Frage von silentzero:
I take with my cam Progessivmodus always on, so full and then playing the images via FireWire. In my editing program (liquid) may Edition is now set at the effects if these fields or in frames to be rendered. What am I supposed to take as s.besten?
I have until now always clicked frames rendering, but now I'm thinking whether this is really important because the television shows it anyway again into fields.
How's that with the Halbblidern at plasma or LCD TVs? Show the fields still synonymous?
Antwort von Udo Schröer:
If your camera stores a full screen and you burn this on DVD, the picture is available as synonymous with purchased movies on DVD in full screen. There are DVD Player (Pal Progressive scan) reflect this full screen on the YUV output can. Although the use is only slightly when the TV which can be synonymous, but it does not hurt. Both TV and DVD player to give back through S-video or composite, the picture in the normal way than field. In the future, will support more and more TV Sets Pal Progressive, and then you have clear advantages in full screen.

you've got the xm2. Can the 25p at all? I thought not.

The only downside to full-screen mode is that the exposure of the camera sensitivity decreases by about 150%.
Antwort von silentzero:
Yes, the XM2 is 25p.
What do you mean by 150% less exposure sensitivity? Is not that a bit much?
Antwort von mdb:
The only downside to full-screen mode is that the exposure of the camera sensitivity decreases by about 150%. And what is worse with the motion resolution?
Antwort von Jan:
Yes, the XM2 is 25p.
Sorry, but I can not remember s.meiner old XM 2 have had a reel 25 P circuit in which L 2, it is well known.
The 25 P in the light sensitivity decreases is well known, but really to say and write 150%?

150% of the way, represent only about 2 1 / 2 f-stops ...
Is also half the wild ...
Antwort von silentzero:
I can assure you, however, the XL2 can record 25 frames.

Now you make me nervous, so I should have slept?
Where did you set (clear menu, but more accurate?)

Antwort von silentzero:
So, in the menu on Cam. Setup. Since then set to movie mode and either normal or frame. Normal is the normal recording with 2 half-frames, frames are 25 frames.
But maybe we could once again return to my real question, if this could give someone else :-)

January 150% sounds like a lot. But an aperture as I know 100%. In the p mode, the chip read out the Camera line manner, in the i mode, two lines can be coupled to read. This leads, according to the magazine cameraman s.Lichtempfindlichkeit to the loss. With a longer exposure time, which can be partially offset. But pi times the thumb, I would estimate to 1.5 stops, you lose or win. Depending on the situation and intended stylistic devices.

If it is the Canon, then this is so. I know of no camera in the true 1080p can Semiprofibereich. Perhaps the Panasonic? Even the professional television cameras can my knowledge, only 1080i.
Antwort von inwa:
How's that with the Halbblidern at plasma or LCD TVs? Show the fields still synonymous? As far as I know. Most can also convert to p, but this does not always bring good results. 1080p is not a prerequisite for HD ready devices, even though HD-DVD and Blu-Ray 1080p25 can. Would anyway have been better for HDTV to go to the format (movies 24p/48Hz), rather than 1080i50Hz. Through simple Bilddopplung as in the movies to get to 1080p50Hz.
Antwort von inwa:

And what is worse with the motion resolution? One can argue about it. Movies make me full of 24p and will be ok. HDTV 720 makes 50p, which is certainly better for quick movements. 50i leads to blur by so-called comb structures, as one field with the odd lines to the second field with the even lines at 1 / 50 is set included. However, when 25p fast moving objects to be blurred, because otherwise there is an annoying Strobeeffekt and the images are no longer perceived as a liquid. However, they are not perceived as blurred.
Antwort von Markus:
How's that with the half-frames for plasma or LCD TVs? Show the fields still synonymous? Hi All,
a flat screen TV (LCD / Plasma) works exclusively progressive, ie, with full images. Because television and video sales, but only to show interlaced video (50i), it must deinterlace the Television, the first picture. Thus, each flat-screen TV dominates the deinterlacing, which is at issue here especially on the quality of each instrument, how good or bad the picture looks like it. Cheap flat screen televisions and elderly are often not so great. ;-)

I have until now always clicked frames rendering, but now I'm thinking whether this is really important because the television shows it anyway again into fields. These views look at the contribution of
progressive scan quality improvement. Axel has listed in the last paragraph ( "Remember :...") but all the conditions that must be met before we can see 25p synonymous really.
Is this the case with you?
Antwort von Markus:
I know of no camera in the true 1080p can Semiprofibereich. In this thread, some specifications have been jumbled up. There are two HDV specifications with each consisting of several sub-groups.
HDV1 fol g end specifications include: 720/25p, 720/50p, 720/30p, and 720/60p
HDV2 fol g end specifications include: 1080/50i and 1080/60i
HDV1 is always progressive, always HDV2 interlaced. The different frame rates are determined by the respective television standard, which in this country (PAL) are the sub-25p, 50p and 50i of importance. At the same time it becomes clear why there is no industry in the HDV 1080p camera. ;-)

HDV1 is always progressive, always HDV2 interlaced.

At the same time it becomes clear why there is no industry in the HDV 1080p camera. ;-) Defining 1080/50i is already extremely weak-minded. The data rate is exactly the same as they would at 1080/25p. The latter has full pictures are real, not distorted in any way. An LCD television could more easily clean show as 1080/50i. A similar filter as the one that can generate two frames of two fields to create two frames with four full frames Bewegungsinterpolation. This looks destined for better.

One is a full-screen! What kind of sense does it there's a Doppler einzustezen by 2 frames obtained. If this one with 50 Hz so the eye sees happening 50p anyway no more flicker.
Antwort von Martin:
The only downside to full-screen mode is that the exposure of the camera sensitivity decreases by about 150%. If anything decreases by 50%, it is half as large. If something decreases by 100%, there's nothing left.
If something should diminish by 150%, it would be too "minus half" there.
Say: The statement is nonsense.

Antwort von Martin:

The original is 25p, not 50p. Of course you can play it, simply by issuing each frame twice. That's why I consider synonymous the 25p format for much more reasonable than 50i.
Some people, however, goes well, the motion resolution of 25p not, and who feel this need to 50i. And there was my approach, instead of four fields to be converted to four full pictures, but get 2 frames to be converted to 4 full frames.

Antwort von Uwe:
Because television and video sales, but only to show interlaced video (50i), it must deinterlace the Television, the first picture. So far I've always read that purchase more DVD's are pressed with a progressive full frames ...!?
Antwort von Udo Schröer:
Purchase DVDs are not all frames but only if it has been scanned by the film (35mm). TV on DVD productions are in the meistenens interlace images. In an attempt to reproduce these results in a progressive then Picture where the first and second field does not go together. Podium training
Antwort von wrunge:

Antwort von Axel:

Sorry, total confusion. Please enter and make it clear once and for all what happens in the output to eg a plasma screen with 25p - material. Here - as in the movies
Would anyway have been better for HDTV to go to the format (movies 24p/48Hz), rather than 1080i50Hz. Through simple Bilddopplung as in the movies to get to 1080p50Hz. Frames duplicated? This is in fact a widely - even among fellow demonstrators - unknown fact that the movies will be shown, although only 24 b / s, every picture of them but in fact twice, by a re-obstruction of the image through the wing panel. Without this mechanical trick synonymous although one would not perceive flicker, but the resolution would be a movement like the 16mm educational films, the elders still know or like amateur Super 8 films. This sounds contradictory, there's no double images included in the new motion information, but who knows the Comparison, knows that it is so.
For many, this is probably the most accurate understanding of these relationships is very important. Could someone answer the following questions so clearly again?:
1. Draws a prosumer cam (eg, XL1 / 2, DVX100) is now at 25 frames or 50 fields that are only in contrast to the Interlace method is not time-shift?
2. What do you mean in this context, 50p? Could any record Prosumercam 50p? And if so, does the 50 progressive frames, or 25 doubled?
3. What happens when a progressive output device with the offset a 50tel seconds at half-frames interlaced material? Now, please do not write only: They are interpolated. That may be. But what does that mean? Is of a lower switch to the next half frame, and thereby effectively discarded the upper (= 50%) loss of resolution? Is calculated from the upper and lower half-image, a third full, which is located
in time midway between the two? Or what?
4. What happens with full material from whatever source on a plasma when changing from one second to Use fullscreen. Dunkelpause as in the movies?
Antwort von wrunge:
Hello,
most TV movies are unfortunately not with film cameras but rotated with Betacam video cameras or something. (Please do not with all Digital Cameras Spielberg or Lucas (Episode 1) confused) Picture Only if the row was saved by line creates a full screen. TV cameras been characterized mostly on fields, this is where the problem arises when the first field contains movements and only a different image content. When attempting to create with one linedoubler reconstruct a full screen this podium. While there are intermediate devices here, but never 100% calculated. I use a tube in my home theater projector and a DVD player with progressive 50p Pal and the picture is completely calm. The sharpness that I would stop faultfinding is s.der limited Resolutionvon 576 lines. Better the picture would only be if we could have 725p or higher.
Conclusion: Certainly cinema screens to use a higher frame rate will get better too, but not the picture to show but only a fluidity tender. 24 images alone would not yield a fluid play. If you have 25p s.TV So you do not need additional pictures but only a higher frequency of 50 or 100HZ
For video cameras, I would add if possible, always in progressive mode. But should a man do not output interlaced video in full screen as it is properly understood and the said errors.
