TV Framerates? 2-Part

[kisk]

1) How many fps does a NTSC television put off?

2) If I plan to capture, burn, and play back thru the television, is it best to:
--- A) Capture at the tv framerate and encode at tv framerate
--- B) Capture at higher framerate and encode at tv framerate
--- C) Capture at higher framerate and encode at higher framerate

I'll be burning my captures to dvd and playing them thru a standalone player.

Thx,

oops... also:


Just for reference, what adverse effects would I see if I were to capture, encode at framerates that don't match a television.

A DVD has required framerates.
23.976
29.97
25 for PAL

If you dont use those the Authoring program won't like it and
the player wont like it. And the sound will be out of sync.

NTSC TV is 29.97 frames/sec split into fields.

The capture card will only capture what comes in . You can't change it.

You should capture and encode interlaced at 29.97

encode at framerates that don't match a television.

Then it would not play. NTSC is 29.97 fps. Stick with that.

All that info and more is in What is DVD.

Foo beat me to it. :c)

23.97fps is not valid for DVD as such

You can encode at 23.97fps with 3:2 pulldown. This adds flags to the mpeg stream that allow it to be played back at 29.97fps. Without these flags 23.97fps is invalid for DVD.

Mpeg-1 on dvd must be 29.97fps as mpeg-1 does not support pilldown.

This is all for NTSC of course.

hey thanks for the info

I'll just stick to encoding at 29.97 :P
