True 24p Television?

Good afternoon,

First of all, let me start by apologizing if this is not the correct place or forum for this topic.

I would like to purchase a widescreen television for my film work. At this point I am looking at the Sony Bravia Series 's' and 'w'. The 'w' series claims to have "true 24p". Does anyone know what this means, and what it might mean for footage shot on my DVX in 24p?

Might I also add: what does it mean when Sony claims it's TV is 'HD ready' as opposed to 'Full HD'?

Thanks for your time on this.

Cheers,
John

This is possibly tough for you to understand.

1. Not sure at all what they mean by "true 24p". DVDs can playback at 24fps but television is not broadcast at 24fps.

2. Your DVX doesn't shoot 24fps. It only shoots at 29.97 fps since it is NTSC. It puts flags in the 29.97 video stream that allow an editing system to remove the extra frames, resulting in a true 24fps signal, but then it's not NTSC, it's designed either for the web or a film out. So there is no way to playback your DVX footage on your tv at 24fps unless you edit it and burn it to a 24fps DVD. But then I know that the DVD is re-converted back to a 29.97 signal because there is no such thing as 24fps NTSC signal.

Got it?

Realistically, you are looking at a bunch of advertising hype.

HD ready means the televison does not have an HD tuner built in.

Puredrifting,

Thanks for the reply, and your explanation is crystal clear. I know all about the DVX, 29.97 and the various Pull Down methods used to achieve 24p that's why I was a little confused by a TV advertising itself as true 24p.

Regarding the HD Ready, how critical is it that a TV has the HD tuner built in? If it isn't build in to the TV then must it be in the transmitting device (eg. DVD player)?

Hi John:

It all depends on how you receive TV in your area of BC. If you receive over the air broadcasts via an HD antenna, having an HD tuner in the television is handy. If you use cable or satellite, it won't matter in the least, your cable box or DirectTV/DISH box will serve as your tuner.

I have not seen a DVD player or recorder yet that includes an ATSC tuner, so you need to think about how you now receive your signal and how you intend to receive it in the near future. I was looking at some new DVD recorders today and they (Sony and Toshiba) made a big point of having a sticker on the box that says, "this product does NOT contain a tuner". Since the Feb 2009 official DTV changeover, few manufacturers are putting analog tuners into products because they will be useless in a few months, at least here in the U.S., not sure what is happening in Canada with DTV. And I think that ATSC HD tuners are still too expensive to put into lower dollar products besides expensive televisions, cable boxes and satellite receivers.

I have DirectTV and there is absolutely no over the air reception here where I live so I could care less about my TV having a tuner. OTOH, my in laws in LA can receive crystal clear free television from all of the LA stations as they live very close to Mt. Wilson where all of the transmitters are.

Just depends on your situation.

Dan,

Many thanks for your patient help. Actually, I am living in Yangon, Myanmar at the moment and so will be using the TV exclusively to watch DVDs and anything I shoot and edit with my DVX.

Hi John:

Just be prepared to be disappointed with the picture quality of any NTSC source on any HD set (unless you have an upres DVD player, which can look halfway decent).

The upres NTSC video on almost all LCDs and Plasmas looks like hell. A cheap CRT looks so much better with NTSC signal. Guess the manufacturers figured, "why bother worrying about how to build in decent up-conversion when HD is the hot thing?"
