No, I mean I had rendered the avi file with the slow motion and it had looked good. The "before" is a reference to the screenshot which is from a rendered final avi video file. I burned that video file to a dvd.
The screenshot labeled "resample disabled" shows how it originally looked, without any interpolation. When I rendered the video together, the slow motion clip turned out to look like the "before" screen. Watching the dvd, I was happy with how that looked. About a year later, the same rendering process made the final edited avi file look like the "after" screen. Watching slow motion clips rendered since then has looked a lot worse.
