What length of movie do you get on 16GB and 32GB Memory sticks used in Alpha A77 camera
Let's see if my maths is up to this - if not, I'm sure someone will tell us! It will depend on the recording mode.
At the highest AVCHD setting of 50p the recording rate is 28 Mbps which equates to 3.5 MB/s, so it will take 287 seconds to use 1GB = 4.8 minutes per GB.
At a MP4 (1440 X 1080) the recording rate is 12 Mbps which equates to 1.5 MB/s, so it will take 667 seconds to use 1 GB = 11 minutes per GB.
So at the highest settings a 16GB MS would record about 76.8 minutes and a 32 GB MS twice that = 153.6 minutes.
At the MP4 recording rates this would be 176 minutes and 352 minutes respectively.
With the A77 you have a choice of recording rates - 3Mbps, 12Mbps, 17Mbps, 24Mbps & 28Mbps.
I hope that gives you a rough idea???? I'm sure it is in the manual somewhere but it won't download at the moment.
