DVD Shrink 3.0 Beta 1

[dvdshrink]

DVD Shrink 3.0 Beta 1 is now available, for those who wish to test.

http://www.dvdshrink.org/
http://www.dvdr-digest.com/software...?file=dvdshrink

The main changes are:

Version 3.0 Beta 1 - 9 Aug 2003

No more compression levels. Instead we have four new settings:
- No compression - original video.
- Automatic - DVD Shrink will choose the best compression ratio.
- Custom - you can select desired ratio (with a slider)
- Still Pictures - as before.

Better quick analysis.
The sample points for initial quick analysis are carefully chosen, and sparse analysis results are interpolated between samples.

New "Analysis" button.
This performs a deep analysis, which (a) guarantees that the predicted target size is met and (b) significantly improves video quality.

New "Analysis Results" file format
The new format is more flexible, used to save results of the initial quick analysis, also deep analysis results or partial analysis results (if you cancel analysis, partial results are saved). Also better checking in case of conflict of CRC values between two DVDs.

One-pass encoding.
Output files are written to HD in one pass, so no longer necessary to make a second pass to fix navigation ptrs. This reduces total encode time by about 5 mins.

Multi-threaded preload buffer (in both analysis and encode modules). While one batch of data is being processed, the next batch is pre-loaded on a seperate thread. This seems to work especially well during quick analysis, where the waiting time for drive seek operations is significantly reduced.

RCE region protection removal, special thanks to Mr.Bass.

New "New Frame" menu option - creates another instance of DVD Shrink, but in the same process. This is used by re-author module which now supports drag 'n drop, or cut & paste, from any window (re-author from multiple disks).

Video preview window shifted to the right-pane, which is where it belongs.

Fixed various strange behaviours in the DVD and Streams View. Also removed the "Compressed" column, since takes up unnecessary space.

Compression % values inverted, so they now represent the ratio of output size to original (small % = big compression).

File reading code now supports output from DVD Decryptor in "Auto" file-splitting mode, or non-split VOB files.

Fixed bug in re-author where only 32 titles could be played in sequence. The limit now is 99.

Added "perform deep analysis" option in backup dialog, thus analysis and re-encode become one sequential operation.

Added "shutdown when complete" option in backup dialog.

Added "remove macrovision" option in preferences (all versions since 2.x have removed macrovision, now it is an option).

Added "remove P-UOPs" option in preferences.

Added "split VOB files" option in preferences, on by default.

Fixed possible problem which may have caused gaps in audio playback.

Removed option to disable menu subpicture streams, as this stream usually contains the menu buttons.

Added option to completely disable video preview.

Moved all hard coded text strings into resource file, so future translations will be complete.

Removed "view Raw DVD" option.

Added "Unreferenced Material" folder, which appears in the main view if material is found on the dvd which does not seem to belong to any menu or title. Previously the existance of this material would cause errors in target size calculations.

Removed "error margin" option - no longer required.

Added "Combine Shared Titles" menu option, which is on by default. Turn this off to seperately list all multi-angle titles (or titles which share the same video with other titles) in the main view. You will need this, for instance, if you wish to re-author only Angle 2, etc.

Fixed TMAP table generation for re-authored titles with angle greater than 1. Seek in PowerDVD etc should now work, whatever the angle.

Various other tweaks and enhancements.

Please enjoy :-)

one thing you missed out, it still doesn't put the blank in the writer :D

DVDShrink, how much would you say the video quality improves? as you mention significantly yet 2.3 was very good anyway

[JediSthlm]

SuperThanxAlot, Keep the great work up. You are the man :)

Would have liked the option to disable titles with a picture ah-la Recode....

How many minuts did it take before the first request for more features appeared ? :D

Does this mean all translations will just be those resource files and within DVDShrink you can just have one bundle or will there still be 666 bundles of various languages to download?

Can you make the Internet Fraud Complaint Center link clickable in the About dialog.

[gnutellafan]

WOW - DVDShink, you kick ass.

Couple of questions.

-Are layer changes removed?

-Any chance of being able to choose the start point of the movie? (ie I want my disks to start with the film, not the menu, I can do this with ifoedit but would be nice to have an all in one tool)

And I agree w/ Anijake, it would be nice to be able to replace a title w/ one picture such as in recode.

[dvdshrink]

ok strike "significantly improves video quality" and replace with "according to my calculations..." - I'll leave it to everyone else to judge.

DVD Shrink 3.0 at maximum compression will output more or less identical results to version 2.3. Its the in-between ratios, where there is some leeway about from where to actually gain the compression, which should be improved by deep analysis.

And... I have just found a bug in re-author, which does not entirely remove all disabled streams.

That's why its a beta ;-)

[dvdshrink]

I haven't decided yet...
At the very least, it means that Japanese text can be displayed in all the main views "ƒrƒfƒI" "‰¹�º" etc, rather than english text with japanese dialogs as before.

Can you make the Internet Fraud Complaint Center link clickable in the About dialog.
I've no idea how to do this! Is there an MFC control for it?

Hopefully Japanese text will display better than it does in the doom9 forum.

woohooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!

I will freely admit I hate paying for software, no matter how cheap.
But since I now have a PayPal account, I would definitely donate some if you set up an account.

[SirCentipede]

Wow... I'm impressed by all the changes and new features... just downloaded it and I'm totally eager to test 3.0. now... cya l8r !

BTW I like the idea of a donation account for Mr. DVDshrink, too...

[daddy_fizz]

yeah this is sweet :D so many new features...

the idea of a payapal account has been brought up many times... but dvdshrink always keeps silent about it...

[quantum]

I just did a comparison between Recode and Shrink using Matrix NTSC. Both produce playable backups including the button over video. Comparison of the video shows similar quality. Some frames are handled better by Shrink, some by Recode.

Neither program retains closed captions, something I would like to see addressed.

Recode can compress disabled titles better by using a custom solid color picture. Something I'd like to see in Shrink.

Overall a step in the right direction for Shrink. If the custom still picture for disabled titles can be added in the beta, it might be a tough choice between Recode and Shrink.

[daddy_fizz]

i prefer shink, the interface is much easier to use than recode (imo)...

recode is a little too buggy for me too...

~Fizz

[zeronegative]

Comparing DVD Shrink with Recode:

+ DVD Shrink has a friendlier user interface
+ DVD Shrink has ability to disable video preview
+ DVD Shrink removes encryption
+ DVD Shrink shows est time remaining

- DVD Shrink cannot use a still to disable video
- Video preview controls are not as smooth as Recode

If the two minuses can be solved (and, if possible, DVD Shrink can be maximized to use it fullscreen) than DVD Shrink could be a true winner.

Good work, dvdshrink!!!

[mrbass]

when Automatic is set shouldn't the greenbar go down when one unchecks audio like No Compression, Ratio and Still Pictures do?

ok instead of making it clickable that IFCC how about just so it's selectable text so one can copy and paste it.

[dvdshrink]

Anything set to "Automatic" will try to fill all available space so the target size is fit exactly.

If you disable an audio stream, video set to "automatic" will adjust its ratio accordingly to fill the space you created... thus the green bar does not appear to move, if a fit was made, but you will see the %video compression values updated in the streams view.

Anything NOT set to automatic, should remain as you last set it.

Generally, the only reason for using custom "Ratio" rather than "Automatic" would be if you wanted more control over the distribution - e.g. greater compress the extras, etc.

[Bear263]

DVDShrink, I think you have done a hell of a job. My thanks go out to you.

[Antonio S.]

@dvdshrink:

Would it be possible to add a "burning" feature?

[MackemX]

Originally posted by zeronegative

you can manually resize it to full screen but it distorts the preview screen

to fix it just drag the top & left of the preview window to resize it so it's back to normal ratio

I guess this is the best way for now until a full screen is available

a good thing is it that remembers what your last screen layout was

[SirCentipede]

I just tested the new DVDshrink 3.0 beta on 24 Season 1, Disc 1 (RC2, 4 episodes, no extras no foreign languages 6,93 GB), because i did it last night with IC7 (my tool of choice when doing mulit episode discs) and wanted to compare the results to DVDshrink 3.0.

I must admit that multi-episodes are difficult for every transcoder and 24 is especially difficult, because you can't erase extras or foreign languages. Both IC7 and DVDshrink 3.0 transcoded everything at round about 60%, it's a value where you can expect macroblocks and artifacts. So here is my very personal opinion comparing the results:

DVDshrink 3.0 really impressed me on this one in comparison to older versions of shrink. I did a deep analysis of the DVD and it only took 25 min. to analyse and another 25 min. to transcode, which is pretty fast for the quality you get afterwords. I think in this version shrink is nearly on par with IC7 regarding picture quality.

Both seem to be equally sharp and there is virtually no difference to my eyes between the original and the transcoded movie.

IMHO DVDshrink 3.0 handles slow scenes slightly better than IC7, the picture is smoother, because IC7 tends to produce more artifacts in the transcoded movie.

On 60% compression there are some blocks in both transcoded movies, although IMHO IC7 handles action scenes better, but DVDshrink 3.0 definatly improved compared to 2.3.

But I'm a little bit irritated by the fact that DVDshrink desaturated the picture slightly, while IC7 has nearly the same saturation as the original. You won't notice this when you just watch the movie and don't do picture comparison (I would like to show some snapshots i did, but i don't have a host to put them on, sorry).

THE advantage Shrink has compared to IC7 is the user interface, the ability to rip (3.0 even with removal of RCE protection) and last but not least it's its speed: you put a DVD in your DVD-Rom and you'll have a transcoded movie with very good picture quality in about 50 min. (with deep analysis) ready to burn.

To sum it all up i really like the improvements on DVDshrink 3.0, especially the "auto fit-DVD feature", the "custom ratio slider", the ability to remove RCE in this new version and the possibility to choose between normal and deep analysis.

So I think that i can live without IC7 if i must to, but definatly not without DVDshrink 3.0, although I'm happy to have both in order to decide which one is suited better for a given movie.

P.S.: I hope the desaturation issue is solved in the final version of DVDshrink 3.0.

[Exo]

I wasn't able to put unreferenced material
via re-authoring onto a new disk. You just
can't drag and drop such items and when
right-clicking on it the copy option is
greyed out.

Nevertheless great work, dude!

[Protosstic]

Only thing it needs now is VBR encoding. :)

[Yannis]

Well... if VBR (pretty much like in the IC sense) is implemented, I am not sure why the all the other products should continue to exist :D :D :D

A remarkable tool for free!!!

[brush]

Hi mr dvd shrink

Thank u for your huge work

Just a question about ANALYSIS

IN REAUTHOR MODE
should we analyse the movie twice before and during the compression process in order to get the best image quality ?

[tumbar]

Thanks for all your efforts. This version best of all. Great tool.

Hats off to you sir!

[luphy]

On load-up, the program will do a basic analysis of the movie. If you choose to do a deep analysis after that, before you press the Backup button, it will then do a thorough analysis. Then when you go to do the backup, the option to do a deep analysis should be greyed out because you've already done the deep analysis.

that's true, however, the reason deep analysis is offered as an option by the backup is so you check it then say "Backup". That way you don't have to wait 20-30min for a deep analysis then press backup.

[corigan]

Thanks a ton for the release dvdshrink, looking forward to testing it out and of course future releases. I love this program and it is the transcoder I use by choice.

As for the paypal acct, maybe mr. dvdshrink is afraid that if he used a paypal acct his anonimity might be easier compromised, if that is what he is wishing to achieve.

Either way if there would be a way to do donations I for one would glady donate, but appreciate all the work he puts into this great program even if he doesn't want donations, we can all give him our praise and thanks.

I am finding the same in "backup mode".
Went through the fast analysis when the disk was opened, now Shrink is doing two 40min analysis. One for 3.8gb main movie title set and one for the 3.4gb extra title set. The movie is "To Kill a Mockingbird" and the extra title set is the director and actor's visual commentary, located in the main movie title set 2. This scenario may also apply to a disc with both full and widescreen versions.
Is this intentional....?

Anyway great job on v3.0

[luphy]

Papillon,

What happens if you choose deep analysis BEFORE you go into the Backup window? Does it take just 40 minutes to do the entire disc or does it take longer? I have not done any backups with more than one titleset yet with ver3beta. That is a good question you have.

I'm glad DVDShrink added the autoshutdown option now that Shrink has the longer Deep analysis option.

I'm gonna have to use the program a bit longer cuz I'm having a hard time coming up with any suggestions. :-) I actually like to review the results of the transcoding before I burn to a disc so I don't really have use for all-in-one rip/transcode/burn programs. There's always AutoShrink and ImgTool for those wanting that I guess.
Cheers to DVDShrink for implementing all the requests from his loyal but annoying fans!

[papillon]

luphy
Just tried what you suggested, and seems to be doing the same 40+40min
analysis. I don't really have time to keep an eye on it now. But I am going to try a disc with both full and widescreen versions to see what happens.

D'oh! *beats his head to the wall*

Sometimes you forget the simplest solutions. Thanks. I'm still curious as to if stream disabling will be implemented, I think this is at the top of the feature request list. dvdshrink, do you intend to work on this?

[JackRipper]

Hi,
I am new to this forum but have been in the scene and certainly a user of Shrink for quite sometimes now and would like to express my thanks to Mr. Shrink for doing a great job.

[snidely]

I actually like to review the results of the transcoding before I burn to a disc so I don't really have use for all-in-one rip/transcode/burn programs.

Agreed. Why would you ever want to burn a disc before checking it out? I've saved more than a few bad burns by examining my work before committing it to disc.

Mr. DVDShrink, you rock!!

[dwflo]

Got a silly question.
How is it that DVD Shrink has such a small file size compaired to all those other packages out there? Has it to do with all the bloated crap written into them others? Shrink works so well, with such a small footprint, I am amazed at what it is capable of doing.
May not make much sense to some, but I am not a programmer, so just curious.

[dmfreck]

Hello everyone, first time poster...

I'm familiar with shrink 2.3 but this one has me stumped: when I go to "reauthor" a movie with this new version (so as to only get the movie, itself) it opens up a new but *blank* copy of dvdshrink with no streams listed on the right. Anyone else have this problem? I read this thread all the way through but didn't see anyone mention it. Much thanks in advance for any help....

-M

*edit*

Ah, nm...answered my own question - you have to open up the +'s and actually grab the title you want to reauthor and drag it into the new dvdshrink window. I was mistakenly trying to grab the entire "main movie" stream and have having no luck. Grabbed "Title 1" under main movie and was able to drag it. Thanks and greetings!

[dvdshrink]

DVD Shrink is actually a lot bigger than it needs to be, since it is statically linked to MFC libraries.

The dynamic linked build is 134KB. However, it requires the user has MFC7.0 dlls installed. I would attach it here, but don't seem to be able to.

[dvdshrink]

If you think about DVD Shrink re-author mode as like Windows Explorer, then everything becomes clearer. Create a new window with the re-author button, then drag'n drop (or copy and paste) titles from any other dvd shrink window.

Drag 'n drop also works between two re-author windows: hold the SHIFT key to copy, otherwise you get a move.

Drag 'n drop also works within the same re-author window, to change the order of playback of titles.

[snidely]

Shrink works so well, with such a small footprint, I am amazed at what it is capable of doing.

Size isn't everything! :D

[luphy]

I too was impressed by the size of the program. Considering what it can do, and comparing it to all the bloated software out there - it just shows you how extremely efficient DVDShrink has been with his code. All in one executable file without any needed extra installed files. Amazing work. And the quality with deep analysis really is very nice. Now I have to consider whether I want to go back and backup some movies I already made that required higher compressions.

Oh I finally thought up of a suggestion - though maybe it can be done already. Sometimes on DVDs with both widescreen and regular versions, I cannot tell which is which because even during playback in Shrink, the movie fits to the playback window. Is there a way to maybe click on the titleset and have it display the version? As it is now I just go to my DVD playback program and choose to play each titleset to find out which is which.

[mrbass]

yes..that's a good suggestion. I have trouble sometimes too determining which one is 16:9 or 4:3. Some indicator would be nice if possible.

[brush]

If Mr shrink can help me

I want to keep just the movie ( no menus or extra stuff )
so I open up the REAUTHOR WINDOW , and I copy paste the movie in it

The problem is I CAN'T DO , a deep analysis of the movie, the button is greyed in the REAUTHOR WINDOW and in THE BACK UP WINDOWS

Can anyone explain me , at which time the deep analysis should be made

[helloween]

First, thanks for this new version, I am very happy with all the new options that it includes.

My question is: when using 'deep analisys' improves video
quality to have predicted better the target size or because to pass on each photogram is applied more optimal compression according its complexity?

Finally, three suggestions for future versions:
- Creation of folders VIDEO_TS and AUDIO_TS in target folder.
- To be able to replace titles with an own screen, like Nero Recode.
- In the re-author way to be able to choose the audio track and subtitles that are wanted by default. This is very easy adding pre-command.

Thanks.

Sorry for my terrible english!

I don't have this kind of issue :confused:

Mr shrink , could you answer my question please ? ;)

[dvdshrink]

The problem is I CAN'T DO , a deep analysis of the movie, the button is greyed in the REAUTHOR WINDOW and in THE BACK UP WINDOWS
If the button is grayed out, it means the movie has already been fully analysed.

Basically, it doesn't matter when you do the analysis:

If you analyse the whole disk, and then re-author a title, the analysis results will carry into the re-authored title.

If you re-author first, and subsequently analyse the re-authored titles, then the results of that analysis will also go back into the original full disk (if that window is still open).

DVD Shrink is aware that analysis results are valuable, since they take a long time to generate. It has a lot of internal logic which ensures you never need to analyse the same parts of the dvd more than once, even if you have titles open in several re-author windows.

Note also that if you cancel analysis, then results will be saved up to the point where you cancelled. The next time you do deep analysis on the same dvd, it will continue from the point where you cancelled (even if you exit dvd shrink and restart the next day).

It seems I can't post attachments.

Anyways, when I set in the preferences "Desired DVD size" to 2200 MB the automatic value is 41% (exceeding the size), if I set it to DVD-5 it raises to 59%;

in any case the smallest value of Ratio I can choose is 41%, while I
want to set it so that the resulting image size is 2200 MB (so a size reduction of 67%).

Thanks very much.

[The Belgain]

First of all, really nice program DVDShrink! I've just done a couple of backups with it and the quality is not bad, and the simplicity and speed are great.

One feature request though: would it be possible to have an option for resizing to 1/2 D1 res (ie CVD res)? This would be especially useful to get the credits down to a small enough size while not resorting to a slideshow. Is it possible for a transcoder to change the res of a video stream (in this case a nice simple resize - half horizontal res)?

[dvdshrink]

Transcoders can, in theory, change the video size - however this is beyond the capability of dvd shrink engine!

About the custom slider not going below some percentage: this would be the minimum percentage (maximum compression) that dvd shrink transcode engine can get out of the original video. This value is determined during analysis. Your target size was just too small (or the dvd too big, whichever way you look at it).

[The Belgain]

Are there any standard presets about giving priority to the quality of the main movie rather than the credits? On the test I did the compression percentages were about the same for the main movie and for the credits (though maybe this is partly becuase the credits are smaller on the original DVD).

I think many people would rather sacrifice some quality on the credits in order to make the main movie have better quality.

edit: does that mean there are currently no plans to add resizing to DVDShrink? Do *any* of the transcoders have the ability to resize?

[dvdshrink]

Automatic mode sets everything to roughly even quality... the %values may be slightly different for each item, but this is based on the maximum compressability of each respective item.

If you want to set priorities, you will need to override with a custom ratio setting. The easiest way is to leave the main movie in "Automatic" and set the extras to minimum custom ratio.

[The Belgain]

Ok thanks, that's what I did on my last one.

Yes this is known! :D :D :D

By VBR it was (freely(BR?!)) meant to remove an amount of information variable with each frame (like IC) and not constant throughout the stream. Thsi woudl produce an even better quality.

dvdshrink is a really amazing tool and as I said in the previous page, if this is done in some next version it will be "unique" outstripping thus any competition (mind that the word "competition" was never the author's intent!!! he does not even accept donations !?!? :D:D)

But we can only do that in Re-author mode. Would be really nice to have that ability in Full Disk mode. (And to splice segments as well).

Surely it would produce an uneven looking movie. Some frames would look great, and others might be pixellated (given that movies are already encoded with VBR). How would you determine which frames got more bits, and which got less? I don't see how the concept of VBR can be applied to transcoding (except as has been suggested by manually noting where the credits begin and telling the engine to change its compression ratio to something else - that's not hard I'm sure. But to try and create in - one step - from CBR to an automatic function that does this, is rather foolhardy IMO - and probably couldn't be called VBR either).

Am I talking sense, or is my Fat Arse spouting liquid digested nutrional products?

[Yannis]

Check the thread: http://forum.doom9.org/showthread.php?s=&threadid=58964 where some explanations are given as to how transcoders work. IC uses some heuristics to remove different data from different frames. In any case, I am sure this is coming later in dvdshrink ; its brilliant author has proved that he can do anything and has enough imagination to do even better heuristics than IC :) :)

[dvdshrink]

DVD Shrink 3.0 is already a fully VBR transcoder <if> you do a deep analysis before backup.

If you just do quick analysis, then it is still VBR, but no guarantee that the chosen bitrate is the most suitable for any given point in the movie.

I'm pretty sure that the quality will increase, and the time to rip the dvd too.. but if the user want quality over speed.. go.

DVDShrink 2.3 give a good quality video.. but often lot of macroblock in the anime movie. CCE is the best for that... but I'm not able to recreate the menu because there is layer break in the DVD... for now I was stuck with DVDXcopy because IC7 crash since the last update on my PC :(

I'll give a try to the 3.0 version, but will it be hard to add the multi-pass feature ?

I notice with 3.0 beta 1 that the resultant files appear to have incorrect "VTS sectors". This is easily fixed in IFOEdit etc. but I thought I would mention this.

Edit: Never mind; this appears to be fixed in 3.0 beta 3.

dvdshrink, thank you for such a amazing program. my problem with 3.0Beta1 is; i backup my Pulp Fiction DVD.i just leave DTS audio track and remove dolby digital 5.1.normally with older versions with dvdshrink DTS track become default audio track. but when i playback dvd in dvd player there was no sound. i change the audio track 2 with my remote control and can hear DTS. in screen display track 1 displays dolby digital 5.1? its a small problem but i would like to inform you. meanwhile picture quality is awesome. thank you again. (sorry for my poor english.)

Yup, I have exactly the same problem. I removed the French DD5.1 track from the Matrix DVD (which is the default track), and when the DVD starts playing I get no sound unless I manually change it to English.
