<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Ive created a patch and framework that allow one to dynamically route pix data to various pix objects. I havent used it extensively, but it essentially goes like:<DIV><BR class="khtml-block-placeholder"></DIV><DIV>[gemhead]</DIV><DIV>|</DIV><DIV>[pix_film]</DIV><DIV>|</DIV><DIV>[send13 movie1]</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>... some effect module:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>[someOtherPixSource(</DIV><DIV>| [movie 1(</DIV><DIV>|/</DIV><DIV>[recieve13]</DIV><DIV>|</DIV><DIV>[separator]</DIV><DIV>|</DIV><DIV>[pix_effect_here]</DIV><DIV>|</DIV><DIV>[send13 effectOut1]</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV> etc etc.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>the send receives can be dynamically set via a pulldown menu, or whatnot. also, be sure to quickly toggle rendering on and off to make sure you dont get hiccups (at least with older gem versions)</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>You can get trickier by removing the separators if you make sure to always reset the rendering [stop,start( to gemwin, but it requires more logic in the patch. The above method isnt all that efficient, but does allow for dynamic routing of effects. You could event script it to spawn new effect modules for arbitrary length effect chains, but there arent really enough pix_ effects to make that worthwhile I dont think. Also, beware of colorspace issues that some of the pix_effects have. I try to stick to YUV, since it is fastest.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>peace.
