Thanks for the reply. Yes, I am referring to the renderd clip. I have Vegas 5 on two of my PCs--one running Windows 2000 and the other XP Professional. I get the same results from both. I am editing hunting videos and action shots such as a turkey taking flight renders great slo mo in MS 3 but very poor (jerky) in Vegas. This is certainly not a show stopper for me but it would be nice to get the same quality from Vegas. I thought maybe there was a setting that I may be overlooking. Having said that I love working with MS 3 and Vegas.

Well, I just took a 14 second .AVI file and brought it into both Movie Studio 3b and Vegas 5d (build 194). I dropped the .AVI file onto the timeline twice. The first was at normal speed and the second slowed down as much as possible. I did it this way so I could watch the normal video immediately followed by the slow motion video. Then it was rendered out to .WMV format.

When played back, both the MS 3 and Vegas 5 .WMV files appeared to be the same. I did not notice any jerkiness or anthing strange at all.

Not sure if this helps or not, since I could not duplicate your problem. Hope someone else can shed some light on your problem.

Oh yeah, Vegas 5 and MS 3 are installed on the same PC.

Good luck...

Did your sample test contain a lot of movement or was it just a normall low action clip? Normal video slowed downed seems to work O.K. in Vegas, but high action video degrades and becomes jerky while the same clip works great in MS. I used the turkey taking to flight as an example due to the rapid wingbeat--really jerky in this instance in Vegas, but looks great in MS. Thanks for your help. I will continue to experiment and will post if I find a resolution.

I know this doesn't account for the difference in the two programs, but how much are you slowing your video down?

As I'm sure you know, video is actually ~30 still images per second which, because of persistence of vision, our eyes see as movement. You can slow it down a little without much effect, but eventually you're going to get to a point of jerkiness (probably just below 15 frames per second or half speed) in which the frames are changing so slowly that your eyes can detect them.

That doesn't entirely answer your question, but it's something to consider.

The clip consisted of:
- Golfer walks up and drops a ball
- Another person starts walking into the shot
- Golfer swings the club and hits the ball
- The ball speeds off and beans the other person in the head
- The other person falls down
- The golfer shrugs and walks off

It was obviously a staged shot as the golfer doesn't actually hit the ball he drops, but it is pretty funny to watch. Not a huge amount of action, but it isn't completely static either.

Now, when I slowed down the video clip, I did it to the maximum that Sony would allow. The 14 second clip stretched out to almost a minute in length, so that would be a quarter speed and it still appeared okay visually.

For real slow motion in film, the camera would run at a faster frame rate while filming thereby giving slow motion when played at normal speed. I don't know if Sony does any averaging of frames when slowing down the video clip or if it just doubles or triples the length of a given frame in order to give the appearance of slow motion.
