Pixellation can be a problem. I do quite a number of screen-graphics sequences using nothing very exotic in the way of software; a 2005 ‘Ulead Photo-Impression 11’ and a scratch-built procedure of creating animations against a blue or green ‘chroma’ background. (I usewide-shots from high viewpoints to show routes covered on lower ground against a ‘live’ video background, instead of using maps’, where possible, then animate the results frame-by-frame. the basis for the process is an indentically sized still photogrpah, which serves as a temporary template for placement ofthe ‘indicator’, usually a ‘travelling’ white-line. (It works very well). One thing I learned early is to use a decent-sized graphics-raster for all stills, so although my stuff eventually goes onto 720 x 576 px, it begins with pixellations around margins as minimal as possible with a graphics well in excess of 1920 x 1080. A secondway to disguise pixels, is to set the margins of letters/objectslightly ‘off’ razor-sharp, to slightly fuzzy. It doesn’t cause degeneration of the outlines, much, and definitely hides pixels quite a bit.
Regarding title letters. Nothing is as effective in my video-editor (Magix Movie-Edit Pro 17 Plus), as the titles supplied with the software, which locate, by default in track-3. Text applied as part of the background graphic, and blue/green-screened into the final production, was never as sharp. The same has applied with other systems I have used.
