Hmm, first you talk about frames, then about blocks, is this correct? Diego

I do think so. A frame is made out of blocks, each of which can be of different types (here, that means that they will be painted differently). Does the text makes sense to you now? What would you suggest it ever you think that paragraph needs to be improved? BTW: I took the liberty to commit that patch as it was related to mencoder, and that it was good enough for me. I hope it's okay. Guillaume -- Live fast, die old, and make very sure everyone knows you were there. -- Alan Cox

BTW, the full text from x264 below. It's probably not worth expanding the already gigantic man page with a description that most likely only people hacking on x264 would benefit from / comprehend, and then they'd get the description from x264/common/visualize.c... /* * Some explanation of the symbols used: * Red/pink: intra block * Blue: inter block * Green: skip block * Yellow: B-block (not visualized properly yet) * * Motion vectors have black dot at their target (ie. at the MB center), * instead of arrowhead. The black dot is enclosed in filled diamond with radius * depending on reference frame number (one frame back = zero width, normal case). * * The intra blocks have generally lines drawn perpendicular * to the prediction direction, so for example, if there is a pink block * with horizontal line at the top of it, it is interpolated by assuming * luma to be vertically constant. * DC predicted blocks have both horizontal and vertical lines, * pink blocks with a diagonal line are predicted using the planar function. */
