Hello! Dont know if I posted in right thread, but hope its right.
I become desperate.

At work we recorded some video with Vdub. But when I want to play it or open for edit it with Vdub - I just cant.
In playback there is just black screen and audio.

System: win2k3, K-lite codec mega 6.50, video source was set right.
Settings in Vdub: http://i51.tinypic.com/2po3xnc.png

When I try to open: http://i55.tinypic.com/2127b09.png

I need this video badly, its from my work, and are needed to be sent to client.

I tried "OJOsoft total video converter", and some freeware tools, no help.

Any ideas or hints? Please help


upd: Tried to export image sequince. had this error: http://i53.tinypic.com/ncxxte.png

Did you check in the ffdshow vfw config that the h263 decoder is enabled ?

In ffdshow: http://i54.tinypic.com/29uocir.png
In vdub: http://i55.tinypic.com/28jcwew.png

Or I had to do that before capturing?

If I read you the error message in the first post correctly, I think you will have to redo the recording if possible. Apparently ffdshow allows encoding to formats it can't handle itself, which lays outside of VirtualDub's control.

Hmm, I thought the ffdshow decoder would handle that as it's labeled h263+, but it doesn't look like it

If you have a directshow h263+ codec installed, the directshow plugin *might* open it

How can I do that?

Get the DirectShow input plugin (link in my signature), and put it in the VDub plugins directory. Then open the file, but before you click open in the dialog select 'DirectShow input driver' from the file type dropdown list.

Before you do this you could do a quick test by opening the file in WMP to see if this would work.
