Mpeg2 720p plays fine on my render workstation but not on the another ??

plainman007 · 06-24-2009, 04:07 PM

I had rendered my latest project from my NLE to an mpeg2 1280x720, 30mbps file for a presentation. The rendered file runs fine and smooth on my main workstation. But the file stutters and runs in slow mo with audio dragged out on the presentation system. Both systems are dual core and with 4 gb ram each. Seperate media HDDs etc. Task manager reports CPU usage is just 10 to 20% when its struggling trying to play the file. So i dont think its a system bottleneck.

Is there a recommended and reliable codec pack that allows us to play the above mentioned file please ?

Thanks

Bump

.
Anyone ??? Please ?

Not sure; I haven't worked in hi def yet. I can envision, though, that different codecs would run faster/slower & more smoothly/less smoothly than others for this purpose.

I think the best thing would be to post this question at the Sony Vegas forum. There should be lots of people there with relevant experience.

Hi Ctal,

I think ill just have to try codecs. But one slightly offpath question. Do nivia cards etc handle hardware decoding of mpeg2 hd ? Ive read that there are mpeg2 HD pci cards, purely dedicated to hardware mpeg2 decoding.

Ive also heard Nvidia tout their cards as 'PureVideo' HD decoding and that they boost hd mpeg 2 performance by hardware decoding thereby keeping CPU usage to a minimum.

Any truth in this ?

Thanks my friend...

**ctal** · 06-25-2009, 04:32 PM

True!

PureVideo HD

Here are some cards with that feature:

PureVideo HD - Buy Graphics Cards, Software, Drives to Build Your Own HD PC

There are probably zillions more available, from these and other manufacturers. Check out the cards (and the user reviews) at NewEgg, searching on the series you see listed for the cards above (8800GTX, 8800GT, 8600GTS, 8500GT, 8400GS).

Hi Ctal,

In fact the first link was what i was just reading last night after i posted the last reply. But what i couldnt find a perfect answer to in those Nvidia pages was even if i have a clean install of XP with no other codec package installed will it handle Mpeg2 HD ?

Thanks

I don't believe HD standards or codecs were really developed or finalized at the time that Windows XP was released. Personally, I would not expect a fresh XP install to perfectly (or maybe not at all) play HD video.

**ctal** · 06-26-2009, 11:14 AM

I'd imagine that it would, because it is performing the decoding in the video card hardware, and control of that hardware would be performed by the Nvidia driver software (which obviously you would have to install). The os's hd capabilities and other codecs which may or may not be installed would seem to be irrelevant, based on Nvidia's description.

zsaz1029 · 06-26-2009, 11:25 AM

Given some more thought to it, I agree with ctal. The NVIDIA software that would be installed should take care of all the decoding that's needed.

**ctal** · 06-26-2009, 11:42 AM

Thanks for the kind words, Zsaz, although (understandably) they went away when you revised the substance of your post

I would liken it to the process of creating an mpeg2 file on a computer, using some codec, then authoring it and burning it onto a dvd, and then playing back that dvd in a dvd player. The codec on the computer is used to encode the mpeg2, but the decoding is performed by dvd player hardware. Likewise, in this case, some codec is used to encode the file, but video card hardware is used to decode it, with the driver software serving as an interface between Windows and that hardware. At least, that's how I would interpret Nvidia's description.

plainman007 · 06-27-2009, 04:00 AM

Hi Ctal >

Actually speaking, the system has nothing but windows xp and no other codec packs installed. Ofcourse ive installed the Nvidia drivers. What do you think i should do ?

**ctal** · 06-27-2009, 04:20 PM

Are you saying that the presentation system, which has the problem, presently has a PureVideoHD-capable video card?

If so, which one?

If not, you could consider getting one, or else follow my suggestion of asking the Sony Vegas forum users for codec recommendations.

plainman007 · 06-27-2009, 05:56 PM

Dear Ctal,

Yes the presentation system has a Nvidia Geforce 7300GS which was listed as PureVideo And HD capable. Plus it supposedly has Mpeg2 HD Hardware decoding.

What should i do Ctal ?

zsaz1029 · 06-27-2009, 07:15 PM

Actually plainman007, unless I'm reading wrong, that is NOT a Purevideo HD capable card. The website says they start with the Geforce 8 series and above.

Purevideo capable and HD capable does not equal 'Purevideo HD' capable.

**ctal** · 06-27-2009, 08:59 PM

I agree with Zsaz:
