bumps on keyed stills

is there a way to illiminate bumpy/glitchy motion which sometimes
occures on my keyed still images?

i've been making some photo videos using high quality JPEGS in vegas 10.....I have my project set to standard widescreen settings and render out to MPEG 2 with the best settings......some of my pics, when keyed, tend to have some jerky motion on them......

any advice to avoid this?

ALSO, does anyone know about the glitch created by keying images with added borders? In other words, if you right click a jpeg, add a border and then key it to give it extensive motion, occacionaly, you'll see the border flicker on edges of the monitor where it's not even in the same position as the picture.......this might not sound so clear, but if you've experienced it, you'll lknow what i'm talking about.......any fixes for this? i think its a program glitch ----both version 9 and 10 do it.........

THANKS FOR FEEDBACK......

Hey dvideo2

Forgive my ignorance, not sure what you mean by "when keyed". Are you talking about Chroma Keying?

Check your interpolation curves.

i've seen weirdnesses with Vegas when using keyframes in the Pan/Crop window and experienced this for longer than version 9/10.

the most common problem i've had is when there's more than 2 keyframes, each with motion: when u remove some of the middle keys, the motion between the keys before/after sometimes gets a little bump where the removed keyframe had existed, as if Vegas hasn't quite forgotten.

closing/re-opening the project doesn't get rid of it; whenever this happens i've had to duplicate the clip and create new keyframes by copy/pasting the ones from the glitched versions to the correct position on the new clip's pan/crop timeline. sigh.

sometimes the pop is subtle and can be ignored... it's easiest to spot if there's 0% smoothing and the keyframes are set to linear... but no amount of smoothing completely gets rid of it and its still there if you revert to linear.

dunno if its related, but thought i'd mention anyway.

yea, it's in the KEYFRAMING.............i've tried different options
with smooting, liner, ......nothing seems to get rid of these
unpredictable glitchy bumps.....

any other advice?
thanks...

Vegas Keyframe Interpolation Envelopes is an excellent tutorial that helps to explain this sometimes tricky subject.
