What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

I love a good bad idea - and the Sony Ruvi was one of the best

Sometimes you don't realise how far you have come until you look back over your shoulder. While 1998 doesn't feel like ancient history to me, in home video camera terms it was a completely different era. 

Watch the video below to find out about what has to be one of the worst ideas that Sony brought to market, eighteen years ago. 

I've collected the pictures of the inside of the video cart into a zip file. It seemed a shame to just delete them. You can click the image below to download the photos.

I can't find the video you mentioned of the trip to New York. Is it still on here?

It's not really a trip...well not for me anyway. Click here.

Excellent, thanks ! Had absolutely no recollection of that contraption even though I've always had my ear close to the ground when it comes to useless gadgets ;-)

During the video I was looking for the name of Sony's other bad idea to replace the miniDV...and now I wonder whether it wasn't the microDV with some kind of mpeg2 compression that computers weren't really powerful enough to edit at the time, that would have been 2002...yep that's it well I suppose it wasn't that bad after all if it's your favorite camera !

What a bad idea!

Was your minDV footage a lot better? I thought early digital camcorders were quite ropey.

October 26, 2016 | Unregistered Commenteral

It was better - but of course still SD video. However the digital files from a MiniDV camcorder could be copied to a computer, and edited digitally without any degradation, so the end result of an edited MiniDV video could be a lot better than an edited analog video.

I really would like to speak to the designer about this.... what a bummer concept! ;(
Thanks for letting us know, I had NO IDEA! 8 -)

We used to use the other JVC cam u mentioned, for surveillance. And the song TRV range was used in the static vans in the 90's due to its size

Thank you for your amazing research Matt.
I never knew this device even existed. I must confess I am still waiting for the penultimate recording device. There was a time I wondered if people would ever get sockets fitted to their heads and brains so all the stuff they saw could be recorded in some way or another. I was at the time thinking of Audio but who knows if we will all get fitted with some sort of Bluetooth thing ( a bit like the Matrix film ) so we can record and share our experiences.

Good luck with your next venture and thank you for the most informative videos I have ever seen on the web.

I also had one of the JVC DVCam camcorders. I seem to remember mine having an eyepiece and a flip-out monitor. I also remember going though a heck of a time getting the footage on to my PC. Incompatible firewire card, bad drivers, and capture software that just didn't work with the camcorder. Then the tape would eat itself once in a while and the footage would be completely gone.

I don't recall ever seeing the Sony Ruvi camcorder, but that was the time when Sony was churning out many different products, trying to find the next big thing (preferably with a very high margin). In the pro video world, they were selling Digital Betacam, D1, D2 and a pro version of DVCam that wasn't exactly compatible with anyone else's DVCam, along with HD forms of everything. Meanwhile, Panasonic was moving to flash based recorders using a system that looked like a PCMCIA card. I remember seeing all this and just thinking "they don't get it." Eventually Canon and the other DSLR makers got it right.

You must take your Ruvi Video Cartridge to an authorized Sony Dealer and ask for a replacement.

I'm sure the look on the face would be priceless.
