about 3 hours, will fit on one DVD... why is that?
 
1. On the main page, it says that at full D1, you should be able to fit about 6 hours of video on one DVD...that is about four movies. I am encoding 2 Fast 2 Furious...and with a bitrate max of 3000, the video size is well over 2 gigabytes. At that pace, only two movies, or about 3 hours, will fit on one DVD...why is that?

2. How do you guys do screenshots of your KDVDs. I know in Virtualdub you can do an image sequence, that is what I want to do...but, I can't get it to open up my .mpg files that are created in TMPGEnc, it says that there is no video found...is there some other program that can do this for me?

Because you're doing something wrong :!:
At that bitrate, as you said, you'll only fit about 2 movies.
Use CalcuMatic to get the correct average bitrate, so you can fit 4 movies.

You need VirtualDub MPEG-2 to open that file. Get it here: http://fcchandler.home.comcast.net/stable/

He use a MAX bitrate of 3000, not an AVG bitrate of 3000.
The thing he does wrong so it that he do not do any file size prediction.

Which encoder do you use man ?

I use TMPGEnc. I've been using 2.58, but I also just got XPress...as far as my first question...the problem was that both me and TMPGEnc are stupid... :roll: It was just because TMPGEnc's file predicition was WAY off.

kwag...thanks for the link, that was exactly what I was looking for.

One more question for all you KDVD experts...

I am using TMPGEnc EXpress...As far as I know, there are not any KDVD templates for it yet. I changed the matrix to the KDVD "notch" matrix, and I changed max GOP to 30 (my source is NTSC, 29.973) Are there any other settings that need to be changed, what with I,P, and B frames?

Don't do that :!:
Keep your GOP at 18, because that's the MAX NTSC DVD compliant GOP size.

No. Also remember that if your target is 352x240 or 352x480, you have to encode 4:3 for DVD compliance.
704x480 and 720x480 can be encoded as 16:9.

Wow...does the video have to be 29.97 fps to be DVD compliant...or can you have it 23.976? If my source is 23.976, is there any problem in converting it to 29.97? Thanks again :)

29.970 is the only standard compliant framerate.

But... you can simply apply what is called a "pulldown" on 23.976 sources in order to have them seen as 29.970 by the player.

So :
:arrow: is you have already encoded your videos in 23.976, just find the tool "pulldown.exe" and apply it on the video stream.
:arrow: else, find in tmpgenc were you can activate the "3:2 pulldown during playback" (that was the name in the former version of the tool).

Note: This can be done in MPEG2 only (pulldown does not exists in MPEG1)
