    Hello,

    Does anyone know what the sensitivity of the HVX is? And is that sensitivity for DV, HD progressive or interlaced or are they all the same? I am trying to get a fix on what the exposure factor will be going from a 60i SD camera with a F/11 @ 2000 Lux standard sensitivity to the HVX shooting 720 30p.

    Also, can you transfer footage directly from a P2 Store to a stand alone hard drive?

    Thanks,

    Drew Harty

    Depends on who you ask.

    I’ve heard the equivalent of 320 ASA being thrown around by a couple people, but that’s just a number. In my tests, it has performed 1 1/2 – 2 stops slower than my DVX100A. Best thing to do is test it yourself in a controlled environment and see if it meets your needs. Good luck to you.

    One reason why the HVX200 is not as sensitive, is because of the nature of Progressive ccd’s vs. interlaced ccds. I’ve read articles (like this one) https://www.showreel.org/memberarea/article.php?172 that suggest an ISO of 320, but I’ve also read alot of people talk about how the HVX needs a lot more light. One thing is for sure, if you do need to boost your gain in post, it will still look better to downrez a hd signal that has been boosted rather than use SD.
