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%!

CD Video (not Video CD)

CD Video is a confusing format, not just because of the similarities of its name to Video CD, but also because it's really two formats pretending to be one, and one of those already existed under another name. In this video I attempt to navigate through this confusion to explain what CD Video was and why it’s all but forgotten nowadays.

Also if you're interested, back in 2015 I made a video about Laserdisc:

What a great video - again. Really informative and entertaining! I was aware of VCD (which I recall overlapped with DVDs for a while, but was always the poor relation), and I knew about Laserdiscs, but CDV was really unknown to me.

Trying to think back to the 1980s, and why buying movies on Discs (of any format) didn't appeal to me, and I think it was not only the cost of discs themselves, but that for many people in the UK, the concept of buying and owning movies hadn't yet really caught on. At the time, I believe you could theoretically buy movies on tape, but they were getting on for £100, so you either recorded them off the tv or rented them.
Also, I think that being able to record tv and movies and play rented movies on a VCR was such an enormous improvement over what went before (ie going to the cinema or watching scheduled tv programmes and movies being the only options) that disc-based movies did not seem such a huge advance. We only had smallish screen CRT TVs back then so any improved quality that you could get from a disc was barely worth paying so much for, especially as you couldn't record anything at all on them yourself. So in some ways, a disc-based video player seemed an expensive and retrograde step from a VCR. That's my recollection anyhow.

Having recently got rid of a cupboard full of watched-once DVDs, I think things are going full circle regarding owning a 'hard' copy of a movie - especially as you can now stream in 4K. For some reason, none of the disc-based movie formats give the tactile and engaging satisfaction that vinyl audio discs provide.

A couple of questions, Mat: A few times you referred to the high prices of the various video discs, but didn't give any examples - do you have any price lists from the day to show typically how much a mainstream movie would have costs on a disc back then?

Secondly, that looked to be a very interesting CD player/recorder you were using - looked like it had two decks, and I noticed it mentioned 'RW' on it, so I assume that it could copy CDs? Couldn't spot the manufacturer's name anywhere - I hope you're planning to include that device in a future video?

Unfortunately I don't have any price lists for the time - I do remember the feeling of seeing them and thinking that I couldn't easily afford them through...and at the time I did have a full time job. This is one of those pieces of tech that hasn't been well documented. Record shops didn't generally give out catalogues with prices on them and of course it was pre-internet, so I had nowhere to look for the info.

As far as the CD player goes - that's the subject of the video due out later this week. The people over on Patreon are watching it now - sometimes I re-edit videos for clarity or to make corrections after I get their initial feedback, but I aim for it to be out on Thursday.

Most laserdics I bought were about £20-£25 for a single and £35 for a double disc. Fox discs were always more expensive. This was when VHS was £12 to £15. The 5 inch CD-Video I bought was £4.49

Thanks, Al. Was the quality noticeably better than VHS, on the tv you had at the time, would you say?

February 7, 2018 | Unregistered CommenterRoland

It was very much better than VHS on my 24" B&O 4:3 tv even though NTSC was converted to PAL50 and slightly squashed and PAL discs had faint horizontal lines if the brightness was too high.

what would this be played in in 1982?

It’s a laserdisc. Laserdisc (known in the US as Discovision amongst other names at the time) came out in 1978.

huh. just seemed early for laserdisc. what really through me though was that GM would be using laserdisc for promo videos at that time.
