interlace filter

The Vegas Manual defines the Interlace Filter as:

This switch can be useful in cases where the source material didn't originate as video and contains extremely high spatial or temporal frequencies.

When you watch the rendered (interlaced) output on video of this sort of media, you may see flickering or crawling edges if this switch is not applied.

By high temporal and spatial frequencies, are they implying that the source material either have a resolution greater than 720x480 or frame rate greater than 30fps?

I just want to get a handle on when I should turn this feature on.

Tbis filter has been a great tool to me.

If you are using still photo's, it is especially useful. Some of my stills were jittering around, but after I selected this switch, all was calm and smooth.

Thank you all for your good suggestions..

Would any of you say there is ever a case where Interlace Filter would *hurt*?

Probably my best suggestion to you is, "try it". Make sure you continue the experiment all the way to it's final destination though, as the interlace filter may have different effects depending on whether your output is multimedia on the computer screen or output to tape and viewed on a TV. But still try it anyway. If a particular clip looks better with it, then use it. If it looks better without it, then don't use it.
