Slow-motion in VS8 begets foreign frames in rendered movie

Hi all,

I am struggling against an annoying bug in VideoStudio 8 (fully patched). I have used slow-mo for some of my shots that seem okay when previewing them inside my project. However, once i create a video file (AVI or MPG), three of my slow-mo shots start with a foreign frame. The latter always matches the last frame of the previous shot in my captured movie. The slow-mo shots have been slowed at 75% but not all of my shots slowed at the same speed show that bug.

I have also noticed that, when slowing clips inside the timeline, VideoStudio sometimes replaces the shot with the previous one from the captured movie. Reverting back to the original speed does not solve the problem and you have to remove the clip from the timeline and reinsert it.

Anybody ever has encountered this issue ?

Normal video is 30 frames per second and it is interlaced. To slow it down slower than 50%, Videostudio needs to extend the play of the frames. It only has those 30 frames to use. It might have something to do with that.

Hi Pad

Project playback is not all that accurate, the completed files will view better.

Are you sure you have cut the clip to the correct frame.
Expand the timeline to 1 Frame to view the individual frames at each end if your clip.

‘Zoom to icon’ Left of timeline rule.

AnimeChick : my video is shot in PAL so i have 25 fps. Anyway playing movie at 75% means it will be faster than 50% so VS should not have to extend any frames. By the way, i have slowed down one shot at 25% and it looks good.

trevor andrew : yeah i know finished shots look better than inside the project

and my clips are cut to the correct frame. I have finally decided to slow those shots at 50% and shortened them so they fit perfectly in the timeline (my shots are synchronized with music so i could not afford to alter their duration).

Thanks anyway. But it seems we might have a bug here...

Hi
I think you misunderstand me:-

When I said ‘Project playback’ I was referring to the timeline view and the white duration / time rule.
Not the Playback Speed.

To the left of the white rule are four buttons,

‘+’ (Plus) This will expand the timeline, watch the time scale change.

‘-‘ (Minus) This will contract the time scale.

Fit Project to timeline, Your total project will be contracted to fit the screen.

Zoom to ( this is probably the most useful)

Using these buttons you control what you see in the Timeline View.

You can view the very last frame in the clip to make sure it is what you want, and not an unwanted frame.

Sorry for the confusion.

Trevor
