VHS to DVD: does it worth?
_MerlinO_
wondering which is the best destination format to do it: SVCD or DVD?
I know that a VHS video (PAL) has about 300-320 dots per line and 576
lines, so I'm wondering if does it worth to acquire in DVD resolution
720x576 instead the SVCD resolution 480x576, more similar to VHS
resolution.
Can you help me?

Another possibility is Half D1 (352x576 PAL) which most people consider
good enough for VHS. That resolution is DVD compliant, and since you're
using only half the resolution of full D1 you can also halve the average
bitrate and fit twice as much on a DVDR. Three to four hours of VHS
material on a DVD shouldn't be a problem if you use a 352x576
resolution. I would recommend using VirtualDub or Avisynth for noise
reduction though, otherwise you'll get garbage in, garbage out (but
that's for you to decide, because noise reduction takes time).

Have you tried Vitrualdub?

I use Avisynth now, but this used to be my VirtualDub noise reduction
filter chain:
1. deinterlace (mode: unfold) (internal filter)
2. smart smoother hiq

(Website apparently down at this moment.)
3. temporal cleaner

4. deinterlace (mode: fold) (internal filter)
#1 doesn't deinterlace the video (it shouldn't be deinterlaced!)
but separates the fields, which improves noise reduction.
#2 is a spatial cleaner and #3 is a temporal cleaner. The default
settings are pretty good for both VHS and TV captures. If you want
to fine tune the filters, read the help files.
#4 folds the fields (which were unfolded in #1) back together.
There are plenty of other filters, but after a while I got fed up
testing new ones, as I was happy with the above filter chain.

Thanks for sharing this!!! I'll try it when I get my new hardware and start
transfering my VHS tapes to DVD. But just one thing I'm not sure I
understand... why do you say that "(it shouldn't be deinterlaced!)"?

Well, if the source video is interlaced, it should be kept that way on
DVD. Playback at 50 fields per second is smoother than playback at 25
full (deinterlaced) frames per second. VHS is usually interlaced, so
don't deinterlace it. The settings for the deinterlace filter I'm using
do not really deinterlace the video, they just unfold both fields before
filtering and fold them again after filtering to prevent problems.
Interlaced video has a so-called combing effect when there's motion,
like this: http://www.dscaler.org/screenshots/TitanicBefore.jpg
Deinterlacing the video to remove the combing effect should not be done
if you're transferring interlaced video to DVD.
If the source video is not interlaced there's no combing effect when
there's motion. Movies usually aren't interlaced, although movies made
for TV probably are. Anyway, if you don't see a combing effect in your
captured AVI file, you're video isn't interlaced and you can omit the
deinterlace (unfold/fold) filters.
There's an exception for NTSC (3:2 pulldown, IVTC) but I'm not familiar
enough with that to give a perfect explanation. But read this:

telecine is better than my camera capture from a movie screen could be.
I then want to capture the mini DV tapes from my Sony VX 2000 camera into my
Premiere 6.5 (Pinnacle 500) video editing, no problem.
What improvements can I make to the video quality along the way before DVDIt
authoring.
Is VirtualDub good for this too or can anyone suggest worthwhile techniques?
Thanks to all
