Canon 5D Mark IV stops recording at 30minutes, will not rollover to new file.

[Sub7th]

Hey all,
My 5D IV keeps stopping at 30 minutes instead of rolling over to a new file.
The card is not full, and doesn't seem to be corrupted, it is a 256GB Sandisk Extreme Pro, 170mb/s
I also format my cards before each new project, so it was formatted (internally) this morning.

I'm recording 1080 all-i at 30fps, using .mov.

Not sure what's going on or if I am doing something wrong / missing a setting.
I haven't had this issue with he camera until yesterday.
Any ideas?

I think the 5D IV is limited to 30 minutes max recording.   One workaround is to use an external recorder (see page 388 of the user manual which has a special setting to enable for allowing longer output over HDMI beyond 30 minutes).

@Sub7th,

Ricky hit it on the head.  The 5D4 will only record for up to 30 min.  After the recording stops, you should be able to start filming a new movie file again.  As long as the camera is not overheating, has power and space on its memory card, a new file should be generated.
