Forcing Key Frames Everywhere?

I have a moving object following tracking data from Mocha. It works well but in some frames the object needs its position adjusted. However, such changes affect neighboring frames unless there are key frames. Most frames however don't currently have key frames though.

How can I make changes in position of an object without affecting neighboring frames? Can I somehow force key frames on every frame? That should do it, I think.

Thanks.

If you are tracking in Mocha you should perfect the track in Mocha, not back in AE.

Tracking and Corner Pin keyframes are generated for every frame that is tracked when you use Mocha.

I have a strong feeling that you are experiencing user error caused by a lack of understanding and research on the process. More than half of the shots that I process in AE require some kind of tracking and I do not have any problems fixing up or adjusting a track. In order for us to give you any more detailed advice than check out the Mocha tutorials on the Boris FX website, we'll need a complete workflow description and a screenshot of your project with the modified properties of the layers that are giving you problems revealed. Just select the layer(s), press the U key twice, PrintScreen and paste to the forum.

Thanks, but not sure your idea would work, as I can't tell if the object is lined up properly until I check in AE. I can't keep going back and forth between Mocha and AE, especially since I have to close Mocha in order to work in AE. Also, the object is complex, and I don't think a corner pin works in this instance, especially since parts of the object are covered off and on. And the object I am using to replace the other with is almost, but not quite, of the same dimensions.

I wish I could post a screenshot or work flow, but the video is not mine and I don't have permission to post.

i thought I explained things well, an object sitting on top of a bottom layer, back plate, and just using the mouse to position, size, and orientate the object.

Thanks much.

you should do all the work in Mocha, including adjusting the track if needed. if you need an object to place to see if things line up, you can insert an object right in Mocha to see that it is in place. if there is a drift, you can try tracking again with more careful planning, or use holdout mattes or what not, or you could use the adjust track module. when you are back in Ae, it's supposed to be perfect and leave you only with the compositing part of the process, not the match moving.

I would follow Rick's suggestion about learning more about Mocha on the Boris fx website. it will clear things up for you.
