Cat 9.5 and Stream 1.4 should enhance Cyberlinks editing suites.

What’s New in v1.4-beta

* Significant feature enhancements to Brook+:
o Support for multiple GPUs in a single program.
o Support for 8-bit and 16-bit integer types.
o Interoperability with DirectX API.
o Access to thread-level data sharing.
o Improved support for Microsoft Visual Studio 2008.
* Performance enhancements to the Brook+ runtime:
o Support for memory pinning to optimize data transfers.
o Support for asynchronous stream write requests.
* Additional hardware features exposed in CAL:
o Support for texture sampling (bilinear).
o Support for FETCH4.
* Support for the ATI Radeon HD 4870X2 and 3870X2.
* Support for the ATI FirePro V8700, V7750, V5700 and V3750.

Well SDK 1.4 beta was released a long time ago (couple of months).

Seems they are doing something akin to cuvid here (http://www.fudzilla.com/content/view/13939/34/).


The runtime should enable quicker transcoding with lower CPU loads as the company’s technical manager explained that AMD “unlocked” the video processor in order to enable non-real-time decoding.

sorry yeah. the SDK is half of the equation, Cat 9.5 hotfix is the other part.

Yeah but any test of the second coming of the AVIVO transcoder? I've only seen news about it and I'm curious weather is the same crap as before.

Is there ANY hope that someday Avivo will work and be useful?!
Years after announcement its still vapourware as DNF :(

ATi should outsource this thing, really!
Just step on the CAL libraries and OCL/DXCS drivers.

[chavvdarrr]

could it be hardware problems due to ... something?!
Why bother making & marketing product which for 3+ years never ever worked ?

[Arnold Beckenbauer]

ATi's problem is, that they no equivalent to Nvidia's ETI, so ATi have to do research and development,, but they don't do it. And Nvidia's CUDA encoder is unreachable (High Profile, CABAC etc).
But on the other hand: MSE (MediaShow Espresso) is fast, but it sucks. You cannot set your own bitrates or the target size. It has problems with 1080i50 and 720p50. It converts your audio to DD 2.0, even if the source is DD 5.1 (very clever). Bitrates of the iPhone profile are to high. It's wasted money at the moment.

There is the free MediaCoder, which can use CUDA for encoding (and there are a lot of options), but it violates so many licences, and the CUDA support is currently disabled.

As long as x264 running on a C2D is unreachable for GPU based encoders I fail to see how it's at all relevant :p

About the video artifacts -- could be this (from Cat 9.6 release notes):
On some configurations, video artifacts are no longer visible during playback of
transcoded video files

[Psycho]

Nothing mentioned about such artifacts in the other tests, although they are both on 9.5hotfix:

At least the extremetech review would probably have mentioned it if it popped up in their tests..

[AlexV]

Depends on the encode source.
