[HELP] 264 is too small

Okay, there should be some error popups in that case.
-> What do they say? (Alternatively create a debug output level 9 when you press the Avisynth preview)
(Also as a side note: In case your content is not SD but HD or above I would recommend to use Vapoursynth and SVP and not Avisynth.)

the error popping up were
Avisynth preview error : script error: There is no function named 'SetMTMode'
Avisynth preview error Hybird\Hybrid\32bit\avisynthPlugins\ffms2.dll)

basically all errors on here been using this method but suddenly stopped working
