Leon Watkins (Website

Summary: I’ve built a portable, lightweight rig using a gaming recording device to tape a clean HMDI feed direct from the camera for continuous takes of over thirty minutes.

The rig mounted on a tripod and in apply

One of the major frustrations I’ve had over the years is people request me “do you do videos?”; to which I generally reply “no”, and and so endeavor to requite them the number of someone who can practice a decent chore. However, in that location are occasions when I practise desire to practise video, and for me these are ordinarily long, static viewpoint events which terminal over the magic 30 minutes. For me these are personal events such as school plays or sermons at my church – but I see the need for lecture recording, or presentations amidst over situations. Historically, I’ve kept a firm heart on my watch whilst nonetheless trying to enjoy these events, jumping upwardly 5 minutes before the end of the recording period and trying to find a suitable 2-3 second window to end and restart recording whilst trying not to distract everyone else (including the speaker). It all feels a bit mission impossible and I felt there had to exist a better way. I recently did a book launch where I was doing both stills and video which was a little bit of a nightmare of clock watching over a iii-60 minutes event.

Permit me be clear – I’m non a video pro. I’1000 not demanding raw output with exotic codecs or doing much mail service processing, colour grading or whatsoever of that sort of thing. At that place are people who are much better placed than me to make loftier-quality productions for commercial use – and I volition happily pass and then piece of work. Only for personal and community stuff, all I really want is a clean image with clean sound and I’m happy. Information technology’southward for personal apply and posting on youtube customs groups. Then please be aware that this solution is for those needs, not high-finish professional output. With all that beingness said, I was pretty pleased with the results I got from my cheap setup.

Cost. This was my major concern. The sharper-eyed among y’all will run across that the camera I’grand using to model this setup is a D850. So, If I’ve got a D850, why wouldn’t I spent another few hundred $/£s on an Atomos Ninja Flame Ninja (

with SSDs, or get the slightly more affordable new Blackmagic Design Video Help (HD) (

) along with associated batteries and mounting rigs? Why not indeed? Because I thought there must be a cheaper solution. It just seemed that jumping feet first into a fully professional setup for something I didn’t practice professionally would be a huge leap of both faith and personal resources. So I decided to wait for something which would do the task at a consumer/enthusiast level.

I knew what I was looking for – a device that would record a make clean HDMI feed from the camera. I knew that with my bodies (D500 & D850) setting upward a clean HDMI feed (i.eastward., an output without all the monitoring and menu text) would be fairly straightforward. To cut a long story short, at that place really isn’t annihilation available at consumer or enthusiast level marketed specifically at photographers. I’d be happy to be proved wrong, but I couldn’t observe annihilation. However, in my enquiry (Googling “HDMI external recorder”) I came across the gamer communities apply of live streaming and game recording devices, which are basically hardware boxes which sit down between the console and Television set, mostly with a USB cable off to an attached estimator. Notwithstanding, there were some that also included the power to tape directly to a USB host. And I plant a particular range that recorded direct to a SD card.
When I saw this I idea it was worth taking a risk and seeing if I could get it working to intermission the 30 minutes barrier.

The particular hardware that seemed to tick all the boxes, and also expect fairly not bad was the AverMedia Live Gamer Portable (
product page
); likewise known under the model number C875, a device with similar dimensions to a thick smartphone, with the added ability of existence USB powered, which offered up the possibility of existence run from a battery pack, rather than having trailing mains cables. It was an older model, just recording at 1080p (there is a newer v2 model which offers 4K recording): – however this was ideal I was just looking for HD recording.

So I decided to assemble the parts to become my trivial rig together, after a lilliputian trial and error and proving that the concept worked, my total parts and prices (Great britain sites in GBP, equally I’thou based in the United kingdom of great britain and northern ireland) were:





Avermedia C875


Reckoner Exchange



This model is discontinued but widely bachelor used

External 12 000 mAh bombardment pack



Bought mainly for course gene

Generic 10cm Mini USB cable



The socket on the C875 is a slightly former mode (mini)

Silicone smartphone handlebar mount



I overspent on this, you can get far cheaper than this

1.8m HDMI cable



This brought my total outlay to £93.43. I overspent on the handlebar mountain – whatever generic silicone handlebar mount will work and the battery pack has a capacity well beyond what I need (on testing I think I tin can easily get >eight hours of recording from a full charge); I chose it mainly on the form factor – matching the C875 and able to fit in the handlebar mount. I chose the handlebar mount every bit I thought it would fit nicely on a tripod leg, which it does. I also considered hanging the lot in a net pocketbook under tripod, but the handlebar mountain looks a lot neater and is more secure. I stock-still the C875 to the battery pack with a few nix ties I had lying around, which you can see in the photos. I’g sure black zip ties would exist neater but white ones were what I had to hand.

Setting upwards a make clean HDMI output from the D850 for external recording is adequately simple – there’s a really concise


guide for the D800, just if you want the carte basics it’s hither:

Setup Menu > HDMI >

one) Output Resolution = AUTO (or 1080p);
ii) External recording control = Off;
3) Avant-garde>

Output range = Auto;
Output display size = 100%;
Live view on-screen brandish = OFF;
Dual monitor = ON

The setup for the C875 proved a little trickier to get right. As information technology’s an old, discontinued model, the drivers for modern OS’south (particularly Windows) seemed to exist very temperamental, with plenty of forum users experiencing problems getting the interface working at all. I probably spend 4 hours to get 85% there before I worked out that I didn’t actually need to have an interface to become the recording working properly. So, I’ve not been able to do some of the subtler recording tweaks such equally changing the default recording bitrate (which is 12Mbps) that are available if you get the customer software working (tutorials can exist found

), just I’ve found that the default settings that were on my device worked fine.

The chief issue when troubleshooting the C875 is that information technology has pretty much i error indicator – a blueish flashing band. Which could mean multiple things. I plant that the issue I had was a “mis formatted” SDXC bill of fare – I found the solution was to reformat the exFAT SDXC to Fat. Avermedia provides a link to a utility for this on

this page
. Once I’d done this the blue ring disappeared, and when powered upwardly the C875 will flash red for about 10 seconds and then settle to a solid red ring, at which point information technology’s ready to start recording. When a HDMI feed is connected, a printing on the central push will outset recording (if the output switch is prepare to SD card) and this will be indicated by a pulsing blood-red calorie-free on the band. Whatsoever blueish lights will betoken that y’all’ve got something wrong.

The C875 records to .ts files – whatever media thespian will recognise this format and play for review without problems; and most editing programs will be able to handle it natively. I’ve been told that iMovie does not recognise .ts files, but you can convert them in quicktime and import the results into iMovie for editing.

An example of the output files for an hour of recording every bit follows:



The filenames seem to follow the naming convention yyyymmddhhmmss and then keeps the start time of the originating recording for all subsequent files. This timestamp does not seem to come from the camera. As information technology’southward on a FAT formatted card, the file size limit is about 4Gb, which is where the file splits occur.

On playback, in that location is a ~0.3s freeze between files when stitched together in the called editing software; Obviously this is not perfect, only far better than the 1-3s pause introduced when with a transmission switch off/on in photographic camera, and the bear upon can be minimised by transition direction in editing.

The format of the files may mean that y’all manage to get over xxx minutes within the starting time file.

Other details:

  • Recording lag on pressing hardware push button: I tested this by filming a stopwatch and simultaneously trying to get-go the stopwatch and press the C875 record button. At that place seems to be a ~one second lag from pressing the button from recording starting. This shouldn’t pose much of a problem in real life. There seems to be a like delay on stopping the recording.
  • Recording to photographic camera media simultaneously: This can be done, but is non advisable, as when the recording to camera stops / starts there is a noticeable freeze in the video (although the audio seems largely unaffected).
  • Accessing menus during recording: Any use of the menus will break the HDMI feed and the C875 will stop recording. You tin can access / modify different liveview overlays without whatsoever problems though (eg virtual horizon, focus peaking etc.).
  • There is the pick to bypass HDMI audio and take an external audio feed direct to the C875 – I didn’t find a apply for it but YMMV (Your Mileage May Vary).
  • Yous do not need a

    headless HDMI dongle

    for the HDMI output socket. Other gaming recording devices may require this, but not the C875. On my initial build I idea I would demand it and got one to exist prepared, but every bit it did not emulate an audio receiver as well as a Hd screen, when I used it my recordings were silent. I got rid of it (equally you lot can see) and my video and audio streams recorded perfectly.
  • The C875 also gives the opportunity to livestream in conjunction with an external connected computer – I’ve got no need of this only it might be a helpful additional feature if you’re doing live consequence coverage.
  • As mentioned, the C875 is now discontinued and there is a

    4K version

    (which also records 1080p); this is likely to exist meliorate supported but is more expensive (though notwithstanding far cheaper than a Ninja) and I’m not convinced by the form factor, merely if you lot need to get something with a warranty this is your best choice in the Avermedia range.

If you
want to see what the output looks like I’ve

taken an hour of riveting footage

of my phones stopwatch without audio, which consists of a single take with the C875. This created the 2 files mentioned above, which were then very basically stitched together in NCH VideoPad Pro. The file transition signal occurs at effectually the 36:40 time mark on the stopwatch.
