Sensible-cinema (also known to us as "paranoid cinema" [our own inside joke ha ha]) allows you to apply 
pre-programmed delete lists (e.g. Edit Decision Lists [2]) to DVD's you already own.

I.e. you can play or edit a DVD to "mute out" or skip certain scenes.

This allows you to sit back and relax as you watch a more "sensiblized" showing of your DVD.

To use it, basically install, then insert an original DVD that you want to edited, then run sensible cinema.
It will pop up some windows where you choose what to do with that DVD.

You can either watch it edited in realtime, or created an edited video version of the DVD, on your hard drive.
You could burn that edited file to a new DVD, if you desire and have a DVD burner on your computer,
or just watch it there.

How? Sensible cinema basically takes the original DVD, slices out the bad parts, then gives you the result.
It is essentially a linear editor [1] that applies Edit Decision Lists [2] to videos.  It wraps
a few freely available open source programs [3] to accomplish the editing for you.
It also has a few "realtime viewing" options available, again based on open source software [3].

Note that the whole process can take several hours, so budget some time for it.

Also note that just because an edited video lacks profanity...does not immediately make it an inspiring experience.
I'd suggest carefully evaluating your motives, and going with those.
Sensible cinema does not a clean movie make of a dirty one.  Don't watch it if it's not wholesome! Be nice to yourself!

dove.org and common sense media are good references for discovering the "uplifting" level of movies [4].  
Also note that even if you have an edited copy of a DVD floating around, if you have kids, chances are they
will eventually find (and watch) the unedited originals, so be careful there, and do what is needed.

Enjoy your movies!

== Creating your own edited DVD ==

If you so desire, you could create an edited DVD from the edited file that sensible cinema gives you.

See also LICENSE.TXT for some caveats there.

Windows DVD Maker might help, too.

== FAQ ==

Q. How do I watch these on my TV, not just on my computer?
A. One option is you could burn a new DVD with the edited video file.  See "Creating your own edited DVD"
  You also might be able to move your laptop over to near your TV and hook it in from your laptop.
  Or buy a very long cord and plug it in as an extra monitor from your desktop/laptop.
  You could buy a projector, attach it to your laptop, and then use that to display the video.
  If you're interested in also being able to "beam" it from your computer to your game console (ex: PS3) ping me--I might have 
  something in mind that could help, though hasn't been created yet.  (Playon.tv does something like this, too, but
  I might come up with a competitor to it if desired).
  If you're really good you could try VGA over an Ethernet cable, too: 
  http://ps3mediaserver.org/forum/viewtopic.php?f=6&t=5731#p34279  

Q. I want to give an edited DVD to a friend, how do I do that well?
A. Give them the original DVD and a link to sensible-cinema's website so they can download it.
   You may want to loan them a DVD burner if they don't have one and want one, too.

== Caveats ==

NB that "someone" has to first create a delete list, per DVD.
If one doesn't yet exist for the DVD you want edited,
you could employ somebody to create it, or create it yourself.  Make sure to submit it
back to us when you're done, so that everyone can benefit from it.
Fortunately only one person has to do it, once, for everybody to benefit, and the 
editing process is fairly easy.

Also note that if your DVD has scratches that cause it to skip, the time signatures will be off, 
so we recommend to always clean your discs!

== Motivation ==

The initial motivation for the project was that I dislike deity profanity in movies.
And really any profanity is jarring, if you're not used to it in real life, and can
put you a bit on edge when you watch a movie.  
Also sometimes producers put in certain scenes (read: sex scenes) just to get a rating.
I don't want just those scenes, but still want to be able to watch the movies :)

I tried Clearplay (a realtime filtering DVD player)
but (for me) it didn't seem to cut it.  It costs money monthly (I'm too cheap to pay--and many
many other people don't use it because of that...).  Their
filters sometimes don't cut out all unwanted content (ex: Saints and
Soldiers left profanity in...which wasn't what I had
expected).  Others have noted that sometimes their edit timings (or perhaps DVD players)
are slightly mismatched so that it will mute sections just previous to profanity, while
not muting the profanity itself.  Clearplay apparently also runs a rather 
confusing subscription policy, I'm told [1], as well as selling DVD players that 
are a bit lackluster at times [2].
Clearplay also has little community collaboration/review (though you can email them feedback).
They no longer seem to have a "request a filter" option, though they used to.
They also don't have filters for all movies that I, at times, would like to watch edited (Condorman and Tron
lacking last time I checked...probably because they are too
obscure.) Also, some people watch movies only on computer, and they
no longer have a computer player, only hardware DVD players.  They also don't edit streamed
online movies either (last time I checked, anyway).  So overall I
wanted to build my own that overcame some of these hurdles.
I also emailed them once (2003?) to inform them I'd be making an open source
equivalent, and haven't heard back from them, which I assume to mean implicitly
they're all for it :)

I also wanted to get a prototype out there of some of these ideas so that
others can't later patent them and pretend that they were first inventors :)

 "...I agree that it is not made clear on their website that if you don't continue your membership, you can't continue 
  to use the [previously downloaded] filters"

 "We bought a clearplay player about 2 years ago. It worked great, until it just stopped working. I called their support line, 
  and they told us the model we got was defective, and that the new one was much better and we could get it at a discount, but 
  the next one just died also."

== History ==

Originally the project started off as a prototype that could "watch hulu (online) and netflix instant movies
edited" (it uses/used screen snap-shotting and tracks, using OCR, the on-screen
timestamp of the player, monitors it for specific times, and reacts appropriately).
However, this functionality, though working and available, is disabled currently for potential patent
concerns.
Some older released versions had it enabled, but not the latest releases.
Then I realized I could basically create the same effect using the
(deemed more patent friendly) pre-processing (slice out bad scenes) and/or deletion lists.  It basically was
Edit Decision Lists enforced using playlists and
VLC.  I.e. play from second x to y, now play then from z to second mu, muted, now from q to r, etc.
I just passed VLC a playlist, it did all the work for me, without any necessary real-time tracking.
There are a few released versions that did this.
Then it occurred to me that you could grab the several clean segments
off a DVD, and piece them together to create an edited version.  This also avoids 
realtime tracking, so I included it.
I also added some mplayer EDL playback functionality later.
The playlist option is disabled in later releases, as it was deemed too user-non-friendly.

== Troubleshooting ==

Note that you'll need java previously installed for this to work.  Most people already do though.
If you run into a snag, it might have failed in "grabbing" the DVD, and only got part of it.
Try cleaning your DVD and starting over (delete all files, start again). 
Baking soda toothpaste might help with cleaning it.
If it still errs, report it, along with a screen snapshot and steps of
how to reproduce the problem, preferably.  See feedback section.

It can fail also because a deletion is past end of DVD, or 
Also note that if your DVD has scratches that cause it to skip, the time signatures will be off after that point, 
so clean your discs and try again!

Also make sure you aren't out of disk space.

Also you could try a different computer (desktop computers' DVD drives seem to work better at times than laptops')

Also (for power users) make sure your version of ffmpeg is relatively new, as older versions (r19313) is known to crop wrong.
If you don't know what this means then you're probably ok and don't have to worry about it.

"DVDNAV stream read error!"
  this typically means a dirty or scratched DVD.

You try to play back a sensible cinema-ized video file and it plays back without
 audio or video (example: windows media player)?

 This probably means you're using windows media player, and don't have "codecs" installed
   to handle this type of video.  Not to fear, just download the "ffdshow tryouts"
   and, when it gives you the option, be sure to check "mpeg2 video" and then
   it should "just work."  You could also play the file in VLC Media Player or smplayer
   (there's a button for that).

Thanks to Jarmo for the win32-screenshot gem, the mini_magick gem authors, jruby guys, etc.  
The combination of these tools made programming this actually something of a pleasure.
