Panasonic DVD recorder re-encoding... definitive answer soug |
|
|
If I record a program in a mode (eg. XP) and then burn a DVD in the
same mode (eg. XP) does the recorder re-encode the material or does it
write it without alteration? I hope this question makes sense.
The model I have is the DMR-E85H.

the definitive answer is on page 35 of the manual.
the summary: if you have 'dvd-r high speed recording' set to 'on' [page 41] AND
the source material meets the requirements on page 35, then no re-encoding will
be done.
you will know as follows: if the machine allows 'high speed dub' when you go to
dub, then you have met the requirements -- if it does not, then you will be
re-encoding during dub.
[note: all of the above applies to the NTSC USA model (at least) and page
numbers refer to the USA English manual (downloadable from amazon.com) -- your
mileage may vary.] |

I think you'll find it's not.

This is not stated as an exclusive condition.

|
I'm recording in variable rate mode, rather than fixed (HS dub).

Mine is a UK model, but I doubt it would differ.
Say I record a 1 hour program in XP mode and dub to disk in XP mode...
is the material re-encoded.. that is the question. |

It's not the best of translations.

You have answered your own question. High-speed dub == no re-encoding. Normal
speed dub == re-encoding. The terms are interchangable for panny. Note the
table: high speed == original picture quality, normal speed == [quality] can
change. Hybrid VBR recordings cannot be high speed dubbed, therefore they will
be re-encoded. That's why the 'dvd-r high speed recording' [i.e., no re-encode
dub] switch turns off hybrid vbr.

Question about audio when re-encoding on Panasonic DVD+HD re |
|
|
I am recording a weekly radio show in XP mode for the best audio
quality LPCM. I have noticed when re-encoding these recordings using
FR mode the audio mode stays in LPCM. What I'm wondering is whether
the audio is likewise unaffected if I compress the recording down to
the longest play mode available. The reason I ask is because I'm not
at all interested in the picture quality and this would save a great
deal of space. A further question - if I store these compressed
recordings on DVD-RAM and bring them back to the recorder, will it be
a bitwise copy? Any help gratefully received...
The model is DMR-E85H. |

You could remove the video completely on a PC.

I've a different model of Panasonic and can't comment on the audio
question but as far as copying is concerned the High Speed copy is a
bitwise copy. This is the only mode for copying from the DVD-RAM back
to the HDD.
|
So is it true to say that bouncing material from HD to RAM and back is
bit perfect? |

That is my intention. However to get it to the PC I need to burn to
DVD-R and I don't want to waste them. There's several hours worth of
material in total. |

Can't you use DVDRW or DVDRAM?
Or if you have a DD input on your sound card you could capture the
audio directly.

Nope.
No reader on PC.

Too far.
So back to the original question, when re-encoding video on the are
the audio tracks affected? I may write to Panasonic for an answer. |

Buy an IDE DVD burner that can handle DVDRAM and replace your existing
burner with it. This will cost all of £30. End of problem.
