encoded ASS subtitle into video by Hybrid got a different effect with original

[ssdde]

look at this pic, the upper part is the best,   is correct,    is the original ass {\blur4} right level,   is encoded SUP file into video directly with Hybrid result,    is what i want.

the below part is wrong,    is not right,    is encoded ASS file into video directly with Hybrid result,    is not what i want.



maybe your MPC player is not right, can you try Potplayer?

first, drag the original ASS to potplayer to see the correct effect, then edit the original ass file, {\blur4} change it to {\blur12}, save and drag it to potplayer, see the wrong effect.
