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)

 

 

SPECIAL DASHCAM CARDS

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 dashcams...here'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%!

RetroTech: VHD - The 3rd Disc

In this latest instalment of my series of videos about forgotten formats I'm taking a detailed look at VHD, a largely forgotten pre-recorded videodisc system from the 1980s. If you've seen my 2015 video about RCA's financially disastrous CED you may be surprised to find out VHD used a very similar technology but managed to do it successfully. Watch the video below to find out more. 

VHDs can be imported via eBay

My machine was purchased from a Japanese Auction site - using Jauce.

Really, really interesting video - many thanks for all the time and effort you put into these!
I just love that disc extraction and loading mechanism - I think if I had one of those VHD machines, I'd be tempted to replace the cover with a perspex one so I could watch it in action. Keep up the good work, Mat!

Hi Mat! Thanks for spending days working on this film so i can forget about my flu for 30 minutes. Cheers!

I'm glad you liked it. A few people said it was the best video I've done. Unfortunately it seems a bit heavy for non-subscribers so despite all the effort it will no doubt end up being one of the videos that doesn't get shared much. I could have done with a re-post on a big website for the year I've worked on it to be completely worthwhile, but it's probably a bit long for them to recommend. Regardless, it's done now and can stay on youtube for people to view in the future. By the way, while you're ill, have a look at my twitter account /Techmoan and you'll see a link in a recent comment for a 30min video from 1981 that's well worth a watch.

Good to know you read these comments, Mat. Yes it certainly is one of your best videos - I find the vintage hi-fi/video ones the most interesting - I am amazed at the many formats you have revealed that I had never even heard of, and I thought I was reasonably well clued up! In the VHD one I was most impressed at how you swapped seamlessly between the same frame in the different formats to show the differences in resolution. I bet that took some doing!
I would love to see you look at the various record autochanger mechanisms - I don't know if the original RCA thick spindle ones for their new 7" 45rpm format were ever sold in the UK, but the very first UK singles were made with the large diameter hole before standardising on the smaller one we are familiar with now. It is not widely remembered that the 7" single we all loved years ago was an early format war with Columbia's 12" 33 1/3 rpm long player. The RCA autochanger tried to be fast enough that listeners wouldn't notice the break as the records were frequently changed as they needed to be for a piece of classical music on 7" disks.Today's audiophiles would foam at the mouth at the rough handling of the disks. I think I saw a glimpse of an autochanger in one of your videos I saw recently, so I hope this is something you are looking into. Best wishes!

The record player with the changer will be in a future video, that's been two years in the making...however it's going to be used in an unusual way. All will be revealed in a few weeks (hopefully).

I agree with Roland and the other posters. One of the best videos to date. Many thanks Matt

Prior to watching this review I thought it might be a bit anoraky. However, as always, you manage to make the most obscure subjects very interesting. As has been said before, one of your best reviews to date. Many thanks. The puppet sequence was great also.
BTW, do you plan on doing a review of VHD?...Oh, could you try not to speak quite so fast!

Thanks for making another amazing video. I never knew that vinyl could hold data other than audio, this really opened my mind and I have a better appreciation for the technology of yesteryear!

Please keep up the great work!

Fantastic video! I didn't even know this format existed! Would love to add one of these machines to my collection of retro video kit!

While Laserdiscs and VHDs of blockbuster movies can't compare to DVD and Blu-Ray releases, many Japanese anime releases (and other niche products) never made it across the digital divide. Thus, access to these titles is entirely dependent on the goodwill of collectors and enthusiasts who can get the old players working and are willing to transcribe these releases into digital form.

While there's quite a lot of forgettable anime on the analog side of the divide, some good titles are stranded there as well. Sometimes, a title's commercial potential was insufficient to justify the expense of remastering to digital; sometimes, the ownership rights were inextricably tangled as a result of company consolidations and bankruptcies; and sometimes, the original film master was lost.

Thanks for this marvelous video about the second place finisher in a three-horse rate that ultimately had no winner. Working VHD setups are very hard to find outside of Japan.
