Bit-Rate?

[Mike Kujbida]

[William Van] “I’m trying to burn a 40 minute DVD from a .MTS file but after about 25% of rendering my computer shuts down.”

Sounds like an overheating or an underpowered power supply issue to me.
When was the last time you took the cover off and blew out the dust bunnies?
Download and run Core Temp/ and see what it says.

“I can burn a 3 minute video but it takes up about a third of the disc.”

Do you mean physically or the file size?

“Someone said that my bit-rate was probably too high and I need to lower it to 6 Mps.”

For a 40 min. DVD, 8 Mbps is a good rate and one that I’ve been using for several years for anything that’s 70 min. or less.

“How do I lower the bit-rate in Vegas Pro 10 for burning a DVD?”

Click the Custom button next to the Template box, customize it, give it a name and save it as a preset.

“Click the Custom button next to the Template box, customize it, give it a name and save it as a preset”

I don’t see that in my Vegas.

I’m clicking > tools > burn disc > DVD

It lets me choose video format and burn speed only.

File – Render As brings up this dialog box in Pro 8 (not sure what version you’re using).

[William Van]

I see that but I am not using DVD Architect.

I am not rendering before I burn the DVD.

I am using Tools> Burn Disc > DVD with a .MTS file. It automatically renders it to MPEG-2 while it burns. But there is no way to set the bit-rate.

A 3 minute video takes up about a third of a DVD. That means I could probably get 12 minutes max on it.

I thought you could get two hours on a DVD.

“But there is no way to set the bit-rate.”

That’s correct. This method will not give you that option.

“A 3 minute video takes up about a third of a DVD. That means I could probably get 12 minutes max on it.”

I’ve gotten up to one hour (that seems to be the limit) on a DVD using this method.

“I thought you could get two hours on a DVD.”

I’ve burned a 2.5 hr. program to a single-layer DVD but you have to use the method I described to do it.

OK, when I render like this at 6Mps it is still shutting down my computer.

The core temp says I’m running at about 92 degrees c

Is that too hot?

How would I know if my power supply is not powerful enough?

Is 600 watts enough?

I have a quad core Phenom and a Nvidia GTS450.

[William Van] “The core temp says I’m running at about 92 degrees c
Is that too hot?”

Yes it is. My machine never goes over 60 C., even during a long render.

“How would I know if my power supply is not powerful enough?”

When things like this start happening on a regular basis.

“Is 600 watts enough?”

It depends on factors such as your CPU, number of hard drives, video card, etc. but my guess is no
I have an older QX6700 quad core with a 750 W. supply and a large cooling fan.
When was the last time you took the cover off and blew out the dust bunnies?
I had a severe overheating problem a few years ago and had to get the CPU cooler paste replaced as the original paste had broken down.

I built this computer about 9 months ago.

Phenom II X4 3.2 Ghz
1 harddrive
8 GB RAM
Nvidia GTS 450

How can I make it run cooler during rendering?

The case and processor are stock.
1 case fan, stock fan on top of processor.

Would more case fans help?
Bigger fan on processor?
Would a bigger power supply help lower temp?

Don’t have any problems with this computer except when rendering large video files.

Thanks

Sorry but I’m not a hardware guy so I don’t feel qualified to answer your questions.
One recommendation I will make is to add another hard drive.
Keep your OS and programs on your primary drive and all your video and other assets on the secondary drive.
