Yeah, I feel the same way as I don't understand any of the scripting they do, but we'll see the results in other preservation attempts.

 I certainly hope so.  The ones I currently have jog and bounce all over the place.  While I did notice it a bit on the old 4:3 TV, having an HDTV now really shows everything, warts and all.

Also, I wonder if this script, or a variant of it, would work on things like Super 8 transfers?

Even though you are cropping what looks like part of the picture, you are really not, as that part of the picture could just as easily be black pixels: it would make no difference. 

good point! Just do the top and bottom crop before the stabilization, the sides after the stabilization and you should be fine.

some form of the stabilization and degrain stages should work quite well actually.

I have actually cropped both before.  I don't see the need to wait after until after stabilization to crop the sides (unless I am missing something, which I might well be).  One might as well stabilize a (slightly) smaller image and 704x288 is still mod16.  Thanks! :-)

You need to crop after stabilization because the whole image is being moved from side to side during that process, which will leave you with a shifting border of black pixels and 'image' pixels. AFAI understand it.

Drat!  I wish I had known that before rendering... Oh well, off I go again.

Thanks, satanika!  I appreciate the help.

 Very cool.  What would it take for one of you folks to try it?  I guess you'd have to start with source material, of which Puggo's is the best.

This looks great so far.  Stupid question: you guys do force film the video in DGIndex before using the script, don't you? 

I did this as a matter of course without thinking about it.  I cannot see why it would make much of a difference to functioning of the script, but just checking.

edit - G-Force, are you planning to work with the PAL GOUT for your ROTJ script?  Unlike the other two movies, the PAL is supposed to be better quality.  I would prefer to have an NTSC output, but one could easily work PAL to NTSC conversion into the script.  This would mean one could work with the best source material and it could produce PAL and NTSC outputs by just adjusting or deleting a few lines.

I also hope you will give me permission to release an MKV of this.

I'm always down with MKV.  I'd like a copy if possible.  :)

Since I rip all my DVDs to MKVs anyway, and watch them on my TV with my FreeAgent Theater+, I'd love it if more Star Wars preservation projects and fan edits were released as higher-bitrate MKVs with uncompressed audio.

So I fully endorse the MKV idea!

Yes, force film is a must. I don't own the PAL versions, is there a thread that describes what makes the PAL ROTJ better?

Permission not needed, but if it makes you feel better, you've got it.

I seem to remember that the PAL GOUT disks were just stretched NTSC GOUT video...which was a huge disappointment to everyone who lived in PAL land.

G-Force, is there anything you can share with us about your progress on the V3 ROTJ script? What are some of the time consuming tasks in tweaking your script for ROTJ that's different from the other two movies scripts?

Thanks.

I love everybody. Lets all smoke some reefer and chill. Hug and kisses for everybody.

I think I would rather IVTC in AVS then use DGIndex's Force Film since its very hit n miss. Although I have never tried it on the GOUT so it could work well in that instance.

Any thoughts on that g-spot?

CompMovieGuy: What?  I know you've done a lot of great conversions, but this doesn't make any sense.  I'm assuming I'm misunderstand you, but for others who might not know...

DGIndex's force film doesn't inverse telecine video!

DGIndex INDEXES mpeg video so a frame based program like avisynth can work with it frame accurately and non-linearly as it would AVI content.

Force film or honor pulldown flags just determines if avisynth (or whatever program) will soft interlace progressive content whenever a pulldown flag is present.

I.e., add pulldown & interlacing where it isn't present in progressive material.

The only reason to use "honor pulldown flags" instead of "force film" is if your source is not 100% progressive (less than 95% is the rule of thumb, DGIndex will give you this number).  I have seen films/tv shows that have patches of hard telecining within progressive content.  (Anime is notorious for variable frame rate).

This is a problem because mpeg can have variable frame rate, AVI content must have a constant frame rate.

Using honor pulldown flags will make avisynth (or whatever) generate 29.97 interlaced video adding soft telecining in progressive areas and leaving hard telecined areas alone.

From 100% telecined you can then use an IVTC filter like telecide/decimate which will restore progressive frames from material that is soft telecined during playback.

Mind you, that still assumes that the interlaced portions are film sourced.  They can just as well be true video (59.94 unique fields) in which case you will need to deinterlace to 29.97p or use something like AnimeIVTC().

Or to rip off Doom9:

FORCE FILM WHEN YOU CAN, IVTC WHEN YOU CAN'T FORCE FILM, AND DEINTERLACE WHEN YOU CAN'T DO EITHER.

http://www.doom9.org/ivtc-tut.htm has more info for those looking to read up.  It refers to DVD2AVI but that's pretty much the same as DGIndex (which is build from it).

No DoctorM, Im with you and your Doom9 quote

The only thing is that on some occasions, even when it reports around 99%, Ive seen DGI Force Film mess up in the final product

But like I said, I havent messed with the GOUT so Im not sure what it would report or if IVTC in AVS would be better

The GOUT ESB seems to be pure film.  DGIndex is fine for percentages over 95%, and IVTC methods in Avisynth are not perfect either.  I have never seen DGIndex cause problems at percentages over 95% and I have used it a great deal.  My question was just meant to rule out the possibility that the script required 29.97fps, incredibly unlikely though that was.

Permission not needed, but if it makes you feel better, you've got it.

There was a thread about the PAL ROTJ GOUT being sourced from a different master than the NTSC GOUT and, alone of the PAL versions, being better quality than the NTSC, but I cannot find it. 

Thanks for the permission.  I feel it is polite to ask from a community point of view.

Okay, CompMovieGuy, it sounded like you were assuming DGIndex could physically inverse telecine.

Mind you, if I had notice you also asked g-spot a question, I probably wouldn't have said anything. :-)

Btw, I HAVE seen over 95% cause problems.  I usually like to know WHY a video isn't reporting 100%.

In my experience, with percentages that high it is usually that studios tack on logos and stuff at the start that are hard telecined, and the rest is normal film, unless it is anime you are talking about. 

Perhaps we should start a new thread for discussing this further. :-D

LOL his script is not V3, that is my versions of the encodes, his actual versions are a lot higher than that, v3 is pretty much used for the set I will release.

I have the PAL versions of the GOUT as well as the NTSC, I would really like to know what the differences are in Jedi also.

TV's Frink is good at looking up old threads, where is he when we need him LOL.

Lol indeed. :-)

I've got no idea on this one.  I guess you could try the search function, although it kinda sucks.
