If I want to become a cloud of bats, does each bat need a separate vaccination?

Is my TV chopping?

Yes, but it's supposed to. Like movies, tv is shot with the understanding that a certain amount of the visible-in-the-studio edge of the frame will be cropped out by the projection/tv set. The "tv safe" region of a video frame is the middle 90%. ("Title safe" is the middle 80%, the idea being that titles really have to be seen, so you should be extra-safe and give the TV manufacturer an extra 10% wiggle room.)

Well not canonically, no, but this is transformative fiction.

Is aspect info sent along with the picture? I mean, how does a standard TV know when to letterbox, and when to chop, or conversely, how does a widescreen TV know when to squish, when to show wide, and when to slice off the letterboxing?

Also, what was UP with the Phillips?

The Phillips just sounds screwy. And you know, I have no idea how a television detects aspect ratio. It must be part of the signal. (Which makes me wonder if it affects the frame rate, the way color does. Huh.)

Huh. I have the Spike Jonze DVD of videos - when I play the one with Christopher Walken on my Mac, there's a scene where I can clearly see the reflection of the camera in a mirror. The camera gets cropped completely when I play it on a TV.

And you know, I have no idea how a television detects aspect ratio. It must be part of the signal.

When I set up my new DVD player, it asked me if I had a wide aspect-ratio TV, so it would know how to handle letter-boxing. (If I had a wide aspect-ratio TV, the black bands above and below the picture in a letter-boxed movie would be moslty gone.)

But, you know, I also have no idea what a TV does with the various aspect ratios....

Hey. New board.

But, you know, I also have no idea what a TV does with the various aspect ratios....

As near as I can tell, it doesn't. I think that most TVs are pretty dumb when it comes to that sort of thing, and you have to tell it manually what to do.

If you have a 4x3 TV

  • HDTV content (16x9) must be received by an HDTV tuner (almost certainly not built into the TV). You will tell the tuner that you have a 4x3 TV, it will letterbox (or maybe pan/scan on the fly) and send the new 4x3 signal to the TV.
  • DVD content (1.85:1, 2.33:1, or 4:3) will be letterboxed as necessary by the DVD player, which also must be told you have a standard 4x3 TV
  • Normal TV content can be tuned directly by the TV, because it's already 4x3. When you watch a letterboxed signal on, say, TCM or something, then you're actually getting a 4x3 signal. Those black bars are actually contained in the signal, unlike with anamorphic DVDs.

If you have a 16x9 TV

  • HDTV content will be tuned by either the TV or an external tuner, and sent to the TV, which will be set to "Full", which means "widescreen content on a widescreen TV, yay!"
  • Widescreen DVD content will be letterboxed as necessary (just a tiny bit for 1.85:1 movies, a bit more for cinemascope 2.33:1 ones) by the DVD player, which knows you have a 16:9 TV.
  • Normal 4:3 DVD content will be sent directly as 4:3 video, just as if you were talking to a normal 4:3 TV. The user is expected to set the TV to "4:3", which will display the signal in the middle of the screen putting nice gray bars down the side of the widescreen television.
  • TV content works exactly like 4:3 content.

Basically, widescreen TVs almost always work perfectly with widescreen movies and HDTV content (only little bars when there are bars at all, and you don't have to play with the TV to make them work, just set the tuner/DVD player once), but make you push buttons to display 4:3 content unsquished (squishing, however, is NEVER required, at least I can't imagine it ever would be. The Best Buy salesman was probably kind of dumb.) 4:3 TVs are the opposite.

In the future, when I have a widescreen TV, I expect it will only annoy me when I want to watch DVDs of old shows. All new shows are being filmed in 16:9 HDTV anyway.

(For those too lazy to read and grok all of the above: I'd recommend buying 16:9 TVs. They're a little more work, sometimes, but they'll never squish anything if you know what buttons to push (though normal TV will have bars down the sides), and in the future, when HDTV content is the way, the truth, and the light, you'll be really happy you have it.)

I'm gonna buy a new TV soon. I'm gonna get a 16:9 HDTV, but pro'lly with a picture tube, as I don't wanna pay the prices for a big enough plasma or LCD screen.

This was not the case with my in-laws widescreen HDTV. It displayed 4:3 and 16:9 television just fine, as well as DVDs, with no additional buttons to press.

The only real problem with the TV is that RotK looked so sharp that a lot of the theatrically beautiful composite work became painfully visible.

See, the Best Buy guy (I know, I know) tried to assure me that it would crop vertically, so 4:3 broadcast 16:9 would look better. But who knows? That TV was squishing the hell out of the picture, and in the end, for a 26" diagonal, you end up with very little vertical screen height.

I just bought a new TV, 27". I thought about HDTV, but figured to not spend the cash now, since I turn TVs over every three years or so. It'll be good.

Are you ready to be strong?

I have a program that moves songs from iPod to iTunes, but I don't remember what it's called now. If you want I'll check tomorrow.

move out and draw fire

Is there a (possible for the home amateur) way to record the sound from a DVD without the track that would go to the center-channel speaker? I need a soundtrack of WWII background, and I wanted to use the opening 20ish minutes of Saving Private Ryan, but I don't want it to be immediately identifiable, or to pull attention, so I'd like to remove the dialogue, etc. I can get this while listening by disconnecting my center speaker, but I'm wondering if there's a way to somehow filter out that track while recording.

Help?
