avoiding artifacts
hey
is it in anyway possible to avoid compression artifacts when compressing text on a black background?

Use a high enough bitrate, proper keyframing, a proper source, etc...

right, but
it doesnt matter what data rate i put in
looks great in huffyuv but as soon as its compressed with a lossy
codec there's a lot of greyish flickering pixels around the text

Is you source a solid black image with solid-colored text on it, or are you recompressing from a previously-compressed black video image containing text? IF you're doing the latter, then odds are that the artifacting is already in the source, so you won't be able to recompress it without artifacting unless you use one or two specialized plug-ins for VirtualDub or such.

Files on PSX discs are compressed. Encoding it into Huffyuv simply prevents it from losing any further data; however, you are still reencoding from a lossy source, and thus you will need to take additional measures to prevent further artifacting.
