MillimeterMicrosoft Windows 7 Test Drive, Part 2

Synthetic Adobe Premiere Pro/Media Encoder tests
I tested the Adobe Creative Suite using both synthetic and real-world tests. The synthetic tests started with a 3:30 DV project with a range of effects, including chroma key, slow motion, and color correction, along with a superimposed logo and timecode. Outputting to the presets shown in Table 1, Windows 7 proved, on average, about 8 percent faster than Windows Vista.

Next, I tested with a range of HD source formats. The HDV-source video was a 1-minute multicam project with one base track and a half-sized picture-in-picture (PIP) floating from upper right to lower left with one 360-degree rotation. I output all HD formats to the H.264-Apple TV 720p preset. As you can see in Table 2, rendering with Windows 7 was 5 percent faster than that with Vista.
The AVCHD and DVCPRO HD-source projects were both 1-minute long with three clips on the timeline, a single base clip, a static half-sized PIP, and another half-sized PIP panning from upper right to lower left with one 360-degree rotation. Rendering times in the two operating systems were virtually identical for both formats.
The Red Digital Cinema Red One source project was a variation on the same theme, with one static background track and a spinning, panning PIP. I rendered a 34-second chunk of the project, and Windows 7 proved 11 percent faster.

Real-world Adobe Premiere Pro/Media Encoder tests
Next I rendered two real-world projects with the two operating systems. The first was the 53-minute second act of a ballet production shot with two HDV camcorders and edited using Premiere Pro's multicam feature. Effects included color and gamma correction, with about 2 minutes of rolling credits at the end of the video. I output this to widescreen MPEG-2, and Windows 7 proved 3 percent slower than Vista.

The second project was a 10-minute, single-camera widescreen DV concert shoot rendered to YouTube widescreen SD format. Here, Windows 7 proved 5 percent faster than Vista.
