GPL command line M2V transcoder

[Nic]

@DVDRFreak: Excellent work, expect a new build tonight.

@2Cool: Thanks for your input, I know that all your feedback and guides are very highly regarded. :) Could you name some more DVDs you've had trouble with. Nemo here is still in Cinema...Also why is IFOEdit bad for NTSC stuff? Is the issue mentioned here: http://forum.doom9.org/showthread.php?s=&postid=391721 (sorry, im a authoring newbie, so have to check :) )

-Nic

ps
The reply from Metakine (sounds promising :) ):

Hello Nic,

I'm glad you have been able to compile the module on Windows - it had actually never
been tested on a little endian processor...

The code was up, I just screwed up with the link when I updated the web page (I was
pointing to M2VRequantizer.tgz instead of M2VRequantiser.tgz - and it worked because
of another typo - anyway!)

The source code is there as I speak in:

http://www.metakine.com/files/M2VRequantiser.tgz

You will see that concretely, the changes aren't so big - they mainly concern the
bitrate
tracking, but that improved picture quality by a lot.

Hi Nic,
to build it as static lib would be great but commandline should be fine. The xbox scene is waiting for such a tool even when it takes a long time on a 700MHz celeron :D
Just my two cents.

[The_Flash]

Glad to hear the new version will be implemented soon. I've been following this project since the beginning, albeit quietly, and am very impressed. Thanks to everyone who dedicates time to the project. I love "gettin' jiggy wid it!"

[Nic]

(The new M2V code is added, but found bugs in the demuxing code while adding it. Taken me until midnight tonight to find it, hence no new build tonight, ill release it tomorrow, but hopefully this will fix problems reported to me with muxing in TMPGEnc in 2-Pass mode and perhaps other problems (IFO-Edit muxing, sync, etc))

[DDogg]

Nic, re the command line interest, I think there is, and there is going to be, a hell of a lot of interest. However, IMO, those type of tool writers are going to tend to wait a while for the construction dust to lay down a bit, which makes sense. I hope you don't take lack of activity at the moment with lack of interest. I figure it is completely disproportionate :)the changes aren't so big - they mainly concern the bitrate tracking, but that improved picture quality by a lot.Quite an understatement.

[jonjon51]

hello all :) , and excuse me in advance for my poor english language...

I bought a DVD burner recently, and I'm very interested in this project. I tested the quality of requant/rejig, and I'm very very impressive with the quality :eek: I requant Pearl Harbor and I can't believed my eyes and time taken to do that !!! so big thanks to Metakine, Nic and the others ;) for this fabulous tool !!!

concerning my post, I'm a very little VB programmer, and I code a Requant Calculator, named Requant Calc ;) , to determine the percentage and the video bitrate (CCE's encoding for example). It may work, but I'm sure it has lot of bugs :p

If someone could test it, it will be very great :)

Requant Calc v0.0.1 (http://easysvcd.free.fr/RequantCalc.zip)

[Mug Funky]

thanks for the tool...

i got a type mismatch when i ran it without specifying any values (except the video file)...

i'm not entirely sure how to use it.

[Nic]

@jonjon51: Nice little tool, what is it actually intended for? Is it to find out the percentage required to fit perfectly on a DVD-R? You could add a button to automatically run ReJig using commandline parameters to start the encode.
I also urge you to release the sourcecode and make it GPL, as I'd like everything to do with ReJig to be GPL if possible. But that is entirely your choice :)

Cheers,
-Nic

[jonjon51]

thanks for the fast replies :)

@Nic: Requant Calc was created to facilitate the research of the percentage of video size reduction. it will be able to have an option for launching Rejig in command line in near future ;).

a small tutorial:
- open the video file
- open the audio files
- open the subtitles
- enter the duration of film in the form h:mm:ss, or directly the duration in seconds
- press "Calculate" button
simple, no ? :cool:

I hope RC will be useful for you. of course, I will release a new version including source code, but I'm a newbie concerning GPL stuff :( . so for instance, I prefer do some tests and improvements before. I'm realy pleased to contribute, even just a little, to this project ;) all your comments, ideas, are the welcomes.

=> new version, without the bug reported by Mug Funky :D
Requant Calc v0.0.2 (http://easysvcd.free.fr/RequantCalc.zip)

[JvD]

Man, I am a Rejigoholic, cant stop using it ;-) Full movie backups toghether with doif4u, Reauthorist and scenarist and movie only with Rejig and Ifoedit works great. The last method needs som cut and paste action of subtitle colors (in ifoedit) and also add celltimes (Or do I really?). I have to calculate bby hand and it doesnt end up so exactly (4200-4400). Still it is more than a one-click-solution (nothing thats bothers me). Looking forward to the new Rejig with the improved picture quality AND a way to automate the whole process. From ripping to authoring. Keep up the good work!

Requant Calc v0.0.2 (http://easysvcd.free.fr/RequantCalc.zip)

@jonjon51
Missing only the possibility to enter the DVD size. I'm a DVD+R user and those discs are smaller then DVD-R discs. Could you add an option to specify the size.

Also usefull if you want to keep space avalilable for some other data.

@Nic
Maybe it is also possible to integrate this in Rejig. So it will be completly automated. Just specify the DVD size and Rejig will calculate based upon selected audio and suptitles what the compression should be.

[Nic]

@DVDRFreak: Still don't own a DVD writer yet ;) (Don't even own a DVD Player yet, ordered one yesterday ;) (used my Duron800 up until now )). So my calculations might not prove fruitful (the problem is the added size that occurs due to muxing, that's the bit im not sure of yet).

@JVD: for the cell times do you use the export function in the latest ReJig? if you click export under the chapters it will create a list (unlike IFOEdit which create a Cell list?? Which is weird, as on a dvd the chapters are chapters, not cells (often get 2+ cells to a chapter)).
What do you have to calculate by hand? Is the 2pass code not very accurate for you? Or is that you have to work out what size you need?
Glad you like it so far :) The release later today should be even better.
(ps. could you also send any IFO files that have failed to be read properly to nic@nic.dnsalias.com )

[jhmac]

@JVD

Could you do a quick guide on using rejig and doitfast4u?

[E-Male]

ok, where to start….

@jonjon51: nice contribution
but like Nic brought up, muxing vobs causes a certain overhead, does your tool take this into account?
@NicBtw I don’t know how to calculate this overhead, but I’m sure it’s possible to a certain extent of precision, I think the length (not size) of the video is the main factor

@JvD&all: for movie-only-backup I do like that:
-rip the video, audio and subs
-do some rough calculations and rejig the video
-then rip the complete vobs to hd (not needed if anydvd or similar is used)
-then use the remux .m2v feature of ifoedit (with strip streams and create new ifos for movie only disc)
(-repeat from the second step if size is not fine)
-burn or create image….
This way there is no need to copy colors and stuff

Can someone please explain to how to use rejig with doitfast4u, reauthorist and scenarist for full movie backups?
THX in advance
EDIT: jhmac posted while i wrote my post, i gues we basicly ask for the same thing

About the upcoming new version: if quality gets even better: WOW!!!
Hope more automation for movie-only and full backups (either in rejig itself or in tools controling rejig) will evolve soon
Can wait for the first full GPL backup tool(s)

To bad I can’t really contribute to the projects
Maybe my little guide helps some people, feel free to ask questions about it

mmgrover is hopefully going to collaborate with Eyes' to do the DoItFast4u work. (I've never used DoItFast4U so mmgrover will the better man for the job). At present DoItFast4U and ReJig probably aren't that viable until an update to both exists (which won't be far away I hope). (feel free to nag Eyes' and mmgrover ;) )

With the next release you'll be able to select the old transcoding algorithm as well as the new one. Just in case the new one has bad side effects.

ReJig will eventually be able to do Movie Only Backups all automated from inside ReJig. DoItFast4U im hoping will be used for the full back ups. But we'll have to see :)

-Nic

[E-Male]

maybe rejig could be split into 2 version

like "rejig basic" for simpel transcoding and movie-only-backups

and "rejig deluxe" with doitfast4u and dvdauthor code included for full-backups with one (GPL) tool

what does everybody think about that, good idea or bad idea?

to make this clear: i both versions should stay free, no freeware and shareware version or stuff like that

[mmgrover]

@E-male
As far as I know, ReJig will always be free?

Yes, ReJig currently works with DoItfast4U, but you would have to
play with percentage to get file size close.

I am currently working with eyes to incorporate the new
file size method of ReJig :-)

I was just dragging my feet a lil to get source code after nic added
new ReQuant engine...


mike

[E-Male]

>As far as I know, ReJig will always be free?

just wanted my post to be understood correctly (someone might have thought i'd recommand a free and a paid version, which is NOT the case)
i just meant 2 version instead of 1 with to different features that might get confusing (and maybe hard to keep track on code-wise, don't know)

looking forward to this better integration.....

[jonjon51]

new version of Requant Calc (including VB sources code ;)):
- you can specify manualy th DVD size
- the "Del" buttons now work perfectly
- you can directly run Rejig after that Requant Calc find the right percentage ;) the 2-pass mode is not yet implemented (@all: does it work fine ?), and it's completely untested (I'm at work now :D)

@E-Male: at the moment, RC doesn't take care about overhead :(. I didn't know that DVD muxing cause that... but I'll think about it :).

Requant Calc v0.0.3 (http://easysvcd.free.fr/RequantCalc.zip)

[E-Male]

hm, found that with a quick google search:
--------------
DoItFast4U:
"Built-in DVDCalc!
Amazingly accurate compared to others out there.
Adjusts for .vob overhead automatically! "
--------------
i gues that means we now know who to ask *g* ...

Requant Calc v0.0.3 (http://easysvcd.free.fr/RequantCalc.zip)

Great. Tested it looks like there is still a problem.


Use Reauthorist to calculate size for my movie only:
4693190210 DVD size

14:50:56 VTS03 PGC01 angle 0 original muxed video size = 6012438537
14:50:56 Calculating size...
14:50:56 Audio+Subs = 387663963
14:50:56 VIDEO_TS = 0
14:50:56 Original muxed video = 6012438537
14:50:56 Initial reduction = 0.716142
14:50:56 Finished auto sizing...
14:50:56 VTS03 (raw: 4595494695) (muxed: 4693190210)
14:50:56 VIDEO_TS Size (0)
14:50:56 Total DVD Size (raw: 4595494695) (muxed: 4693190210) (total: 4693190210)
14:50:56
14:50:56 Encoding list:

"C:\..\VTS03\VTS__03_P01.16~9_1.AVS",0,9352,4947,0,5

This will give me a resulting DVD that almost always fit's on one DVD+R. Compression ratio calculated is 71.6142% CCE bitrate 4947

Used RejigCalc:
Samed DVD size so 4693190210

It gives me a percentage of 72.9% CCE bitrate 4928. Resulting DVD will be to big.
Edit:
To see if I am right I will try muxing later when the new version of Rejig arrives.

Edit2:
Add the CCE bitrates. Which seems to be very odd because the calculated bitrate by RejigCalc is lower the that of Reauthorist.

Missed out 0.4f, went to release it but my ISP was down, so made 0.4g instead with IFOEdit authoring support. Can now automate IFOEdit to author the DVD. Put IFOEdit 0.96 in the same directory as ReJig.exe.
(IFOEdit support just controls IFOEdit, it works on my English Win2000 but may not work on different operating systems...will need feedback to fix)

Also includes the new transcoding algorithm. At present you can't turn it back to the old one, however the old is used when:
1) Using percentage (1-pass) mode from the main dialog, unless you are encoding from a raw .m2v
2) In IFO Mode if using percentage (1 pass) encoding.

In all other cases the new encoding is used.

@Nic

It's great that IfoEdit can now be automated for authoring but like I previously posted, IfoEdit doesn't do too well with NTSC. Here is a past thread (http://forum.doom9.org/showthread.php?threadid=37953) on IfoEdit 0.95 authoring discrepancy. I guess it goes along with what you found too. http://forum.doom9.org/showthread.php?s=&postid=391721. :(

I'm doing Matrix Reloaded R1 right now using my method (http://forum.doom9.org/showthread.php?s=&postid=403103#post403103) I posted earlier and I'll see if I got audio and video sync. If successful then a full backup is possible with everything intact.

[DMagic1]

Funny you say that 2Cool. I was doing the same movie and I used Ifoedit. The result was jerky playback with my pc dvd player. It would not skip to chapters thru the menu or with controls. This was run with Ifoedit dvd player function and WinDVD. I don't know if it was an Ifoedit problem or Rejig yet. I'm about to use your method.

[2COOL]

To all,

If you want to shrink your menus using ReJig, substitute the original menu file with your ReJig's one after renaming and use Menu Extras in IFOedit to correct. Open your IFO in question, do a stripping of your VOB IDs, and KEEP EVERY VOB id. Replace old files with newly created ones and get VTS Sectors. Works for me. ;)

Update: Just got done with Matrix Reloaded with everything kept like original. No audio and video outof sync and it looks great IMHO. :D Thanks to all and I even get to retain my subtitles!:D:D:D

@DMagic1

If you are not using FAT32, decrypt your main movie or titleset vobs to a single VOB. I used DVD Decrypter with no splitting in file mode. This way you can get ReJig's m2v to remux in one session using VOBedit. You don't have to join cells using VOBedit, just rename the vobs accordingly and create new IFOs for them.

[daddy_fizz]

so can you use ifoedit to do full back up (not just main movie) if so i don't suppose you want to do a step by step 2cool :D

am i insane, or is that latest download rejig 0.3b?

~Fizz When I did Matrix Reloaded, I had used ReJig 0.4d. I'll see what I can do after trying the movie again using 0.4g. The only problem I can get is trying to calculate accurate sizes so that my remux titleset is where it supposed to be. This goes for eveything else like menus and other titlesets. I just need a big picture on the whole DVD on what sizes I can set them to. Other than that, my method seem to work. I'm 3-0 now. Though I used IFOedit in my small guide, the big player is VOBedit in the remuxing department.

seems to work now. strangeness.

hmm... i seem to have found a little bug.
http://www.sharemation.com/mugfunky/hideki.jpg

what do you suppose those interlacy blocks are?

some stats - Chobits v3, R1, NTSC (of course:(), and i think this bit is IVTC, but the intro alternates quite a bit so i'm not concrete about that. it may be interlaced.

oh, yeah. rejig settings - put the vob file in (not ifo mode) and set it to flat 1-pass 50% recompress.

tried it in 2-pass mode (filesize set to 50% of the original) and it worked fine.

[daddy_fizz]

wierd...

just tryed matrix reloaded

if i play it in powerdvd, perfectly smooth, if i play it in zoomplayer, playback is very choppy.

quality is good, and fits very well to dvd!!! just about every last mb used :D

also for some reason even though i authored with i can not turn them on in powerdvd...???

Turn what on? subtitles?
if i play it in powerdvd, perfectly smooth, if i play it in zoomplayer, playback is very choppyI tried with Zoom Player Porfessional 3.20 final and I didn't see any choppiness.

[2COOL]

Update: Just did Matrix Reloaded again with ReJig 0.4g doing my single combined movie vob at 2pass @ 3000MB. Total DVD size on DVDR is at 4.32 GB (4,644,859,904 bytes). Looks awesome to me! Sweeeet!:D:D Kept everything, even the Warner Bros intro logo and FBI warnings. Again, I have my subtitles.:D Imagine if I stripped out all unwanted stuff like even French 6ch audio. The video quality would be even better.

Hmmm...maybe I'll do a LoTR movie next.

[daddy_fizz]

yes subtitles, cannot turn them on in powerdvd,if i use zoomplayer then i can see them flash but they are a green color and look fuzzy...

Would you please do up a guide for us newbies?

[bb]

This thread is now 25 pages long :eek: . What do you think about opening a new thread for every major new version? Imagine someone searches for a ReJig topic, and sure he'll find... this thread! So he's still got up to 25 pages to browse until he finds the part he's interested in.

bb

[JvD]

OK, havent been able to try the new version yet but I do have som qustions and answers.

Nic: When I make my full-movie-backups (dif4u, Rejig, Reauthorist and Scenarist) and load rejigdata in Rejig, there are calculated % for each videofile in the 1-pass-window. But the 2-pass option isnt calculated for me. It says 0 (atleast in 0.4e). NIC, this is what I mean "calculate by hand". Is this corrected or did I miss something (as usual ;-)

Eyes (and Nic): there would be better that DIF4U use the 2-pass-option as standard instead of 1-pass as it is now. Since DIF4U can autorun Rejig this would be a great option that the % number for 2-pass also is put into the MB-field. Is this a bug or has it allready ben taken care of. (or is it ME AGAIN!)

Nic (and others): In the new version 0.4g there is a possibility to tell IFOedit to author the movie for me. Since I am still at work I havent tried this feature yet (eager to get home) I am curious about this. Can ReJig do a full-movie-backup in this way or do i have to take one PGC at the time, as before? Since i think IFOedit is faster and FREE it IS a better alternative than Scenarist.

bb, dont you think there is a point in only having one thread, read Nics ReadMe.txt. But for a new guy, yeas it could be hard to read trough the full thread. But then again, it is good reading and you can learn alot. For those that been around since the start i find this 25 pages tread OK. If thera are one new thread for each new version ther will be alot of ReJig threads, dont you think. And you have to remember in which thread you last posted you qustion or answer, and so on. There could be a sticky witch updated with every new version and release notes, what is new and what is fixed. And people who have specific qustions about ReJig can start new threads to get ansvers, BUT the development of Rejig suits well in this format. But then again, thats just my thoughts ;-)

[Nic]

By Full Movie I assume you mean Full DVD type backups (i.e. all the extras).
The current ReJig and DoItFast4U will be changed by mmgrover and Eyes' I hope, to work better with each other. I hope that will happen soon and leave it to them.

IFOEdit is only used currently to make movie only back ups at present.

I think when DoItFast4U support is added properly and the last bugs in the current version have been removed. Then Ill start a new thread and collaborate with people to write a few guides. So people that have been over awed by the size of this thread can start a fresh.

-Nic

[ffroms]

Hi to all !!!!
I'm reading these thread for sometime now (even have direct link in my Favorites) and I'm realy amazed how fast and good ReJig works.
Now, I have a little question. Will it be possible (in some future version) ReJig video but to use diffrent compression level for diffrent part of same movie?
For example:
If I use IFO mode and set 2 pass to 4000MB and then define for end credits to use only 30%, for action part to use 100%, for slow part 60% and so on.
This option will be much better for achieving the best possible picture for movie. I know that something like this can be done by spliting vobs to cells but that is to much work. There is something like that in DVDShrink but I would love to do all my work using ReJig.
BTW, is it OK now to use ReJig for menu part?
Thanks again to all for hard work.

FFS

P.S. IfoEdit do have problems with authoring NTSC DVD so maybe it would be better to use some other (free) program for authoring (although I use ifoedit for everything besides authoring).

[E-Male]

on a good dvd te bitrate already is distrubuted well
and rejig just keeps this distribution

[mmgrover]

@Nic


I added rejig to web site :-)
I am working on making changes to code for DoItFast4U right now :-)

mike

[E-Male]

just for my curiousity:
has anyone of you programmer looked into that gpl authoring tool(s)??

[Nic]

@E-Male: Yup, lots. Main problem is a viable clean way of getting subtitles into vobs. Ill keep you posted on developments...

[E-Male]

thx for the info

i'm i right when i think that this is the last missing part for a complete gpl dvd-backup tool?

[jdobbs]

I would think that with subtitles all you need to do is keep them intact from the original source (packetized) and remerge them into the output stream at the proper time based upon the SCR. That way you could save all that time (in some methods) pulling them out and recreating them. Anybody know a reason why that can't be done?

[Nic]

@jdobbs: Thats what im looking into, I don't know of any code existing that's capable of doing it. I've asked Andrew Steven's of the mplex project his opinion on the matter. It's very doable, it's just a matter of writing the code in the best way.

@E-Male: Yup that would make it all GPL. Seeing that IFOEdit contains GPL code in the Authoring section, I was hoping Derrow would release at least that part under GPL. But to no avail as yet.

-Nic

[jdobbs]

@nic,

I'm currently working on something similar. It's aimed at remerging CCE output into the original stream. I'll hack it and test it later today and see if the captions appear properly.
