The conditional execution filter for virtual dub was a curiosity for me until recently. I thought "who would need it?" but, now I do!
However, a problem. When evaluating an image to decide which filter to apply, for example using "luma", the evaluation is based on the whole image. What I really need is for it to evaluate only a portion of the image.
Say for example, I have really bad sync, or a film converted to video with random bad frame alignment... I look for the black frame band in the picture (x1,y1,x2,y2), and then shift the picture back to where it should be. Hence correcting random occurances, a *very* *extremely* time consuming task to do manually for each frame in an hours' worth of material!!! :(
Is there a 'plugin' for "conditional execution" that does this? I had a look at the "rgb" example 'plugin', but I am not a programmer, and I have no compiler...
Thanks people :)
