I have some video footage of my subject very close up, looking through a telescope. There's a pretty obvious reflection of me in the lense of the telescope. How could I overlay a round image over the lense like it's the reflection (without the black of the rest of the screen surrounding the image)?
I show you step by step how to use the Track Matte in my book, if you're interested.
Basically, you put your background video on Video 1 and the video you want to appear in your telescope on Video 2, directly above it. Then, on Video 3, you open the Titler and use the Graphics tools to draw a white circle over the area of the video you want your telescope video to appear on.
You then create a keyframed animation, if necessary, so that this white dot follows the location of the telescope -- if this area moves around. If not, you don't need to.
Then you apply the Track Matte effect to the video on Video 2 and, in its Applied Effects, you set the Track Matte to use Video 3 as its matte.
Although, as I say, it's easier to show you in the book, with illustrations, than it is to describe it on this forum.
Crud. Thought I had figured the animation out, but it apparently didn't work. I set keyframe marker every frame, moved myl mask a bit & reduced the size via the BAsic 3D effect, but by the time I came to a stop and reviewd, the first frame matched the last frame I finished! ARrrgh! All that work for naught! What did I do wrong?
The camera begins to zoom out and the image inside the lense gets smaller. Now, I'm a little confused and I suspect I dont' have some things.right. My subject is on track 1. My view is on track two. I basically took the video and reduced it so it would fit into the space fo the lense.
When I origjnally drew th circle, it fit inside the brass ring. But I was noticing that when I turn off the track matte (admittedly, I may have had it in the wrong order), the circle is way bigger and off center and I don't know why. This is the end of the matt sequence, but as you can see the animation and shrinking did not work. So Im not sure in what order I should have created the animation and the matte. Should I be fittind the white circle to the lense, as opposed to the picture?
One last thing - was noticint the squiggle on the picture - is this the animation movement visualized? I watched a tutorial but wasn't real clear on how that's supposed to work. (Tried to upload a pic, but it didnt' show the squiggle)
I'm not sure what the tutorial advised you.
But, as I show you in my book, if you set up the white dot's position prior to adding the Track Matte, it should work.
Do note, however, that the white dot will look much bigger when you're in Title Adjustments than when your'e in the regular editing mode.
Make sure you're not in Title Adjustments when you set up the white dot size and location. Open Applied Effects and use Motion properties of Scale and Position.
I think you're doing a great job! It's a very cool effect!
Not sure whether I did or not, but I finally figured it out - although I forgot to flip my image first. Oh well. It was finally amatter of resizing my overlay more, and then making sure it was properly framed in the telescope before applying the animation. Thanks for your help. I will definitely pick up your book soon!
