There is probably a software somewhere that will do this for you, but I don't know of one. However, you can calculate it.
Frame Number = time(in seconds) x frame rate (frames per second)
NTSC frame rate = 29.97 frames per second
PAL frame rate = 25 frames per second

Therefore, if you wanted to find the frame number of something located 1hr-9minutes-4sec into a movie in PAL you would have
1hr = 3600sec
9min = 540sec
4sec = 4sec
Total 4144sec
Frame number = 4144 x 25
Frame number = 103600

For NTSC you can use 30 frames per second unless you need precise, precise, precise numbers. You'd be "off" by three frames every 100 seconds. Also, some systems give time in 00:00:00:00 in which the last 00 is frames. You must add this number to your calculation.

VirtualDub lets you jump to either a specific frame or a specific time (Ctrl-G, I think). The status bar tells you both the frame number and the time for the frame you're looking at.

thx for reply.

I need to know the frame no. of dvd movie, so cannot use virtualdub.

About the calculation, how do I judge whether the dvd is pal or ntsc?

Most of the time it says NTSC or PAL on the back of the DVD cover. A quick guideline is that all european (R2) DVD's are PAL, Japanese (R2) and American (R1) DVD's are NTSC. Or you can open the vob in DVD2AVI, press F5 (preview) and check the statistics window. It will say PAL if it is 25 fps, and NTSC or FILM otherwise.

If you have IFO Edit open the VIDEO_TS.IFO and the properties that appear in the lower part of the screen will tell you.

The other method is an "educated guess." NTSC is the television standard used in USA, Canada, Mexico and Japan--Mostly. PAL is the television standard "widely used in Europe and throughout the world"--this from the "Digital Fact Book" by Quantel. If your DVD was produced for use in one of the countries I mentioned then it's probably NTSC. The oppposite is also true.

The most definitive determination is the IFO Edit method.
