*** And thats the reason why this little prog "mp4cam2avi" can convert the
mp4s to avi's lossless without recompression - because its the same in the
core...

*** Of course they did. They included 2 Video editing progs from Ulead. (the
only prob for me: you can only produce DVDs/VCDs). You mabe don't know the
sanyo camcorders (C4, C5). They are not like all these "digicams with movie",
they are really 50/50 camcorder/stillcam. Have a look at the design and
you'll know what i mean...

*** Oh, oh...The C4 is absolutely compareable to a standard consumer
DV-tape-camcorder - stereosound in CD quality, Image stabilizer, 6x optical
zoom, recording time with a 2GB SD-card: 2 hours... i don't work for sanyo
but mabe you should really have a look at it... believe me: in some years we
will have less tape-camcorders on the market then flashcard camcorders.

bitrate...

*** yeah, it would save some additional space, but mp4 seems going to be a
standard format for flashcard camcorders... and in times of bigger and bigger
flashcards and since it's easy & lossless to convert...
By the way: sanyo told me that they'll bring a HDTV-flashcard-camcorder this
autumn...
