Deinterlacing

I just want to clear some things up for myself:

I know you need to deinterlace video stills in a timeline, as to reduce flicker, but is it necessary to deinterlace photographs that have been scanned into the computer? I'm thinking not, but maybe I'm wrong.

And say you a video event down really slow -- should you apply a flicker/deinterlace filter? Kind of dumb questions, but...thanks.

Deinterlacing only needs to be used on sources that are interlaced. Since scanned-in still images are not interlaced they do not need to be deinterlaced. As you have stated, only a still image taken from interlaced video footage would need to be deinterlaced.

Don't confuse this with the Reduce interlace flicker option in Vegas which reduces the possibility of flicker when you interlace your media for output on TV. This should be added to still images that are scanned if you see them flicker while watching them on an interlaced TV monitor.

Blurring the still vertically can help reduce flicker. One of the de-interlace modes kind of does that (blend fields; set this under project properties)... so the end result happens to be similar.
