Cap in mpeg2, encode w/ autogk - how to put watermark?

[Epixinguinha]

I usually do my caps using Intervideo's WinDVR, maximum bitrate possible. I encode to Xvid using AutoGk. Result is a 700 Mb file. Now I want to add a watermark in it, without having to reencode the whole file - point: watermark is to last just the first 2 minutes or 3.000 frames.

Is there a way to do it? I tried Virtual Dub using the full processing mode (or you can't have the "FILTERS..." enabled) and I put the same bitrate as the main file. It came up with a slight difference (Xvid was 1925 kbps and the new one came with 1918 kbps - so Virtual Dub said it had different properties and it could not append one to another).

Any help? I just wouldn't like to give up my cap in mpeg-2... i know I could make it capping with Huffyuv and then encoding the whole thing with VDub. But it takes too much space and CPU, so I'd rather not doing it.

I'm afraid that if you want it done properly, quickly, easily, and of a high standard, you can't have your cake and eat it too

A cap to MPEG-2, then re-encode to DivX, then re-encode (again) to add a watermark is IMO very inefficient both time and quality-wise. IMO your second suggestion is the one to go. Cap to Huffyuv, Picvideo MJPEG (or even a DV codec if hard drive space is an issue) then add your watermark and re-encode to DivX. If you don't have enough hard drive space, then get some more, I say

Yeah, I see... Well, you can't have it all. I'll try the 2nd option. Thanks for your answer Jim.[/quote]
