Re: 5D Mark IV video automatically stopped recording on fast SD cards

Does this actually work? Haven't tried it but I am also experiencing the same thing. Any other solutions you came up with? Thanks!

Re: 5D Mark IV video automatically stopped recording on fast SD cards

I generally just try to stay with shooting video on CF cards... with SD only as backup because it's so inconsistent. If I do have to use SD, I'd dial back the video to IPB instead of ALL-I. Not ideal I know...

 

I and other shooters have slowly been moving towards Sony and Panasonic in recent years for video shooting. Canon doesn't seem to care about us DSLR video shooters. Smiley Sad

Re: 5D Mark IV video automatically stopped recording on fast SD cards

Hello alvarez8314, 

 

It appears that card may meet the specifications however, it's a microSD card within an adapter and that could possibly be the cause of the issue. We suggest trying a standard full size SDHC/ SDXC card in your camera to see if the same issue arises.

Thank you, Tim!! Every time we advise users not to use micro-SD cards in their cameras, somebody tries to shout us down, claiming that Canon thinks micro-SD cards are just fine.

Re: 5D Mark IV video automatically stopped recording on fast SD cards

In my original post, I never said I ever used microSD cards. I've always only used full sized SDXC cards that were rated at high speeds but have had the video stop recording on all of them at some point. Again the most annoying thing is it seems to happen randomly. If we know what the pattern or specific settings that would help a little bit... but most poeple I know shooting with a 5D4 just avoids the SD slot for any video shooting at this point out of fear of it stopping and screwing us. Just stick with the CF cards...

Hi there!

 

You want to make sure your SD card has a sustained write speed that meets or exceeds the read/write specification for the quality you want to record. In the case of 4K video on the EOS 5D Mark IV, the card has to be able to read and write consistently (not burst) at 90MB per second or faster. Many cards will achieve burst rate, but not sustained rate, and this will cause the process to fail. 

 

You can look at our knowledge base article on the speed class requirements HERE

 

We've found that UDMA 7 100 MB per second or faster CF cards tend to be easier to source. 

 

If you need further assistance, we invite you to reach out to our US-based technical support team at 1-800-OK-CANON (800-652-2666) for one-on-one troubleshooting! 


I suspect that Stephen’s point about sustained write speed probably explains why SD cards may stop recording video, especially 4K video.  Most write speed specifications are actually a maximum burst speed, not a sustained speed.  The CF memory cards are generally capable of faster sustained write speeds than most SD cards.  

 

Out of the cards that were in the image that you posted, I have had issues with Sony and Transcend memory cards and thumb drives, but never with Sandisk.  In fact, I use that very same Sandisk 64 GB SD card in my cameras.  B&H includes it in a kit with a 64GB CF card.  But, I am not trying to record 4K video with them.

Re: 5D Mark IV video automatically stopped recording on fast SD cards

This thread ended abruptly, did someone find a permanent solution or answer? I'm having the same issue and I am a bit disappointed to say the least. Video is my main business and I bought this camera to shoot 4k video. Never mind the fact that it's cropped, but this issue is frustrating. I've used SDXC 95mbps and CF cards with even faster speeds, and still encountered the same random problem. How is it possible that I can record for 30 min in 4k on a card and then do a low-level format on that same card and/or use an identical type of card and try to shoot 4k again and the video stops after 7 seconds? I may end up calling support for 1-on-1 or sending it in, but seeing that I'm not the only one with the issue I figure Canon may have been proactive by this point and at least admit that they are beginning to look at the issue. Anyone out there know what's going on? Thanks in advance for the community of support.

Re: 5D Mark IV video automatically stopped recording on fast SD cards

Hey Jimmerpage. Thanks for contributing helpful information. I'm not the most savvy with this camera, but I know how to look around, and even in the manual of the 5D Mark IV i can't find a single word about color "profile" or "cinestyle". I'm hoping your trick will help save me. Can you point me in the right direction to adjust the color profile setting? Thanks in advance for your help!

Re: 5D Mark IV video automatically stopped recording on fast SD cards

Oh wow, you're getting this problem even with fast CF cards? 

 

I've only ever gotten this problem with SD cards so my solution is to just avoid them and only stick with CF when shooting video. 

I also have been slowly moving over for Sony for video and especially when 4K is needed. At least with the adapters we can still keep using all of our Canon lenses. 

 

We just continue to wait until when or IF Canon ever decides to be serious with DSLR video... in the mean time Sony and Panasonic are happy to make it work for us and at least we can keep using Canon glass.
