HiYa all

Well I have a strange one.

RE Vegas Pro80c
Using XP pro SP2 (32bit)

I am trying to render out 1hour of PAL mt2 video to PAL AVI widescreen and at exactly 4minutes & 42seconds my system crashes.

I have tried a different piece of (1 hour) mt2 footage and the same thing happens.

Also tried to render it to another format (template) HDV 1080-60i intermediate and the same thing happens.

I have tried rendering out now about 7 times with the same result.

Has anybody got any clues to why this is happening.

L

PS I am thinking of changing to Vista. What is the best version for video editing (only) Home, Business or Ultimate?

Comments

i'm no expert, but you don't say what your set-up is? how many hd's, where are they, etc.,

i can understand a render crashing out at a certain point (been there, done that), but to have different clips crashing at exactly the same time is strange to say the least.

i think we need more details....

See if this helps.
From the Vegas FAQ on Edward Troxel's (jetdv) site:

By default Vegas renders OpenDML AVI files, also known as ODML or AVI 2. This allows AVI's to overcome their historical 2 GB file size limitation while retaining partial compatibility with older readers that don't fully understand the new format. In the sake of ultimate backwards (partial) compatibility, the format limits the amount of a data older readers can access to the first 1 GB of an OpenDML AVI.

In most cases, Window Media Player should be able to see the entire duration of a large OpenDML AVI file rendered by Vegas. However, in Options => Preferences... => General, make sure that "Strictly conform to AVI2 specification" is not checked (unchecked is the default). If it is checked, Windows Media Player will most certainly only see the first 1 GB of the file, which for DV comes out to about 4 1/2 minutes.

As of version 5.0.2, QuickTime for Windows still doesn't completely handle large OpenDML AVI files, so it will only see the first 1 GB (4 1/2 minutes of DV). RealPlayer is also limited in this way. In fact, most readers not based on Microsoft's DirectShow will probably show this behaviour, and those that are based on DirectShow will show it as well if "Strictly conform to AVI2 specification" is checked in Vegas.

If OpenDML .avi is unchecked, Vegas will write standard AVI's that should be fully compatible with all AVI readers. However, they would then be limited to 2 GB in size.

Are you working on an external hard drive? Did you reformat it as NTSF (they always come preformatted as FAT32)? FAT32 formatted hard drives have a 4GB size limit and will not allow you to write a video file larger than that.

As far as which Vista to use, I use Vista 64 Ultimate. This is the way to go since Vegas 8.1 is now available in 64bits.

Could be coincidence, but DV video is 13,644,000,000 bytes per hour; 13,324 kBytes per hour and 12.7 GBytes per hour (the 1,024 thing is why they're not the same).

4 minutes and 42 seconds is 282 seconds. An hour is 3600 seconds.

( 282 / 3600 ) * 12.7 GBytes = 1 GByte, almost exactly.

What type of storage are you rendering to, and how is it formatted?

Nice math work by the way...

Hey thanks for your interest

OK

I am rendering to internal Raid 0 2x160 drives with approx 80GB free, both NTFS.

More details are that it crashes the whole computer, then the computer does a reboot.

I have just done a Windows Memory Diagnostic test with no errors, so Ram and Mobo seem ok.

Just a strange thing that both clips stop at 4.42....mmmm the twilight zone.....

I have done many renders in DV without any probs but HD has been given me headaches.

How impressed are we with those number John, wow.

Hope the above info helps.

Did you try to render just the problem area - 4:30 to 5:00 - time?
Do you have many large stills?

a quick test might be to render it to an external usb or firewire or esata drive and see if that solves it.

Not sure WHICH avi type you're rendering over to but if you go into the template CUSTOMIZE features you will see a check box at the bottom marked: "Create open DML (avi version 2) compatible file".

This checkbox is for creating large avi files to fat32 disks. CLEAR that check box and see if that helps.
