Are there issues with quad cores and 8.0c?

I am wanting to upgrade to a Core 2 Duo Quad from my dual and know that a lot of people here use 8.0c with a quad. Every now and then I seem to come across a post that talks about the issues with 8.0c and quads?

Are there issues or is this just for users with certains setups much in the same way there are always some people that have various issues that the majority of users do not have?

None here, so far.

Nope, my quad-core and Vegas 8.0c get along just fine.

I DO have problems with my Q6700 quad.

On "large" AVCHD projects, I can ONLY render properly after I shut down my quad in the BIOS of my PC.

Small and medium projects render fine. I never have any instability when building projects, Vegas 8c is always rock solid. Problems only happening durring rendering the big HD stuff.

Search around for threads on "rendering problems". You will find many complaints about quad rendering.

I LOVE Vegas but that one flaw drives me bonkers!

Cliff, why do you think you are having problems and others aren't?

Hulk wrote on 3/8/2009, 7:45 PM
Cliff,

Thanks for responding. Could you quantify "small, medium, and large" projects just so I know what scale you are talking about?

How long? How many clips?

No problems with my Q6700.

Cliff... at least 80% of the people doing avchd are having problems. I NEVER had crashes with HDV. I could do just about anything with it and it's solid as a rock.

AVCHD.... different ballgame.I have crashing issues... artifact issues... etc. But I don't attribute this to quad core problems. I think it's more the avc render engine that's bugged a little somehow. When I render a avchd time line over to mpeg2 I have no issues. Or when I convert to cineform avi... again, no issues. It's just when I try to work with avchd on the time line or try and render it over to avchd that I have the problems.

I have to admit that I've searched the web a few times for signs that Intel Quad setups might have memory problems. Never really found anything, but comments in this forum have often made me wonder if there was a hardware problem out there.

No one here has ever been able to pin a problem on a quad setup, but on the other hand very few of the people with quads have been willing to consider such a thing. That's probably psychological - the thing you spent the most money on is the thing you're least likely to consider might be broken. Still, there's not much evidence that there's a problem with quads.

Might be that the people willing to plow money into a quad for Vegas are also the people who push the envelope, so it looks on the forum like quad setups have problems when they don't.

I don't use AVCHD, so if there are problems with Quads and AVCHD, I wouldn't have experienced them. On the rare occasion that I've gotten some AVCHD footage, I've converted it to Cineform before I've done anything with it.

Hi,

Yes - there are issues with quad cores and 8.0c!!!

I have constant problems when rendering TO AVCHD (full HD) formats, but only IF I have all 4 cores in use (4 treads selected). Going down to 3, 2 or 1 threads, Vegas 8.0c works fine.

This IS a bug that is recognized by SCS and will hopefully be fixed in the near future... 8.1 is NOT plagued by this error, only 8.0c.

So the workaround is to use less threads than CPU cores, and you should be OK. The sad thing is that you are not fully utilizing your CPU potential, but as long this brings you to the goal (albeit a little bit slower) - I can live with it.

BINGO!

The post above is true.

That's what I was told by SCS too.

So it's a Vegas/AVCHD issue, not a computer issue, right?

TheHappyFriar wrote on 3/9/2009, 7:03 AM
must be, I don't have any issues with HDV/uncompressed HD content. But I've seen people complain that Intel Core Quad's can have issues all across the board. Most times there's a work around (issues aren't everywhere, just in some specific programs it seems).
Christian de Godzinsky wrote on 3/9/2009, 8:00 AM
Hi,

It is surely a Vegas 8.0c issue, all my other applications that runs of all 4 cores works like a charm. Again, 8.1 works also flawlessly on 4 cores, rendering the same project... The ONLY reason why I don't use 8.1 all the time - it's well known (lack of plugin support).... But that's another story...

I don't think Vegas is alone in having these issues. Other NLEs seem to avoid / minimise the risk though the use of proxies or intermmediate codecs. I also doubt it's quad cores that are the problem as such, it's just more cores = more threads = more resources = more RAM needed.
A common rule of thumb with other systems is 2GB / core, more is better. As noted with Windoz that means a 64bit OS. Vegas is not alone in having limited plugs that work in 64bit either.

"I don't think Vegas is alone in having these issues."

Yup. Just about any OS that handles (or tries to handle) avchd on a native level has problems.

Some of the cheaper programs have fairly reliable smart render systems so if your work qualifies for smart render then you're in luck. But REAL rendering..... it's a mess out there. You're best to go intermediate.
cliff_622 wrote on 3/9/2009, 10:42 AM
For me,...these "problem projects" of mine have several HDV and mixed AVCHD tracks. They also have .jpgs too.

Again, these projects assemble and preview 100% fine!

They only crash on rendering with Quad processors "on" inside the PC BIOS. The EXACT same .veg project will render fine with quad shut off in BIOS.

I CAN render simple AVCHD and HDV fine with Quad on. (one or two tracks)

No other HD media I have displays this problem with Quad.

I hope the Vegas guys fix this in V8D before V9 next month.

I, too, have rendering problems (usually to Cineform intermediate) that sometimes can be fixed by disabling multicore rendering in Vegas or by rendering on my old P4 on an Intel MB. However, on my longer (2-hour) and more complex projects, even that rendering work-around fails and I have to put markers at 2-min. intervals and render between all the markers with Peachtree's Veggie Toolkit batch rendering skript . . . so I, too, think it's a memory problem, not so much an issue with quad core.

My Q6600 works flawlessly when building a Vegas project, and with every one of the approximately 100 other programs on my computer. I'm also able to render short or simple projects (no feathered masks, for example) with all 4 cores pumping out lots of bytes.

Having said that, a few weeks ago I was seriously considering swapping out my Q6600 for an E8400, which can OC gracefully, with only air cooling, to 4gHz, or beyond. Sure is something I think about while waiting for a render that is poking along with one core. But then I read that Vegas 9 might be out soon and (let us hope) may fix this problem which is my ONLY complaint against Vegas. My conclusion: get a Q6600, O.C. to about 3gHz, and pray for a quick fix from Madison.

I just upgraded to Vegas Pro 8 from MS Plat Pro 9 and I haven't yet experimented with rendering as I'm learning the new features of the software. I have a 2.4 gig Intel Quad Core, and I rendered several projects out under MS 9 that worked fine with the Quad from AVCHD files. I did do some experiments though, and found that projects where I converted the AVCHD to .m2t format only consumed half of the processing power that working with the original files did. That's a big difference and I can imagine working with a large project could really stress the processor and conceivably cause crashes.

If I had the money right now I'd buy a Intel i7 3.0 gig quad core processor. They supposedly work wonderfully with video editing software.

I have only seen minor AVCHD probs. on my Quadcore, but I think it is like Blink says, not really a processor problem, but more AVCHD.

I have made big 2 cam projects in DV with hours of editing, with absolut no problems at all on my quadcore.

NAB 2009 convention in Vegas.

The next version of Vegas will be there. I dont know it if will carry the "Vegas" name though. I have heard "rumors" that it might have a new name. (I'm very unsure of that)

I DO know that you can edit HDCAM video with the new version and doesn't need any special hardware. (I'm very sure of this)

Vegas has been capable of editing HDCAM since V4.

Define "special hardware", to playout 1920x1080 4:2:2 uncompressed you're going to need some pretty fast disks.
