Interlace Lines

Hi Kids -

This may have more to do with my cheapie camcorder (Sony HC40) but was wondering if anyone could point me in the right direction.

I filmed some folks outdoors - some fast motion, some average - and the video looks fine when I use the full screen. However, if I zoom in the frame on the event, even a little, it seems that there are interlace lines in various locations and on various objects but not the full frame! And the more I zoom the worse it becomes.

Anyone have an idea on why that happens and how to avoid in the future?

Thanks.

Bruce

Try changing the preview to Best - Full.
What you're seeing shouldn't be in the final render either way, just that the preview is doing a quick and dirty render.

It is my experience that any time you are resizing interlaced video you need to choose a deinterlace method in the file properties. This is true even when you are outputting interlaced video and you don't want to actually deinterlace. Anyway, choose a blend fields or interpolate method of deinterlace and you can zoom in a little, but don't try to go in too much. The more you zoom the more resolution you loose, and SD doesn't have much resolution to begin with.

Ok - More info

I am using Best Full when I render and I am seeing this in the final WMV and MPEG-1 and MPEG-2 output. I have my project properties set to Progressive as well (although wouldn't the output option decide that for me?).

Thanks for the suggestions - This is just really annoying more than earth shattering (I just don't get tighter in post).

Thanks.
