H.264 encoding on the graphics card of rudi - 29 May 2008 09:58:00
As Heise reported yesterday evening, presented the company ETI just a software application, the H.264 export through the use of the graphics card much faster. A conversion of HDV after H.264 is given to a Quadro graphics card with 46 frames per second running. Indeed, this still says nothing about the quality achieved, as with lean parameters can be synonymous or H.264 encode pretty quickly. It is worth noting however, that this program directly as a plugin for Premiere will appear. We ask ourselves, of course, why something is not a codec on the market and look forward to the results of market-ready product in the autumn.

You see, Mr. Wunderlich - it happened more characters and wonder.

You read it here first.

As a codec (which is already there, which is the H.264?)? Or as a driver? Or as a turnkey encoder / decoder? Or in NLEs integrated? Or hardware?

But only in very low resolution or legally fixed processors (Quad ~ 3GHz). On slow processors take even the simple conversion ne half eternity.
If everything about the graphics card goes, the zweitranging processor and the GPU, thanks to its' pipeline 'architecture better suited to relatively simple arithmetic operations quickly processed than the CPU.

@ Daigoro

Well, some people in this editorial are any more questions than it answers have ... perhaps they should better go into the auditorium.
The theme is in the past epic Width been answered.
Sometimes synonymous helps the editorial team's search.
Because synonymous here implied question was answered more than exhaustive.
Furthermore, since accelerator .... maybe you should have such a function even clear, it would not to such issues.

Well, is particularly meaningful, the name does not. I would now marketing name for ne held.
Everything better, faster, more beautiful.

In principle, but it's seems to be working, as in the last post relating to suspected:
http://elementaltechnologies.com/how_it_works.php
http://elementaltechnologies.com/pdfs/Elemental_RapiHD_Premiere_Pro_overview.pdf
(super technical explanation: D)

A 'hack' the calculations instead of the CPU of the stream processors of the GPU allows execute. Instead of "Quad Core" .. "128 Core".

When the now synonymous nor the jump in the consumer area and creates not only QuadroFX cards and PP, one could almost recommend AVHCD yes: D



Antwort von WoWu:

The function is very subdued declared but surely would have in the Constitution of the thread helped.
The author would then have to recognize that the Accelerator nothing s.Hut with the codecs but that has only very specific parts of the computational work of him running. So far no complete monolithic system but also allows each application provider, nor its unique selling points to present.
But the topic I have already almost a year ago described as ... So after reading help. And with low resolutions ... parameter or the stomach .. or something like that has nothing at all, are not synonymous in the approach to do .... The reference to the device is very laudable, but the rest .....
