ATI X1000 and HD to MPEG-4 encoding

http://www.extremetech.com/article2/...1880669,00.asp

Avivo Transcode

Quote:
So how fast is it? We shouldn't get into serious benchmarks while the application is in such an early state, but just to give you a taste of the numbers, we ran a few tests. Our test machine was an Athlon 64 X2 4800+ with 1 GB of very low latency RAM and a Radeon X1800 XT graphics card. We encoded a test clip from the movie The Rock,—a4-minute and 50-second clip that tends to be very tough on encoders. It's the same one we use in our CPU benchmarks.


Encoding this nearly 5-minute clip, at DVD resolution, takes about 2 minutes 17 seconds with DivX 6, with single-pass encoding at 1 megabit. Windows Media Encoder can produce a high-quality single-pass transcode to WMV9 at 1 megabit in about 4:35. Windows Movie Maker 2 takes a few quality shortcuts to produce a DVD resolution clip at 1.5 megabits in 2:05. That's all pretty good: This is, after all, one of the fastest CPUs money can buy, paired with very fast RAM.

How fast does ATI's new Avivo Transcode app get it done? Try 24 seconds! Okay, that's "give or take a second," because the MPEG-4 profile finished a 1-megabit encode in 23 seconds, the MPEG-2 and Windows Media Video 9 profiles were done in 24, and the DVD profile at 6 megabits finished in 25 seconds. That's all at the default full resolution, too. Crunching down the output resolution by choosing the "WMV9 for PMC (Portable Media Center)" profile at 700 kilobits per second completed the job in 17 seconds.
I thought this had more to do with HDTV and storage media for HDTV-quality than gaming hardware.

Re: ATI X1000 and HD to MPEG-4 encoding

The mpeg4/HDTV hardware capabilities of these new cards still need to be proved...

Hm. The article is not a theory but reports test results.

Re: ATI X1000 and HD to MPEG-4 encoding

That's true, but 'Ive still not seen many tests or reviews about them at all.

Did you?

Re: ATI X1000 and HD to MPEG-4 encoding

Not many, because it's quite new. You probably wanted to mean you want to see more proofs. If ATI can do it, Nvidia can't be too far behind.

Re: ATI X1000 and HD to MPEG-4 encoding

Yep, exactly. Currently ATI is ahead with it's new range of X1x00 cards.

Re: ATI X1000 and HD to MPEG-4 encoding

X1800 seems too expensive, but X1300 costs much lower. (US$500 vs. US$120.)

I'm waiting for the X1600, should be released soon here in europe (hope, hope, hope).

Re: ATI X1000 and HD to MPEG-4 encoding

The Pro/XT/XL model of course, that's what I meant.

Re: ATI X1000 and HD to MPEG-4 encoding

ha awesome now I know where all those ancient passive first generation pentium heatsinks have gone to! But on a side note, is this app actually doing the encoding through the cards "specially created HDTV chip" or is it just using the GPU?

Re: ATI X1000 and HD to MPEG-4 encoding

Maybe both, I don't know for sure. Do you mean Pentium 60 and 66MHz or Pentium 75MHz? Pentium 75, 100, and 120MHz had cooling fans. I don't think any 486 processors had fans. Can't remember about Pentium Pro and Pentium 60/66.
