What is Telecine?

[egov]

Sorry for the stupid question, but What is Telecine? What is it good for?

[KRSESQ]

Telecine is the process by which motion picture film is transferred to video. In the U.S. video runs at 30 frames per second and motion picture film runs at 24 fps. So a specially designed projector is required to syncronize the two without the image strobing.

Telecine systems can vary widely in complexity and quality of results, from a simple projector - camera setup to the professional Rank Cinetel system.

Planning to transfer old movies to video?

Technically speaking TeleCine refers to film-to-video or video-to-film transfer of footage. Which direction depends on how the movie is being shot and what distribution format is to be used.

In basic terms it refers to the conversion from films 24 fps to tapes 29.970 fps for NTSC (25 fps for PAL) or the reverse.

In the olden days, say up to 2 years ago (G), film-to-tape telecine was used the most in order to get a movie ready for TV.

Today things have changed and many studios are shooting on high resolution tape, so video-to-film telecine has become commonplace so they can be shown in theaters.

In the next few years theaters will no longer use film but instead will use high powered digital video projectors, but the format to be used is still under "discussion" (meaning: yet another standards war).

Thanks for the respond!

With other words, can I feed in NTSC signal into my Matrox G200 and output it LIVE as a PAL signal on a VHS tape?

Excellent input, Kevin & Doc !!!

I just wanted to add that nowadays, the fps rate for filming is adjusted to 25fps for PAL TV productions (maybe they do the same for NTSC, but don't know).

The company I work in offers the real high end for high definition telecine and color correction and since you both seem to have quite some knowledge, I thought you might be interested to have a look on where I have the pleasure to work in the visual FX dept ...

About your request, egov:

What kind of G200 do you have ?

You'd need either the Marvel or the RR-G addon and I don't know whether those are capable of a color system conversion on the fly.

Cheers,

Mine is an ordinary Matrox Marvel G200 TV

Maggi,

Neat place! Mebbe the next time I'm on that side of the pond I'll drop down from Sweden....

Egov:

Check this site for an excellent overview of PAL/NTSC conversion:

As for inputting NTSC and outputting PAL, your best option may be to simply try it.

Open your powerdesk control panel, choose TV Output, and set it to PAL. Be sure to set the advanced TV settings:

Brightness: 167
Contrast: 255
Saturation: 138
Hue: 0

Then open Video Tools and see if it will let you set the video input standard to NTSC. If so, then just roll your NTSC videotape and see how it displays on your PAL monitor.

I have the Marvel G200 also. I'm working with VT 1.52 and PD 5.41. This combo has given me the best stability for my system. I'm a little scared to play with my settings, and I have no access to PAL equipment, so I've never tried this. None of this may work. Someone else may have a better suggestion. Anyway, lots of luck. Let me know if this was helpful.
