Two Halloween effects on MixVio: AI Zombie and Zombie Love Story

Hi makers, Alex from MixVio here with a seasonal update.

We have two Halloween effects live:

AI Zombie: upload one photo, get a 5-second zombie transformation with sound. Cracked skin, blood streaks, hollow eyes, a final scream. 720p, 21 credits.

Zombie Love Story: two photos, one person stays human and one turns. 15 seconds in three beats: a standoff (a handgun is aimed and dropped), a lunge, then a twist cut to a hug. Not gory. 9:16 or 16:9, from 45 credits.

What we learned building them: the thumbnail matters as much as the clip. Both effects have sensitive moments, so we pick the first untouched frame or the final hug as covers.

Question: which do you think travels further in a group chat, the 5-second scare or the 15-second story?
