60D and PNY 32GB Pro Class 10 Chokes on Video

Just received my second copy of this card from Newegg.com and it does the same thing as the first - chokes on video from my 60D (video buffers then stops recording). I am wondering... I am testing it in a fairly dark environment. This forces the ISO to be high - at 3200. Would there be a higher data rate for video in dark environments? Could this exceed the 20mb/s rate of this class 10 card? I know that still photos shot at higher ISO have larger files sizes. Any ideas? Should a class ten such as this work no matter what on a 60D?

I have class 4's from the same manufacturer that handle video just fine, but this supposedly significantly faster card chokes on it.

The one on the left is class 4 and has not buffered once, the one on the right is the new on and I've had 2 copies now that perform the same. Crap!

in file size.

Never heard of PNY

...but Transcend cards have always performed perfectly with Canon DSLRs for video.

Get Transcend.

Re: Never heard of PNY

PNY is one of the top 5 memory manufacturers in the US. They have more memory products on Newegg than the majority of memory manufacturers. Their cards are very highly reviewed. This is why I can't understand why I am either the unluckiest consumer in history, or PNY is lying about what this card can do. It's VERY strange that I have class 4's from the same manufacturer that have no issues recording 1080p/30.

Re: Never heard of PNY

I use PNY, A-Data, Transcend, Sandisk, Lexar and Delkin. I have a couple of 32gb Class 10 cards (Delkin, Transcend) and I notice that they do lag a little bit when recording pics. Haven't tried video yet. I'm hesistant getting the SDXC if Class 10 cards acts this way.

Re: Never heard of PNY

I also have a 60D and I ordered the same PNY 32gb card. Should be here tomorrow or Thursday. When it arrives I will try shooting some video and see if it does the same thing. I have two other PNY cards. An older class 4 8gb and the 4gb class 10 version of the 32gb card and I have not had any problems shooting video with them.

No. It's directed by the frame rate

matter what on a 60D?

1080p is 1920x1080 at 30 frames per second = 91 Megabytes per second. Canon uses MPEG-4, which is 16 to 1 compression, so now the memory card speed needed is: 91 Megabytes divided by 16 = 5.7 Megabytes per second

For the actual calculations… see: http://www.foto-biz.com/Lightroom/Hd-video-and-card-speed

SD Class 4 is all you need.

The one on the left is class 4 and has not buffered once, the one on the right is the new on and I've had 2 copies now that perform the same. Crap!

  1. If they are from the same batch, they should fail in the same way.

  2. Do they format properly? When you connect the cards to your computer, do you see all of the 32Gb, including the free space?

  3. Have you run some kind of chkdsk?

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

PNY replied to my complaint email:

"Thank you for contacting PNY Technical Support.

Sorry to hear about the problem you have with the PNY 32 GB card, some camera are not compatible with Class 10 Cards so please Contact Canon and ask if your camera is capable to run with Class 10 cards or Not.

I apologize for any inconvenience this might have caused."

TOOLS! Of course it's compatible. Anyways - already have a SECOND RMA request with Newegg for a REFUND this time.

No. It's directed by the frame rate

I would have thought the more movement or noise in the footage the higher the bit rate would be, same as with a noisy still image being larger than a clean one.
Are you saying that the 60D uses a fixed bit rate?

If i pan a shot at 1920 x 1080 30fps i sometimes see the fuel gauge on the LCD. As soon as i stop it goes away. This suggests to me that more data is being transferred to the card, which is starting to reach its write speed limit.

I could be wrong and have no real technical expertise so please correct me if im wrong.
Ive looked at you figures but dont really understand them all.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

I thought I perceived that I could trigger the buffers by moving the scene quickly/zooming - and it also seemed like the fail rate was higher while pointed at a dark scene. If the data is constrained to a fixed data rate, the IQ would have to fluxuate. I am still convinced the data rate is not constrained and movement/higher ISO's are more demanding on write speeds of the card.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

Class 10 means 10 MB/s continuous guaranteed, even with a fragmented card. The 20 MB/s is peak speed.
Either way, the camera outputs 6 MB/s.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

Same problem here, got my PNY professional 32GB card from newegg, and the card failed to record 1080P video 50% of the time. BTW are you able to flight off the restocking fee when requesting a refund from newegg?

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

I just requested the second RMA as a refund. I wanted this card to work. If they had the ability to just trade for another product and pay/refund the difference I would. They can kiss my business goodbye if they try to restock me on this one. They are defective returns not elective returns due to dissatisfaction. I told PNY this morning how angry this whole thing has made me.

FYI - Stuck a 4 year old Kingston 2GB in the 60D this morning and it performed better than this card. I think it was made before they even started the classes.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

One way of testing these cards is to do a read write to and form a computer with a large file.
That should at least give an indication of what the card is capable off.

The class rating is a minimum write speed i believe. so although a certain class card should achieve the minimum rating there is nothing to say a lower class card cant be faster.
IME of course.

Yup, my 16GB Transcend works great. I have a 32GB s well, but haven't tested it yet.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

I've heard that PNY Pro cards rated at Class 10 are in fact on par with most other manufacturer's Class 6s. PNY has aggressively priced these cards and placed them in high volume Best Buy. I bought some for recording 720 on a couple of Olympus m4/3 Pens and they work very well.

We use 16 and 32 GB UDMA cards for our 7D video. Although quite pricey, they are a must for commercial work.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

Got my PNY 32GB Class 10 today. Tested it out with some movies with the 60D and it did the same thing for me. However out of 15 times I tried to make a test movie it only stopped 2 or 3 times. Not an issue for me since I will rarely, if eve,r use the camera for movies. But something to be concerned about for sure if you want this card and plan to do a lot of video. I did notice that when I formated the card in the camera that the progress bar moves slow at first and then goes fast. None of my other cards do that but they are smaller capacity cards as well.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

Oh, and one more thing. I just popped the card into my Canon Power Shot SD1400 IS compact camera that also shoots hi-def video and it had no problems at all. Didn't crash at all.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

I have a 32GB PNY card and am experiencing the exact same problems. Coincidentally, I also have the same exact 16GB PNY card and, like yourself, it's working fine.

I've posted more details (ramblings) on my blog here: http://www.jerslife.com/word/digital-cameras-write-speed-on-sdhc-memory-cards

It seems that formatting these cards in the camera will actually make the problem even worse. The camera creates 16kb cluster sizes, while the factory defaults are 32kb. Since the problem is so intermittent, it's difficult to get accurate results.

I've put in a support request to both Canon and Patriot. I have 4 of these 32GB cards and they're currently all useless to me, as I purchased them specifically for video work.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

I returned both PNY cards to Newegg for a refund and purchased a Trasncend 32gb Class 10. I've seen the buffer meter appear once briefly, but have not been able to get it to stop recording (good thing). I'm pretty unimpressed with how PNY handled my technical support request (basically told me it was my fault and the card may not be compatible) which was utter horse poopy. I would return your PNY soon before your return/warranty with the retailer runs out.

Re: 60D and PNY 32GB Pro Class 10 Chokes on Video

For what it's worth, PNY is a company I stay away from.

Bought computer memory of theirs from Best Buy years ago. Came with a rebate. The very next day BB ran an add for the same memory at a reduced price. I took the receipt back and BB gave me the credit. Sent in the receipts to PNY for my rebate and was denied because my new receipt had the date of the credit and the rebate ended the day before. No matter what I said, they basically said Tough Crap.
Not a good company to deal with.
