Record Times for SD (IMX 50mbps)
Hello,
I am a little confused about record times for shooting SD in the IMX 50 mbps format. The Nano user manual has record time listed by bitrate. So 50 mbps has a certain time but does 50mbps HD equal 50mbps SD in terms of record time? I guess I am expecting the SD record times to be much longer or I missed it in the documentation. Thanks in advance for the clarification. |

50 Mbps is 50 Mbps regardless of the original definition. It saves 50 megabits per second. Not mbps, by the way, but Mbps. 50 mbps would be just 50 millibits per second. 50 Mb = 50,000,000 bits. 50 mb = 0.05 bits.
1 second of image data is compressed to 50 Mb, no matter what size that data was originally. |

Thanks. I was thinking frame size factored in but it is clear now.
