Canon 5D Mark IV: Memory Cards | Video Tutorial


Hello, Izzy here. This is one of the questions that I found
about the EOS 5D Mark IV. If this video helps you out remember to hit
us up with a like button underneath and as always, subscribe
to our channel for future unboxing sessions and tutorials such as this and visit
Digital Goja showrooms when in Miami. what kind of memory card should I use? Well remember, this camera has two slots. You have 1 for SD and 1 for compact flash. Now, Canon recommends for your video
especially if you’re recording 4k that you use a UDMA 7 card notice that
this one is one, again, it can be any manufacturer this one just happens to be
a Lexar and notice that it’s 128 GB but the important thing is is the read/write
speed this guy is 1066x because it reads and writes at higher speeds of a
hundred megabytes per second that’s what’s needed to be able to record 4k
video and that’s what’s recommended to use for this camera for your 4k video is
to use a CF card you can also use the SD XE cards now they state that it’s only
recommended to use the UHS-1 that’s the one that is basically recommended for it. This one happens to be a UHS-II when I
have the capability of being able to record on this camera cause right now I
can’t I will try this out and see if it slows it down or not because this one
happens to be faster again there’s that 150 MB/s per second read
write speed so I need to be able to try it out and see if maybe we might be able
to also work with SD for video but for now stick with the faster CF cards for
your video recording.

  1. "Image files can be written to a CompactFlash (UDMA 7) and/or a SD/SDHC/SDXC (UHS-I) memory card.
    Files can be written to both cards simultaneously (for redundancy) or sequentially (for increased capacity).

    Note that, for high demand applications including 4k video recording, Canon is recommending UDMA 7 CF cards with minimum sustained write speeds of 100Mbs or faster.
    Alternatively, UHS-I (not II) SD cards rated speed class 3 or higher are suggested.
    Complicating this selection is that the minimum write speed is not necessarily the number printed on the card and may not even be specified.
    Also note that, when SDXC cards or CF cards with at least 256 GB of capacity are used, the 5D IV switches over to XFAT file system and files are no longer limited to 4GB in size.
    Fast high capacity memory cards are not inexpensive, but alternative fast memory card formats such as CFast are not inexpensive either."

  2. Does anyone have more info on this???
    "Alternatively, UHS-I (not II) SD cards rated speed class 3 or higher are suggested."

  3. Mkiv manual says that the camera is not compatible with USH-II SDHC/SDXC cards. It's only compatible with USH-I SD cards.

  4. Are the SD and CF cards ready to use in the 5Div or do they have to be formatted first? And, there's something confusing I read about, you should not format in the camera but format ExFat onto the cards via the computer otherwise there'll be too many separate folders set up. Can you kindly clarify what your recommended procedure is for 4K recording on both CF and SD cards? Thank you.

  5. Just curious, does the lexar sdxc 1000x UHS II card works on canon 5d iv? I want to purchase the cards, but i am afraid of being incompatible. does it slow down? Thank you

  6. Misleading video, Lexar sdxc 150mb/s 1000x uhs ii u3 does NOT work on 5dm4. What a mistake that I ordered it on amazon. uhs 1 u3 is the proper sd card, i use sandisk extreme and it works alright for 4k vids without problem

  7. JUst saw an AD for WIX……for the 100000th time, who here HATES WIX, and their stupid ADs??????
    besides that, great video.

  8. I HAVE A PROBLEM WITH MY COMPACT FLASH CARD. I HAVE CANON 5D MARK IV CAMERA, I WAS ABLE TO FORMAT MY CF ON COMPUTER BUT STILL, IT IS SHOWING CARD CANNOT BE ACCESSED, REINSERT / CHANGE CARD IF I USE IN CAMERA, PLEASE HELP!

  9. The video is misleading. The SD card recommended in this video DOES NOT work for 4K video recording on the Canon 5D Mark4.
    I found out the hard way.
    In the fine print on the back of the package it says, the read speed is 150 mbs but the write speed is only 80 mbs, but 90 mbs are required for 4K video recording.
    I got the San Disk extreme pro instead with 90 mbs write speed and it works flawless.
