Finding out the correct chapter points after encoding

[wicked2000]

i have a little problem ...

i recoded a movie...on the dvd there are lottsa trailers and bonus movies i wanna keep ...

so i re encoded them with a lower bitrate so all can fit next to the main movie on the dvdr ...

when i muxed them back and tried a testrun with power dvd xp (playback from hdd) they will play too long cause the chapterponts arent correct anymore

i kept the original IFO file and just put the new VOB file (with recompressed video and original ac3 sound) into the VIDEO_TS folder

the chapter points have changed cause the recompression altered the GOP structure and the I-FRAMES have moved


the movies dont seem to end but after a long time the screen being black the next movie is played

example: TRISTAR COLUMBIA Trailer.... wait...wait..wait ... FBI warning ....wait...wait...wait... another warning....wait....wait ...wait ...main menu

and so on

now my question:

can someone tell me how i find out the correct endpoints for the movies after they have been compressed? and how can i put those new framepositions into the IFO ?

thanx!

You can't just put your reauthored VOB file into the VIDEO_TS folder and expect things to work most of the time- you have altered the original IFO structure. You need something like IFOUpdate to 'fix' what you broke. Do a search, and start reading all about IFOUpdate. The forum is filled to the brim with information about this.

as u read i didnt just expect it to work cause i know what the recompression did

The chapter points have changed cause the recompression altered the GOP structure and the I-FRAMES have moved

this edited the video stream and not the ifo... i wrote i took the original IFO..and not a re authored one ...

i know that i have to use ifo update ...and i know how to use it

my question is:

how do i find out the new chapter points ...


the forum is NOT filled with that sort of problem ...

thats what ifoupdate does i think
reads original and the new authored ones and makes corrections

You probably need to reread some of the threads regarding IFOUpdate.

whuts ya problem man?

i tried ifo update and it didnt work for my problem ... i read through all the ifo update guides and used the search function of this board ...

i am not posting this message for u to tell me to use the guides or look in the forum ...

maybe u just dont understand my problem ...

First of all, you didn't describe what process you used. You didn't indicate you used IFOUpdate, nor did you indicate how you "recompressed" the VOBs.

Typical process when using IFOUpdate (ignoring some of the somewhat more complex arrangements):

1) Use DVD2AVI to demux entire VOB structure (except VOB_0) as a single d2v.

2) Fire up IFOUpdate and have it save CCE and Maestro chapter points for this particular VOB.

3) Use SubRip to rip the Subtitles you wish to include.

3) Use AviSynth and CCE to re-encode video. Make sure to either import or create Chapter Points in CCE. Use points produced above in Step 2.

4) Do pulldown on encoded video.

5) Import video, audio, and chapter list provided in step 2 into Maestro and reauthor Video.

6) Do pulldown_drop_frame, import into Maestro. Now import subtitles.

7) Compile within Maestro, and rename resultant vob to the original (Output is always named 'Vob1', may need it to be 2,3,4,5, etc)

6) Copy newly prepared VOBS to staging area, along with original IFO file.

7) Run IFOUpdate again, and 'fix' the IFO.

guess what...

this all didnt work ... i tried all this before...then posted in this forum ...

Wicked,

What Calypso explained should work (at least it does here).Are you sure you really watched each step carefully ?

On another note, I doubt words like "whuts ya problem man? " will bring you much help here...
If you can't stand being told to read the guides and search the forum, you will miss a lot of valuable information. Now I can understand you get frustrated not finding the solution to your problem fast enough, but these things take time and sometimes require several readings and cross-readings to be mastered. Some people(including myself) used to think "I've read it all so don't bother" but it appears re-reading allows you to understand some details that take more sense than at first time and help put all the pieces together. After all, this is not easy stuff we are dealing with here.

Sorry I can't help you more than Calypso already did, hope you'll find the answer.

ok i must apologize for using word i didnt want to use ... i felt nerved caused calypso was hunting me through the board and commenting my posts in other parts of this board ...

as u said this all is not easy here and i solved my problem another way ...

the guide calpyso gave me didnt work on my problem though it may work on other movies or dvds ...

i had to experiment a little bit and use other tools than those mentioned.

believe me...i tried it like described from calypso ...

i had the feeling he thought i was too dumb to do that so he posted again and again ... telling me what to do.

i was nerved so i asked what the problem is ...

i will apologize calypso but i want you to understand that your description wasnt the 100 % solution and didnt work here on my dvd ...

i dont wanna argue around ... thats childish in my opinion...so lets shake hands and keep the peace, ok ?

Wicked2000, no big deal, you are wise enough it seems.

Happy to see you found your solution.May I ask how you did (might help me too some day :)

1. use doitfast4u to demux the audio/video from the vob
2. recompress the movie in CCE by adding the *.avs script
3. open the movie to see how long it is
4. create a celltimes.txt by adding a 0 and in the next line the ending frame of your video + a number of your choice

example: the movie is 401 frames long then your celltimes.txt looks like this

-----------
0
4010

-----------

u have to do this cause ifoedit swallows the last digit (dunno why)
5. now open ifoedit and load newly authored video, audio and celltimes.txt and author a new VOB
6. now use ifoupdate load the original IFO the newly authored and FIX it ...


until i succeeded with this method i had tried several others including the one by calypso

BTW: with this method i dont have to use expensive programs like maestro ... freeware is good enough :)

[waldok]

I'll have to try this, although I don't understand why IfoEdit would eat the last digit (but who cares since it woks ok like this).

thanks for the interesting tip

[wicked2000]

cce is available as a demo version with a logo in the videos ...
