Hi All,
I'm finishing up a giant project and it's already a few days overdue-
my problem comes in when i pick reduce interlace flicker in dvd-A
it go's from 3gig to 5.5 and if i use the optomize option the disc
freezes up and has glitches-
I rendered each part in vegas with reduce interlace flicker because this has been a big issue before -
So my question is will it make any difference if I use it again in dvd-A

I am really stuck and it takes hors to make the disc ,so any help soon would be great,and so------ apreciated

Laura

I'm confused, Laura.
You have the project rendered, but when you select the "Reduce Interlace Flicker" option for menus/stills in DVDA, it's jumping the file size from 3 gig to 5.5 gig? This would suggest that you're telling DVDA to reencode/recompress the file.
When you finish the project in Vegas, what do you do with it? Are you rendering to avi in Vegas, or to mpg?

I put each part of the project together in vegas added transisions titles ect ....and then i rendered each part as a mpeg
I went to dvd -A - made a menu -imported each part i made in vegas so I had three parts (three buttons) , I then added chapters
to each one and I want to make disc ,the project size is 3.2 -but if I reduce interlace flicker in dvd-A , it pushes it way over to 5 .5 gig

The Reduce Interlace Flicker you're referring to is in the General Tab for the menus?
How long are thhe menus?
Under Oprtimise, how much of your project is compliant, is it saying that the three already encoded mpeg-2 files need re-encoding?

I'm suspecting that somehow you've made the actual videos part of the menu, when you select Reduce Iinterlace flicker DVDA thinks it needs to re-encode all the video which it'll do at the project bitrate and audio encoding you've set at the default.

You do realise that the Reduce Interlace Flicker option in DVDA only affects the menus, not the videos?

I picked a theemed menu page -
changed the picture -added a song
Dragged and dropped all three parts of my project
Pictures mpeg
Video-mpeg
After mpeg
adjusted menu stuff cropped button images
went in to each one ,added the chapter markers ect-
that is when i noticed the option to reduce interlace flicker was also in each project under general-so i clicked it 4 X all together 1 for each part of my project -1X for the menu page -

Part of the question is, did you use a whole video for your menu button? Or did you create a new video for the menu button. In other words, it might be you've got the same vid on there twice.

it was a blank menu and then i dragged the mpegs in and it made it's own button -so i bet your right because i usually have to link to the mpeg this time i did not-it seemed just to be there

If you drag a mpeg into a blank stock template it'll create a button / link for that video automatically, do it that way myself without issue.
However I don't leave the thumbnail there from memory so maybe, just maybe that's the problem. If DVDA tries to create an animated thumbnail then it has to encode the menu page and how big that is, is determined by how long you tell it you want the video of the thumbnails. Hoever that'd be the same regardless of the Reduce Interlace Flicker setting, I'm confused :(

Yes, but if she has a one hour video, and drags it as a button, it's now a one hour menu button that has to be encoded, which is now a separate video from the one-hour main feature that was used to create the button.
Create a short video for the button, is the easiest way to do this, or use a chapter sequence.

I don't know if this makes a dif but under the button properties
I inserted a jpeg for button media -
For my immediate problem I wasn't quite sure what to do so I left
the reduce interlace flicker on yes for my 55 min slide show as this is where I run into the bad flicker problem the most and
on yes for the menu and on yes for the 3 minute mpeg and turned it off for the 45 minute video ,this braught the final project down to 4.3 Gig and allowed me to leave the bitrate at 8. wich was 91%
I'm just about through watching it ,there doesn't seem to be any
problems -Is 8 a good setting I think it was the default and i beleive somewhere i read a setting for how much of a percentage of a disc you should leave empty ,but I don't remember off hand

Thank's for the imput
I wanted to try it with leaving the interlace flicker off on the mpegs but
with my deadline being tonight I would not have the time to go through the prosses again if I was wrong -
