Keeps crashing when I render … PLEASE HELP, has to b finished by end of day

[Mike Kujbida]

Try rendering to AVI first and then convert that to WMV.
It’ll be a lot less strain on your system.

If it still crashes, break it up into sections and then piece it back together for the final render.

Hi,
I could do that, but I was just thinking I should be rendering to Mpeg2 to import into DVDArchitect, should I ?
As soon as I try to render it says ‘An error has occured during the current operation’.

[Mike Kujbida]

If your end product is a DVD, then yes, render to MPEG-2.
Because it’s so short, use a CBR of 8,000,000.
You’ll have to scale it down though as you won’t be able to do HD, only SD resolution.

Your repeated errors have me concerned though.
I’m wondering if you have a corrupt clip in the timeline somewhere.
What kind of material do you have on it?

[Lauraitt]

Yeah the end product will be a dvd.
I had files imported from a server, I have now got them imported locally.

I am rendering right now as an avi, its at 65% after 1hr20mins which is ok but I need MPEG-2, at highest quality as this dvd is going to distributors worldwide.

On my timeline I have hundreds of different video clips, photos, WAV files for the voiceover. I know that it is massive in size but I dont see that as a reason for it to repeatedly crash.

How would I find out if there is a corrupt clip in the timeline?

Thank you for your help
Much appreciated,
Laura

The only way I know of finding a corrupt clip is trial and error replacement 🙁

As far as quality, if you chose “Best” as an AVI render option, that’s as good as it’s going to get (without different render options that would increase render time drastically).

For an MPEG-2 render, a CBR of 8,000,000 is as good as you can do it.

Sure hope this works out for you!!
Keep us informed of your progress.

Laura –

I’m sure this is not much help but it does sound like you have some kind of corruption problem with something on your timeline. However, if you can finally get an avi render, then bring that back into Vegas and you should be good to go for the mpg2 or wmv renders. Let us know if it works out.

First, I’d not recommend using avi as an intermediate. Particularly DV avi. You’re tossing a significant amount of quality out the window.
Second, look to your setup.
Reduce render threads to 1.
Set Dynamic RAM to a low value, I’d recommend 128 or 256.
Clear ALL background programs so nothing is running but Vegas. No antivirus, no mail, no Corel, no other background app.
Be sure heat isn’t getting you. This is a common problem when rendering to CPU-intensive formats.
Render to MPEG2 for DVD, WMV for web. I’m confused as to how/why WMV has entered the discussion?
CBR at 8Mbps will provide a very good image (not the best you can do, but you should be worrying about getting an output first).
Are any of your stills larger than 2K in any dimension? Are they tifs? JPEGS? PNGS? TGA? PNG and TGA work best in Vegas, and no image should be larger than 2K in horizontal or vertical pixel value.

[DSE/Spot] “CBR at 8Mbps will provide a very good image (not the best you can do…).”

Spot, what are your recommendations for short videos like this?
I’ve been told (wrongly??) that CBR is the way to go for best quality.
Should I be using VBR instead?
If it’s less than an hour, my bitrate calculator says 8,000,000/8,000,000/4,800,000.
WOuld this give a noticeably better result?

[Douglas Spotted eagle]

It’s content-dependent. If there are static and then high motion scenes, I wouldn’t use CBR. If it’s fairly static, then CBR is the best option. My bigger point is that she can go to a higher bitrate (I didn’t read the length) which often translates to better quality but not always. Again, it’s content dependent.
There are many other ways to get better video output from an encode as well that have nothing to do with bitrate, but rather saturation, cropping, etc.

[Mike Kujbida]

Thanks Spot.
The content part I understand.
However, I’ve always burned DVDs with the understanding that the max. bitrate should be limited to 8,000,000.
This may have even been mentioned in an earlier Vegas/DVDA manual.
You’re saying that going even higher (like 9,000,000), allowing room for audio, is OK with Sony software and good media?
