Figure 2. Resizing the source video to fit in the smaller project.

Once you create your preset and start to edit, note that you’ll have to scale the video to a lower resolution to make it fit in the smaller window. You can see this in Figure 2, where I scaled the original DV video to 75 percent of the original size. Or you can leave the video at 100 percent and reframe the video within the window—say, if you hosed rule-of-thirds positioning or you want to convert a medium shot into a closeup. As long as you don’t zoom higher than 100 percent, the video will be perfectly clear.
Figure 3. What a difference a change in preset makes.

Long story short, after creating the second project and getting my video situated, I re-rendered the file. I found the results much improved, as shown in Figure 3. This is most obvious in the picture frame, which shows much less aliasing. Although it's more subtle, if you click to see the original image at full resolution, you’ll notice additional detail in the chart—particularly in the horizontal patterns on the corners of the colored grid.

Why would the preset make a difference? I have no idea, and tight editorial deadlines and a looming vacation make it highly likely that I won’t find out before you read this article. Still, it tends to add credence to my suggestion that streaming producers working in Premiere Pro use a preset that matches their target output. Note that I went back and tested Final Cut Pro with a 640x480 preset, and I produced a file identical to the original file—which I produced using a DV preset.
