Sensible-cinema [5] allows you to apply pre-programmed delete lists
(e.g. Edit Decision Lists [2]) to DVD's you own.  
I.e. you can 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.

It is currently in beta, though will always be free software, even after release.
It also includes a library of EDL's that go along with various DVD's, we need volunteers
to help it to grow!

To use, 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.

Note: please install from the zip files at https://sourceforge.net/projects/sensible-cinema/files/ 
and not from github's "download" button.  See the "install" section, below, for finer grained details.

Sensible cinema basically allows you to create an edited video version of the DVD, onto your hard drive, and you can watch it there.

How? Sensible cinema basically takes the original DVD, slices out the bad parts, then combines it back
into a new file and gives you the result.
It is basically 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 real values, 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].
kids-in-mind.com is also a good reference for profanity levels, though sometimes it misses profanities,
and it also lacks timestamps to know when the profanities occur.  Hence this project.
Also note that even if you happen to 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.

Enjoy your movies!

== FAQ ==

Q. How do I watch these on my TV, not just on my computer?
A. One way is to plug your computer into your TV.
  For instance, position a laptop near your TV and hook it in.  Newer TV's support this.
  Or buy a very long monitor cord and plug it in from your desktop/laptop.
  You could also buy a projector, attach it to your computer, and then use that to watch it.
  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, as the existing one costs money).
  You may be able to create your own edited DVD, see section "Creating an edited DVD"
  Another good option is to purchase a clearplay DVD player, though you must also retain a subscription for it to work.

Q. I want to give an edited DVD to a friend, how do I do that well?
A. Give them the original unedited DVD and a link to sensible-cinema's website.

== 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 create it yourself, or employ somebody to create it.  Make sure to submit it
back to us when you're done, so that the rest of the users can benefit from it.
Fortunately just one person has to do it, once, for everybody to benefit, and the 
editing process is not too bad.

We also have a subtitle parser which really helps locate profanity more conveniently, so that will help you
build your delete list.

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 first!

== 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 desired rating.
I don't want those scenes, but still want to be able to enjoy said movies :)

I once tried Clearplay (a "filter"ed DVD player)
but (for me) it didn't cut it.  It costs money monthly (I'm too cheap to pay--and many
many other people don't use it because of this...).  Casual users no longer have the
option to buy specific "filters" but are obliged to purchase a monthly subscription,
so it doesn't work for many casual users.
Their filters sometimes don't cut out all undesired content (ex: Saints and
Soldiers left several profanities in...which wasn't what I had
expected).  If your standards differ from theirs, you're out of luck.  
Others have noted that sometimes their edit timings (or perhaps DVD players)
are slightly mismatched so that it will end up muting sections just previous to profanity, while
not muting the profanity itself, or so I've heard.  Clearplay apparently also runs a rather 
confusing subscription policy, or so I'm told [1], and their DVD players that 
are a bit weak at times [2].  Their DVD players aren't quite as readily accessible (read: 
can't buy at walmart), nor as cheap to buy as some others.
Clearplay also has little community collaboration/review (though you can email them feedback).
They also did't have filters for all movies that I, at times, wanted to watch edited (Condorman and Tron
lacking last time I checked...probably because they are too
obscure.) If there isn't one, you basically have to request one and then *hope* they get around to it.
Until then, you are out of luck.
They might never get around to it, or it might take a bit longer than you'd hope. Or they might never.
Also, some people watch movies only on computer, and they
no longer seem to offer a computer player, just hardware players.  They also don't edit streamed
online movies either (last time I checked, anyway), nor offer an edited blu-ray player.
I also emailed them once (2003?) to inform them I'd be making an open source
equivalent, and haven't heard back, which I assume to mean implicitly
they're all for it (in reality this project is more like in-home cleanflicks than clearplay, anyway) 
Also clearplay isn't quite flexible enough, editing out only profanity/sex/violence et al (and based
only on their own criteria).  Some users may want to,
for example, skip the intro's to specific movies (like older movies with long songs and no 
content during the intro) because...they want to get to the movie faster.  
Or skip commercials in some personal DVD recording.
Or use it on their home dvd's.  Clearplay does not allow for any of these.  
Also clearplay doesn't seem to users for example leave comments on their filters, to improve them, etc.

So overall I wanted to build my own that overcame some of these hurdles.

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

 "...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."

== Overly Verbose History ==

Sensible Cinema was preceded/inspired by EDL's of editors in the 90's, cleanflicks (both analog and digital incantations, late 90's), 
then mplayer began to support EDL, zoomplayer added a scene-cut editor, 
http://code.google.com/p/movie-content-editor came along, and also many
other editors have historically supported EDL for content creation and/or playback (see wikipedia's "edit decision list"),
such as mythtv/XBMC's EDL support (as suggested by the phantom edit [1], oreillynet.com), 
VLC also added playlists with optional start and stop positions per entry.  Ffmpeg, mencoder were high quality video editing open source tools. 
Once I discovered all of these previously existing programs, I knew the right elements were ready for 
something like sensible cinema.

See also the "related" section, and "motivation" section.

Originally the project started as a prototype to "watch hulu (online) and netflix instant movies
edited" (it uses/used screen snapshots (of specific locations where the digits are expected, based on windows position) 
and then tracks, using OCR of the on-screen (convert to timestamp), to monitor it for specific times relative 
to an EDL, and react appropriately.
However, this functionality, though working and available, is disabled currently for potential patent
issues.  Some older released versions had it enabled, but not the later releases.
Then I realized I could basically have the same effect by instructing a video player (VLC) to "play from second x to y"
ok "now play from z to q muted" etc. (so kind of a stop and go video player, kind of like controlling the remote for you).
It basically was implementing Edit Decision Lists (EDL's) using playlists and
VLC.  
I just passed VLC a playlist, it did all the work for me, without any necessary real-time tracking.  This seemed patent friendly,
so I went with this.  There are a few released versions with this feature enabled.  
They avoid real-time tracking by specifying "play from here to here"
not "skip from here to here" as some other editing players do.

Then it occurred to me that one could grab the several clean segments
off a movie file, and piece them together to create an edited clean version ( a la cleanflix ).  This also avoids 
realtime tracking, so I also included this ability.
The playlist option is disabled in later releases, as it was deemed too user-non-friendly, and because VLC timing
is "different" than standard DVD players, so I decided to just use standardized timing, though it worked fine
for VLC playbacks.
I replaced it with support for mplayer's EDL format

You can see a full list of other features that have been published and demonstrated
in the accompanying file change_log_with_feature_list.txt.  Each feature mentioned works 
in some released version of sensible-cinema though some features have been removed in subsequent versions
(they're all available as rubygems).

Who knows what the future will hold...

== License ==

See the included LICENSE.TXT file for licensing and usage terms (basically it's released under gplv3).
Some other programs are (distributed separately and) used, if present. These are
typically released under their own copy of the gplv2 license, though some have differing licenses.

EDL files themselves are released under the Creative Commons License, however.
See first also the file "is_it_legal_to_copy_dvds.txt" for more information on legal use in your country.

== Troubleshooting ==

If you run into some snag, it possibly could 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 the 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!
"DVDNAV stream read error!"
  this typically means a dirty or scratched DVD.

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

Try playback in VLC Media Player.

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

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 audio.  Not to fear, just download the "ffdshow tryouts" (google for it)
   and, when it gives you the option, be sure to check "mpeg2 video" and then
   it should "just work."  You could also optionally just play the file in VLC Media Player or smplayer
   (there's a button for that).  Installing "AC3Filter" may help if you have no audio.

If the end result picture is too grainy/pixelated or if the overall process is too slow, let me know and I'll work on
making it better.  No really, I have some ideas, but want to see if there's need first for improvement in those areas.

== Thanks ==

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, 
and a breeze cross platform.
Sensible Cinema leverages code from lots of other projects (see LICENSE.TXT)--many thanks to the authors and maintainers of said libraries, and anybody else I forgot to mention.

== Feedback/Development ==

Feedback, including feature requests, comments, etc. welcome:

Mailing List: http://groups.google.com/group/sensible-cinema

If you're a developer and want to help out with programmming or look and feel, etc., please do!

If you want to donate something, please consider donating to a charity of your choice.  
No really.  Do it for this!

== Competition/use of files ==

Note that competition/use of files from sensible cinema is welcome!

In fact, the current end goal is to publish the delete lists (EDL's) as a separate repository with its
own API, meaning that even "for profit" users can use them for whatever other use they want, hopefully
good uses :)  More direct direct competitors are also welcome here.  I only made this because I had to
and nothing like it existed, so if something else springs up, I'm happy to use it instead.
