Any ideas? Working on a slide show thought I'd finished it looked at the final AVI and there are simmering pixels on the still images any one any idea how to solve this, against the clock so to speak :(

That's cause your JPEGs are higher than video resolution and not interlaced. So when you look at them in an interlaced video, you get line flickering.

Turning on ISS should fix it.

Or you could do a .5 pixel X/Y blur.

Either or both of these as needed.

cheers Eugene,
sorted it late last night ran the Defielding Filter twice on it and it seems to have worked. They were large format jpegs but I thought VT auto resizes them :confused:

They are auto resized, but if the resized image has a single pixel or horizontal row of pixels that interact with the scanlines of the video then you'll get the shimmering. One way to combat it, as Eugene says is to apply a light blur.
