Simple but most likely stupid TELECINE question..

[axolotls]

1) If you have a telecined NTSC VHS (29.967fps) that you want to convert to NTSC DVD. Is there any reason why you would want to inverse-telecine it back to 24fps if you just want to view it on an interlaced TV?

2) Would it preferable to inverse telecine the NTSC VHS and encode as a PAL DVD?

3) Audio Speed-up issues for both?

Thanks.

1) I don't thnk so, it is in the right format for tv as is.

2) Do you need a PAL for some reason? (are you not in NA?)

3) Don't quite understand what you mean there.

1) Yes... A video encoded in FILM takes about 20% less space than a hard-telecined video. This means that you can use a higher bitrate on the IVTC stuff.

2) You almost HAVE to IVTC an NTSC before a PAL conversion. A film to PAL conversion is usually just a sped up version of the film version (24->25fps).

3) For PAL, can be. For IVTC, no (the TIMING does not change).

I am NTSC, but have the equipment to play PAL VHS/DVDs and SECAM VHS.

I dislike the 3:2 pulldown and was wondering if I could inverse telecine it to 24fps and play as NTSC (I don't think I can, but wanted to dig into other's heads here -just in case-)

My 3rd question was that since the original Film source was 24 FPS and then telecined to 29.967 FPS NTSC, wouldn't the audio have been sped up 4 - 6 % on the VHS NTSC? or generally is it pitch corrected during that process?

Thanks. Unless some one else chimes in here, I will acquiese to living with 3:2 pulldown...

What do you have against a 2:3 pulldown? If you have ever watch an NTSC DVD, then you saw a 2:3 pulldown in action.

It sounds like you are confused about how an NTSC signal is created. Your VHS videos are HARD TELECINED to 29.97fps, because that's how they were originally transmitted. The original may or may not have originated at 24fps, but most cases it did originate from 24fps.

You can just go ahead and encode the hard TC stuff and live with the loss of the potential quality increase. But since these are video tapes, the quality will be limited to begin with. But with a good IVTC, you can pick up space on your DVD, which means that you can squeeze more onto your DVD.

If you are just starting with this stuff, then I suggest that you just go with the hard TC stuff until you learn more advanced techniques. As you get more comfortable and more familiar with the subject matter, you can start picking up the improved techniques.

Thanks. I am speaking of a specific VHS I am converting that is definitely telecined. 3 progressive frames followed by 2 interlaced ones.

I am trying to squeeze the best that I can. And right now the DVD conversion is much better than my source, as I filter/reauthor the audio stream, as well as filtering/cleaning the video source.

I know what I am doing in the cleaning/filtering arena of video and audio, but have always been pretty ignorant on the 3:2/telecine arena (a weak spot that I am trying to strengthen.
