ATI Cap - Interlaced Video Jitters

JeromeERome · 9th June 2003, 13:55

OK I have an ATI AIW 7500 which I use to capture from my DirecTV via S-Video cable. From most of the posts I have read on here everyone recommends to capture as an interlaced format, not deinterlaced, for viewing on TV. My problem is that when I capture as interlaced my video is sharp and clear for most scenes that don't have motion. Once the camera pans horizontally or vertically, or there is a lot of motion on the screen at once I experience jitters, or tearing of the video. Its like I can see half of the scan lines and they arent keeping up with the motion. Its hard to explain I guess. Maybe someone knows what Im talking about. It only happens when I watch it on TV. It looks fine on the PC. I use MMC8.5 with my own custom settings as follows. MPEG-2 SVCD, 480x480, Encode Interlaced, 48k 16bit audio, PFrames=4, BFrames=2, VBR min 3.15m max 9.4m, motion estimation quality 100, Video Soap filter= Sports-High Motion, Combo Filter 1 @ 60%. I have been told that this occurs when the field order is wrong. However, I see no way to change that option inside the MMC8.5 software. Anyone have any suggestions?
