i just want to report a bug that caused major problems in my last
production.
we made a seamless looping and tiling water-caustic video and
wanted to use multiple projectors side by side to show that video
and a webcam to steer some transitions of colors interactively.
so in quartz composer we have set up everything so that all worked
well. then our customer said that the videos on the projector do
have seams.
we checked our original unprocessed (and uncompressed)videos, we
checked the quicktime compressed video that where used to feed
quartz composer, we saw no seam at all.
after some huge wondering we made a screenshot of the qc-viewer
window and bang here the seam was visible. since we croped all
videos correctly in qc i made a testpicture with the original
resolution and set every pixel from the border inwards another
color to see how many pixel were missing in the output.
