1. Re: Correct settings for HDV capture
Harm Millaard Jun 6, 2011 10:52 PM (in response to Saad Khan)You can't use settings for cpature, since it is only a digital transfer of data. It is an exact copy of what is on tape, nothing more, nothing less.

3. Re: Correct settings for HDV capture
SFL46 Jun 7, 2011 3:04 PM (in response to Saad Khan)The HDV format was advanced by Sony and others to use the same miniDV tapes used for SD. In fact, your Canon XHAI can record and play either without changing the tape transport speed.
Your observation in relative file sizes is due to the fact that HDV is highly compressed (MPEG), whereas, SD (AVI) is not as highly compressed. This is one of the reasons folks (such as Harm) don't consider HDV to be an edit format, but just a delivery format.
Note that what Harm was saying is symantics--you capture an analog source through a capture card that digitizes it. When you transfer a image file from HDV or SD, it is already digitized, so a bit-to-bit transfer occurs.

Actually I use HDV quite a bit and it works nicely, being relatively easy on the system, the drawback is however the long GOP format. The same applies to XDCAM-EX. Ideally, one would have DV like material, without GOP structures, with around the same compression but with 1920x1080 or even 4K á la RED resolution with only 65 MB/s data rate for full HD 1920x1080 in 4:2:0 colorspace or 91 MB/s for XDCAM-EX material at HQ settings. Of course 4:2:2 settings require a bit more, as does RED 4K.To cut it short, I don't think HDV a delivery format, but an editable format.
