I am exporting a ProRes 1920×1080 60i clip as a self contained movie. I then selected the 120 min. best quality preset in compressor to make my MPEG-2 and AC3 file for SD DVD. The quality is pretty bad. I get jagged edges and horizontal lines in the MPEG-2 file and all text is of poor quality.
Larry replies: Thanks for writing!
Try doing this compression in two steps, because the quality of the 120 minute setting is somewhat low. Compressionists call this “Pre-Compression,” which means to prep the file into its final format before compressing it. When you need to create multiple compressed versions of the same file, pre-processing can save a lot of time.
1. Resize your HD movie to SD using Compressor but don’t compress it.
* Encode it to ProRes HQ
* In the Frame Controls tab, turn Frame Controls On, set Output Fields to Progressive, Deinterlacing to Better, and turn Adaptive Details Off.
* In the Geometry tab set image size to 853 x 480 using a custom 16:9 aspect ratio
2. See how your movie looks. It WON’T look as good as HD, as the image resolution is seven times smaller. But it should look OK. The best approach is to work with only a short – say 20 second section – to save time until you get the settings you want.
3. Then, compress the resized image to MPEG using the DVD Best Quality 120 minutes setting.
This two-step process takes a bit longer, but should provide a lot higher quality.
