Bizarre Behavior Involving a Jittery Picture and Question How SB Handles Events

I noticed that certain section of a DVD I am making seemed a little jittery. It's almost as if the FPS was 15 fps or so. On this particular event I have an overlay that I crossfade to.

I checked the original source tape and the capture AVI and it looks fine.

I then dragged the same clip onto the timeline to create another instance of the clip. The "skipping" is not on the second instance of the clip.

So basically I have two events on the timeline using the same AVI as their source, yet they are rendering differently.

I am assuming that when you drag a clip onto the timeline Screenblast just creates a pointer/reference to the original clip and does not create a new file for each event.

Is that correct ?

Is there any way to "refresh" the timeline to rebuild the "jittery" clip ?

Is it jittery in your final output or are you just seeing it look sluggish on the timeline?

Remember that when you're watching a clip with an effect or an overlay or a transition on it on your timeline, you're only watching a "soft" render, so it may well look funny.

Try outputting just that segment as an AVI and seeing if it's still jittery. Most likely it will look fine once you've given it a "hard" render.

And, once you've created the AVI, you can replace that segment on your timeline with it and it won't look jittery even on preview!

It was jittery on the timeline and final output.

I was able to find a work around by dragging the source AVI from the resource pool again. Of course though other clips are jittering in my test press DVD. It doesn't seem to make sense.

I've no idea what could be causing this, but you could try renaming the source folder of your sources. MS will then prompt you for the new location when you open the project. It might have the same effect as re-importing.

I'll give that a try. After I corrected ACT2 of my movie I did another test burn and noticed that a few scenes from Act1 were jittery. It almost seems like the video is at 15fps.

I had captured 2 40 min clips, one for the first act and one for the second act of a show. For songs that had bad performances I also captured clips of that specific song from another nights performance. To insert the good footage I deleted the scene without ripple turned and and then I just dragged the alternate clip into the timeline.

It seems like the method I have to use is to actually drag two instances of Act1 onto the timeline, do some heavy trimming so they "sandwich" the corrected clip. As I explained above it doesn't make sense that I should have to do it this way.

I just got dome with another test burn and I'll see how it looks.

On the plus side I really love this software. For the most part it is rock solid and has a lot of flexibility for completing tasks.
