Does the plugin is supossed to work with radeon 4850 ?

I installed the plug-in and I can see it and select it on adobe premiere,but I did'n see any performance at all. 

My CPU is used instead of the cpu card, any ideas ?

There were lots of questions raised in the first thread for this Adobe Plug-in. Listed below are the answers. We are also working on a more complete FAQ as well that will soon be posted.

*******************************************************

Question: Has this been tested yet for FirePro cards such as the 3750 or 5700?  Definitely could use this in a DCC workflow.

Answer: It does work with the limited testing that we have done so far. It has only been tested with a limited set of encodings. We have not fully qualified this yet with FirePro series.

Question: Also is this using OpenCL for the acceleration via Stream?

      Answer:  This application does not yet use Open CL. It is based on the AMD Compute Abstraction Layer (CAL) interface.

Question:   Will this plug-in work with intel cpus in the near future?

       Answer: We have no plans for porting this to non-AMD platforms at this time.

Question: Any chance the MSI will be a bit less restrictive and permit Windows 7 users to test this out?  I just got a "Needs Vista SP1" error!

Answer: Yes, as we continue to test on additional operating systems, this restriction will be lifted.

Question : Any idea if this plugin will also accelerate the editing process? Meaning will it be able to play AVCHD/H.264 footage in realtime? Assuming you have the correct hardware to follow... (quad core AMD, 8GB ram, HD4870...)

Answer: Currently only the Encoder Plug-in is available. We will consider adding decoder plug-ins in the future.

      Question: Pretty much any recent graphics card will handle this no problem. One observation though, when I tested Premiere Pro CS4 in Windows 7 playback was really choppy.

Answer: Please check the Adobe Premiere Pro technical help on this issue and the response in this forum's first topic under #6 regarding playback issues.

Please install the ATI Stream Encoder Plug-in for Adobe Premiere Pro CS4 and evaluate it in the course of your video editing projects. We are looking for feedback and recommendations to help us make future versions even better. We want to make modifications as close to real-time as possible, so please keep the feedback coming.

Download the plug-in here. Answering a short survey is required before downloading.
