VDub newbie question

[weshuang]

This is a stupid question, but I'm just trying to learn VDub to solve a specific problem. I have some DV footage where the operator kept rotating the camera 90 degrees, like taking landscape and portrait photos. In order to somewhat correct this, I have been trying to use VDub since it has a rotate filter.

My question is, now that I have gotten Vdub to open the avi (which took a little while), I can't figure out how to just apply the filter to certain segments of the clip rather than the whole clip. I have been looking for the last couple of hours through various FAQs and forum questions, but I think this is too elementary a problem.

Can someone help?

You will have to split the avi file up using the virtual dub source range feature. Apply the filter to each segment requiring it, save, then join all the avi files together using the "append avi segment" feature. You could also use avisyth to write a script but that's more advanced and I don't remember how to do it!

Thanks, Kareem! I was hoping that wasn't the answer, but at least I can stop fooling around looking for options that don't exist in VDub.
