Problem with a LARGE AVI

[N-Bomb]

Posting this for a friend...

--------------

I need to reencode a 5.55GB AVi I captured with VirtualDub. there were no errors, and everything went fine during the capture, only when I try to open it in Vdub, I get the error "Cannot determine file type of <filename". This is on a NTFS partition under Windows 2k. ANy ideas on how to make Vdub handle it?

Wierd? - especially since you said it was captured with vdub originally. I'll list some ideas, don't get insulted if they are obvious to you, just thinking aloud!

Does the file actrally have an .avi extension? - do a view-file types-show all files type thing to be sure

Is it a DV type file - there are two types ( type 1 and type 2) only one can be read by vdub as a regular avi - if this is the case there is a converter program to switch between the two. (vague memories only!)

Is the file on a networked computer/drive? vdub can have problems with this apparently - just transfer the file to the target machine or use vdub on the source files machine and process their. (don't ask me about frameserving from their - never done it yet)

I can't imagine that the file is corrupt as vdub should still recognose it as an avi, (grasping at straws!!)-> you could use divix to repair the avi idex or even try aviutl (a japanese vdub like prog which seems less sensitive to input files than vdub) - but i doubt these last 2 options will do anything.

Hope you get it sorted.

You can try to open the file through AviSynth frameserving. Use the "AviSource" or the "DirectShowSource" command. You may have to extract the audio to WAV and treat it separately.
