Problems opening DV-captured AVI in AviSynth

Hi, In an attempt to transfer the content from my mini-dv cassete to a CD, I got stuck when I tried to perform some additional processing of a captured avi file in my AviSynth script. When I try to open .avs file from VirtualDub, I get the 'unhandled exception' error message on the following (the only one) line in my script: DirectShowSource("c:\mydir\myfile.avi") The file opens correctly in MS Media Player. The avi file itself is captured using MS MovieMaker (I guess it means using MS DV codec). I also tried capture in Pinnacle Studio 8.1 (using both default and Mainconcept DV codecs), but with the same result. The environment: WinXP SP1, AviSynth 2.06, VirtualDub 1.4.10 (the camera is Sony DCR-PC8). The captured avi file is rather small (cca 100 MB). Does anyone have an idea what could be wrong? I thought that 'DirectShowSource' would open any file that MS Media Player can open, since it relies upon the same functionality. Or, perhaps I need to use specific DV codec in a specific way, and not just 'no-brain' MS MovieMaker capture? Thanks in advance!

Welcome to the forum, 1) Is it a type-1 or a type-2 dv avi? In the latter case you can try to open it with AviSOurce. 2) Try using an older version (say v2.04 or v1.07) of AviSynth.

Maybe a stupid question. Did you install a DV codec (like panasonic)? Information can be found on the faq in the DV forum.

You will need it. If you open VirtualDub and select video compression you will find a DV codec if you installed one (I guess you will find MainConcept codec in that list). Maybe you can try the panasonic DV encoder (see link in the DV faq).

For directshowsource() you need to include the framerate of the video since otherwise it won't know and it'll just get mad and error.

Because with AviSource your VfW codec will be used, whereas DirectShowSource (as the name implies) needs a DirectShow filter (.ax filename extension). bb
