It's all going to depend on how the 24 mbps AVCHD stream LOOKS. Note
how much computational power is needed for good h.264 encoding when
the computer has the luxury of analyzing an existing set of data. Real
time capture with these temporal codecs is a minefield - even the best
HDV implementations
Just saw this, posted today about the new HG11 and HF11 Canon HDD
AVCHD cameras rivalling HV20 30 for quality.
Her thoughts:
Today the tape died, as far as I am concerned, with this fall of the
HV20/30.
