Does anyone know how to remove Japanese subtitles from Japanese LaserDiscs?

Thanks.

You can't. They're non-removable.

This is true for watching the actual LD.

Assuming that the subtitles are in the black areas of the letterboxed
picture, you can remove them if you transfer the movie to DVD. This
would be a laborious process of using Photoshop for NEARLY EVERY FRAME
to black-out the subtitles by setting RGB = 0,0,0. I would imagine
that this process would take a couple of years to complete depending
upon the length of the movie and how often subtitles appear on the
black areas! Not fun.

People are so used to being able to do things like this in our digital
world, but LD is an analog format. I'm afraid you are out of luck.

Er, well that's not true at all, you can frame serve the AVI through
AVIsynth using the "Lettebox" command to mask out the black areas.
Also VirtualDub has masking and cropping to cover unwanted areas.
This is a simple thing that is done all the itme, even to just masking
out the switching lines at the bottom of VHS tapes. This doesn't
apply in this case, but if applicable it's hardl ythe major task you
describe.

No, it's 4:3 screen and they are white background.

Ok, I guess no means no.

But one thing is that there're some Japanese DVDs that Japanese folx
transferred from Japanese LaserDiscs. On these DVDs there're Japanese
subtitles that can be turned off. So I guess these subtitles weren't somehow
bundled to LDs. I don't know. One such title that comes to mind is:
Deep Puprle - California Jam 1974 by VAP Video.

This sounds like LD+G close captioning, which can be turned on or off
if your JAPANESE LD player supports it.

My DLP projector has a blanking function I activate to cover up the
subtitles if they appear in the letterbox bar.

Unless...

You run it through something digital. Just playing it to the screen is
indeed an of luck type situation. (There is a way to do it there to, but
it's in my head- I don't think anybodies built one yet.)


otoh,
If you can edit on a PC or something you can remove the offending
titles. (Gee, hand removing each 'frame' via photoshop seems waaaaay to
hands on labor intensive.)

I guess not. My LD player is Pioneer Elite CLD 52. I actually will be
transferring these LDs to DVDRs myself using TV capture card and soundcard.
Thought I could get rid of those subtitles.

LD+G works similarly to closed-captioning, except that the decoder would
be built into the player rather than the TV. If your LD player doesn't
have an LD+G decoder, you won't ever see the LD+G captions. Any
subtitles you see when playing a disc now are burned into the image
permanently, and are not LD+G related. The only way to not see them is
to cover them up.

There are a couple of filters for VirtualDub/AviSynth that can do a
decent job removing logos from video. Sometimes the results are pretty
astounding, especially for translucent bugs. However, for white hard
subs on a 4:3 background, the results of the removal would probably be
far more distracting than the original subs. I'd say it's not worth
the trouble to even try. And that's coming from someone who has spent
a while trying.

Intriguing. Because i would think that Deep Purple Cal74 (LD is
VPLR-70114) had no subtitles at all but must have come with a lyrics
insert, maybe someone made the lyrics into optional subtitles on a DVD
? I may be wrong as i don't own that disc. Any other title that comes
to your mind ?

You could also use a mask in Premiere which would take absolutely no time at
all.

I use VirtualDub to feed AVI to TMPGEnc. I don't use any filters though. What
filters would you recommed there? And those subtitles are on the image. If they
were on some black background, that wouldn't have bothered me too much.

Ahh... No there's no lyrics on Cal Jam. There're subtitles during the song
announcements which are removable. So if there's no subtitles on LD that
means that VAP video either transferred it from LD and then added subtitles OR
VAP video simply recorded it from the same source that was used for LD. The
quality of DVD is ok. It could be better if they boosted up bit rate from 6mbs
to 8mbs.

PS. I want to remove subtitles from 12 Wasted Years LD I got from you.

Or,

you could get them into the computer and REPLACE them.

Look into editing software.

Replace them with what? If they're in the letterbox bar you'd replace
them with pure black, which amounts to the same thing as covering them
up. If they're in the movie picture, you're screwed. "Replacing" them
would entail sampling the pixels around them and individually painting
them out of every video field for the entire movie.

Good luck with that. Check back with us in 10 years when you've
finished.

With what? The original picture information is permanently obscured by
subs, as Josh says. "DeLogo" and a few other VirtualDub filters are
the best hope, but even they are likely to come up with
less-than-satisfactory results in this case. Even if you put new
(non-Japanese) subs over top, it's mostly gonna look like you put new
subs over top of either hard Japanese subs, or a weird blurry mess.

Computers, as much as I love 'em, aren't a panacea.

I suppose it would be possible to have an algorithm detect the subs,
and replace them by some sort of interpolation of pixels around.
Results would not be perfect but it could run frame by frame,
requiring no attendance.

Remember in the old days before color cinema, prints would be painted
by hand...
