EOS R1 w/CF Express Card says "Number of Clips at Maximum"

[JBradlley]

I shoot still and video all day long every day. I went to the r1 from an r3 in which I never once had this issue. I use 512gb CF Express cards and less than 200 gb used I get a message in my viewfinder stating "number of clips in card 1 and card 2 already at maximum"....and will NOT allow me to video any more.  It will however allow stills.  My camera is set up to record both the stills and video to each card so I have an exact back up.  It's very frustrating to not be able to use the entire 512 gb.  No one has been able to help with this issue.  Hopefully someone on here can.  Thanks in advance..

If the message says that the maximum number of files is at the maximum, then storage space probably isn’t the problem.  How many video clip files do you have in the current folder.  You could be limited to 99.

Waddizzle is correct.  The total number of clips is actually 999.
