Heres a tip (DVB ->DVD) w/o encoding.

[likwid8]

After carefully examining this I took into consideration the following error. I'm pretty sure most of you have basic knowledge of this already but I'd like to stand out and state the obvious.

Basically, when capturing a digital stream using a PCI card which uses DVB encryption, there tends to be a 3 streams in the .mpg file. As you all know you have the video stream, which captures at about 544*480 or 740*480, with bitrate reaching up to 8000 mbit/sec, you gotthe audio stream which consists of 48000 K/hrtz of audio with a bitrate of 224k/sec. And last but not least we got this annoying "private stream". Well this is where it gets really tricky. Once you capture your footage and you decide to cut it, that edited (cut copy) becomes nearly impossible to reverse to its original state. In other words, you will be getting sync issues, video lag, and fuzzy lines diagnally across the video when there is fast motion.

After long and serious testing I came to the conclusion that the best way to avoid that is 2 of the following;
(a)- you capture what you want to burn/encode from start to finish
(b)- you capture and if needs edit you will need to demultiplex and remultiplex using specific programs aswell as authoring.

When I have a PPV coming up, i usually press "record" right when the warning screen comes up, and then usually around the end Id like to stop the recording exactly when it goes black, because if i go over, ill need to spend roughly 3 hours trying to fix the problem depending on what you really want to keep.

Now heres the tip: (programs I've chosen as my strategy)

===========================================
First off capture what you want to edit/encode, then when your done with the capture and you saw you want to crop out the first 30 seconds of the footage because its irrelivent to what you want to burn, you need to the following; (WARNING: not doing this might cause serious stress and may lead to symptons of stress and aggrevation)...

First you get MPEG2CUT, and you select the footage that you want to keep. you then open the file in Project-x and demultiplex the file into a m1v and mpa(mp2). You then load the video and audio separately into TMPGEnc DVD Author and ignore the GOP length and author thats it..... the original file (740*480) has all the DVD compatibility it needs to be authored, in terms of video resolution and bitrate and audio bitrate. Thats for DVD but if you would like to encode it to a VCD or SVCD I suggest you use DVD2AVI and you save the project as a .d2v file and you load that into your tmpgenc or cce or preferance encoder along with your mp2 and encode to your desire. QUICK NOTE: load the direct m1v file into tmpgenc might give you an error as the file has been edited and revised from the original file. If your having problems with DVD2AVI just load the mv1 into VirtualDub-MPEG2 and framserv to TMPGENC. But i suggest you compress the file into an .avi using virtualdub and then loading the avi into tmpgenc. Im throwing various ideas (tips) here to help you get the most out of your footage. One last more resort would be loading the .d2v file in VPAFI plugin, framserv to an avi file then loading the avi in encoder and itll work. After that you got your own video.


But like i said, you can avoid all that but just capturing what you want, that way the original file wont have errors. You must be thinking why not just load the original file in encoder and edit from encoder? well you can, but the idea of this whole thing is for DVD, Since most of my caps extend the 4.37 gig margin, i have no choice but to cut the file,and therefore no applications will recognize the video file for encoding/authoring. If your planning on encoding vcd/svcd then ya not a problem but for DVDs that extend the 4.37 margin your in for a hell of a ride. So basically by doing this (takes alot of processing time).

CONCLUSION:
-----------------------
UNTOUCHED VIDEO, with direct authoring. = no more encoding

saves you at least 8+ hours worth per disk. But please note that you might come across 2+ disks for shows/events that output high amounts of bitrate per second. A live PPV may well over exceed its 28meg/min margin so ur gonna get about 7800k bitrate and itll be about 46 min per DVD (thats without creating MENUS)... But i simply love it and I dont think anyone should care because DVD disks are cheap and 2 DISKS for a 4 hour event at 28megs/min aint too bad. DIRECT quality, UNTOUCHED video and sound.... Only prob is most dvd authoring program might give you the GOP structure is too long which might cause you to think its an incompatible DVD, but surely enough Iv tested it in well over 5 dvd players and they work. Make sure it supports DVD-+R (LOOLLL)... Anyways any questions reply thanks.

First you get MPEG2CUT, and you select the footage that you want to keep. you then open the file in Project-x and demultiplex the file into a m1v and mpa(mp2). You then load the video and audio separately into TMPGEnc DVD Author

what? you load the captured file into project x, THEN use Mpeg2Schnitt to edit out adds and select what you want.

Project x will fix any errors associated with the mpg transport stream, ie it will fix the errors caused by poor reception. These errors cause a/v sync errors, which is why you MUST run it through project x. In 12 months of capturing and authoring to dvd digital tv recordings, I have NEVER had a recoding go out of sync, why? Because I have demuxed with project x. IT REMOVES ALL PROBLEMS. You should probobly go to the doom9 guide and read it's contents before posting such utter crap.

Note, that this method, does NOT re-encode the capture.

When you said that if you exceed "the 4.37 margin your in for a hell of a ride." Bull. Cut the properly demuxed recoding with Mpeg2Schnitt, and then author the two seperate disks. Or you could author the full recoding to a folder on your hd, then use DVD Shrink to output you a fully complyent dvd.

Finally my conclusion:
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt


Can't stress this enough!

[likwid8]

DUDE!...

Project X does fix errors, but it will not fix the or delete the private stream which it has.... and when you mentioned you been capturing for 12 months? Well capturing what? using a capture card? Or a PCI DVB card that captures the satellite signal which causes it to have a private stream?

My whole idea to this was to solve the issue of the edited footage. Were not dealing here with just any source, this source isnt the one you been capturing for 12 months, and it certainly isnt a damn tv cap. Its s SATELLITE cap via DVB not no ordinary cap card. And as for using the DVD Shrink? Idiot...... that program does re-encode the video, thats what DVD Shrink does, "shrinks" it (encodes it) to its DVD standard size using crappy CBR.


P.S. Dont tell me you read doom9 because your the one using DVD Shrink as your source for recompression. Sorry to say this but your under the wrong influence thinking your going to come in here and teach me what I said wrong.... Go buy a PCI DVB card, capture a 1 minute of a Satellite stream, cut it to 30 seconds and try fiddling with that, youll see the only solution will be mine.... Not your crappy Analogue caps... pffft

[minchjp]

OK fair enough, should have said, my cap source is DVB card.


2nd pt. Your entire post was to minimize complications. Converting a 7-8mb/s stream to a 6.5 - 6mb/s stream is easy with DVD Shrink, and personaly I can't tell the diference between the "crappy cbr," because DVB is send as CBR data (strict CBR), at least DVD Shrink will use a slightly higher bitrate during the scenes where a higher bitrate is needed.

Alright, I captured a 5min clip from my DVB card, played the file back =>in sync. Used mpgcut =>LOST SYNC!

Used the same source, and ran it through projectx and Mpeg2Schnitt to break into 30 second chunks, perfect sync the whole time! WOW

Finally I figured you might be living in an area with inadequete reception to alow for flawless capture, so i did the following:

half way through my next 5min cap, I pulled the cable out of the card! then i Put it back half way, which caused the picture to break up every 15secs. Ran it through projectx and it removed any sync issues I had with running it through MPEG2CUT.

Finally, we are in a DVB forum, which is preaty self explanitory.

Finally my conclusion:
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt
Use project x BEFORE Mpeg2Schnitt

Can't stress this enough!

I totally agree with that.
After trying different programs and methods to process recorded DVB transport streams from satellite this is the best method for me too.

Dont you have to author the mpeg in order to reauthor it (encode it) using DVD Shrink? since the program only allows DVD folders to be opened? wouldnt that defeat the whole purpose of authoring it if you have to author it in the first place? Why not do it right the first time lol.

When you said that if you exceed "the 4.37 margin your in for a hell of a ride." Bull. Cut the properly demuxed recoding with Mpeg2Schnitt, and then author the two seperate disks. Or you could author the full recoding to a folder on your hd, then use DVD Shrink to output you a fully complyent dvd.

Hmmm.... Author the full recording? Name me 1 program out there that will author a full recording thats over 4.37 gigs? They will give you an error saying it cannot author a DVD which is over the 4.37 limit... and if your going to give me the cheap "choose the dual layer" option then save it, cause what if the raw footage is over 9 gigs?. Point is, there is no way of actually authoring the complete footage since the program wont let you author it if its over 4.37 gigs.

P.S. The DVD Shrink idea isnt that bad now that I think about it, but you do run into that problem.

[minchjp]

Hmmm.... Author the full recording? Name me 1 program out there that will author a full recording thats over 4.37 gigs?

I haven't had any problems authoring with DVDlab. I find also IFOEdit is the easiest option if you are authoring single episodes, you can just load the folders into DVD Shrink, and compile them into one dvd while re-encoding.

I find that with using DVDLab, you can make your full dvd with chapters and menus, author it to a folder on the hard drive, then use dvd shrink to reduce it below the 4.37g point.

what if the raw footage is over 9 gigs?.

Have you ever recorded a file which is bigger that 9gigs? Even my hdtv recordings don't get that big, and i would never author a hdtv file to a dvd anyway! The highest bitrate on an sdtv channel here is 7mb/s, so 9 gigs would give me nearly 3 hours! I think the most I ever put on a dvd was a 1:40 min program.

With a long movie, you would have to split the recording into two parts if you wanted to retain a sensible bitrate!

My point is that it would be rare to find a 3 hour program to record, and at the same time not want to split the file to save the bitrate. So yes, just tell the dvd program that you want to author a duel layer dvd!

I know nothingt about DVB, but you need to be put right on something.

And as for using the DVD Shrink? Idiot...... that program does re-encode the video, thats what DVD Shrink does, "shrinks" it (encodes it) to its DVD standard size using crappy CBR.

DVD-shrink does not en-code, it trans-codes.
The difference? An encoder will take the source file, decode it to raw frames (as if it were being displayed) and then use these as the input to its encoding engine. A 'transcoder' does not 1st decode the source, it simply removes data from the encoded stream in such a way as to leave it legal (within standards) but reduce the overall size. Transcoders tend to work much quicker than encoders, but they cannot convert from one format to another (e.g divx to mpeg). They also tend to produce lower quality output for a given source and filesize than a dedicated encoder, though this depends largley on how much size reduction takes place.

Hmmm.... Author the full recording? Name me 1 program out there that will author a full recording thats over 4.37 gigs?

TmpGenc DVD Author and DVD-Lab to name but two.

[likwid8]

Well I did record WrestleMania about 2 weeks ago, was 3.5 hours long if im not mistaken, it was about over 9 gigs.

As for the TMPGEnc DVD Author, I dont think it will support the 9 gig mpeg file sorry. And yes you are right bout transcoding and not encoding, but my point to it was that it reduces quality. I wasnt trying to be smart. just point forward.

[bugster]

As for the TMPGEnc DVD Author, I dont think it will support the 9 gig mpeg file sorry.

TDA will support mpegs up to DVD-9 size. Can't remember the exact figure, but it is a little under 9Gigs. This is to allow authoring of DL DVd's. DVD-Lab has the same limit, as does any other authoring program that supports DL. So if your source file is bigger than this, you need to reduce it in size. You could always try re-jig, though I can't say if it works with DVB streams.

The best program i've found for DVB Streams is Mpeg2Schnitt

Mpeg2Schnitt is a cutter AFAIK, Re-jig is a transcoder that works on mpeg-2 streams, not DVD-Video. SO you can reduce the size of your video without re-encoding or removing material (assuming thats what you want/need)

[minchjp]

I thought you ment bigger that 9gigs, where you would use Mpeg2Schnitt to cut the file in half and then put in on two dvds
