4x BADABOOM not so good ;p 20fps estimate time >>120min closing 3 BADABOOM's and fps goes up again.
All 4 same source DVD.

So you mean 4x 20fps each = 80fps total? What about 2 processes? If that's the case, then the quad core still wins...

I have't tried to compare xvid & BADABOOM,.

But by now its clear Nvidia's claim of 20x faster is Unreal! ;p
In 1 of the youtube clips below its already gone down to 4x faster,. ;p
But,.. when using BADABOOM you have a non active cpu to do other stuff. ;)
Here is some tech and tests,. BADABOOM VS Itunes

...on the other hand, if you get one of the upcoming octo-core CPUs, or even today's quad-cores, you should have enough cores to run some encodes on each of them. I typically run three encodes, one on each core so I have one core idle.
The GPU means that you could run even more in parallel, but I think there's enough cores on today's CPUs for most people.

But again, thanks for the review V1 :P - bit of a shame that you can't parallelise this much with Badaboom - would've expected it to at least be able to split itself across the two GPUs you have, for two concurrent processes, since it doesn't support SLI.

If you start BADABOOM it tells you that Sli is't suported but in the youtube the guy bracks about using 4 gpu's! in Sli mode,. ;p (dual GPU on 1 Graphics card is Sli?)

Still if a GPU concists of 240 core's then why should a quad core be faster,. Blur

(also i don't understand my quad core already says it is octo,.>?)

EDIT: BADABALONIE!! Itchingsmile

That's interesting. As for the GTX295, that's two GTX280s with an internal SLI (still is SLI).

I recall saying in another thread that more cores ≠ better in certain circumstances. I would've expected the encoder not to use all 240 cores though...

You've got HT enabled.

I'm pretty sure it's 2 GTX260s rather than GTX280s.

Maybe only using 1/2 power? Don't know.

1280x720 vid, 1.5 minutes in length. I'll have the output tomorrow. EDIT: I do this mainly for testing and for fun. I don't normally encode that slow, or with snow (codec) at all for that matter.

Do I win?

And no, my CPU isn't weak as piss. It's about the same power as zinga's Q6600 (which managed to pull 220fps on his PSP stuff here. Although I do get disadvantaged a lot here, because it's single thread.

Try it yourself? (My speed was for a 1280x720 vid).

Code:

:: Snow /w best settings

mencoder "YourFile.avs" -ovc lavc -nosound -o NUL: -passlogfile "something.stats" -lavcopts vcodec=snow:vstrict=-2:vpass=1:vbitrate=xxxx:pred=0:cmp=2:subcmp=2:mbcmp=1:qpel

mencoder "YourFile.avs" -ovc lavc -nosound -passlogfile "something.stats" -lavcopts vcodec=snow:vstrict=-2:vpass=2:vbitrate=xxxx:pred=0:cmp=12:subcmp=12:mbcmp=1:qpel:vme=8:refs=8 -o "output.avi" -of avi -ffourcc SNOW

FFMpeg should be able to do it too, if you like that over mencoder.

Badaboom works fine in win7 if you set compatibility mode to windows vista!

Have't tested xvid4psp VS Badaboom yet,. :(

Vegetano1 · 17/03/2009 01:27 AM

So i mailed Badaboom(Elemental Technologies) and got some feedback!
i just post some feedback i got since badaboom suport did't post here,. ;p (i had added the thread link in the mail)

If i disable Sli suport on my gtx295 i be able to use the multiple GPU option,. meaning i can run 2 transcodes

Quote:SLI will need to be disabled for you to be able select from the two GPUs listed in the dropdown menu in the Badaboom Advanced menu (you will also either need a monitor for each GPU or a switch).

Comparing trancodes and efficient use of resources

Quote:The point about comparing transcode speeds to iTunes is a valid one--it is mainly to catch the user's attention about the product. However, with high end cards, there will still be a significant performance edge over any GPU transcoder. To go along with this is how easy Badaboom is to use and the efficient use of system resources (offloading the CPU so that you can still use your computer for other tasks).

HD video transcoding piece of cake for badaboom!!

Quote:Elemental's technology really shows the greatest performance advantage converting at the higher resolutions because it involves the most processing and is easy to keep all the cores busy. Wee are still optimizing for having the best advantage across the board, but with the way video is progressing, having the best performance converting high resolutions is a good place to be.

notebooks run slower on both GPU & CPU's ;p

Quote:One of the videos in one of the posts in the thread features Badaboom being demoed on an NVIDIA mobile GPU (on the notebook). This GPU is one that is very small and fanless, so the performance here will not be as great as compared to a massive CPU. However, compared to the CPU on this board, this GPU does very well with Badaboom.

Elemental Technologies Thanks for visiting Endless Paradigm! :) Looking forward to any updates of BADABOOM!!

Yeah, it will work better with higher resolution encoding, though for most people, they'll only ever convert for their portable device (unless people want to transcode downloaded videos for Blu-ray but methinks that most Blu-ray players in the future will support "DivX" playback so this may be more moot).
I can't say offloading work from the CPU is a big point, unless you don't have many cores and/or you're trying to do a fair number of simultaneous encodes. Considering current quad-core CPUs, it's unlikely you'll use all 4 cores for normal tasks. Allocating 2 cores for a CPU encoder still does give you 2 more cores to do ordinary stuff.
Of course, a possible advantage of the GPU encoder is mass parallel encoding, but as you've shown, it doesn't appear to really be any better.

Thanks for the info and email Vegetano1, and ES for the reply. Badaboom is still rather new and a work in progress, so can't really be directly compared to a mature encoder like x264. I'm still a little doubtful for the performance gains. I mean, a GTX295 is like a AU$850+ card, whereas my Q6600 CPU is like AU$285 (Phenom II X4 940BE is probably better value) and there doesn't seem to be a huge difference in performance. It may be improved, though I'm dubious as to how much improvement there can be. Anyway, it's something to watch I guess.
