Artifacts and TMPGenc

[Dp1983]

I have a problem with dark parts or the blackness of my svcds. I think they are artifacts. Little spots in the blackness or shadowy scenes. Hard to explain. For those of you who use TMPGenc what do you do, or in my case, I am more interested in what I should not do in order to avoid artifacts on the screen. I always use 1:1 vga non-interlaced full-screen 2 Field Order A (I think I'm going to mess around with field orders ever since one of my projects was jerky).

Maybe I should check the erase video noise selection? The glossery states video noise can cause it. It also says mosquitoes and blocking. What are those?

So far I have one suggestion.

1. Try different media. (thanks tommyknocker)

Non-interlaced has no fields.

Your issues may be that you need to either check or uncheck the "Output YUV data as basic CCIR601..." -- You just missed a big discussion on that. Go find it with a forum search.

"However if you're converting, say, from another MPG or DV, these files are already clipped to 16-235 (and DVD rip DivXs? hence the gunky 'not-quite-blacks'?) so having it further compressed will mean your dynamic range could fall to say 30-210... in this case you want to enable the setting."

I got this from a post about it. So I want to enable the setting when converting from rip divx. Is there a sure fire way to know when and when not to use this setting?

Also is this problem known as ghosting? Cause I just noticed a ghost reduction setting. Maybe that in combination with noise reduction would help? With the quote above I'm starting to think that could be my problem though.

8) the ghost reduction setting is only used on scary movies
