Error: GOP is too big

[Jaffa]

Ive joined 2 mpg files but when i try to add it into tempg author to make a dvd it says the GOP is too big.

Wot am i doin wrong, please help.

Your GOP is too big.

[dafreak]

lol
nice answer smurf.


@Jaffa
check the GOP structure in your encoder. GOP can't be more than 18 for ntsc and no more than 15 for PAL.

I've never tried it but Womble MPEG VCR can supposedly fix GOP errors.

It could be worse. All the complaints about me involve
being too small.

A couple times I've made a DVD with TMPGEnc DVD Author, then later opened that DVD with DVD Author and had it convert the files back to mpg. Twice, when I loaded the mpg back into DVD Author I got GOP too big error.

The first time I just ignored it and the end result still played fine on both my computer and standalone. The 2nd time I ran the mpeg file through TMPGEnc's merge and cut and it fixed the problem. Since I haven't had any trouble with the disk where I ignored the problem, I don't know if it's worth the time to fix it that way, but it probably is since it only took a few minutes.

Really helpful guys

It is an unfortunate fact that an mpg made by one program is not the same as an mpg made by another. I have gotten the GOP too big error as well as sync errors when editing an mpg with another program before putting it into Tmpgenc DVD Author.

If you want the video to play smoothly at the join then use womble mpg vcr. It makes a seemless join and works great with Tmpgenc DVD Author. There is a 30 day trial.

If you don't mind a (slight) pause at the join then just keep them separate and put them one after each other as two chapters in Tmpgenc DVD Author.

Hi,

I also use TMPG DVD author. Whenever I get a message like that, I drop that same MPG into ULEAD DVD Movie Factory 3 and it takes it without any problems.

I don’t see why you are joining the MPGs prior to dropping in the DVD authoring software, you might as well put each in separately.

I had this error the other day and ran it through TMPGEnc and in "settings' I changed the GOP to 15 (PAL) and it worked. TDA will actually tell you what the GOP should be.

[Jaffa]

Where did u change the setting to pal 15??

Jaffa,

MPEG files can`t be cut elsewhere, ideally, you could just cut it at the GOP border,

Of course cutting sw`s allow you to cut it wherever you want, and also join them wherever you want, so.......as it`s very very unlikly you`d cut randomly at the GOP border..... :P

Two choices :

1) Reencode the file and loose quality;

2) Use Ulead cause it`s authoring sw`s seem to do not check GOP length...

3) Try to fix just the GOP`s without reencoding. DVD Maestro joins two files without reencoding and fix GOP`s, Womble is supposed to do that as well, I`ve tried it twice, no luck;
