Selectively Pre Render crashes!
 

I'm cutting some HDV24p footage for a draft edit at the moment and for the first 20 mins all transitional work which includes effects was successfully selectively prerendered. Now every time I select even the smallest piece of the timeline for rendering I get a crash with the following 'An error occurred during the current operation' 'an exception occurred'.

When I select Selectively Prerender I chose the following;

Prerender as; Video for windows AVI
Default template, uncompressed.
Render loop region only

I'm running Vegas 7.0d
Pentium Dual 2.67 e6700
2 gig Ram
700 g video storage

I need to sort this out before the client comes in for the edit otherwise I'll look like a muppet! Any ideas would be very welcome. Am I asking the machine to do too much?

ok, now Vegas goes through the motions of rendering selected region, but then just closes with no error message and neither do you get the chance to recover the file through auto save!

the avi itself is causing the crash, obviously.
How are you displaying it? It likely is that the uncompressed media is overburdening the system when it's being downconverted to DV to be externally previewed, if that's what you're doing. Otherwise, it would appear that your system simply can't manage the uncompressed throughput.
Why did you render uncompressed?

Could you please explain why you are so certain that the AVI is the fault here? I'm a cameraman, not an editor so would love to understand this better. Do you mean this is a fault with the Cineform part?

I'm not previewing on an external monitor and I'm curious as to why you ask why I render uncompressed? I'm using Cineform to convert to AVI so isn't the footage already compressed for my workflow? What would your recommendation be?

There were only 2 faster processors available when I had this machine built over Christmas. Surely 2 x 2.66 processors and 2g ram and cineflow are powerful enough to handle this???? My video storage drives are RAID 0 and both sata7200 so there shouldn't be any probs there! It was working perfectly for a while before?! so whats happened?

I'll really appreciate your thoughts on this and suggestions for editing 24p hdv without error in the future.

thanks

You're not editing HDV. You're editing uncompressed HD. This is why I asked why you rendered to uncompressed, which you indicated in your first post.
Right Click the media in the Explorer, go to Properties, and tell us what format the file is. If it's truly uncompressed as you indicated, then I'm positive it's the file causing the crash. Very few systems are capable of managing a 444 file on the timeline, which is what uncompressed is. Your hard drives can't output it fast enough, your system can't swap it fast enough.
If it's _not_ uncompressed and is Cineform, which you allude to in your latest post, then there is something else going on.

Sorry if I confused the issue!

I'm editing HD shot on a JVCHD200e at 24p 1/48 and captured using Cineform Connect HD. I then open the Cineform AVI from Vegas into my project media. It's definitely not 4:4:4!!

I always selected 'default uncompressed' when selectively pre-rendering as I assumed (probably incorrectly) that Vegas would compress the clip selected, thus the material being compressed twice, once by Cineform, then by Vegas. I assumed that 'default' also referred to the default settings of the project, which are;

HDV 720-24p (1280x720x23,976fps)

So Douglas, have I been selecting the wrong pre-render settings? Is this the reason Vegas has been crashing when I pre-render? I'd welcome your advice on how to successfully selectively pre-render with this project setting.

Thanks

p.s Go easy on me....I'm a cameraman!

ok, think I've solved this but it now looks bad!
 

I sat down and read the manual and as the project is 24p and the 'Allow Pulldown removal when opening 24p DV' tab was checked in my project prefs. I have to select;

NTSC DV 24p (inserting 2-3-3-2 pulldown)

from the options in under 'selectively pre-render', even though I'm PAL.

Well, this has worked (as did 'HDV 720-24p intermediate' for some time until a few recent crashes that prompted this result) but the size of my preview output for the pre-rendered footage has been stretched horizontally and thus letterboxed. This looks terrible! When you watch the project in the preview monitor the pre-rendered footage looks crap! Can this really be right?

I'd really really appreciate some help on this and an explanation as to why (so I can learn)! Was it a mistake to keep that 'pulldown removal' tab checked?

Thanks for all your help so far on this great forum!

Help....please......anyone?

Selective Pre Render settings
 

Can no-one help me here? please!

Stuart, I'm getting the same error as well. This is a 25 minute project with all kinds of different videos included as well as 3 nested projects. Were you able to find a fix? I wonder if the latest Sony update would help?

Just as a passerby, I was wodering what the result of this check was?

George I've had no luck on this issue and no help in the way of replies.

I just build a RAM preview now, which although not the solution I was hoping for, it gives a proper picture in preview and doesn't crash my machine.

I'm sure this isn't right, but until I find a roper way around this RAM preview will just have to stay!

ok, maybe I'm after an answer that deosn't exist? Who knows! Is there anyone out there that selectively pre prenders without issue??

I sat through an entire 2 day edit with a client moaning about the fact that he couldn't watch the real time effects on the timeline as they'd look.

I kept having to build RAM previews. Very frustrating!

I'd really really, no REALLY, love to hear how those of you pre render in 24 or 25p! Does your preview image resize in the preview monitor/window, does Vegas crash? what are you doing exactly? I follow Vegas manual instructions and the frame size seems to change aspect ratio or something. It's horrible!

Please guys...I need some help on this one. It's doing my head in!

Stuart, I have been rendering HDV every which way in Vegas for a week now. First, tell me, after capture, what are you rendering for? DVD, web delivery, view on own computer? Are you trying to convert to SD for DVD? Or just render an HDV file? Check your project properties BEFORE rendering and write them all down. Then when you choose RENDER AS, and AVI, write down every box you have selected, and deselected and every setting chosen, post it here and let me look at it. I will take a shot at diagnosiing your issue. I have had success in EVERY format. THanks. J

You are using Connect HD or Cineform to capture and converting automatically to intermediate AVI files to timeline? CFHDcap.avi?
