Dear ScanMan:
Thanks for your message.
SmartCutter is only able to cut on IDR ?
Definitely
not. The cut point can be any type of frame. Whatever it's I P B, the output movie will start and end preciously on the
picture you have defined. That is the basic need of frame accuracy.
Suppose you defined a B frame as a start point, then here is what will happen:
First, we restart the video stream from the B frame's I frame, aka its Gop, decode till that B frame, now we start encoding; the encoding will continue till the end of this Gop. So the work of start point is done.
Second, we copy directly the video stream between the Gop of start point and the Gop of end point, no decoding nor encoding happens at this stage.
Third, we do the same thing to the end point as what we do to the start point.
Did we make it clear? Perhaps you are confused by the water mark 'FAME'? The picutures with water mark on, are just those pictures re-encoded, as part of source gop.
As the nature of Gop in H.264/Mpeg2, there is no way to cut movies with only one single B or P frame re-encoded. All the frames following the cut point in its Gop will be re-encoded. If you are interested in these techincal details, we can have more discussion on this. That will be interesting and helpful.
Looks the Smart Cutter does not behave normally on your computer, our developers will keep on improving it, hope it will fit your demand soon. Thanks for your concern and all the time you have spent on it.
