Opitical Thunderbolt cables. On a Thinkpad.

flashes of thunder at mountaintop – large numbers hurled in the clouds…

[Jeremy Garchow] “4 times the pixels do not equal four time the size in ProRes, there’s more math going on than that.”

It’s an algorithm, not magic. I generated this graph with the numbers from Apple’s ProRes specs (because their table happened to paste perfectly into Numbers). Note the data rates are proportional to the number of pixels encoded. If double the pixels yields roughly double the data rate, it stands to reason that quadruple the pixels yields roughly quadruple the data rate.

I’m done now too.

Best,

I seem to remember 440, but I can only find 330.

Yeah, sorry. It’s my bad.

hell no. that was fun, and rather informative. I know a quite a lot more than I did eleven posts ago.

Also, all vbr codecs occasionally spike and sometimes quite substantially. 30 percent on top of the spec average isn’t uncommon.

There it is. 2k@60p is pushing 750Mb/sec (less than 100 MB/sec).

Thanks, I missed that one when I looked earlier.

If ProRes was CBR, meaning every frame got the same bandwidth, then the math would be more equal.

Whatever the case, ProRes is sweet, hope it doesn’t go away, and we all live happily ever after. Fin.

Promise is showing a 200M optical TB cable on a MAC system in thier Booth here, While I am happy that TB is coming to windows I know of over 75 TB devices at the show!

[Steve Connor] “Interesting?”

Hell no. Thunderbolt sucks and won’t do anything to change the CPU market, or fill in any voids.

Keep pipe dreaming!
