Video Recording Times

Published by at 6:07 am under General

I know that this is a photography blog, but the line between still photos and video is blurring on the hardware side. Look at the Canon 7D for example. Beautiful dSLR, with 18 megapixels and 8 frames per second. It also has a fantastic reputation for its video capability. Only drawbacks are focusing while in action video sequences, and its sound capabilities.

The question many have is, “How much video recording time do I get on an SD or SDHC memory card?”

Here is a bit of a table for the new AVCHD format, at 24 Mbps, which is the high end of the AVCHD standard. (I always take my photos and my video in highest resolution. You can always downsize, but upsizing can get ugly)

This is at 1920 x 1080 Full HD Recording, according to the Canon site.

64 GB = 5 hours 55 minutes
32 GB = 2 hours 55 minutes
16 GB = 1 hour 25 minutes
8 GB = 40 minutes
4 GB = 20 minutes

The same chart at the slightly lower 17 Mbps yields this … (still at 1920 x 1080)

64 GB = 8 hours 20 minutes
32 GB = 4 hours 10 minutes
16 GB = 2 hours 5 minutes
8 GB = 1 hour
4 GB = 30 minutes
