Title: SD card size?
Post by: jasonfish on September 04, 2017, 11:47:38 AM

I've read up on SD speeds and have narrowed down my choices. But how big are the files saved to the card? How much space is needed for, say, one 8 second clip at max resolution? Max frame rate? Should I be looking for 8gb cards? 64? 128?

The biggest size file I've made sofar, using the full 4s buffer of my camera and one of the high framerates is about 300Mb.
But normally you mark in/out just the event you care about ad get a few seconds, or fraction of a second realtime. It also takes ages to write the full buffer.
So typically files end up 30-130Mb.
