A:Answer Bit of a tricky question but in loose terms the front-facing camera, which records at a constant 1080p @60 fps, will fill up cards at the below rate:
8GB MicroSD = 60 minutes of recording
16GB MicroSD = 120 minutes of recording
32GB MicroSD = 240 minutes of recording
64GB MicroSD = 480 minutes of recording
128GB MicroSD = 960 minutes of recording
However, this doesn't necessarily mean you will get 960 minutes of HD video before it starts looping. You can also have the camera create low-res AND hi-res duplicate copies of each file for ease of use so your mileage will vary based on how you set it up, that is your HD mileage will vary I should say. PLUS, if you get the rear-facing camera it records at 720P resolution so smaller files but still it is taking up the same sd card so once again your time overall with 1080P video will vary before files (which are not tagged as keepers) start getting written over.
Here is the user manual so you can better understand, good luck, I enjoy mine with rear-facing camera.

Oh, I should mention you can record without audio so that MAY create smaller file sizes so possible more than 960 minutes of video...I think, lol. OR just forget about anything you don't want to save and let 'er rip :) and tag the ones you want to keep and they will never get written over until you copy them off. Rick.
