Best Way To Add A Thumbnail to an AVI?

[Teleri]

Heya folks,

I've tried searching past threads and didnt find anything that related to this. Some came close, but not quite.

If I'm just wanting to add 1 frame to the beginning of an AVI are there any good filters for virtualdub to do this? Right now I am using an awkward method of selecting 6 frames from DVD2AVI then using Virtualdub to select 1 frame of video. After that I use Windows Media Player to "record" some dead air.

Are there any easier ways of doing this or is this the best way?

Someone told me that there was a filter for Virtualdub but I havent been able to locate anything for thumbnails.

Second Question:
What is a good program to merge VOB's? There is quite a list, but I'd like something that everybody here tends to use.

If I understand correctly, you want to insert 1 frame from somewhere in the video at the beginning. The best i can think of to do this would be with avisynth, something like

clip1 = your source
clip2 = clip1.Trim(X,X+1)
clip2+clip1

I'm assuming you will process the audio separately, and you'll need to delay it by 1 frame to compensate.

If you really want to do it with vdub and don't mind losing the first frame of the video, you could use the logo filter to overlay a .bmp of the frame. This would avoid any audio sync issues.
