Hi,
I'm sometimes a few years ago bought my first camcorder in Paraguay, at that time knew nothing of PAL and NTSC.
I have a couple of old recordings grad watched - all of which have 29.97 fps - synonymous with movie setting in the NLE with NTSC is 29.97 fps in it - is not specified with 30p/60i as in slashCAM camcorder comparison of the "Video resolution U.S.."
How to get to 29.97 fps? I figure it the meaning of the .., not 97! Because what is missing from the last frame on purpose, why? If a new 30 fps frame rate?
And with what program can convert NTSC to PAL clean?
Regards,
Martin

And with what program can convert NTSC to PAL clean? That makes every NLE auto.

The 29.97 fps come into force by the time since it was established a long time ago, in the conversion of black and white television to color, the color carrier that could with the sound bite, because you put the ink in a frequency range where the Sound was already.
That is why we have lowered the frame rate of 30 frames to 29.97 so as not to disturb Sound and ink each other.
In January 1950, the Committee was reconstituted to standardize color television. In December 1953, it unanimously approved what is now called the NTSC color television standard (later defined s.RS-170a). The "compatible color" standard retained full backward compatibility with existing black-and-white television sets. Color information was added to the black-and-white image by adding a color subcarrier of 4.5 × 455 / 572 MHz (approximately 3.58 MHz) to the video signal. To reduce the visibility of interference between the chrominance signal and FM sound carrier required a slight reduction of the frame rate from 30 frames per second to approximately 29.97 frames per second, and changing the line frequency from 15.750 Hz to 15,734.26 Hz Source: http://en.wikipedia.org/wiki/NTSC#History
And with what program can convert NTSC to PAL clean? After Effects, Vegas, Avisynth. There are many, you just need to know what you are doing.

These curved frame rates, there are unfortunately a lot of confusion - and, not least because of how the tables slashCAM like in connection with review of NTSC 30 fps, even though there actually 29.97 fps would be correct.
The confusion is thus complete, that there are actually synonymous cameras, making the true 30.00 fps - such as my Canon Digital IXUS 100 IS in video mode.
And with what program can convert NTSC to PAL clean?
That makes every NLE auto. Where "clean" of course is a matter of opinion. Depending on the material provides for a method or another "clean out".
The question is synonymous to whether the conversion is necessary. If the films are shown on advanced devices, there should be any problems running the original rate, eg in the form of a NTSC DVD.
Really a must is the conversion only if the material is mixed with such of PAL camcorders in a movie.
