I d/l'd it and it's telling me the 30-day trial is expired.
Got this computer off ebay so don't know what the previous owner had.
Would rather not pop the $48 until I see with my own eyeballs if it
does a noticebly better job on mpeg2 files.
Also, would you say it's a valid comparison to take a .bmp capture on a
particular frame on mpegs made from the same source file by different
programs?
So far I've done captures from mpegs created by Pinnacle & Ulead DVD
studio 7 at what they're calling "DVD compatible" as well as the
highest bit rate mpeg2 each will do - 12000 kbps on Pinnacle and 14000
on Ulead. Comparing each to the same frame from the original DV source
file, they both show a very obvious degradation of the image. Wonderig
if I'm going to see anything better out of TMPGEnc.
I think you misunderstand the nature of modern
compression techniques, and the difference between
a still image and how your brain interrupts a series of
images displayed at a particular rate. A frame of
DV-25 will always look better as a still image, than
a single frame of a more compressed format, like
MPEG.
One of the most effective ways of compressing video
is to throw away the still image data that humans can't
perceive when those images are displayed as part of a
series of images. DV-25, being less lossy, retains more
of this useless still image data in its frames. This is a
good thing if you are asking a program to recreate a
still image from an individual frame of video, but is not
of any great value if you need a smaller more compressed
video file ( to say fit on a DVD ).
[Now PT will jump in here and rant about how that means
that his DV-25 provides a better source for his multi-pass
"re-transcoding" to MPEG. So you should first convert all
your video to DV-AVI. But he can never understand that
there is an even better source for MPEG encoding, that's
the direct output of an A/D chip. The A/D chip can be in a
camera connected to (or part of) the image sensor(s), or it
can be part of a DVD Recorder, or it can be in a capture
card/box connected to your PC. ] [With any luck that will
avoid a diversion of this thread. If someone can't resist, at
least change the subject line to start your own branch of this
thread.]
Since you are working with DV source material it is just a
matter of how to "best" encode that to DVD compliant
MPEG. You have indicated that you are looking for the
method that can provide the best image quality, and that
would mean you will likely need to trade speed and $$$ to
get what you are asking for. If you want very good and
very fast, you are going to need very many $$$.
( One other thing to remember is that the DVD standard
limits the overall bitrate and complexity of the MPEG data
used in a DVD. Being able to create MPEG at a higher
bitrate won't be of much use for making DVDs.)
You can get very good but relatively slow for a more
reasonable number of $$$. CCE Basic, TMPGEnc 2.5
Plus)
I don't know of a free encoder that actually does as well
as even the reasonably priced encoders, but they can come
very close.
As for installing a trial of one of the TMPGEnc Encoders;
you could try a different version. If the 2.5 Plus trial won't
install, try the 3.0 XPress trial or the 4.0 XPress. If you can
find a copy of the TMPGEnc DVD Source Creator, you
could try that as well.
If you wanted to avoid reformatting your existing hard drive,
you could add another drive as a "dual boot" and it wouldn't
have any of the history your E-Bay special has. When
operating from the either OS, you will be able to access the
files on your other drive, as well. Each OS keeps its own
registration history.
You could also Google and maybe find a way to remove
the installation history, short of totally reformatting your drive.
Luck;
Ken
