Hi every one Am new here. I dont know if any one of you have work or program QTmovie before. I just want to find out How can i cut a video if i give it a starting time and ending time. Have not done this before and am new to this programming language. I've taken a look at the QTMovie Class but i don't know which one of the classes will benefit me and how will i use them. I can program in cocoa a little bit. i just need some one to point me to the right direction. thank you for your helps

Am using cocoa language to develop this app.

Have a look at the "Editing a Movie" section of QTMovie's documentation. These methods ...

– replaceSelectionWithSelectionFromMovie:
– appendSelectionFromMovie:
– insertSegmentOfMovie:timeRange:atTime:
– insertSegmentOfMovie:fromRange:scaledToRange:
– insertEmptySegmentAt:
– deleteSegment:
– scaleSegment:newDuration:
– addImage:forDuration:withAttributes:

... are pretty much all you need. If, for instance, you want to keep a segment somewhere in the middle of the movie and discard the rest, just delete the segments before and after that segment you're interested in.
