de-interlacing VX2000/PD150 footage? at DVinfo.net

Okay, no doubt a stupid question for those who know a little bit more than me....

I have a Canon GL2 and I edit my footage on a PC in Vegas Video.

I always shoot in Frame mode.

This means that any frame I see in Vegas is not interlaced, but a full frame, which means I can frame-grab anything

Whereas when I edit footage from my friend's PD150 shot in 60i most of the frames are fields, that is they have interlace relics. Some of them look like full frames, maybe because there's no subject movement.

But how does one normally de-interlace their 60i footage so that they can frame-grab anything and it's a full frame?

Thanks for any info, general or specific, on this topic.

If there is motion in the image, and you only need a framegrab, get the frame you want and comvert it into a .bmp file. Take it in Photoshop (or simular), use "deinterlace". This is a simple way for deinterlacing (field interpolation or line doubling) which reduces vertical resolution because only one field is actually being used (the other is an interpolated or repeated one). More sofisticated systems with better resolution are based on motion and edge detection and are motion adaptive.
