Are you editing at DV resolution? Titles will look a bit fuzzy after rendering although, with the right graphics, the quality can be pretty good. If possible edit at a higher quality setting, DVC50 or 8-bit uncompressed will look better and not be too taxing on your storage. It also depends on your typefaces and size. Serif or highly detailed typefaces will go soft pretty quickly. Obviously, tiny type will fall apart as well. If you’ve repositioned the type/graphic, it’s usually good to position it vertically on an even scan line, not a fractonal value. Sometimes just nudging it up/down a pixel can solve, or at least minimize the problem. Avoid scaling your graphics if possible. Compising them, more or less in place, will give you the best results. Also, highly saturated colors will fuzz out more than clean white or black characters. Gradients aren’t usually too much of a problem, but again, highly staurated colors, especially with text overlaying them, can have problems. Stick to a “good” format to save and import your graphics. I usually use .PSD, .PNG, .tiff,. or .pict with good results. Try to avoid j-pegs or bmp’s when possible, expecially ones using higher compressions. If you have PhotoShop CS, use one of the preset templates for DV video and avoid the conversion necessary to import into a video program.
Just a few thoughts…
