Blurry Image after exporting

So my problem is that when inserting the finished image under the green screen, after changing the resolution to 1920x1080, the image is blurry. I set the tracks appropriately, then did the track data, then exported.
This problem occurs in Mocha Pro and even in Mocha AE.

Does anyone know what the problem could be?

So you are saying the render quality of the insert is blurry and you are exporting data to AE?
What size is your source graphic or clip for the insert?
Are you using Transform, Corner Pin or Corner bin w/Mo blur?
Have you pre-scaled or added any effects to your insert layer?
If you can share more, we can try and help.

So, original movie is 1920x1080. My precompose is 1920x1080 also which i already done.
On export option i used Corner pin with motion blur. As for the effects, I didn’t use anything except keylight for green screen.
I don’t know if it matters how i did the tracking point in mocha pro or not ?
I used reference points, then I used auto when changing perspective in movie.

Can you send a few screenshots to show your project? Please show the shot in the Mocha interface with the Surface tool showing. Also, show the after shot in After Effects.

If the shot is a long zoom and your surface tool is scaled very large, this could be related to your blurry issue.

So I am sending screenshots of the two previews in order to better show what blur was created here, plus the effects I used in the project. Here is only mocha pro and keylight. In addition, I am also sending screens from mocha pro how I set it all up. With this animation, there is a change of perspective quite often because it is difficult to keep track points and I have to set it myself sometimes.

If i didn’t send something, please write me, I am new to these matters, so it is possible that I did not understand something. I am sending screenshots below.

Btw how to delete black points which was on the green screen? I know it’s best to mask them, but the camera moves so the mask stays in place.

If someone know how to repair this i would like to refresh topic
