** ERROR: [ mpegènc ] Could not read YUV4MPEG2 to header:

Sera excrement... that? uhm... ** ERROR: [ ppmtoy4m ] maxval Expecting == 255, not 65535. Osea that the error this when creating flow YUV4MPEG2. Playing with ppmtoy4m I see that the problem has to do with the colors. The image that arrives to him at ppmtoy4m uses 16 bits of color instead of the 8 that the delay. We are going to analyze the code.
 
The place where the image is created that goes to him to ppmtoy4m (supposing that effect in the transition is not used) is: 
montage $memoryusage +label - shadow +frame - background 
white - geometry $geom "# " - # depth 8 ppm:$TEMPFILE

uhm... that rare... if depth 8 has the option -.... cagonto. To great the evils great remedies, despues to prove that convert works well, we added this line after the previous one (line 199): 
convert - depth 8 $TEMPFILE $TEMPFILE

So in case of kipiplugin we have to patch images2mpg.

Bye
