Windows 7 Successful Use of [AviSynth > AvsPmod > avs2avi]

Sunday, September 4th, 2011

Made a simple AviSynth script to get an existing real HDV video (in Cineform format) and apply TDeint (motion-compensated deinterlace filter) to it.  Opened it in AvsPmod and it displayed OK.  Exported the result of that processing from AvsPmod via [Tools > Save to AVI].  This called up avs2avi.exe.  That executable’s menu of codec formats was as below.  NOTE the Cineform codec (following that company’s takeover) now comes under the name GoPro – I missed it the first time I scanned!  The test worked fine – deinterlaced video successfully exported to Cineform and subsequently played in Windows Media Player.

  •  Microsoft Video 1 (an ancient format – as explained at http://en.wikipedia.org/wiki/Microsoft_Video_1)
  • Intel IYUV Codec (a very old format http://www.dvxuser.com/V6/showthread.php?178685-What-is-Intel-IYUV)
  • Intel IYUV Codec (again)
  • Cinepak Codec by Radius
  • proDAD Saver for Mercalli (not sure it’s a real codec, maybe a “virtual” one, associated with the proDAD video stabilization plugin for Sony Vegas)
  • GoPro-Cineform Codec v7.3.2 (CINEFORM)
  • ffdshow Video Codec (several choices, shown when you hit Config button)
  • Intel Indeo Video 4.5 (From the “good old days”, I used it back then to compress PAL standard definition video from analog capture)
  • Full Frames (Uncompressed)

AvsPmod and x264.exe

Sunday, September 4th, 2011

Playing with AvsPmod, tried the [Tools > Save to MP4] option.  It prompted for a path to x264.exe.  Searched for one on my system – but there was none.  Searched in this blog but, although I’ve downloaded it before, I obviously didn’t blog it.  Web-search etc revealed http://x264.nl/ where for my context and purposes the 32-bit app of 8-bit depth worked fine (the other variants did not)

avs2avi works fine under Windows 7 (W7)

Sunday, September 4th, 2011
  • Not sure why, but suddenly avs2avi.exe works fine on my W7 system.
    • Didn’t knowingly alter anything.
    • The only change I’m aware of is I uninstalled AviSynth 2.5.8 and installed AViSynth 2.5.7.
  • I’m using avs2avi as part of AvsPmod 2.2.0.
    • AvsPmod is itself in Compatibility Mode for WIndows XP-SP3 (otherwise it doesn’t work)
    • However I have not put avs2avi in compatibility mode.
  • It (avs2avi) works fine, both from AvsPmod and as standalone.
    • Just ensure it has write permission to its destination of course (no that wasn’t the problem before).

AviSynth’s AvsP and avs2avi under Windows 7

Saturday, September 3rd, 2011

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:
