GOP ERROR

[msb-mike]

After reading a post on AfterDark, I have been encoding and burning BIN/CUE files by doing the following:
1 Extracting the MPEG files with IsoBuster
2 Encoding with MainConcepts MPEG ENcoder
3 Merging files with TMPGEnc
4 Authoring with TMPGEnc DVD Author
5 Nero to burn
A few days ago i read a post on VideoHelp informing me i could skip step 2, the MPEG files do not need to be encoded, they can be authored and burned. I tried skipping 2 and received an error from DVD Author informing me the GOP was too high (25fps PAL), and if i countiued authoring the DVD would not be in format.
What should i do?

Hi msb-mike,

I'll share something with you that I learnt today...

Based on that, I'd say you can skip step 2 and fix your GOPs. Of course, you can still re-encode, but that reduces quality.

See the "Glossary" (top left of the page) for what a GOP is).

I wouldnt worry about the gop error tda gives,just choose ignore and go ahead and author,i ignore that message any time it comes up and never have a problem playing these dvd`s on at least 2 different dvd players,(apex1500 and nexxtech).

...didn't find the guide.

What guide? The link I posted was referring to a tool, MPEG-VCR, that will fix your GOP error.

Have a good'un yourself!

You cant fix gop frames that are too high,just gop sequence headers.

You cant fix gop frames that are too high,just gop sequence headers.

It will fix cases where you have got the Max number of frames in a GOP setting set to 0 (No limitation) also.

I've used it on a file with these settings:



... and it fixed that OK. I don't know how or what it did, but I didn't get the GOP error message in TDA after that.

Sounds good,i was always told gops set too high needed to be re-encoded,i`ll try it out,thanks for the tip.

Tried womble to fix gop too high and it does re-encode the mpg and adds frames which introduce artifacts,rather just ignore the warning message.
