EX1 Bitrate (or data rate?)
Posted by Mikko Kovasiipi on February 26, 2009 at 12:16 pmHi
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

February 26, 2009 at 2:34 pmYes – “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*

February 26, 2009 at 7:43 pmIndeed 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).

February 26, 2009 at 9:05 pmOkay 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. 🙂

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.

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

February 28, 2009 at 1:19 amDeep 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.
