Update on ATI AVIVO?

[dattrax]

I've seen some old posts in this forum about the X1??? ATI cards and the AVIVO technology for accellerated h264 encoding. Is anyone using this as a viable encoder?

The reason I ask is I am converting some HD1080P material and it took 18 hours for the first pass using Mainconcept encoder.

The solution is to get either a new CPU (I've an old HT P4 @ 3GHz), which will give some benefit or try a X1950 as a replacement.

The current conclusions from what I have read here is that the AVIVO just does it in software and gets the speed from reduced quality. Is this still a valid statement or have ATI turned on their hardware accelleration?

If anyone has used this recently then I would like to know your opinion.

The format I need is
1080P, 18frame GOP, VBV 1851392, 2 Bframes, CABAC @ 10mbps
so the codec needs to be configurable enough to do this.

Cheers

Jim

In this moment dont exist any encoder that have hardware accell. In theory are posible, but in this moment no encoder are avalible. With Nvidia CUDA (8x00 serie) or Cg will be posible make a encoder with hardware accell. A good example of this is the new Nvida Texture tools.

exactly, Avivo only are a fast software encoder. If you want more speed in your enconder, try other faster encoder options or replace your CPU for example to a Core 2 Duo/Quad or wait for a newer Wolfdale/Yorkfield.

The ATI AVIVO encoder was a baseline-profile encoder only, ie: only CAVLC, no B-frames.

OK, Thanks

Looks like a new CPU then
