    Sorry for so beginner question.
    Can Hi Def video be transferred and authored to regular 4.7 DVD disk or it
    has to be done on blue ray?

    Hi Def content can be authored on standard (red laser) 4.7 GB DVDs using
    either AVCHD, BD5, or HD DVD formats. Depending on the specific codec
    employed (mpeg2 or h.264/AVC) the recording time for a disk is nominally
    around 23 minutes for 25 Mbit/sec HDV high def content video, or as high as
    around 32 minutes for a slower 16 Mbit/sec AVCHD high def program. Other
    than the shorter play time, the video quality is identical to what is
    achieved with BluRay.

    A dual layer 9.4 GB DVD, also recorded with a conventional red laser burner,
    can essentially double the recording times cited above.

    Will regular DVD player deliver hi def to HDTV?

    Nope, SD (standard definition) only.
    Regular DVDs can hold a limited amount of HD material which will work on
    a PS 3.
    Not sure about other HD players.

  5. Technically, this is correct - but if either the TV or DVD player
    can upsample well, and if the player has RGB or HDMI output,
    the SD picture from a disk can be very good (so good that I
    find no need to replace standard DVDs with Blu-ray versions,
    or to avoid buying standard SD DVDs instead of Blu-ray versions).
    Side-by-side comparisons between the SD and HD versions of
    the same movie showed me that the HD version does have a bit
    more real detail, especially during motion, and smoother motion,
    but not enough to pay nearly $30/disk vs. under $5 for pre-viewed
    SD DVD copies, for me... (but there are some $10/disk Blu-ray
    disk bargains around, and I do buy these).
    And most other Blu-ray players...

    "Most" being the key word here.
    Anyone who wants to try this should bring a test DVD to their local
    big box electronics store and try it on a variety of Blu-Ray players
    as not all of them will work.

  7. Yes, of course...;-)

    So in this case when you have HD material on 4.7DVD disk, computer is the
    only device you can watch HD footage?
    I don't think you can stick 4.7GB into blueray player, do you?

    That's what I was saying you can do so the answer is yes.
    Folks on the Vegas forums are doing this all the time if they don't want
    to spend the money on Blu-Ray blanks.

    Mike Kujbida, Apr 28, 2009
  10. You also save money by not needing a Blu-ray writer to write
    HD disks (but a Blu-ray player is necessary to play the disks).
    I take my edited HDV files and convert them to AVCHD in
    Vegas at the maximum available data rate of 16 Mbps (Vegas
    doesn't specify whether CBR or VBR, but since I can get about
    45 minutes on a single-sided DVD, it is likely VBR) and author
    the resulting files to red laser disks. The results are excellent,
    but the file conversions can take a considerable amount of time.
    Once the price of Blu-ray blanks drops far below what it is now
    (and much closer to the price of DVD blanks), I will switch to
    using those - but not yet...
