Opening large Huffyuv AVI files suddenly is crashing VS8,9

The file crashing is uvipp.dll. I have worked with large (120GB+) Huffyuv files before with no problems. The one I've got currently is 60GB. But now suddenly, Videostudio 8 and 9 both are crashing on me if I try to open a large Huffyuv avi file. I tried a fresh reinstall of Videostudio 8 - still doesn't work.

VS8 works just fine though with a 1.5GB XviD encoded file.

Specs:
WinXP Pro SP2
Huffyuv 2.1.1
Videostudio 8, 9 - patched or unpatched, same thing

So why's it crashing on me now, but never before?

Update - looks like it might be the file. Don't know why, I've done this procedure quite a number of times before - MPEG2 -> VFAPI codec -> Huffyuv -> Videostudio. It's always worked just fine. Odd.
I'll try transcoding it to the MSU Lossless codec. Maybe that'll work.

Have you tried turning on the "Enable full size output buffer" option, or possibly using V2.2.0? You can get the newer version here.

I tried that version of Huffyuv. When it actually didn't crash on me in Virtualdub, the output was totally garbled and useless.

And that Enable Full Size Output Buffer - where is that? Is it in Videostudio, or what?

I've been using V2.2.0 for a long time, and it has never given me any problems.

Anyway, after selecting Huffyuv as the codec to use for your AVI file, click on the Options button -- the checkbox for the "Enable full size output buffer" option should be in the dialog that is displayed next.

I'm afraid I haven't got that option.

Odd thing is, I've been using v2.1.1 for a long time without any problems. I just don't know why it'd suddenly stop working like this.

Ok, update time:
It works on a 55GB file that I previously worked on. Two things different:

File that doesn't work:
- dimensions are 622x384
- Is on a single drive
- HOWEVER, a small, 120MB clip of this file does load fine - same dimensions, same drive

File that does work:
- more standard 720x480
- is on a RAID 5 array, which probably doesn't have any effect, but who knows, it might

Update

It sort of has something to do with the size of the file, but then it might not. Dimensions, I mean.
A file that opens is 702x384, but it wasn't the 16:9 aspect ratio. The file is Huffyuv.
So I opened it with Virtualdub, resized it to 682x384 - 16:9 ratio. Saved it, also to Huffyuv. Videostudio crashes when it tries to open it. The width is the ONLY difference.
Being divisible by 8, 16, whatever isn't important - I've opened files 852 and 854 pixels wide in Videostudio already, and it didn't complain a bit.
Why does it hate this particular video so much?

I doubt it's the dimensions since you can open up smaller files with the same attributes.

Does UVS crash immediately upon opening the file, or only later on while working with the file? Can the file be played with Windows Media Player without crashing?

What happens:
With the file selected, I click Open.
The hard drive churns for awhile; Task Manager shows the vstudio.exe reads maybe 20MB of the file - then it crashes. It never does actually open the file.

What does Windows Explorer do when you click on the file? What about Windows Media Player?

Explorer doesn't seem to care - it only goes nuts if I have a corrupt Divx/Xvid file.
Media Player opens it and plays it, but it's always garbled - always has been for ANY Huffyuv file. However, Virtualdub, Videostudio, etc - everything else plays the same file just fine. So the file seems to be just fine.

This ancient thread is coming back from the dead.
The problem has resurfaced for no explained reason.

I recently did an upgrade and reinstall of Windows and all applications. I had edited a few videos in the meantime, using a similar method to the old one, only now I use AVISynth to flush out MPEG2 to Virtualdub - and to make use of MVBob's decent deinterlacing capabilities. Then I pass the Huffyuv file to Videostudio for editing.

Well, VS8 and VS9 both suddenly started crashing on me again. I use VS8 for editing, because VS9 clips the video a frame or two away from where I set the cut points. VS9's main use is its 2-pass MPEG2 encoding.

But it's the same as before - a small file of only a few hundred megabytes opens just fine, but a larger one crashes the program, courtesy of uvipla6.dll. One thing odd that I notice:
When I select the small file and select Info, the bitrate is shown correctly: 14723.97kbps.
But when I do this for the large file, the bitrate is reported as 1340.86kbps, which is most definitely incorrect.

This problem also occurs with the latest version of Lagarith. Why is Videostudio barfing when it tries to open these large files?
