Although Adobe Premiere Pro CS4 will be the fourth incarnation of Adobe's professional video editing software, it's only the second version compatible with the Mac OS. Its debut on the Mac was a laudable, though for many, overdue. By now, Premiere Pro has had time to shed associations with its last Mac-compatible predecessor, Premiere 5.1, and establish a fresh reputation with Mac users. The latest version includes features that should further strengthen its credibility on the Mac platform.

Here's what to expect from Premiere Pro CS4 when it ships next month, both as a US$799 standalone product and as a part of the $1,699 Production Premium suite along with the latest versions of After Effects and Soundbooth.

More tools for Mac users

A few of the most notable new features aren't part of Premiere Pro CS4 itself, but come in the form of companion programs. With CS4, Adobe eliminates the most conspicuous disparity between the Windows and Mac versions of the Creative Suite by including a Mac-compatible version of Adobe OnLocation. OnLocation CS4 lets you use a laptop to monitor, capture, and log video in the field. Prior to CS4, Mac users could only run the program via Boot Camp. Premiere Pro CS4 also ships with Adobe Media Encoder CS4, a separate but integrated program that can batch encode any combination of Premiere Pro sequences and other files to multiple formats. In the past, you could export just one sequence to a single format at a time.

Of course, Premiere Pro CS4 also boasts numerous new features of its own. A new Media Browser panel lets you preview and import footage on your computer from within the Premiere Pro interface--which is particularly useful when importing material from tapeless media. Premiere Pro CS4 expands its support of tapeless media to include P2, AVCHD, XDCAM EX, and XDCAM HD. And Premiere Pro CS4 not only supports the media, but its metadata, as well. This way, shot information encoded in the field is present in Premiere Pro, making it easy organize and search the footage without intermediate steps.

Search speech

In fact, more extensive support for metadata is a prominent feature in Premiere Pro. A new Metadata panel lets you view and input information about a clip or even its source file. But perhaps the most exciting implementation of metadata is Premiere Pro CS4's speech transcription feature. It analyzes a clip's audio and creates a text transcript that's timecode-specific and searchable by keyword. Needless to say, it promises to be a real boon, especially to editors who have many hours of documentary footage.
