Heya,

so I recently started to make some basic effects in Aegisub and I seem to have found a problem that I am not able to resolve alone...

The thing is, whenever i use \t command for font enlarging (e.g. from \fs90 to \t(0,1000,\fs95) -> increase font size from 90 to 95 in 1 second) the result encoded video seem to be glitchy in that part of the video... What I mean is that that single line isn't reacting as it appears inside aegisub's video preview - the text is enlarging, yes, however it isn't smooth.

Note that I encode using Handbrake h264x at 15RF and Slow encode pattern to decrease final video size.

I'll post anything in gif form over gyazo, if you request it . for now here it is how it should look and how it looks.

P.S.: Ignore the inside-aegisub view... Even through I have 8 core AMD and 32 GB RAM, the program itself is only 32-bit so it doesn't have enough power to render it fully inside.
