hi guys,
wondering if any of you have knowledge of dvd frame rates?
i know that NTSC is 30fps and PAL is 25fps, but what is the standard or maximum frame rate for dvd playback? i am currently designing a dvd for my company and would like to make it as slick as possible.

I've not worked with dvd myself, but as playback will most likely run on a tv / monitor 30fps seems more than adequate.

I don't see how the fact that a dvd is used will make much difference, I've always been told anymore than 24/25fps is wasted effort due to the human eye not being able to distinguish more than that... ?

yea, that's what i've always heard too, but if you look at flash - animations put in higher fps run so much smoother than ones on low fps. the same goes with games like quake 3 - 25 fps is almost unplayable for that kinda game, where you need 80fps or more. i'm just thinking that if i put it in a higher frame rate it'll look smoother on any animations. i don't think i'll need more than 30 or 40, but if i can use more, i'll consider it.

true, I guess it depends on what exactly your trying to do and how your doing it. The main reason for increacing frame rates in flash games seems to be dependent on the amount and type of scripting your using aswell as the overall complexity of your swf. Straight animation normally works fine for me at lower frame rates so long as there's not too much Alpha in there (though that's to do with processor issues anyway).

The DVD info I could find listed it as follows...

DVD Video Parameter Settings

* Frame Size: 720x480 (NTSC) or 720x576 (PAL)
* Frame Rate: 29.97 frames/second (NTSC) or 25 frames/second (PAL)
* Video Data Rate: 4~8 Mbps CBR or VBR (Constant/Variable Bit Rate)
* Audio Settings: Stereo, 48 kHz and 192~384 kbps MPEG audio

But I guess that's for straight video/animation playback. Will your DVD be viewed on TV's or monitors or both/unknown.

btw what are you using to produce the DVD?

Prole · 09-05-2003, 05:04

lovely

cheers dan!

i am using a program called DVDit! PE by Sonic to put it all together. tbh it's quite a simple program considering how much it costs. it has about 1/30th of the features of Flash or Director but costs more! and the interface looks so shabby!

You need to stick to a standard frame rates - other wise you could run into compatability problems. Not all players can handle NTSC just as not all players can handle PAL - so whichever you use (and i'd suggest PAL for UK based stuff) there's always gonna be someone unable to use it.

Standard PALshould be plenty fast enough - the standard celluloid film frame rate is 24fps and thats coped fine for decades.

What exactly is going to be on the dvd?

Prole · 09-05-2003, 05:20

my company create web sites and DVD advertising brochures. the DVD i'm doing will be a promotional disc that shows what the company does and will include text, images, motion video and animations. there will be sound included too.

is PAL 24 or 25 FPS then cos i'm getting conflicting information?

tomson · 09-05-2003, 05:24

PAL is 25fps.
