Unless I'm mistaken, Premiere Pro isn't available for a Mac, so either you've done something fairly weird or you're in the wrong forum...

If just working on an image reduces its quality, you may be dealing with a proxy. Try rendering.

It's your computer, you can do whatever you want; but changing the frame rate alone will probably result in something that looks like 29.97 hacked to look like 24. If what you're looking for is the popular 24p look, try a real 24p camera. Most everything else falls short.

This is called the Mac Video Forum because it is where we discuss issues related to video on Apple Macintosh computers. A Mac is a unique computer that doesn't use Windows and hasn't used Adobe Premiere since version 5 or 6. We edit mostly on Final Cut or iMovie.

You are certainly welcome to ask questions or comment, but it's kind of like taking your Ford sedan to a Volkswagon shop - we have different problems and do things differently.

A proxy is a person or thing that represents someone or something else. If your lawyer goes to court to argue your case, he's your proxy - he speaks for you. In video, a proxy is (usually) a lower quality image that is used instead of the source because it can be handled more easily. It's not unusual for a proxy image to lose quality when it is altered. The quality is usually restored when the sequence of video is rendered. What really happens is that a new proxy is created.

I have no idea when or where proxies are used in Premiere Pro, but many editing systems use proxies to speed things up. In virtually all cases, there is a "rendering" operation which restores the quality from the source. I can't tell you how or when to do this (since I don't have a computer or software like yours) but it's a good bet that if you render, the image quality will improve until you alter it again.

Good luck.
