The context (AviSynth>AvsP>avs2avi):
- The AviSynth greater community has developed a number of applications to simplify the development and use of AviSynth command-scripts. One of these is AvsP, an AviSynth-script editor, has an option [Tools > Save using avs2avi].
- Under Windows XP, this prompts for a location then prompts (in a separate popup) for codec details, then AviSynth renders (via avs2avi) to the required output-file.
- There is a step-by-step tutorial at http://www.animemusicvideos.org/guides/avtech3/amvapp-avisynth.html
A problem (works under XP but not W7):
- Under Windows 7 Pro 64-bit (which can also run 32-bit apps), avs2avi merely produces an error message: <<AVIFileOpen failed, unable to open “f:\tmp.avs” : The operation completed successfully.>> The last bit (“successfully”) merely indicates that the application (avs2avi) does not make a very thorough successfulness-check!
- This issue was previously encountered & investigated back in March 2011: http://blog.davidesp.com/archives/247
Searching for a solution:
- Experiments, unsuccessful:
- After much web-trawling, I discovered a new version of AvsP, called AvsP(mod). But it made no difference – same problem.
- Next I tried running avs2.exe on its own, both with and without Compatibility mode enabled. As well as XP-SP3 (which caused a further problem), I tried even older modes (that didn’t). But no joy, the same error message was obtained.
- I downloaded the latest version of avs2avi and also I tried the one that comes bundled with AvsP(mod), in its Tools folder,but again, no difference.
- Asking for advice:
- Finally I sent an email to avs2avi’s main author, Moitah
- Also I posted a question to the Sony Vegas forum: http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=775793

- I have previously used that successfully on Windows XP-SP3 into Sony Vegas.
- BUT on Windows 7 its installation failed – obsolete installer.
