Widescreen capture?

[Nelson37]

I do not have a widescreen TV, so have never experimented with this.

TCM is airing Cleopatra in letterbox format this evening. The movie is quite long, and will be difficult to fit on one disk. What I would like to do is capture in widescreen mode with the black bars cut off.

I do real-time MPG, and may try a real-time IVTC, as well. (yes, I am a glutton for punishment). Oh, yea, may do closed captions to subtitles, too.

My question concerns playback on a 4:3 TV. Assuming I have a 2.35 to 1, or whatever, file, with DAR set correctly, and also assuming I can set a letterbox mode on the DVD player, will the player add the black letterboxing bars on playback? Or is such a file completely invalid?

The actual res of the captured file would not be 720x480, with the bars cut off. Would be 720 horizontal, but the vertical would be less than 480.
I guess I'm thinking a 16:9 video has some resolution other than 720x480, and that's probably where I'm way off.

The other way would be a re-encode, with software IVTC (possibly) and fresh, clean bars added. Is that the only way?

Nope it's the same. The DVD player adjusts the aspect. Be aware if you don't have true 16:9 source the black bars are part of the source.

Just for example if you captured a analog siganl that's letterboxed from a DVD player it's no longer full resolution. the black bars are part of the signal. I'll have to guess that the TV signal your receiving is the same. Otherwise it would be skewed on a 4:3 TV.

How do you do real time IVTC? I need to start doing that.

On MMC software, there is a "remove 3:2 pulldown" flag, which will work on a clean signal. Sensitive to changes in pattern and transmission problems, but works about as well as most software methods.

It is also possible to do this with a filter in some progs but takes a fast PC.

On the original question, I thought it was that way. The vid is a standard res on disk but is expanded on the widescreen TV. So the source would need to be some number greater than 720 in the horizontal, then?

What if I could capture at the proper resolution - this would be upsized from source, but the black bars would be removed - probably a bad idea but now I am curious and am wondering what would occur ... I hate it when this happens.

I don't know if I'm misunderstanding you but 16:9 on a DVD is 720X480. There's a flag in the ifo file that tells the DVD player that so it displays correctly, it adds the black bars to the output. If you capture that analog signal you'll now have a 4:3 video with black bars top and bottom.


Raw 16:9


Correct display:



As far as broadcast I'm not sure, I'd assume it would have to be a digital signal to get the full resolution if that's what they are broadcasting. I know all the regular TV braodcasts in my area are 4:3. We're low-tech.... :P
