Quality of saved mpeg file

Post by Jaap »

When i play a project in uLead itselve video quality is much better then when i am saving as a MPEG for example. How can i improve the quality.
Images and text are getting "fuzzy" .
I selected 740 x 480 and saved as MPEG 2.

All (NTSC) DVDs are 740x480 MPEG-2*. Your DVD can look almost as good as a commercial DVD if you start-out with a high-quality video. (The professionals do have better MPEG encoders.)

A higher bitrate may help somewhat. But, the bitrate mostly affects the quality during motion.

On a commercial DVD, the opening credits are usually large fonts, and they are clearly legible. The ending-credits are usually small fonts (in motion) and are usually fuzzy.

Where did the original video files come from, and what format are they? Does the text appear in the original video, or did you create it with Video Studio?

You will always get some quality loss from the MPEG-2 encoding. The end result will be best when you start-out with a very high quality source video.

Titles generated with Video Studio should appear sharper than text imported with the original video. This is because Video Studio can align and position the text-pixels precisely. If the text already exists in the video, it's just a "best-fit" into the available pixels.

When you use still images, the original image will have "square pixels". (i.e. a 740x480 still image does not have the correct proportions for 3x4 or 16x9 video.) There will be some quality loss when the image is re-rendered to video with non-square pixels.


* The DVD spec allows a couple of lower-resolution options as well as MPEG-1. But, I've never seen a commercial DVD that uses any of these.
