Kbit vs kbit

8 bits to a Byte is the basic math.

Craig,

I get the basic math its the K vs k that has me questioning myself. If I am setting this up in Compressor I can set kbits/s so I am assuming if they want 3000 Kbits/s I can set up 30000 kbits/s… yes?

Craig,

Just want to make sure I am on the right path. Kbit is a decimal expression (1000 bytes) and kbit is binary (1024 bytes) so if they are looking for 3000 Kbits/s I can go 3072 kbit/s… ?

And can anyone weigh in on the non overt nature of Compressor regarding doing CBR h.264 files. Do I set up as Download to not get VBR?

kbits and Kbits are the same.
Kb and KB can be different though. b is bit and B is Byte

I see where the issue is now.
binary vs decimal.
The program I linked to uses
KiB for binary and KB for decimal

I believe the assumption is binary for data rates. That’s not the case with “sizes.”

but look at this too.
