Hi,

I am currently doing some research into video codecs and I need to know how to work out the bit-rate of the data stream for a given resolution and frame-rate.

Just taking MPEG-1 as an example. With a resolution of 352 x 240 at 30 frames per second, how do you work it out for it to be about 1.5 Mbit/s?

I’m not looking for the exact formula but I need a pseudo-formula or even just an idea of how the figures are caculated together to get the result.

Any help would be greatly appeciated. Thanks very much in advance.

Regards,
Wai Shing
