How to find out if NTSC or PAL?

[badtz]

I have a DVD Backup (VIDEO_TS folder), and was wondering how I would be able to find out if the DVD is PAL or NTSC? Is there a mac program that'll find this easily?

Also, is there anyway to convert PAL to NTSC [dvd]?

Thanks

I check by opening the VOB or m2v with QuickTime, getting movie properties (command-J), selecting the video track in the left popup menu, and 'frame rate' in the right one. PAL is 25 FPS, and NTSC is either ~24 or ~30 FPS. I think you need the MPEG2 playback component for that. I think MPEG2Works has a PAL<->NTSC conversion function.

Thanks for the tip Wise Weasel!!

Though, mpeg2works seems like a lengthy process that doesn't 100% guarantee results


one gripe though : Quicktime should let you drop a mounted DVD onto it to have it open [i don't think dvdplayer does it either] ... that would be more convenient then having to navigate to the video_ts folder.

thanks again!!

VLC will do that for ya

Wiseweasel mentioned NTSC can be 24 or 29.97 frame rate.
For the material to be watched as film dvd, should it be encoded to 29.97 frame rate?
I was using mediapipe to do the conversion for a PAL movie, the result did change to NTSC, but the framerate stays at 24.after 24 hours of rendering.
Then i use quicktime mpeq 2 convertor, for another 24 hours, not only the frame rate increased to 29.97, the file size also increased by same proportion .
So if i burn two dvds with each video file, which one will look better?
choice 1: mediapipe video, ntsc, frame 24, file size 2 G.
choice 2: qt render of the mediapipe file, ntsc, frame 30, file size 3G

From Google search i found the following
NTSC video uses a frame rate of 30 (actually 29.97) fps which is identical to NTSC video material. Film material is usually converted from 24 to 30 fps by a '3/2 pulldown' whereby frames are repeated to convert the 24fps film to 30fps video. However this is not necessary for DVD since the player can carry out the frame rate conversion. Therefore the video can be stored on disc at 24fps and displayed by the player at 30 fps. The encoder embeds MPEG-2 repeat_first_field flags into the video stream to make the decoder perform 3/2 pulldown.

What i don't know is when i used the mediapipe for the conversion whether it embeds the flag in the video file.
I guess i have to burn the two video files, one from mediapipe rendering and another from qt to find out whether it matters or not.

I burnt the two dvds.
They look identical.
Both don't syn with audio ac3 file.
I am giving up on using mediapipe.
The only one that works for me so far is mpeg2works by serbian.

the only two methods that are tried and true for me is mediapipe (has quite a learning curve) and movtoy4m - > mpeg2enc (which is the method that mpeg2 works uses, although this method VASTLY pre-dates mpeg2 works) I wish the frame rate changer pipe worked in both CLI and GUI modes then i could wrap it into a project i'm workin on.. oh well. And a new tool was added to the mjpeg arsenal in 1.6.2 to change frame rate but i have yet to have a successful run w/ it...

I use mpgtxwrap for this. Only doscovered it a few days ago, just drag a vob or other video file onto it ans it gives the following sort of info:

Mpeg 2 Program Stream File [Video/Audio]
Muxrate : 10.08 Mbps
Estimated Duration: 18:23:04.08s
Aspect ratio 4/3 (TV)

I tried mediapipe after Bilestyleposted the recipe.
But i ended up using the automatic arguments generated by mediapipe and the pictures came out proportionally wrong.
Also the forum at mediapipe seems to have been abandoned , with no moderator.
They also named their mpeg file mpv , which Sizzle would take after i change the file extension to m2v.
Just not very user friendly.
