AE field issues
Hey, I’m moving and scaling a video clip within a frame, and rendering out in fields. There are some issues with playback: fields seem to somehow get swapped. I’ve heard that the video should stay on the even lines, but if I animate a frame moving up or down, the lines seem to switch fields or something. Anyone deal with this issue before?

Did you separate the fields when you imported the clip? Select the clip in the Project window and from the FILE menu choose INTERPRET FOOTAGE, then select either Upper or Lower Field First from the Fields and Pulldown section.

Well, the issue is this: When I interpret the fields to seperate (lower first), I see that the render goes soft intermittently, as though it is mistaking the interpolated field for the actual field on some parts.
AE renders very clear when I don’t interpret the fields, but moving areas in the image look like the fields are inaccurate, with visible interlacing even when played on a ntsc monitor. -
Okay. Are you sure the original footage is lower field first? If not you can check this by 2x clicking on the file in the Project window (with the Option (Alt on PC) key held down), this will open the footage window. Go to a part of the footage that has some movement and Command (Control on PC) click the right arrow key on the keyboard. If the interpretation is correct the footage will move forward each press. If the interpretation is incorrect the footage will jump back on one frame then forward on the next. Once you have determined the field order you must render using the same field order. Does that help?

Well, it seems that the field order is correct. The problem does not happen to video that is just centered in the composition, only to video that has an animated position or anchor point.
