Canon EOS R5 Mark II Playback Bug with Video Repro - Any Canon Moderators Reading This?

[herein2021]

I have now been dealing with this very annoying footage playback bug with my Canon R5II since I have owned it. I have asked on various forums, plenty of people say they have it too, I also sent screenshots to CPS and they said for me to send it in; it is just annoying enough to be a problem but not worth sending it in and losing my camera for weeks especially since it probably wouldn't get fixed since it's a FW problem not a HW problem.

So, at this point I am just curious to see if anyone on this forum has the same problem and hoping there is some slim chance a Canon moderator might see this, repro it, and notify the FW makers that their FW has another bug that so far doesn't seem to be addressed even in the latest 1.1.0 FW.

So, the problem that I have with playing back footage is twofold and I believe anyone can repro this with their R5II as well.

1. When I take a mixture of pictures and videos with the R5II, it does not keep them in chronological order when I hit the playback button. So, for example, if I take 1 picture, then 1 video, then 1 picture, then 1 video, I should be able to hit the playback button and see picture | video | picture | video.

In the R5 and R7 that's exactly what I see when I hit playback. With the R5II when I hit the playback button, I see video | video | picture | picture. The R5II groups all of the videos together and all of the pictures together. This is annoying enough, but as the clip counts get into 50+ and the image counts do the same, it leads into problem 2.

2. At some point after taking a lot of video clips and pictures, the camera stops showing the last picture or video taken. When I hit the playback button it gets stuck only showing the video group or the images group. At this point, I am now standing in front of the client scrolling through tons of video clips trying to show them their last picture taken or sometimes it gets stuck on the images group and I have to try to scroll through all of them then get to the videos then scroll through all of them as well just to try to show the last image or video taken....very frustrating.

The only workaround that I have found so far is to set image search conditions. If I set the image search conditions to just photos, I can then find the last image that was taken, or if I set the images search conditions to just video I can find the last video filmed. But then to switch back and forth I am back to fiddling, usually with sweaty hands, in the middle of a shoot....not ideal at all.

I forgot to mention in the video that even FW version 1.0.3 had the same bug, prior to rolling back to FW 1.0.1 I tested the playback behavior and it was the same.

Here is the repro video:

Actually I think the playback bug I experienced was due to using slower SDHC cards (30MB/sec). It seems the camera was still writing the 50MB file when I pressed playback. Will check this weekend.

That's a valid point. I have seen cameras that play back the last saved image on a card. If you shoot a lot of images at high frame rates, the camera will buffer images if the card is too slow. When you hit the playback button the camera reads the last image on the card, it might not be the last one in the buffer, and while you look at the image from the card, the camera then writes another image after the one you have displayed.

I seriously suggest updating to higher performance cards for your EOS R5 Mark II. I would look to get cards that are UHS-II type and support at least V60 and ideal V90 speeds.

When I saw the bug it was not a card issue, I always playback from the CFE card and I mostly film people with fill flash so no more than one picture every few seconds at most. 

But like I said, I think it was just with FW 1.0 I don't remember seeing it since then. There was a lot going on then, the green screen issue, playback problems, etc. I feel like I haven't seen this one since then.
