I have a Canon 7D (original model). I have a 16GB and 64GB CF Card formatted in FAT32 format. When I attempt to record a movie, I see that the maximum allowed time is 29:59, per US import restrictions. However, I’m finding that I can only record around 12 minutes of actual footage before the camera ends the recording. Looking on disk, I see this is near the 4GB limit of a 32-bit integer. I don’t recall if this is a limitation of the FAT32 file system or not off the top of my head. In any event, is there a way I can get my camera to record more than 12 minutes of video?
Would another file system format solve the problem? If so which ones work with the camera? (NTFS?) And if there are other formats that don’t show this symptom, how can I format the card using macOS Catalina (10.15)?
There is an alternative solution, which is to side-load the Magic Lantern firmware. I believe the process is:
No warranties implied or given. ML stays on the SD card, so if you swap the card out I believe you can run the stock firmware.

The maximum file size on FAT32 is 4GB-1. I'm not familiar with the original 7D (I have a 7D II), but unless the firmware is programmed to record to multiple files, switching to a new file automatically when you hit the 4GB-1 limit, that's going to be your limit. Perhaps recording in one of the lower resolutions will allow you to go longer time-wise, but the file size limitation is still there.
Due to the limitations of firmware, it's unlikely that your camera will understand any alternative file systems. I would think that, if it did, it would give you the option of which to use when you select "Format card". Maybe some really high end ones can support multiple file system types, or maybe just to the extent that ExFAT is backwards-compatible with FAT32 (which is not a lot)...
