Thank you for the feedback I will try to fix this problem
FYI, the virus scanner also went off with the following detection: Trojan:Script/Wacatac.B!ml
Hmm, Interesting, I don't know why that happened since it's just FFmpeg and a .bat file, this is probably a false virus detection but I'll investigate this, sorry.
No worries, It's definitely a false positive.
To anyone else reading this: the BAT just have FFmpeg render instructions. No malicious execution and etc.
