ATI Radeon HD4850 Transcodes Four 1080p Video Files Simultaneously in Real-Time

With advancements in visual-computing technologies on an all-time high, and graphics processing units with immense 3D computational power coming out by the fortnights, consumers benefit the most. In the process of evaluating graphics processors' abilities using the latest 3D games and synthetic 3D benchmark software alone, we are probably missing out on other primary uses of a GPU which when tapped, show just how potent a GPU can be. Both NVIDIA and ATI have had video-transcoding features that until exploited by software are close to rudimentary.

Cyberlink, have been working on technologies that enable their software to harness the video-transcoding abilities of GPU's. Shuichi Takagi, CyberLink's vice president of of business development ran a demonstration of PowerDirector 7 that is capable of GPU-accelerated video-transcoding, on a recently launched ATI Radeon HD4850 512 MB, proving that the hardware and software is capable of converting four HD MPEG-2 movies into MPEG-4 simultaneously, in real time. According to Shuichi, it will take about 30 minutes to process four full-length movies and compress them into handheld-friendly 200+ MB files.Source: TG Daily

HOT DAMN!
I mean, I'm sure the GTX cards can do similar. But still.

Did they do one?

We should be happy that the GPU has come this far. It's not ATI or NVIDIA but we who win.

All you is need Cyberlink PowerDirector7. Good luck.

There's reason to ever need to do this with a single midrange card...... but nice :cool:


That's some impressive computing power.

Getting Cyberlink Power director 7 on Tuesday coming. Im super excited, this is fantastic news. Im well aware that the power of modern gpu's are yet to be harnessed, but WOW!

Anyone know which build of powerdirector 7 you need for this? I have build 7.00.1628 and it doesnt have this feature.

Dont think the feature has been released yet.

I just installed the trial of Powerdirector 7 to try to test this. It doesn't work for uncompressed AVI to divx or MPEG4 it used my CPU instead of 4850 GPU. Next I tried a MPEG2 transport stream and encoded it to MPEG-4 AVC and it still used the CPU, GPU load remained at 0%.

So not sure what conditions need to be met to allow GPU acceleration there was no options to enable hardware acceleration. Anyone been able to get it to work ?

It's coming from a vice-president of Cyberlink. It has to be true. If you want to verify it, you need:

The PowerDirector7 software
A BD/HDDVD drive (or any source of a lossless HD 1080p video) total of 4 sources

Transcode them to H.264 simultaneously.

will this work on hd3870?
Yes. But I really don't know when Cyberlink is releasing this feature.

so this can only transcode from bdrom, not the video files on HDD ?

Any lossless HD video source. I think content protection applies though, I'm not sure.

It hasnt been released yet. Its not available in the latest Powerdirector 7 build. The demo must have been using a prerelease version of the software.

What good is it if it works only on loseless bd and hddvd?! Anyway, I don`t care so much, cause my C2D handles perfectly any Full HD content, ripped or loseless. :)

explains more on the argument , why ATi always had better picture quality also ........... ATi gpus are really HD when it come to being HD.

just in from DAAMIT,
Hi,

PowerDirector 7 will have a refresh in Q3 2008 to enable AMD's Acceleratede Video Transcoding (AVT). I’ve been told by the team here in Markham that Cyberlink is about to put out a press release on this.

We offload any stage that can be parallelized to the GPU. We encode to MPEG-2 HD/SD (Blu-ray/DVD authoring, etc.) and H.264 HD/SD/Lower res (Blu-ray/File/Portable device).

On the source format, it depends on the application; I would recommend that you contact Cyberlink for this information.

Cheers
