Smart proxy crashes when creating a file greater than 1GB

Hi,

Everytime I use a large AVI file and the smart proxy starts working my VS10 crashes at the end of the proxy file creation. This only happens if my smart proxy uses compression and the end file is greater than 1Gb or there abouts. I've tried various codecs but all cause the same problem.

I've installed the latest fix pack and the disk I'm using has plenty of free space, at least 400GB. The original files are NTSC DV type 1 AVI files, 720x480 16:9.

Any ideas? Is this a bug?

Thanks in advance,

Steve

I may be missing something here, but why are you using smart proxy with what appear to be standard DV videos? I thought smart proxy was only for use with HD video...

Ken is right, smart proxy is for High Defenition and a computer with a processor that is slower than a 3.0 Ghz. Thats probably why you the program is crashing.

Hi,

Thanks for your replies. The smart proxy allows you to ,and I believe the default is to, create proxy files for 720x480 avi files. If you turn the proxy on it will start to work with regular files. The documentation says that the smart proxy is there to... "speed up editing of HDV and other large video source files." My 720x480 avi files are around 13GB which I think counts as large video source files. And I've had no problem with VS accessing and using these files directly.

My processor is over 3GHz. Besides which a system should never crash if there are no bugs just because a processor is slow as the same code path should be being executed. (It could do due to race conditions but this would still be a bug none the less).

Has anyone else tried this?

Haskey,
If you have a 3GHz CPU, you are wasting your time with smart proxy. It is intended for users with old, slow computers that can't cut the mustard with high definition video. It will not improve picture quality.

BTW, video editors are extremely complicated and you will find plenty of bugs if you step outside established workflows. Stick to Recommended Procedure (top sticky). Don't expect perfection and you won't be disappointed.

Report crashes to Ulead Tech Support.

John,

You should add that as the first line of the Recommended Procedures.

With the proxy files I've created, that are less than 1GB, I find a faster response time. It appears to use less system resources and playback with various layers of flash and inserts is a lot smoother. So using a proxy is not a waste of time and it is not outside the established workflow. I'm using proxy defaults on files which the product's help says I can use. If I'm making numerous edits then the 3 - 5 seconds wait without using proxy files after I hit play can make the editing process painful.

And I know it won't improve picture quality, I never expected it to. I don't understand why what I'm doing seems to sound so ridiculous.

By the way, I tried to report it to Ulead technical support but the page gave an error when I submitted it. DOH. I'll try again tonight.

I appreciate everyone's responses but I'm really after a solution or hearing if someone else has seen this problem. I want to use the proxy this way becuase I've seen some measureable improvements.

I am not meaning to criticise your work flow -- if it works for you, then good.

But I feel I should note that since the AVI files you are dealing with are in fact DV/AVI files, then though they may indeed be large, they are the rock-standard files that VS was designed to handle with ease, even by relatively under-resourced computers. Indeed, this was a principal driving force for the development of the DV format in the first place. And certainly this was the case with earlier versions of VS, before smart proxy ever came along.

But as I say, if it works for you, then by all means use it. But I suspect that the only people you will find on this Board who ever use it are those dealing with HD files, not rock-standard DV ones...

No one is trying to make you feel/seem ridiculous. What we are saying is that Smart Proxy is for HD Video files.

Consider this. The current DVD disc format (single layer) is 4.3 GB and holds a hour of top quality normal video. The new Blue Ray / HD DVD disc format is 25GB. I think John (JCHunter) can tell us the capacity timewise of these new discs.

As for 'it's there so I can use it' is a bit like saying you can use a lorry to transport people from a bus stop. Yes you can but the journey will not be very comfortable.
