Done. I put the newlines in so it would look better but being able to copy and paste is better

I figured that was the reason, but it sadly breaks the copy+paste mechanism. Perhaps it's even easier for users to simply do a "select all"+copy on a form field looking like this?:
-y=
-i=$inputPath
-i=$projectPath/logo.png
-filter_complex=overlay=(W-w)/2:(H-h)/2, unsharp=3:3:1.0:3:3:0.0, scale=min(iw\,trunc(iw*min($videoWidth/iw\,$videoHeight/ih)*0.5)*2):min(ih\,trunc(ih*min($videoWidth/iw\,$videoHeight/ih)*0.5)*2)
