I'm looking for a mass edit videos tool

I'm using porn reupload method so I need tools can
cut multiple videos, remove watermarks, combine intro at once.
I'm using avidemux for cutting, easy video logo remover to remove watermark and ultra video video joiner to combine intro but I can only edit one video.
anyone know?

Thanks

do you have permission to remove the watermarks?

For cutting, i use ffmpeg in a bat shell.

For watermarks, Video Watermarker Pro works fine.

I want to join an intro and the movie with batch but I cannot do it with ffmpeg as files have different format, definitions.

I am looking also for a mass joiner (with reencoding) one intro encoding to many videos.
