Hello everyone!
I started the previous thread with genuine intention to compare the two cameras by their expected pros and cons and although I gave it a bit provoking headline I believe I stayed on-topic with no under-the-belt hits.
I have to say I like this forum a lot and I respect it and I also love Panasonic DVX100a - it's my favorite SD camera but I see no point I evangelising the HVX instead of comparing it with its competition. I was very suprised where it's gone over the night - it was funny but way off-topic and resulted in closing the thread. And being a troll from Europe I was asleep and I couldn't react.
So let me please continue on comparing their respective advantages. Thank you Barry Green and Ryan W for your remarks. It is of course true that for a relevant and most important comparison we will have to wait to see their actual footage. But these cameras are so hot and anticipated that it's just hard to sit still
So, the main issues again:
LENS
With removable lens and the adaptor for 1/2'' lens the advantage seems to be on JVC's side. However its set lens seems to be lacking on the wide-angle side. Can anyone tell me the 35mm equivalent on its 13x and 16x zoom lens? And important: is there no autofocus and optical image stabilisation? If not, that might be a serious adventage for HVX.
RECORDING CODEC
Clearly, 100mbit 4:2:2 DVCproHD must be superior to 19mbit 4:2:0 MPEG2.
However, I believe JVC's 19mbit for 720p might produce less artifacts than 25mbit for Sony's 1080i. It's not so long GOP either - in 720p there is I frame every 6 frames compared to Sony's every 15 frames. With simultanious HD recording it should be dropout safe.
SENSOR
I believe it's a big advantage to have a native sensor - as any stretching [by pixel-shifting or otherwise] of undersampled sensor resolution may lead to horizontal aliasing. Barry Green pointed out that too dense pixel resolution on the sensor hinders low light performance, dynamic range and adds noise. That probably means that neither HVX nor HD100 will outperform DVX or XL2 as far as dynamic range and low light perfomance is concerned. We will have to wait for the footage to reveal who found better compromise.
