Thanks Blast. I have two drives, but one of them is a USB2 external drive. It get about 30 MB/sec, maybe OK, but also 16% CPU power is taken up for managing the USB transfer. Should I get a second (SATA) drive instead?

Thanks, but what I am confused about, is why the two fields stored together belong to the same frame in a continious upper, lower…field stream. Couldn’t it happen that the last field from frame n and the first field from frame n+1 are stored as couples?

One last question Markus, if I may… When I capture clean progressive DV footage, it streams as interlaced, but doesn’t need to be de-interlaced in order to get progressive DV back I suppose. Does the NLE still throw away one field or does it detect the frame cadence in order to keep the fields belonging to the same frame, together? Or is the field order to be specified in this case.

Thanks again Markus.

Thanks Markus for the interesting information. You mentioned motion detection w.r.t. crossover artifacts, but does theis mean, in relation to my earlier question, that all NLE’s (not only DV Filmmaker)have motion detection for deciding which field belongs to which frame?

[Andre De clercq]

Still confused…Progressive DV images are indeed recorded and transported as interlaced fields. So APP behaves exactly the same way as with interlaced pictures. Field order may be not important but frame recognition IMHO is needed. If not, it can happen that consecutive field pairs comming from two different frames are being proceesed and if there is motion, all processed frames will show “mouseteeth”. So, my question is: does APP with progressive footage, recognise the fields which belong to the same frame?

Thanks Andre

GS400 like many other consumer (Panasonic)camcorders show way too much edge enhancement. This results in subjectively “sharp” images on small displays but looks awfull on large high-end screens. If this is what you mean by “too real”, you can try to apply low pass filtering, unfortunately at the expense of overall resolution loss.
