Motion Track an Image Until it's out of Frame without Keyframing?

StrawberryClorox wrote on 9/13/2018, 9:02 PM

Is there a way to use bezier masking to track an image/text until it goes out of frame? For example, if I had an image in the middle of my screen and I needed to pan upwards until it was completely out of frame. Right now it just tracks until the masked area is out of frame but then the image stays near the bottom of the screen during the rest of the transition and onward. Here's a video if I'm not explaining this very well:

I get that I could do this by keyframing but I need to pin dozens of points onto a map and return to those same points at a later time in the video. I'm using this script to pin the images: https://www.vegascreativesoftware.info/us/forum/beta-pin-image-video-to-motion-track--112837/

Thanks in advance.

Yes. If I understand what you want, it can be done and you are using the right script (the beta version of the PIP script) called "Copy Motion Track to PIP".

Hmm, then could you possibly look at what I'm doing wrong? Why is my pin being swept up by the side of the screen?

It's impossible to track when your tracking area is out of the video frame. You'd either need to manually add some keyframes or use a tracking area beside while offsetting the image attached.

I think Marco is right. You need to choose a tracking point so that the "pin" location will be off the screen BEFORE the tracking point stops at the edge.

I've encountered such problem before, but what I did is just animate another keyframes on the timeline motion tracker to move the "things" u tracking off the frames

I put the tracking point in a new spot where it doesn't move out of frame during the transition and the pin/image moves out of frame like I want it to. However, the pin remains out of frame when I pan back to the starting area but I need it to still be there.

The only solution to this issue that I can think of right now is to manually put a copy of the pin in it's original spot once it has to be back in frame but is there maybe an easier method? Like I mentioned in the original post, I need to put 30+ pins onto this map. I'm pretty new to this method of motion tracking so apologies for having to ask so many questions, and thanks for all the replies so far.

For your situation, that's what I would do. I'm not sure that "motion tracking" is what will work for you. Just use Photoshop of some other image editing software to "layer" all your pins into place as needed. If you don't want all the pins all the time, just use the same map background and you should easily be able to pop or fade pins in and out as needed once you have the correct map images with pins and without. Remember, pan/crop moves in Vegas can be exactly matched with "paste attributes".

Yeah that's exactly what I started doing but I just wondered if there would've been an easier method using just vegas. Oh well, thank you very much for all the tips though.
