DVDlab: menu images compression (+)

[fmilovanov]

Hi folks,

I've recently downloaded DVDlab trial version - it really does great job, but I've got a little problem with it. I want to merge 2 DVDs into one and I'm trying to re-build menus. I capture the menu picture from the original DVD and then paste it as a menu background into DVDlab. It works fine.... before I compile DVD. Once I compile it, the resulting menu images look like DVDlab applies JPEG-compression with a very high ratio - pictures in the compilation look much worse than the original ones.

Does anybody know how cat I fix this?

P.S. Sorry for my english - it is not my native language.

i haven't this problem ...
i use png (quality 8, about 400k per image) at 720*480 (dim is fixed in dvd-lab)
Sorry too for my english ;)

buzzqw, I've got all the images in PNG at about 400k average size (from 361 to 475) - and I have this problem. The problem also hapends if I just put a text (about 40pt font!) in DVDlab - it also looks deeply compressed in a compilation!

By the way - what do you mean on dim is fixed? Is this a kind of config parameted I miss? And what is your version - I've got 1.3.1.... http://forum.ixbt.com/shuffle.gif

As an example - go to http://chat.portal.ru/DVDlab/ - DVDlab*.png are screen captures of DVDlab in simulation mode, PowerDVD*.png are captures of the compiled DVD in PowerDVD. Especially the *-txt.png files :(

dvdlab accept images of different size, but as specified in manual, best size is 720*480.
I use 131+1.4beta (not concerning this problem).
Sorry, try using fixed dimension 720*480.

buzzqw, I use PowerDVD's captures as a background and they're exactly 720x480 pixels. The DVDlab-txt.png file is nothing more than bundeled DVDlab's background with the text placed on top of it....

[fmilovanov]

buzzqw ok, to avoid talking about nothing, here is the deal. I've created the very simple project in DVDlab: http://chat.portal.ru/DVDlab/test.zip - one menu with bundeled background, 3 text boxes and one link and one bundeled movie. Would you (or anyone who reads thit thread) download it, compile, run under software DVD player (I use PowerDVD), capture the menu screen and send it to me to fmilovanov-at-yahoo-dot-com. Then I can see if it is only my problem or I just cannot descibe it properly :)

OK !
Now i see what you mean ;)

Well, i think the main problem is a combination of factors:

1) Font chosen : quite big indeed (i would prefer a courier), and you check even bold
2) Drop Shadow: Fat , "hard" could produce better result
3) the slider after colour (don't remeber name... :scared: ) : the shadows is very near the script

Btw, i like yellow but isn't best colour for reading

Thanks

buzzqw :) But the most problem is this happends regardless of font size, face or wiegth, shadow type or color combination. The same effect is if you use a plain picture as a background. The problem is (it looks like) that DVDlab applies a high-ratio JPEG compression that produces these artifacts. The question is how to avoid it.

It looks like I've to e-mail MediaChance folks directly.... http://forum.ixbt.com/rolleyes.gif
