    I'm looking to buy a CanonHV20, I was looking at a dv tape distributor online and I couldn't HDV tapes. Are they the same? I appreciate the help, I'm still learning about they advanced stuff. If anyone knows where I could find a used Canon HV20 that would a big help too. Thanks

    pick any decent miniDV tape. something you will be able to easily find. you don't need hdv tape. it's more important to stick to one brand/model tape to help keep the heads clean.

    So you can record in hd to a regular mini-dv?

    edDV- Thanks for the link, that helped allot.

    zoobie- I would like for you to elaborate what your referring to as "you're a sitting duck waiting to be ripped off". How could I be ripped off? I'm thinking your talking about dv tapes. Hv30 Looks cooler but not much changed, not to mention that it will be $1000+. Do you know the release date? I see online I can get a hv20 for around $650. Should be an ok entry level cam. Do you have a better recommendation?

    The HV30 is going to be expensive for a while. Check and see if it has features you can't live without.

    There' s a dedicated support site for the HV20 - Http://www.hv20.com . It's hard to go wrong for $650

    Save up some $ and add a Steadicam Merlin for beautifully steady video during filming

    or the much less expensive (but not as groovy) modo steady

  9. The bit rate for HDV and DV are the same.

    The tape couldn't give a rat's ass whether the 1s and 0s come from HDV or DV.

    As long as you buy high grade miniDV tapes, you're set.

    People claim stuff about more drop out problems. As long as you have quality tape, no issue.

    just saying to totally research your plan...know what you're getting, how it works, handle the cam(s) in question, and basically do your homework
    why?
    too many salesmen make their living off consumer ignorance
    how would I know?
    I used to sell...top salesman...usually of huge messes

    I think there's a post here where you can also make your own steadycam but for me, nothing beats a tripod

    I'll go with the canon hv20 for indoor shots and the sony HC7 for outdoor...but I'm biased toward sony because I know it's a great little cam

    Can anyone post a link to something that gives information on the difference between 24p and 30p? The Hv30 can use both, from what I know its frame rate. But which is better for which application? Thanks

    24p is the traditional film rate and is used when video is substituted for film in the post process. 24p (23.976p actually) is directly supported as a DVD format (see https://www.videohelp.com/dvd ). 24p also has a direct path for release in both PAL and NTSC formats although this gets complex and is an advanced topic. Downside is film style camera technique needs to be used since motion update is only 40% of normal 59.94 field rate. 24p needs stable camera support (tripod or steadycam) and controlled pans and zooms to avoid looking jerky.
    Process flows are described in these links.
    http://en.wikipedia.org/wiki/24p
    http://www.videomaker.com/article/9341/
    http://www.digitalvideoediting.com/Htm/Articles/chazz24p_editorial.htm
    http://www.adamwilt.com/24p/
    http://24p.com/reference.htm

    30p (29.97p) is similar to standard 480i/1080i interlace video except that both fields reference the same sample in time. Normal 480i/1080i interlace video scans alternate fields every 59.94fps giving an effective 1/59.94 motion sample rate where 29.97p samples both fields every 1/29.97 sec from the same frame. 30p is easier to integrate into normal video editing than 24p but suffers from half motion update. 30p is useful for heavy compression or web distribution. It is also used for special effects processes that require progressive video.

    If you have zero drop outs, no issue.

    When you have a single drop out, it can be invisible with DV because of the redundency in still frames and error correction. Single drop outs are always visible (half a second freeze!) with HDV. Hence the concern.

    Multiple drop outs are a pain in either format, but you need damaged tapes or decks for that.

    Cheers,
    David.

    So how do you avoid drop-outs?

    Dropouts are gaps in the tape formulation that can be manufacturing errors or due to tape path wear, surface dirt or head dirt. Tape quality has improved in general especially for DVC "pro" formulations used by producers and broadcasters.

    Dropouts used to be a major problem in the Hi8 days unless masked by external hardware dropout compensators. The DV format and camcorder chipsets added advanced hardware dropout compensation that effectively masked the problem until extremes of head dirt.

    Dropouts usually affect one to a few pixels not entire frames. The long GOP nature of HDV MPeg2 makes possible wiping out multiple frames with loss of one I frame but decoders/players correct or compensate for this and it hasn't been a major issue in all the other tape based MPeg formats like IMX or for HDV so long as adequate tape is used and tape paths are cleaned periodically.

    Very true. Hence, the HDV format employs much more Solomon-Reed cyclic redundancy than DV which makes it (necessarily) more robust as far as drop outs are concerned.
