As i know by now.. the best codec to play around with HD material in Jitter is PhotoJpeg
(am i right?)
now iam searching a good and reliable converter....
i think most of you trying to help me will say "use quick time pro" it seems good, but it keeps crashing a lot on windows7
si if anybody knows about a little tool, that does what i want to do, he would save my digital life
thanks for your time
