Hi

This question is not 100% about encoding, but then again it is!
It goes something like this:
I am thinking about building myself a htpc and for that I need a card for recording from my tv. Up untill now I have looked at Hauppages WinTV-PVR-250. To my luck a found a page where someone had uploaded samples of the different qualities which are available to record in. The page can be seen here: http://www.cask-of-amontillado.com/pvr_mpg.html

All the clips, execpt vcd, playback with "shadows", or not shadows (it's very hard to explain) it's more like the previous frame is not finished being drawn before the next frame is displayed, and causing some form of trailing shadow. I tried to get some friends to playback the same clips and they saw the same. I think I better mention that I playback the clips using PowerDVD (but also tried WinDVD, same result) and have no mpeg-card in my box.

The "funny" thing here, and also the reason why this has to do with encoding, is that if I convert a clip into XviD using AutoGK then there are no shadows at all, and the pictures is much better?!

Can anyone explain to me why this happens?

hi and welcome to the forum,

this effect you are seing there, is most likely "blending" - you remove it automatically by deinterlacing the clip with autogk (autogk chooses the parameters automatically, so you won't even notice it)


anyway, the cause for this most likely lies within your capturing, either some bad setting, or bad software used! maybe you can resolve this problem by changing the TFF/BFF flag!

Setting the deinterlacing to progressive in WinDVD solved the problem. Thank you!
