Whats the difference between "NTSC" "NTSC FI

[Foxhound]

WHat is the difference in quality if there is any between the "NTSC" "NTSC FILM" and "PAL" when using Tmpgenc. Can u use any of thoes even if it doesnt fit the set frame rate of the video that your encoding?

[spiderman2k1]

NTSC is 23.97 frames a second NTSC is 29

And shy away from encoding to a format with a different frame rate. Youy are practically asking for jerky video.

well....

over, NTSC vs. PAL really depends on what type of TV you have....if you have NTSC TV, then you need to output as NTSC...if you have PAL, then output PAL...there's really not much choice here.

---------

if you need to output as NTSC, you have a couple of choices. for quality purposes, NTSC FILM (23.976 fps) will usually produce better video quality than NTSC (29.97 fps), given all other encoder settings are constant.

the reason for higher quality is because there are less frames to encode per second (23.976 fps vs. 29.97 fps). hence, given the same bitrate, each frame in NTSC FILM will receive more bitrate than NTSC->higher video quality.

as for jerkiness, when you output your video as NTSC FILM, you need to make sure you check "3:2 pulldown on playback" so that your dvd player can play back the NTSC FILM (23.976 fps) as 29.97 fps when you watch it on your TV.

however, you should only make your output 23.976 fps + 3:2 pulldown, if your source commerical DVD is PROGRESSIVE, NON-INTERLACED. if you use dvd2avi, you can load the vob files and press f5. an info box will appear, giving you the video details. the VIDEO TYPE should be FILM (or greater than 90% FILM)...and the FRAME TYPE should be PROGRESSIVE. you may need to watch the info box for longer period of time, as intros are most often interlaced, while the rest of the movie isn't.
