virtual dub error... can't save avi

[sunchaser]

hi guys,
i am trying to run some tests with different compression codecs and settings in virtual dub to find out which one gives the best results for converting my backup dvd video to .avi for editing in premier.

i have the avs file opened in virtual dub. i have set in and out points for a 10 second clip. When i try to save as .avi i get the following error:

unable to open file "c:\....test.avi" for write :The process cannot access the file because it is being used by another process.

whats this about? i tried a bunch of codecs and i also tried saving as old format avi and segmented avi. can you help me?

also, have you done any tests to determine the best quality codec for converting dvd video back to .avi video for editing? (i know about rule 12, but i'm not asking about opinions...i'm asking about facts or new products i might not be aware of)

thanks a lot for your 2 cents or five bucks
chase :confused:

Post your Avisynth script.

I'll take a wild guess... Your script has AVISource("test.avi") and you're trying to write to the same file in VirtualDub.

part2.avs ->

LoadPlugin("C:\Documents and Settings\max\Desktop\dgmpgdec143\DGDecode.dll")
MPEG2Source("part2.d2v")

since you are going to overwrite the file, you might as well try to delete it in explorer first.

i tried over writing it and deleting it but neither worked. each time i got this error.

then something has a handle open on your file... do you use thumbnail view in explorer?

What happens if you just try changing the file name?

[sunchaser]

i don't use thumbnail view and i've tried changing the file name as well as the file directory...

it was because i was using the last version of vertual dub.
now that i downloaded the .10 instead of the .5 it works...
