Here is a screen capture from the source: http://imgur.com/hswLXEx Here is what it looks like in virtual dub (and what it looks like when I save the AVI): http://imgur.com/0e0YflZ To really see the affect focus on the green circle in the bottom right corner. Any thoughts? I'm using DXTORY to record the video and PIX Video Codec. |

| Fields are swapped -- use the field swap filter, or change options on the decoder if you've got a third party MJPEG decoder installed. This is due to a historical ambiguity in the way that fields are marked in MJPEG streams. IIRC, when the Microsoft MJPEG decoder came out, it was backwards to the way that everyone else was marking the fields, and that kind of made a mess. |
