What _application_ or _program_ do you use to encode the raw YUV sequence?

I don't understand what you mean by "abvious", but the pink region/line
are _not_ block artefacts, because block artefacts are blocks, and pink
lines are not blocks.
Do you have a sample sequence (just a few encoded frames) which you could
put for download or send to me as e-mail? Not the full clip and not to the
list, please, because it's too large for that.
