Cards for 4K video-5DIV

Cunha — Fri, 10 Nov 2017 15:15:41 GMT

Hi,

I will soon start to shoot 4K video (5DIV).

I know from the camera´s manual the minimum specifications for CF and SD cards to record 4K.

(UDMA 7/100MB/s or UHS-1/Class 3)

Any opinions about CF/SD brands and models with good results from this community? Brands to avoid?

In the past 7 years I´ve been using Sandisk, Lexar and Toshiba, but with moderate speeds. Not fast enough for 4K demands.

Some of my cards are 7 years old. Never had a problem.

Never try 4K video .-) My 5DIV is brand new (1 month).

Thank you very much for your help.

Please, Canon, we REALLY NEED a video-specific board in this forum. People keep raising questions like this, and most of us have NO CLUE, because we don't shoot video. If you're going to make video a feature of your DSLRs (and that genie is obviously out of the bottle), you should be willing to moderate a video-specific conversation. Several of us have made this point for a year or so, but we have been effectively ignored!

I would recommend a UDMA 7 Compact Flash card that supports the VPG-65 specification, or an SD card that supports the V90 specification. UDMA 7 CF cards without the VPG-65 specification, or SD cards without the V90 specification may work but there isn't any guarantee so it would be a matter of trying it out.

Note that manufacturers will typically market the fastest burst write speeds for any particular card. This does not matter for video. You need to look for cards that can sustain a sufficiently high continuous write speed and that's what the VPG-65 and V90 specifications are designed to do for CF and SD cards respectively.

Since SD cards with the new V90 specification were so new, I just looked around for some available options and it does seem like SD cards with the V90 specification are all UHS-II. The 5D Mark IV SD slot is UHS-I. UHS-II cards would work, but would not support all of the rated speed specifications. It isn't clear to me whether or not the V90 specifcation requires a UHS-II slot.

In my opinion it is safer to go for the CF card, but I will note that I have some UHS-I cards that I have used on the 5D Mark IV at 4K 30p. I hope that wasn't too confusing!

The user manual says that we should not use UHS-II cards.

Try asking the people at the place where you bought the camera. Your question should have been asked before you bought the camera.

“What memory card should I use with the camera?”.

Sandisk Extreme Pro CF/64GB (capacity example)
Read: 160 Mb
Write: 150 Mb
VPG-65
UDM7

🙂
Seems like a good option.
Thanks again for your help.

Is that what the people who sold you the camera recommended? A 64GB card is pretty good for shooting stills. However, if you are looking to shoot 4K video, then you want at least 128GB, which will give you just over 30 minutes of recording time.

All of this, and more that you need to know, is covered in more detail in the Instruction Manual.

I wrote "capacity example".
Thanks for the tip; anyway.

"to shoot 4K video, then you want at least 128GB, which will give you just over 30 minutes of recording time."

Lets pretend that I will shoot a 29" minutes video piece.

With a 128Gb card I will have several small files for those 29" minutes?

With a 256 GB card I will have a unique files for those same 29" minutes?

Is there any real (dis)advantage for editing purposes, between a unique files and several files?

Or it is the same, when editing?

Thanks

There is no good way to answer that question. It really depends upon the nature of the edit, and editing software itself.

As a general rule, computers process larger chunks of data than smaller chunks. But, there are exceptions to that, too.

Da Vinci Resolve.

Is it harder to manage 4 smaller files or 1 big file?

Do i need to perform any kind of transcode in any case (1 file vs 4 smaller files)?

Da Vinci Resolve is not a product that I am familiar with. I suggest that you simply exercise common sense, or just simply try it.
