Avisynth error: insufficient memory

[olivier]

Hello,
I try to make a huge slideshow of around 1000 photos and videos to burn on a DVD.
I use the great tool "DVD Slideshow GUI" to create the slideshow, then I export it to an AVS file.
The AVS file is quite big (1268 Ko). When I try to open it (via VirtualDubMod or Quenc), then I have an avisynth error about insufficient memory.
I could make 3 or 4 slideshows and avs files, encoding them then joining the mpeg files.
But is there another way to bypass insufficient memory with Avisynth ?
Is it possible to split an avs file ?
Thank you for your help!

That's a lot of pics, but you can try adding the following to the top of your AVS script:

SetMemoryMax(512)


or whatever # is 1/2 the amount of your installed RAM

Hello Soopafresh,
Thank you for your response.
I tried SetMemoryMax, but the same error occured...
I opened the task manager and I have seen that there is a bigger and bigger exchange file that is created when the avs file is loaded in VirtualDubMod. At one time, the exception is raised.
I have set the exchange file to the maximum allowed by Windows (4096 Mo), but the error raised at around 1.9 Go of the exchange file.
So I have a problem of virtual memory, even if it is set to max.
Any other hint/workaround ?
Thank you!

Post an extract from the beginning of your AVS file.
That may suggest the problem and hopefully solution.

Here it is
If you want, I have attached the avs file that is generated (1Mo)

EDIT: I just tried this app on 250 images - It used 560MB. I'm assuming you have 512MB of total RAM in your machine? Fuggedaboutit....

There has been talk of improving the memory handeling of avisynth. I hope they will succed with that. Until that happens I'll suggest that you export as mpg in smaller parts and then use something like MediaJoin, to join the files into one.

I had this problem too with high resolution photos.

Before running my avs script, I just resize all my photos with a height of 600 pixels and all was fine, 500 is ok for ntsc

It seems that avisynth is converting a jpeg to bmp in memory so a 6 megapixles photo takes a lot of memory.

Faced same problem, solution was adding at script begin:

SetMemoryMax(192)

Avisynth get 1/4 of total mem leaving little for processing, limiting it frees for the rest of the filters, etc, specially if using x32 windows were max usage mem per process is 2gb.
