R5 tethering to Capture 1 - in middle of shoot starts writing JPG's instead of RAW files

I'm editing a shoot that was shot tethered and in the middle of a setup, the files are being recorded as jpg's instead of RAWs! 

Shooting solo, no assistant or DT, just me and subject, lifestyle people photography at an artist studio. Canon R5, Tether Tools cable, connected to 2023 16" MacBook Pro M2 Max - loaded. Ventura 13.5, C1 23 Pro. I was having some issues with losing connection during the shoot (I need to buy an Area 51 cable), but, from the metadata, there were 19 seconds between the last shot captured as a RAW and the first shot captured as JPG. To me, that indicates that, if there was a gap in shooting, there was maybe enough time to unplug the tether cable and switch the camera off and back on again, but not to do a C1 restart or really mess with the Tether setting's in C1 and accidentally switch the Capture Type from RAW to JPG. Additionally, the minimal change in the subjects pose also indicates there was minimal "fussing" with the computer or camera in those 19 seconds.

With the Canon R5, I often shoot straight to card and even when shooting tethered and on tripod, I'll often go off tripod and untether (especially if shooting without an assistant or DT to manage cables and laptop) and shoot to card. That means even when shooting tethered I've got the following setup in camera (when tethered, files only being recorded to computer).  I'm shooting RAW's to the CF Express card and large Jpgs to the SD card as backup. In the camera menu, in the Wrench setting, I have Record func+card/folder sel. to record photos separately (I can get into more detail on that if it's something that could be an issue here). In the past I didn't shoot a backup to the SD slot as I don't like the fact it can slow the camera down and I shoot fast moving lifestyle, but after an assistant nagged me about it, I recently started recording a large JPG backup. 

Anyone else had this issue?

Thoughts on what might have happened?

How to prevent this from happening again?

Thanks!

Greetings,

What FW are you running?  There is only one way I can think of where this might happen.  If Pixel shift gets activated, the camera can revert to JPEG.  After re-reading your post, you mentioned "large jpegs".  I wonder if its pixel shift?

FW 1.8.1 

I assume you mean IBIS High resolution shot? No, that is disabled in both cameras and there's no way in C1 to change that setting so it wouldn't have happened on the computer end of the work chain. 

After a texting with a DT, he thinks the menu setting Wrench> Record func+card/folder sel is implicated, though it's hard to get into details on a text message. I'm thinking of going back to just shooting, at least tethered, with just the CF Express card in camera.

Greetings,

Yes.  I was referring to IBIS High Res Shooting.  😃

I agree the change is coming from the camera and not C1.

Are you using custom folders or naming conventions?  If so, then I agree that would be another possible avenue for the change.

No special folders or namings, that's all done post shoot. 

Interesting that you also think the camera rather than C1. I've already pulled the SD card from slot 2, next chance I get to run a test, I'm going to see if I can replicate the problem, but that's where I'm honing in on the issue occurring.  

Thanks!
