Zarx causing warping on bottom of video?

Postby dreamoflife02 » Fri Feb 05, 2010 9:51 pm

I've been tearing my hair out over this all day, hopefully someone knows what's up.

There's some examples of what I'm talking about-- the very bottom of the video, there's some really strange warping going on. It isn't there in the lossless encode, and it wasn't there when I encoded an ~80mb file at about a 3000 bitrate, but it's showing up now that I'm trying to get the file smaller. I'm doing 2-pass conversion with AVIsource, as directshowsource caused weird sync problems. Help?

800x368. The ORIGINAL original encode is 1280x720, I cropped letterboxing off the top and bottom and resized in VDubmod.

--And it is doing the same thing in a higher bitrate encode too, I just reencoded to check. I guess I must have missed that before.

Are you sure it's not a decoder problem, or a display device issue? Which H.264 decoder are you using (CoreAVC, ffdshow, DivX, etc.), and if you change the display mixer to another option in MPC (View->Options->Playback/Output section) does it go away?

I fixed it on my own-- I'd cropped some pixels off the side, too, and when I resized without doing that, it ended up fine in the end. (And I'm using ffdshow, if anyone else has the same problem.)
