Greetings –
I have searched this forum for posts regarding this issue but not found any so I will post it here. I hope someone with will be able to offer a solution. I hope there is a simple "change your____setting" for this!

This has to do with using masks, I’ll describe it as follows:

• I put an image or video clip on the timeline. For discussion, lets say it is 8 seconds long.


• I put a photo on the timeline below it of the same duration and mask part of it so the underlying image/video shows through (the issue is the same using still images or videos underneath the masked image)


• After getting that done and clicking ‘ok” the problem arises. The first couple of seconds of the masked “overlay” image just disappear. There is nothing there, all that is visible is the underlying image for 2 +/- seconds.

I have tried:

• Stretching my overlay/masked image left on the time line for an amount of time equal to the blank section in hopes that when it does start to show it will be visible when it is needed at the start of the underlying clip. No luck, the blank section just starts 2+/- seconds earlier and is now 4+/- seconds long, still not masking the clip it is supposed to cover until the same point in the timeline 2+/- seconds after the start of the underlying clip.


• Outside of PD, saving the two clips with new file names and using those instead of the ones I was using.


• Starting a whole new project just using the two clips involved. Same problem.


• Starting a whole new project using just new re-named clip files. No luck there either.

My thinking on starting a new project with the 2 clips only was I could make a separate video of them, then insert it into the larger overall video I am working on.

I am grateful for this place I can ask about things like this and really appreciate any suggestions others may offer. Thanks in advance!
