I have encoded three or four movies with CCE till now and i must say that i was just thinking last night when i watched my LOTR that i had squeezed on to one DVD-R that the quality is still not what i really want it to be............i squeezed LOTR with CCE and it turned out fine (i squeezed it with CCE 2.50) ..except ..only at the moments in the film when its dark i get artifacts/macroblocks or lets say that you can see the artifacts/macroblocks better when you increase the contrast on your tv.....

first i did a one pass (the guide getting CCE way with the normal settings)....and during my second pass i used 5 times vbr ..with a max of 9800 a Bias of 0 and the highest possible average kbits ..i cannot remember but i guess it was around 2750 or 3000 because of the fact that the movie is so long .....so is there any other way to make sure that the artifacts dont happen in films with black background or films with low light and/or are taken in night time and stuff....

should i have also set a higher min or something??? I thought that with setting a higher average global bitrate it would have been better quality.....also i watched my movie on tv with my rca out of my video card on my pc .......

so a couple of questions to everyone:

1: is it usually better quality when you play your finished DVD-Rs with a standalone player since its hardware de-encoding instead of software de-encoding with Power DVD???

2: does it change per TV ..maybe because of the fact that my TV is very old i have to increase the contrast light setting on my TV to see things better....this is also for normal broadcasted things ....its usually to dark other wise....and naturally when i do this with the re-encoded LOTR you can see artifacts .....so maybe if it was a newer better quality TV i might see less artifacts...is this a logical thing or not????

3: with my second pass with 5 pass vbr ...if i set also a min kbits together with the avergae kbits..will it make a difference?? So in this case lets say:

5 times vbr
max of 9800
Bias of 0
Global average kbits of lets say as high as possible depending on the file size (plus the audio/subs you have to add)
plus now a min of 2000 (so if i add this ass well)


I must say ...even in the beginning of amelie ....just when its starst there is a moment when the logo of the flim producers come up UFG or something .....even at that point with high contrast settings on my TV i can see the artifacts ...but after that there is very little areas in the movie where its very dark...so with the way i explained above i got amazing quality!!!...just strange that it only happens with movies that have dark moments.....

PS: All movies are PAL 2

What :) ? Why am i an abomination all of a sudden?? :( ...I thought that these forums are here for helping each other and to share our expereinces!!! Just wanted to get a better quality :) so i am sharing my experience here ......and naturally i posted to check and see whether it is something that i personally am doing wrong within this process that might be causing this??? Heheheh :D So would be nice to get some answers to my questions above??? :) instead of calling people abominations ??? :D

Nah...not you. The project itself. Regardless of whether anyone likes the film or not, they can't deny what a perfection in transfer to DVD, both video and audio, it is. The DVD, as a whole, is the best transfer I've ever seen. I just feel like doing anything to it is ruining it.

Anyway, yes, it's a place to share experience but also to share opinion. hehe ;) Just wait for an answer. You probably haven't gotten one yet because I'm about the only person awake all night long whereas most people sleep.

Heheh I actually totally agree with you ....you really should buy this DVD ..but i had a chance to borrow tha sucker from a freind ..so i thought i should have ago...and it really turned out to be great ..i must be honest CCE rocks ..however ...i guess the larger the DVD gets the larger the film gets ..the less of a chance you have to set high average kbits ...and the higher the chance for macroblocks:(......

ps: sorry about that little misunderstanding ..whooppsss:) ....though i guess i could be a little bit of an abomination sometimes:) :devil: hahahaaha....i am always happy that you are always here for us:)...thanks to you i learned how to do single PGC's:)))...well i do hope that some people give their opinions about the questions they will really help:)
