I need to hardsub some signs in a video RAW. I tracked signs with mocha after effect and then exported and edited in Aegisub subtitle editor.
In video preview, everything is OK.
But when I hardsub the sign using xvid4psp, the output signs have a shake effect.
Unlike the preview,in the output the moving signs are not fluid. They shake with no reason.
Could you please tell me why and how can I fix this problem? Thank you
