Hi

I'm a bit confusing about EX 1's Bit Rate. The compressor says that it is 35 Mb/s VBR but when I take the files to Final Cut Pro it says that Data Rate is 4,3 MB/sec. Or is Bit Rate same as Data Rate? Is the other Bytes and other Bits or something?

Thanks

Mikko

Yes - "b" is bits and "B" is bytes. 35 Mb/s = (35/8) MB/s = 4.375 MB/s.

FCP's Data Rate value should include the Audio data as well as Video data, which I'd think ought to make the overall Data Rate closer to 4.6 MB/s... *shrug*

Okay, thanks a lot Robert. It's nice how the Marketing people tells those things in Bits so it looks bigger and finer. :)

Megabits vs. Megabytes- forever confusing.

Indeed it is confusing, particularly now . . . Ah, but from my mainframe system days, a bit is short for binary digit (an on or off). It takes a string of bits to represnet numbers larger than 1, just like it takes combination of digits used for numbers larger than 9 in our decimal numbering. So, bits in strings of eight are called bytes, each of which typically represents a single character of data. Bytes, as a term, is used less and less, just like nibbles (half a byte, or 4 bits).

Okay Tom. I just needed to read that about five times to understand everything with my english. :)

So, the number required to factor bytes using Shor's algorithm is still polynomial, and thought to be between L and L2, where L is the number of bits in the number to be factored; error correction algorithms would inflate this figure by an additional factor of L. For a 1000-bit number, this implies a need about 104 qubits without error correction. Just kidding. :)

But all the crew wants to know is how many bites per minute the lunch break is.

"But all the crew wants to know is how many bites per minute the lunch break is."

If the quantity of free pizza and the voracity quotient of the crew are known constants, then I think a pretty easy formula could be constructed. Don't forget to factor in whether they're getting Dew or Red Bull.

[Clint Fleckenstein] "Don't forget to factor in whether they're getting Dew or Red Bull. "

So depending on quantity of Dew or Bull it's Variable Bite Rate generally increasing against the rate and quantity ingested?

What's the deep dish/thin crust differential?

Deep Dish is much harder to decode. The trays to hold it cost more too.
I've tested both in Final Crunch Pro.
Some say Eatious can handle native crust.
After Snacks slows to a crawl though.
Meaty One Hunger clogs on input.
