I am trying to figure out why some transitions in the overlay track just affect the overlay ( ie a background on the video track with a picture on the overlay track..... followed by another picture on the overlay track with the same background on the video track) - If I select a WIPE transition or a Cross Fade - the transiton effects what is on the overlay track only...however if I select any other transitions it seems to move the background on the video track with the picture on the overlay track. The picture on the overlay track is essentially a picture in picture....

They were nice enought to grant our wish of transtions on the overlay track but I'm not sure it's set up to be all that useful or consistent!

I think an additional video track would probably be more useful for the effects that I'd like to create!

Has anyone been using transitions on the overlay track and have suggestions on how to best use the utility?

I'm sorry, I don't understand what you are trying to explain.

HI Ilene...

If you have two items in the overlay track and you wish to add a transition btween them I don;t quite understand why you have an item in the video track...

Overlay IS a Pic in Pic effect

But to answer your question, the transition has an Alpha Channel (much like a Chroma Key) so is in effect transperant...and that's why yu can see the background

sorry - let me try to explain it better...


lets say I put a 10 second color clip - blue for instance in the video track

then on the overaly track 1, I insert 2 jpgs, images,3-4 seconds each, adjacent to each other. I set the images to lie in the center of the Blue color clip on the video track, so that it looks like the blue is a matte for the pictures. Then I put a transition between the 2 jpgs.....
I am finding that with some transitions - ie the WIPE category of transitions or FX cross fade that the transition will just take place between the two images....the blue background screen in unaffected. HOWEVER if I chose SLIDE or any of the other transition categories, the blue screen transitions off with the picture....ie the entire screen moves versus just what is in the overlay.

I don't always want it to work this way - and rather prefer that the transition just affect what is on the overlay track and not what is on the video track.

Does this make more sense?

thanks.

Thanks Clevo - but I like whats on the video track to act as a background for the pictures on the overlay track...I often use interesting video backgrounds and it's just more visually interesting when my images or video are not always "Full screen"....

I would like to keep the what is on the video track as a constant and just be able to move things not just in, out,up, down, as we've been able to do until now...but to also use transitions between the images. ( i work w a lot of still images....)

Thanks for the clarification. I see what you mean with some of the Slide transitions. One that produces the effect is Slide>Diagonal. However, some of the Slide transitions work fine. Why? I don't know.

I guess you are just going to have to pick and choose which transitions work the way you want them to.

I understand what you mean now...

I still think it's an alpha channel trickery...

and there is no way in VS to manipulate the alpha channel, right?

Not for the transitions.

how else can you manipulate alpha channel - just through chroma key on overlay??

As far as I know.
