.png jitter blues

I mix stills with video in Vegas... and recently after I render out segments the .png or .jpg pictures jitter when I see them on the monitor.... this hasn't always happened ..
... does anyone know what factors might contribute to this jitter look of these stills ..
I appreciate any input ..

I'm just doing exactly that, what is the 'jitter' like? I haven't seen any although I've had other issues.

Are the stills stationary?

For the duration that the still is on the time line there is a kind of shaking or jitter look to the still picture on play back even after rendering out to a new .avi

I've had a still of a trombone player, where on renderering, the still resulted in the player continuing to "play" or trombone his tubes in and out! Reeeaallly weird!!! - Nice "effect" if that's what you wanted - I didn't.

Grazie

Then it wasn't a "still" was it :)

Do you have any pan and crop set anywhere that could make the still move ever so slightly? If the still is at native res that would cause a lot of jitter. I'd ty looking at it frame by frame very carefuly to see whats moving.

Have you tried right-clicking on the .png in the timeline, selecting 'Properties' and checking 'Reduce interlace flicker'?

Try going into Project Properties and setting "Full resolution rendering quality" to "Best" instead of "Good". This uses a better downscaling algorthm that will reduce flickering caused by scaling artifacts. That should fix it. If you want to soften the picture, apply 0.002 or 0.003 of Gaussian Blur to it.

Thanks a bunch sdmoore... SonicDennis... I must have unknowingly had the Project Properties set to "good" (default) because setting it to "Best" it looks great... I applied the 'Reduce interlace flicker' just for good measure .....a new setting to me that I plan on experimenting with...... thanks again
