Is there a way (using VDub or other), to insert a watermark in several parts of an .avi file (e.g. a logo appearing every ten minutes with a duration of 10 seconds), so that I only have to reencode those parts where the watermark goes, leaving untouched the rest of the file?
Having to reencode large portions of a video that haven't even been touched sounds kinda silly to me...
I did a search but find no answers to this particular question.
Thanks in advance.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

You can do it in VirtualDub by splitting the file into parts. Direct Stream copy the parts without the logo. Reencode the parts with the logo (same codec, similar settings). Then append them all together.

Thank you very much for your help. -
In VirtualDub, if you use the logo filter with 'blending' and Smart Rendering, would that not limit the encoding to the parts with the logo?

In that case, it does know that the filter has no effect on those frames. Note that Smart Rendering is a different mode from Direct Stream Copy - in the latter, the filter chain is completely switched off.

Use Videostudio X2 Pro. You just add an overlay(containing your watermark-with desired duration) to any places you want on the overlay track. You can lighten the watermark, if you desire using the transparency slider. Quick and simple, unlike VD.

Now that is important: this problem only happens when I check 'Smart Render' option. But skipping that option will cause the whole video to be reencoded which is exactly what I donīt want.
