[AseemAkram33958708q0dy]

When i export my video in any resolution so its objects are cracking from the corners, myart board size is 

1080 x 1920 so can anyone explain this issue. How can i get perfect video ?

are you selecting an mp4 after clicking file>export>export video/media?

Yes, sir, I want to show you screenshots.  This condition is before exporting the project 👇👇

And this is after exporting 👇👇

These glitches that you are getting, where the curves don't render properly upon export, are most likely because your artwork was created too small and scaled up a lot via camera or at symbol instance level.

To avoid this, go inside your symbols and scale up all your vector shapes.
