video sequence header problem ? (making mpg files to dvd)

[camus]

I cant make my mpg files into dvd files i use tmpgenc dvd author
it says:a video sequence problem is necessary for every gob in a standard dvd ??
what do I do ????

Hi camus,

Are you using TMPGEnc to encode? If not, what are you using? Are you encoding at all or do you already have MPEG2 DVD compliant files?

As you're using TMPGEnc DVD Author, I'm gonna assume you're encoding and using TMPGEnc.

Before encoding, click: Setting (bottom right) -> GOP structure tab -> Set "Output interval of sequence header" to 1.

If you're not encoding, then MPEG Sequence Maker sounds like it will do the job for you.

Hope that helps. Good luck...

I'll second that, I have used mpeg sequence maker to fix exactly that error. Just de-mux use the program to output a fixed file with a different name (IE file.m2v in and file-Out.m2v for the output) and add the video and audio streams to DVD Author. It'll take them muxed or separate so why spend the time re-muxing them.

Good Luck

I have never gotten MPEG Sequence Maker to work with anything but MPEG1 video files. Makes a mess of M2V files.

May need to re-encode.

Use tmpgenc mpeg tools/merge and cut and save,works for me all the time.

Womble MPEG VCR (or Video Wizard) has a nifty utility that fixes GOPs etc (its in Womble> TOOLS tab > GOP FIXER).

A time limited download is available.

I'll vote for this too. Works well.

Glad it worked for you, It never fixed a sequence header error for me.

A file that gives that error when run through Womble can check out with no errors, As near as I can tell it checks for three things, but a video sequence problem doesn't seem to be one of them. I haven't tried VideoRedo yet. It seem to be reccommended on another forum for fixing problems with Mpegs where the sync gets out gradually. According to Dan Rosen from Video redo the problem is that in the Dish 50x rips there are problems with the stream. But I digress. Next time I see this particular error I'll download the trial and give it a try. Unless someone beats me to it of course

I tried mpeg video gop fixer
I put it in input and it fix
but it doesnt work
shall i put something in output cos that is blank ?

[monzie]

Oh dear...

Yes you MUST select a location to SAVE the file and a NAME for the new file as it doesn't touch the original.....(I just add GOP to the filename to remind me its been fixed...eg..homevideo.mpg > homevideoGOP.mpg).

The process only takes a couple of minutes.

HTH

[camus]

thank you it works
but when i come it into tmpgenc dvd it says when i come videoclip 2 in
that the video resolution 325X240 is not compatible with the current track
and the videoframerate is not compatible ???????

[camus]

forget about the last post

mpeg-vcr works with some of the files I ALSO TRIED WITH
mpegsequencemaker but the file is not a mpeg1 file and then it wont take it ?????

@ camus - I'm guessing from the problems you've listed (no sequence header, non-standard resolution, (seemingly) non-standard framerate) that these are downloaded MPEGs?

If you're gonna download MPEGs then you're at the mercy of an unknown individual doing the encoding and there's a good chance that you're always going to run into these problems, or others of some sort.

So, get good at identifying them and sorting them...

Just to add to that, the MPEG-VCR route will only fix the GOP error. If you've got non-standard resolutions and/or framerates, most likely you will need to re-encode, and if you need to re-encode, you can fix the GOP error there and then during that process, so if you do need to re-encode, don't bother using MPEG-VCR to fix the GOP error (it's a redundant step). Only use it if you your file is DVD-compliant in all aspects bar the GOP structure. There's only about 2848568 guides on this site that walk you through how to re-encode, and about 3 times that many posts in the Newbie/General Discussion and/or Newbie Conversion forums.

I'd recommend this guide for low-res, low-quality MPEGs that you wish to put on 1 CD (your player must be able to play raw MPEG or XVCDs though), or this guide if you wish to put it to DVD. Either of those guides can do what you need to do.

I've tried fixing satellite 544x480 mpgs with mpeg2vcr and even though it fixes the gop it makes it out of sync by a few milliseconds. Has anyone else came across this problem as well? thanks

[Soopafresh]

Try PVAstrumento. It is pretty good.

[nick101181]

I tried pvastrumento as well cause someone told it it fixes the gop when it demuxs the file. It didn't fix the gop at all. I tried the tmpgenc encoder trick to save as program vbr and it was out of sync. I use mytheatre to record but I have to use version 3.12 because it's more stable for recording. I used version 3.19 one time and it has a option that records it compatible for dvd but ever since I been trying different version, I can't install it the same way again. I got no idea how I did it to keep it from messing up the recordings after 30 mins.

Try the Beta of Videoredo, It's Quckstream Fix is supposed to work with Dishnetworks streams with respect to fixing sound going out of sync. It has a 21 day trial and Dan R from their was helpfull with support even though I was running in the trial period, That is what I call support!

Cheers

[nick101181]

thanks tbone. I tried it with every option availlable and the end result was out of sync as well.

[TBoneit]

Did you try the beta version? http://www.videoredo.net/beta/
and then go to tools "Quckstream Fix" ?

Don't try the 311 version, There should a new with a problem fixed version saturday (per Dan R)

Good Luck

I think I've found out what the problem is now I need some help determining a solution. I tried a 945 mb file in womble mpeg2vcr and it fixed the gop and the audio was in sync. I then tried a 4.59 gig mpeg2 dvb file and the end result was out of sync big time. This tells me it's because it's dealing with a file that's too long. What could I do to fix this so I can correct the gops on this and other large files that I have? Can I split them up into 900 meg chunks and feed each 900 mb chunk into mpeg2vcr then rejoin them, or would this cause it to be incompatible as well? any ideas?

[TBoneit]

Nick, have you visited the Yahoo Dishrip group if your source is DishNetwork... It sound like their resolution to me.

It isn't the file size, trust me on that.

If so then the Beta version of Videoredo using Quickstream Fix will fix the sync problem.

Most people ripping from the 50x series of DVRs have a sync problem that Videoredo cures. If I do a 7100 with different software using the keep audio sync option then usually it is ok. But that s/w only works on 7100 & 7200 models.

As I understand it the sync problem has to do with the way the Mpeg stream is done. (Non-std).

You can also do edits and gop size fixing in Videoredo as well as open a .ts format file and save a Mpeg or seperate A/V streams.

Good Luck

[nick101181]

well I finally figured it out. I tried tpmgenc mpeg editor and just loaded and outputted the file and it's now the gop is fine and the whole file is in sync. I dunno why but videoredo either cut out a lot of frames cause the vid was skipping chunks or it was not in sync for me. thanks tbone
