What is the target display device. If it’s for desktop viewing, square pixels are fine. Otherwise, the project should should be formatted with a full screen or widescreen aspect ratio, and the images should be resampled to match.
If there is no video in the project, it’s probably safe to say that the project should be Progressive (not interlaced).
Check the project settings, or create a new project. Look under Project Settings/General/Video/Fields – choose No Fields (Progressive Scan).
I think Cinepak is the default compressor, when you switch to desktop editing. For your video rendering settings I’d recommend using Compressor: None.
As far as render times, make sure your output matches your project settings. If you are expoting to a non-square pixel format you’re invoking an additional rendering process that increases the render time.
Also, if your output is set to Fields and not Progressive, that might be causing the poor quality.
Further, if this program will be displayed on a CRT, you should resample your images using some type of “deflickering” technique, such as Deflickerator, probably available here…

Are you exporting a “movie”, or using Adobe Media Encoder, or something else? What codec (compressor/decompressor) are you exporting to, If it’s MPEG it will take a good deal of time.
just some ideas
