I'm trying to mimick a VHS tape filter to use on a gameplay mod. The given effect should look like this while playing:

Problem is, i have done all the animation screens ready to be added. i set them as fonts in FONTDEFS and set them as "printbold" messages on ACS
in order to appear to the screen, but they only appear in a way smaller scale than the video resolution.
any tips on how i could make it look bigger that it could at least cover the entire screen??
