card capacity at 60p
 

I've read that an 8gb card holds about 25 minutes of footage, but what about if I'm shooting at 720p60? Does the datarate change, or is it the same?

Thanks. :)

Card capacity depends directly on bitrate used, not fps. Therefore, for S&Q (overcranked) 60p it will indeed be lower, but for the "normal" speed 720/60p at 35 Mbps it's the same as for all other HQ modes.
