question for those with HV20 and blu-ray
Hi all,
I have been wondering - Blu-ray players provide 1080p footage as I understand it. The HV20 sends 1080i however. For blu-ray, the display needs to be set as progressive scan, but for the HV20 it needs to be interlaced. If one connects the HV20 to a display THROUGH a blu-ray player, does the player upgrade 1080i to 1080p so the user need not switch the display back and forth according to the source? (I am sure 1080i to 1080p wouldn't look so good though, but still I thought I would ask). Also, if I connected a blu-ray burner to my PC, and Sony Vegas Movie Studio Platium is upgraded to support it, would the end product be burnt as 1920x1080i or 1440x1080i (given that it has been captured as HDV standard) ?

I don't own a Bluray player. But I think Bluray player will have different modes to accomodate the source. If the source is 1080i, it should playback 1080i without problem.
For HV20, you can shoot in 24P then remove the pulldown with tools like Cineform or the free HV20pulldown.exe. After the process, the footage becomes 1080p. |

The HV-20 outputs high-def only through the HDMI and component outputs. I'm unaware of any BluRay player that will accept either of these and pass them through to a television.
Presently available BluRay players will not play a BluRay DVD-R or DVD-RE, i.e. one you burn on a computer using a BluRay burner. They will, however, read high-def mpeg2 files stored as data on a standard data DVD or, I think, a data BluRay disk. The fact that the video is 1080i doesn't matter -- BluRay disks can read it and will send the appropriate video format to your television, either 1080p if you want the player to upscale, or 1080i if your TV will accept it. |

I have to admit, I am not aware of any blu-ray players that will accept input from an external source and pass it through for display. Then again, I am not currently in the market for one so I have to admit that I do not know if there actually is or not. I would imagine it is only a matter of time given that blu-ray recorders with inbuilt hidef tuner and HDD do exist (but up for sale I do not know).
With respect to editing software, I was wondering when (and if) something like Vegas supports the "make Blu-ray" tab as well as the "make DVD" tab, the 1440x1080i footage would be likely to be converted back to and burnt as 1920x1080i on the blu-ray disc. I am sure there would be some sort of resolution standard for discs burnt on blu-ray that are intended for video rather than data use. Tim |

But don't despair, 1080i works fine for movies. There is no difference between 1080i and 1080p if you watch 24p movie telecined into 60i and the TV is capable of decoding 3:2 cadence. Oh, by the way, the HV20 outputs 24p exactly in the same manner as used by networks for broadcasting movies, by employing 3:2 cadence. |

Umm, nobody told me that. Going by my non-HDMI TV, if I try to display progressive I get nothing - it can't support it. I does however support interlaced and the HV20 works well with it. So, I am sure you can see how I drew my conclusion not having HDMI equipment. It's good to know about the handshake however - that fills me in on a few things.
Yep, I'll just go out and spend $700. Damn, while I am at it, I'll spend $3000 on a "full HD" TV. It's only money right !! Michael, you lost me in the last bit of your post. I'll just nod my head and say "ah-huh" given that my technical knowledge is not quite on par. I live in PAL land - how would I know if my TV can "see" recorded 25fps progressive embedded in the 50i stream and thus display 25fps progressive? (i.e. see the 2:2 pulldown if I understand things correctly). Tim |

I guess you should just look at the specs, if they do not mention something like "movie mode", then read reviews or get a test DVD and test yourself. I tested my TV with a test DVD and found that it works with 3:2 cadence, but does not distinguish 2:2 cadence. There are some shows like Friends that are shot in 30PsF, but my TV does not get this, it just works in native 60i mode. |
