Quantitative tools for the Mac?
Hi all,
I have been tasked with an interesting project. I need to see if there are any tools that are available to objectively analyze the quality of a compressed video or image. Really, I need a tool to measure the image quality of a real-time streaming video, but I would be happy to just be able to analyze the quality of a screen grab.
I need to be able to say that one product has x% less quality than another product.
Any thoughts, pointers… huuuulp?
Thanks

Sadly, as far as I know, and I’ve looked hard, there is nothing on the Mac. (or for PCs for under £10k)
The only useful tools are graphics apps like Photoshop, GraphicConverter, COREL etc, that allow batch files to produce graphical differencing. Leaving the rest to maths and the human eye.

There is something sort of for MPEG2 on the Mac if this is what you’re thinking of.

Not on the Mac, but my company inlet technologies (inlethd.com) has a tool for analyzing video files named Semaphore. Its only $995 – cheap when you compare it to the $10k+ competitors. FWIW, it runs great in boot camp and several of us use it this way.

There is a fully functioning 15 day free trial available, so if you just need this as a one off test, you may not have to by it at all.
