G9 new trick (compared to earlier models) ?

I was pleasantly surprised to see that that G9 silently closes the 4G file and continues without missing a beat in a new file! Awesome.

And I wonder... did my old G7 know how to do that? I doubt it, but I may not know, since the G7 had an anti-aliasing filter and therefore would reach the time limit before reaching 4GB file size, at least that's what I remember.

My G85 and LX10 both do this for 1080p. Both those two cameras can record longer than 30 minutes, so it may not be a fair comparison, but it shows Panasonic did do this in older cameras. The G85 won't split the file if it is recording 4K and you have a 64GB SD-XC card (the LX10 can't record more than about 10 minutes of 4K).

So I imagine that the G9 probably also would not split the file at the 4GB limit if you have a SD-XC card and record 4K instead of 1080p. Given the amount of data 4K produces, I imagine if you have a smaller card than 64GB, the card will fill up first.

Thanks Michael.  That makes sense.  The 32GB cards write FAT32 format, thus the 4GB limit on files.  And the 64GB or larger Extra Capacity SD cards write larger than 4GB files.

For long video files that is the case, 32GB will not hold much in 4K.  A lot of the video shooters using the G9 and GH5 use 128GB SD cards when they shoot long videos.  And some use the 2nd card slot for the overflow.
