scene change
 
I am using 2.58, but I noticed when check or uncheck the detect scene change...
It does it for all the templates regardless of what you had checked when you saved the template...

So once you uncheck the scene change all templates will use that setting...

at least for TmpgEnc 2.58

Hi KingTuk,

Can you try something. Uncheck it, and then load any KVCD template. You should see it unchecked.

check / uncheck
 
yes that option stays unchecked or checked once you set it...
no matter which template you use...

But the problem is for new people installing TmpgEnc is that it is checked by default...

So the first time you use TmpgEnc with any of the templates you need to uncheck it and then it will stay unchecked...

Why do we uncheck "Detect Scene Change" ?

"Crap threat" heheheh. What, like "Put the money in the bag or I'll repaint your living room!"? :mrgreen:

Detect Scene Change inspects the material as it encodes it and, if it thinks a frame is dissimilar enough from the previous one, will insert an I-frame at that point. While TMPGEnc usually gets it right, for a long movie there might be many frames it thought were scene changes but in fact weren't.

This leads to more I-frames than is necessary, and since I frames are much bigger than P- or B-frames (10-20kb instead of 2-8kb) this makes for a bigger resulting encode.

The positive side of Detect Scene Change is that it theoretically results in higher quality, but the size trade-off probably isn't worth it.

It also makes prediction harder, since TMPGEnc won't necessarily use a whole GOP to encode each sample but will instead insert new I-frames here and there. This could throw off the prediction by quite a lot.

the cd technology is changing soon we may be able to get about six hours of video using lbr on the same cds we are using now
http://www.digital-sanyo.com/BURN-Proof/HD-BURN/ but the problems with the technology are that they arent read by cd-rom drives but are read by a dvd-rom drive with a firmware update but i would have to update my dvd player with a new firmware or have to buy a new dvd player to play this hopefully it will catch on it looks very promising to get 4 hours using all other templates or if u must 30 minutes of dvd standard video i hope u like this it looks good
