Does anyone know when Vegas Pro 8.0c will be available for download ?

Thanks !

I don't know specifically, but I heard that it will probably be later this month (June) along with the release of DVD Architect v5.0. Of course, I could be wrong.

Hi,

Hmm... this is a long awaited update...

Is there any information (or any rumour about) which known issues (problems) it adresses?

To my understanding there is also possibly some improvement in the AVCHD editing speed?

That's what I hear.

Hi,

Thanks John for the "confirmation" ;)

It seems that the current 8.0b version is NOT using all available cores efficiently in preview, as it does most of the time during renders...

If SCS only would get this fixed, there would be a tremendeous difference in editing speed, at least for us with quad-cores :)

Hopefully some other essential fixes are included too..

How do you know that vegas doesn't use all four cores during rendering ?

Go to the bottom of the screen
>task bar
>right click
>task manager
>Processes
>vegas
>right click
>set affinity
>make sure all 4 cores are ticked.

Paul.

Paul,

Thanks for your comments. I wrote:

Exuse me if I did not state it correctly (my mother tongue is not English), what I meant was: "why does not Vegas use all cores during preview, when it uses all cores during render"...

Probably there is a fix in the works... hopefully already in 8.0c

How do you KNOW Vegas Preview isn't using all 4 cores?

mine only averages 50% on a quad core Q6600

OK? But that to me doesn't mean it isn't using all 4? Yeah? All it means is that there is 50% activity.

Now, you are comparing rendering to Preview. I could argue that rendering is a constant stream - mostly! - Previewing has to take into account a bit more than that. I am out of comfort zone on this, but there could very well be a difference ion the management of the CPUs when dealing with Previewing than render - yeah? Well, it would seem that there is.

If you have done the 4 affinity test then you/I/we have to believe that all 4 CPUs are being utilized. To what %-tile efficiency and for what task, your guess is as good as mine.

Hi,

On my quad core QX9650 (@3,8GHz) machine - all cores run nicely close to 100% utilization when rendering - and the process is really pushing the CPU to its limits. The only time this does not happen (during rendering) is if I have used some filters that are not multi-thread enabled...

During preview and working to the timeline, I NEVER experience such high CPU load, it is at most something like 20..35% - average on the 4 cores.

Definitively, the preview of the Vegas timeline is not optimized for quad cores. I have all my settings optimized (affinity, number of cores etc.).

The reason for the slow response is not my system. The memory bandwidth is 8.5Byte/s (4GB of DDR3), and my two internal and one external disk transfer better than 70MB/s. Theys scream and are able to handle those streams on the timeline with no penalty.

I live in the hope that 8.0c adresses this. Hopefully it is released the same date as DVDA5 (16th of July).
