Im using After effects 6.5 to render a short clip & including text of white & red colour in PAL 768x576 Square pixels.

Problem I am having is when I 'make movie' to AVI (uncompressed) both white & red text is perfect - on compressing the AVI (using any programme (edius 2.0 / procoder etc) - the compressed AVI file : video footage is perfect and also white text perfect, red text or any other "colour" I use is really bad and jaggedy and colour blotchy - using same font for both white & red (all colours) - black and white fonts are the only that come out clear and crisp!!

Can anyone advise please ????
