Hi Michiel

Is it possible to run a picture and video layer together in such a way that one is visible sometimes and the other when it is not. I have tried your suggestion of moving a picture etc off-screen and tried keyframing the transparency but I have found it almost impossible to achieve a cut, rather than a dissolve, or to prevent the viewer seeing the layer shoot across the screen. I realise you normally need two keyframes for each stage in this type of setup but am I missing some easy way of doing it?

Will setting the keyframe interpolation to "No Animation" achieve what you're trying to do?

The slider on the timeline moves in rather large increments. to give an element a snap-in/snap-out or instant switch effect, set the keyframes manually. (Do this with the numbers on the top left of the timeline)

Let's say you want the effect to occur at timemark 00:01.000, you can use the slider to get close to that mark, but to make the change you'll have to type in the next marker in the time window there above the slider on the left. For example you want a picture to disapear at the one second mark. Set the time at 00:01.000 and place a keyframe. Then in the little window at the top left of the scroll bar, type in 00:01.001 then make the change to the transparency layer. Now the effect is instant. To get it to come back, let's say at 00:02.000, reverse the action. Set the timemarker to 00:01.999 and set a key frame. Then mannually type in 00:02.000 and re-adjust the layer.

If you are using an element that fills the display window, you can do this on the layer with the closest position. If doing it with something like text that you can see through, you'll have to set the keyframes on both layers at the same timemarks. I script most of the stuff I do and since you cant zoom into the timelime to seperate keyframes that close, I usually write those numbers down so I don't forget their exact position.

I actually use this a lot with camera angles, to give the illusion of multiple cameras. One of these days I'll talk Michiel into adding a zoom in feature to the timelime so we can seperate .001 changes. (HINT HINT WINK!!! LOL)

Hi Billy Jack

Thanks for the very quick and helpful response. This is more or less what I was trying to do but it may be much easier using your method! Yes, Michiel, we do need a timeline zoom!

Hi kf_daddy

I read Billy Jack's answer before yours but I had missed this feature and will try that - it sounds promising!

Thanks!

LOL I forgot all about the "No Animation". I usually want things to move after the switch so I completely spaced that.
