REAL Core 2 Duo support in VS10 Plus, when?

fredb · Post by **fredb** » Mon Sep 04, 2006 1:53 pm

VS10 claims optimized mpeg encoding with Dual Core processors, which is untrue or buggy on a Core 2 Duo CPU (CPU usage while encoding never reaches 50% with a Core 2 Duo 6400).

Ulead fixed this in DVDMF5 Plus and now also with the DVDMF5 Sp1. Is VS10 next? I hope it is and Ulead is not thinking about trying to sell us a VS11 to incorporate optimizations that should have been present in the base product.

Htchien, do you know anything about this?

What you can do is go here http://www.ulead.com.tw/ulead/member/me ... e=TS&FS=us , sign in and complete a form reporting that VS10 + apparently does not support Dual Core processing. If no one complains to them directly, then it goes un-noticed. Don't rely on this forum as reporting issues like this, and expect any of the developers are reading it. H.T. is one of very few that do, and should be highley commended for that. I have posted before that it should be a requirement for at least 1 of the developers/programmers of each product, to read this forum daily.

Ron,

Thanks, but I had already done that and figured I would post the problem here as well to try and get Ulead's attention some other way since e-mailing tech support has never worked for me in the past (they never replied to any request on MSPRO, VideoStudio or any other software I bought from them).
I did get a nice surprise when I first bought VS9 or 10, I can't recall which one. I actually called tech support and a nice person in the US spent about 15 minutes on the phone with me. However this was not an advanced technical question, more on a usability issue. Nevertheless I was impressed once by Ulead's responsiveness.

You may also see different CPU usage patterns based on your encoding parameters.

I mostly use MSP8 now, and yesterday I was encoding a video several times using different settings. Using 2-pass VBR, I never got more than 25% CPU utilization, but using CBR, I got 50%. That's with a P4D 840EE, which appears as four processors (2 cores with HT support).

I think UVS 11 will not be out so soon so you do not have to worry about it.

I think it will be addressed in the upcoming service pack.

H.T.,

Thanks for your prompt reply.

I am glad to read that a service pack is coming for VS10 taht will incorporate the needed optimizations. Do you have any timeframe? Will we have to wait months or is it a matter of weeks?

I have an AMD X2 4600 dual core processor and neither DVD MF5plus or VS10plus utilise the second core on transcoding. Is this correct?

The trial version of DVDMF5Plus seems to work well and take advantage of my Intel Duo Core 2 E6400. As I wrote earlier, VS10 does not (yet).

I believe that the mpeg engine mpeg.now is based on Mainconcept's mpeg engine, which is optimized for dualies in its latest versions. I am sure that the interfacing with this engine is also a cause for good/poor encoding performance, a job Ulead has to perform.

For the upcoming service pack, I cannot say when because I'm not the sales person, but I believe it would be soon (not months I think).

For AMD X2 series CPU, I will see what I can do.

Hope this helps.

I got an answer from tech support:

The described scenario is not normal. There should be no problems using the VideoStudio 10 over a Dual Core system based computer whih is met the software's system requirements. Based on experience, these types of problems can be solved by uninstalling and then reinstalling your software. Please make sure to logon as Administrator before installing your software in WinXP to avoid restrictions. And it is also recommended that you restart your computer after every installation. You can also try installing the software on another computer and if it works normally then this proves that there is nothing wrong with your software. The problem may be caused by computer is already unstable or some other programs are causing conflicts and restrictions within your system.

I have access to a few other computers, unfortunately none of them a Core 2 Duo so I cannot test my copy of VS10 on another PC.
I wonder if anyone with a dual core can tell us if they see a cpu usage above 50% which would prove the use of the second core. All I've seen so fqar in the forums is people for whom this did not work properly.

I have already reinstalled XP Pro twice, and in one case just after the fresh XP install all I had was VS10. Still same problem.

Could it be that this person is not aware that R&D is already working on the problem in the Service Pack?

Not exactly answering your question, but:

On my Pentium 540J (i.e. 3.2GHz, HT, single core) and patched VS9, when rendering to DVD MPEG-2 i always get 70-80 % of CPU usage. That would mean that support for HT is actually working.

I just installed Windows Vista RC1 (32 bit). VS10 acts exactly the same way as under XP, no Duo Core 2 support apparently when encoding to mpeg.

Hi there H.T.
I notice that SP1 for VS10-plus is now available and I've downloaded and installed the update. With the update I now get approximately 75% CPU utilisation when rendering in MPEG, using an AMD Athlon X2 (dual core) processor. This is more than before but not the full 100 % I would expect from a fully multi-thread application.
So question is - do you have any update for us on what the optimisation of the MPEG encoder for AMD dual-core CPUs is
Thanks

My X2 3800 doesn't either in VS10+. I was quite dissapointed.

After I read that last post about SP1, I just installed it and my CPU during rendering is now at 80% - 90%

Thank you, ULEAD!

If you are not getting 100% utilization, you could have an I/O bottleneck -- are you reading and writing to/from the same drive?
