Capturing my old vhs-c tapes onto my pc. My video only has
composite via scart, and the quality
is rubbish. What new vcr's (there are not many available) have
s-video out? Reading the spec's on
these tells me nothing.


The old adage is true, crap in = crap out!

Your recordings are in composite and will still be of composite
quality if you converted them SVHS (or indeed feed them through
a Digibeta broadcast deck and out via SDI), I suspect that your real
problem is in your computer capture method - what are you using to
capture, please don't say a USB device...




nope, ATI x1800xt 512mb VIVO ;)
more than capable of capturing vhs.

No you will not. You will be editing the MPEG-2 bitstream directly
without any re-encoding.

TMPGenc (which _you_ mentioned) includes a clunky MPEG-2 editor
that
cuts on I-frames without any re-encoding. It's really crappy
software,
but it does work and is lossless.


Well if all one wants to do is 'crash edit' then that can be done
with the pause button on the DVD recorder whilst recording!

If you want to ad a wipe, fade or title you will need to re render,
that is lousy in the MEPG format.

Depends on your software, you might only be re-rendering a single GOP,
and it's not that lousy, depending on exactly what you're doing and how
often you're doing it (you have to re-render the affected frames in DV
too). It's a compromise, all video compression is.

Rememeber the signal path you are advocating is
Light-RGB-YCrCb-YC-(massive compression)YC on VHS-YC-DV-MPEG
(DVD)
And the other option is
Light-RGB-YCrCb-YC-(massive compression)YC on VHS-YC-MPEG-MPEG
(DVD)

There's bugger all in it. If the source was already in DV, then
obvously capture DV. If the source is a DVD, capture MPEG. If your
source is something else, you're probably better looking at the target
format (archive on DVD/MPEG or DVD/DV or Tape/DV)?

Ask yourself what the differences between a TIFF file and a JPEG,
they both share similarities with lousy and non lousy digital video
files.

Nothing we are discussing here is "equivalent" to TIFF, because none of
these video formats are lossless.

DV is "equivalent" to JPEG, both being lossy DCT-based compression
schemes.

If you want to ad a wipe, fade or title you will need to re
render,
that is lousy in the MEPG format.

Do you mean "lousy" or "lossy"?!

I doubt very much it's "lousy".

If you mean lossy, the same is true with the DV format!

You really are clueless...

I'm not the one who thinks DV is lossless!

Luckily Paul has already answered in detail, so I don't have to. I'm
not out to convert you, and I doubt anyone who has read the thread this
far will be convinced by your arguments.

Cheers,
David.

If you say so....

So in effect they are outputting a composite signal as s-video, the
OP could but a separate box of trick (to adjust colour balance and
re-sync the time-base etc.) far cheaper than a high end VCR. I still
suspect that the real problem is in the way the OP is digitising the
video stream to his computer.

Neither VHS nor S-VHS store a "composite" signal. In the colour under
recording method used by both, the chroma and luma are stored
separately on tape.

However, with VHS the bandwidth of both signals is comparatively low.
This means that the high frequency luminance information (which would
normally overlap with the chroma information in a composite signal) is
absent, therefore in theory you don't lose anything by outputting both
luma and chroma together as composite; the two can be perfectly
separated again by a simple filter.

In practice, the S-video inputs of some capture cards still look
better, either because they _are_ better, or because the filtering on
the composite input is bad, or not suitable/optimal for VHS.

The Panasonic NV-SV121EB-S VCR includes a TBC and S-video output (and
is an S-VHS machine). I think it's your only choice. Note that the TBC
doesn't _always_ help - I've seen it make things worse with some
(exceptional) tapes.

There are many other ways of improving the "look" of VHS material, but
a half-decent capture must be the starting point. You can feed the
above VCR into a good stand-alone DVD recorder (rip the result into a
PC if you want) or a good capture card.

Then you can post-process to your heart's content. There are some
useful AVIsynth filters - see the doom9 forums...

http://forum.doom9.org/

...especially the "capturing video" and "AVIsynth usage" sections.

Hope this helps.

Cheers,
David.



cheers, I used virtualVCR for the first capture cos its WDM and my drivers are WDM
and its a lot easier than avisynth. ill dabble with that when I have the time.
capture seems ok, but a bit too yellow, sunlight on grass was very yellow. still, its a vhs-c tape from 1992! amazed
they last this long. Burnt it to DVD as interlaced PAL 720*576
