Clear SD card based on storage capacity.

[Excalibur20]

I'm sure this has probably been mentioned somewhere and I haven't seen it given how many people are looking to set up their GoPros as dashcams (myself included), but I was wondering if there was a way to clear the SD card only after it reaches a certain capacity. This would allow for a looping mode similar to dedicated dashcams, where the camera records videos of set length, stops and starts continuously until full and then overwrites the oldest files. I can set the camera to stop and start again using the block coding, but there doesn't seem to be a way to clear the SD card when it gets full. My current workaround is to clear it after a certain number of start/stop cycles. Here I have the partial code for what I'm trying to do:

The idea is that after 30 minutes, the camera starts a new file and it does that 4 times before clearing half the card to make more room. Ideally it would do that indefinitely until the card is full, and only then wipe half the card. Thanks for any help.

Why not just use Clear 128GB before your Exit? Clear will only remove up the half the SD Card, and only the oldest files.

Also on HERO12 and HERO13 you have the system variable 'f' for how full the SD card is.

Remaining space on SD card in GB (or -1.0 for no SD) - >fValueCMD >f4 - more than 4GB left e.g. <f4"SD card warning"

I did some more reading and found the command language page, I just didn't know how to implement that into the blocky code before. I have a Hero 10 and the page says that conditional commands are supported, so I changed the code to use the 'f' command:

The problem I'm having now is the camera prints "SD full: clearing" every time the command runs, even when the card is completely empty. From what I understand, the '>' operator represents an if statement that only executes if the card has more than 60 GB usage. The '+' between the clear command and the text output should put both within that if statement if I understand correctly. As for clearing before the exit, wouldn't that only work if the camera stops recording and exits the program before the card fills up? If I wanted to keep clearing space as I'm recording, wouldn't I need to do that within the program?

HERO10 is not supporting the newer 'f' variable (H12 & 13 only.)

According to the website, Hero10 should work.

The website is wrong (I will update). It was only added to HERO12 and 13 in December 2024. See https://gopro.github.io/labs/control/notes/
