Challenge with scan converted computer footage
Not sure if this is more appropriate for the Encore forum, but I’ll start here. I recently created a short video for a client that incorporated a computer screen showing the client’s software in action. The screen displays lots of small text, columns of numbers and some waveforms. I captured the output of the computer via it’s DVI output using an Image Pro scan converter. Capture was at 1920x1080p. I created the video in 1920x1080p using After Effects CS5 and Premiere CS5. I then created a Blu-ray and a DVD using Encore CS5. On the Blu-ray, I think the computer screen looks great. My issue is with the DVD. I outputted an MPEG2 DVD file, first at CBR8 and then CBR 9. On DVD, the computer screen suffers considerably. Much softer and hard to read the on-screen text. I realize I’m downscaling quite a bit, but I’m wondering if there’s any way I can get a better image? The piece runs just 3 min 45 sec, so I have lots of room on the DVD. Any and all suggestions would be appreciated. Thanks in advance.

Not only are you downscaling resolution, you are going from progressive to interlaced. As long as you want it compatible with DVD players, there’s a limit to how much you can do.
One thing I would look at is re-capturing the footage for the DVD version with the computer set to a lower resolution; even as low as 640×480. Depending on the software, that may be an issue as well. It would also require a re-edit for the DVD version. But with reduced downscaling from the original, you may get a better result for DVD.
You’ll still have to endure the difference between progressive and interlaced, though.
