Video Source FPS help....

[tr3]

i was at this page http://www.vcdhelp.com/tmpgenc.htm
and it said

NTSC if the video source is 29,97
NTSC Film if the video source is 23.976
PAL if the video source is 25 FPS.

my video is none of those, it was 24.000
which one would i choose?

23.976

24fps is pretty much the NTSC(film) for the PC . Load the video in TMPGEnc and choose whatever NTSC(film) Template you like and encode. The video will stay in sync with the audio, you won't have a problem.

my dvd player has a problem with 23.976 videos so I have to check "3:2 pulldown when playback" for mpeg2 and "3:2 pulldown" under the "advanced" tab for mpeg1

thanks alot for the quick reply!

i need help again... trying to burn deuces wild, and when i do it it says 12.500 fps... am i doing something wrong? (btw the FPS is on the original avi file i dled) TIA

[Big_Jit]

If the fps is 12.5 then it is better to leave it alone and not encode to mpeg for vcd output.

but...

you could open the file in TMPGEnc and on the output framerate tou can choose 12.5fps (internally 25fps) and you can create a PAL Compliant VCD. but the vcd might not work. I would sugggest encoding 5mins worth and then testing it in your dvd player. I did this with a movie that i had and it WORKED!...

is there any general rule? what if i get 20fps or 10fps?
thanks

IMHO there is a general rule. Never convert the framerate. If there is a slight difference, e.g. source is FILM and target PAL, you may speed up the movie. But every framerate conversion, that is done by deleting / duplicating frames is crap.

[tr3]

how would i not convert it and still be able to burn it to (s)vcd

[Truman]

If you want to convert it to VCD by all means, you can do it. Load the 12.5 fps source and select a VCD template. If you are going to convert to PAL, every frame will get duplicated. You can not expect a smooth playback. Simply keep your hands off low framerate sources if you are aiming for (S)VCD.

thx

[flyguyj]

can someone please teach me the differences between the framerates, like, when to use which. i never know when to use 23.97 or 29.97 when converting dvds. i know the 23.97 says (film) next to it, but what does that mean??

also, any experience with DVDx 2.0?? it seems as if every single time, regardless of my settings, it tells me it has to perform a pull up/down. what is going on??

thanks for your help guys

Framerates:

23.976 = NTSC(film) America/Japan
29.97 = NTSC America/Japan
25 = PAL Everywhere Else

North American Films use the 23.976 framerate that's why film is placed beside the framerate so as to distinguish between the two NTSC Standards. 29.97 is the framerate used in North American television broadcasts as well as VHS tapes and other media (as 25 is used in other places for the same thing) but what you have to understand is that these are the digital rates. Television and VHS tapes are analog sources so they use a frequency instead of a framerate.

Like 29.97 is actually 59.94hz (or 60hz) and 25 is 50hz...

The reason that when you go digital the frequencies are converted to frames is because the analog picture is made up of 2 fields and when combined creates 1 frame. This is why framerates are 1/2 of the hz frequency.

You should use whatever the original framerate of the DVD is. DVDX should tell you what the framerate is.
