Draw 35mm Film Template in Illustrator

I'm looking for someone to draw a 35mm film template (see attached image) in Illustrator.

I'll be using this in a mobile app and will put an image behind it.

Requirements:
- The perforations are all the same (so can be copy-pasted)
- The perforations must be transparent (in example they are white)
- Note that a perforation does not seem to be a smooth/simple rounded rectangle (corner radius seems slightly larger)
- The center area must also be transparent
- The non-transparent part must be black
- The corners of the center area must get a small corner radius
- The center area must get a narrow gradient from black to fully transparent (to get slightly soft edges when I put an image behind). In sample image dimensions: width of 3 or 4 pixels only; so present, but hardly noticeable.
- Optional: Make the center area edges slightly rough/uneven (to mimic the sides of a real film negative).

I want the Illustrator file, a PDF, and a high-res (3x the size of the example image) PNG.
