Infoseite // Field-recordings or full screen?



Frage von ssalbach:


Hello,
I want to achieve the best possible quality with my SonyVX2100E.
When I mount the camera on a tripod and moved them to recording objects, such as people at work,
I choose to be better half or full images for this camera.
I Versthe it right that she creates in this mode only 15 frames / sec?
So you should probably take half images? right?
Or how, or what

Antwort von wrunge:

Can this camera for progressive recording? To my knowledge, no. And 15 pictures are anyway too low to get a smooth movie.

Right ;-)

Antwort von wrunge:

If your camera capable of 25 frames (progressive is to be incorporated), then you should use it. Draw your Camera, however, only 50 fields (such as the DCR-VX on 1000e), you should not try to edit it later as a full screen image as this leads to error, since each first and second Halbild not identical.

I watched some time ago once the data from the Camera and I to remember that it only captures half frames, but Perfect!

Antwort von Wolfgang Schuch:

A full recording dubbing makes sense only for DVD or to film ...
For viewing on a television (ie, to play the DV tapes via the analogue CVBS - or SVHS is output) of the interlaced mode is appropriate and smoother images.
This is especially noticeable when scrolling texts ...
for the eye only takes about 25/sec sequences perceived as "smooth" movement.

But that is formulated somewhat misleading. If I put a DVD-PAL-progressive film look on a similar display, I see a de facto synonymous "only" 25 frames per second, where the refresh rate is 50Hz, although but a single picture for each of 1/25s is shown (ie almost two times in succession). But we can not exactly say that the movies film transfers have no "smooth" movements would be. For me, the whole looks very fluid.

But I agree, of course, that progressive playback on a completely working with interlaced tube makes no sense (and vice versa).

Christian

PS: This de-interlacing issue is really full right now but in fashion.

Antwort von Wolfgang Schuch:

Comparisons times a fast-moving writing in both modes ...
Since the interlaced playback is smooth over than 25 / sec full screen.

For the visual perception synonymous plays the Resolution (screen / kl. Monitor) a crucial role ... for the impression of movement is created not only by the technology, he enteht "in the head of the spectator."

Antwort von Udo Schröer:

Hello,
With 25 frames per second you can not get a fluid image sequence nor in s.TV. Movies
1. Cinemas play their film with 24 / s is s.jedes frame of a wing panel, however, about 2x interrupted resulting in a higher frequency. Result: We see each of the 24Bilder 2x yields between 48 frames per second.
2. Interlaced video will play in 25 fields, depending on the first then the second is 25 frames, with the change seen it fluently dangled from the eye because it had seen 50 pictures.
3. Progressive videos with 25 / s play, but with 50Hz, ie each frame twice erscheibt resulting in sec 50 pictures.

The best quality is achieved with a more progressive scanning, only the subsequent deinterlace makes little sense since the image content of the first and second field are different.

I would always burn a full screen if possible on DVD.

Now again for Dork:

- I got as the GS 400, with 25 frames / s can accommodate. When such a clip, I burn to DVD + Play Progressive s.TV (50Hz), they appear 25 frames so 2x + motion sequences are represented as fluid as the LCD of the CC?

- How is this now a TV with 100 hz? The individual frames are then displayed 4x, thus still liquid?

- Or how it is on my computer monitor (LCD)? Hab grad mal checked - which has a default setting of 60 Hz? Should I increase to 100 Hz?

Antwort von Udo Schröer:

You can burn the DVD Progressive without problems. All DVD movies that were Abgetatet from 35mm film containing a Progressive Picture.
1st TV set 50HZ without progressive scan, the picture is in the DVD player via S-video eg car broken into Pal. Field A and Field Picture B is played in a second for each 25 X. Whereas in this case, the content of A + B is the same. With Interlace Picture A + B is different, therefore, arise s.bewegten images the podium.

2nd TV Sets with 100 Hz can not be more pictures again, but repeat the fields more often. Depending on the type Field AABB or ABAB in this sequence, each 25X returns 100 fields / sec (100Hz) (Do not forget AA or BB together and you get 1 full picture)

3. TV devices with Pal Progressive 100Hz give each frame 2 X AA or BB again in one second, 50 images (frames shown).

4. PC Monitors have always been a Progressive Picture, if it does not exist on the medium is calculated to have the PC one, here it comes When interlaced video podium as Field A and B different image content.

The interlaced video is indeed emerged as one not in a position to broadcast 50 frames on antenna. So we have divided it into fields and each are transmitted alternately at 50 to 25X images. Here, indeed, the problem arises.
You Would a Stillimage in interlace reflect on a TV, it would complement the first and second in a Picture. You would hardly see any difference to progressive. If, however, movement into the game as it comes to image errors due to the different image content.

I do not know exactly the GS400, but I have to remember that this full-screen mode, no "right" is full-screen recording. The camera probably does nothing other than the half-images recorded in the original image de-interlace, therefore, to calculate a combined picture to this store and then to tape. That's obviously not the kind of full-screen recording, which one usually connects with the concept of progressive scan. Under these circumstances, I would still tend to record interlaced. Always following the motto ... not herumkurieren s.Symptom.

@ Chrisgau

However, the GS 400 can accommodate with pure 25 fps.

Again, the question is: I am here now had a better (more fluid) representation, if I had taken up with 25 fps progressive + are put on DVD, or record would you prefer interlaced DV-AVI + author ...?

Here, too, again the same question as at 1

Quote: 3. TV devices with Pal Progressive 100Hz give each frame 2 X AA or BB again in one second, 50 images (frames shown).

Sorry that I still have not fully understood. What is now the difference to 1 With full-screen images? Here you write so synonymous "Field A and Field Picture B is played in a second for each 25 X" => also synonymous each 2x full-screen ...!?

Quote: 4. PC Monitors have always been a Progressive Picture, if it does not exist on the medium is calculated to have the PC one, here it comes When interlaced video podium as Field A and B different image content.

Yes, already clear. But it's better now, if I monitor settings to 100 Hz, instead of as now at 60 Hz (for the reproduction of) videos?

Antwort von Udo Schröer:

Hello Uwe,
you add the times before: You take one Stillimage and cut the same in 576 strips. Now you go forth and removing every other strip. What remains is a half frame. The strips that you have removed form the second field. Now what is the best Picture? Of course, what is not cut. This is progressive scan (full screen) This is the chopped-interlace video (TV Television)

At 50Hz TV, these fields as shown in the said exchange, the fields created by changing the flicker. Remove (interlaced) to flicker around this has been developed by the TV's 100Hz frame rate so fast that your eyes do not see the interlacing.

If you now to the above Stillimage a second would have, had taken place where a small change that would not allow the fields of the first with the second mix, as in the range of movements the stripes (lines) do not match.

Such aberrations can be avoided with Progressive Scan and no more. On playback, the picture but looks as Homogeneous absent from the interlaced. This is easily visible!

In which setting gives your PC the best picture you have to try out for a rich smooth playback on a PC like s.TV 50 Hz.

I hope you could I hereby inform you reply would be nice.

Antwort von Uwe:

Hi Udo,

I find it really nice that you so patiently answer, but somehow I have the feeling that you are my specific questions partly not really answering.

So, I'm me now so zusammengfriemelt (info + of you still synonymous with information obtained from the web)

1. Opportunity: Date = 25 frames> on tube 50Hz => images are interlaced, A + B = 1 frame. ==> No advantage prev. AVI interlaced most (if only for PC playback is done)

2. Opportunity: Date = 25 frames> on tube 100Hz => images are interlaced AA + BB = 1 frame. ==> Again, no advantage prev. AVI-interlaced

3. Opportunity: Date = 25 frames> on Progressive Scan
50Hz (2x25) => A + A full-screen full-screen + B + B-fullscreen
100Hz (4x25) => 4x the same picture
==> Should definitely have advantages, if previously has been gradually incorporated with full ...

Antwort von Udo Schröer:

Hi, up correctly to point 3 of everything. In Picture B (full screen) is already at the next picture of your movie, and each is represented only 2X So 50Hz. In this presentation you will not need any more 100Hz, since there is no interlace flicker is no longer synonymous, and therefore.

Antwort von Udo Schröer:

The double repetition of every image in the P mode, you can compare well with the wing panel of a cinema projector is not visible when stopped for a brief moment the Picture.

Antwort von Uwe:

Yes, thank you very much for your help, Udo. I came up with the 100Hz progressive scan on this Page:
http://www.dvd-tipps-tricks.de/index.php?url=http% 3A / / www.dvd-tipps-tricks.de/main/info-bildformate.php

It is stated in progressive scan for the expert
"With the advancements transferred to a quasi Progressive digital image signal to open up entirely new possibilities. The preparation of the image data could then be held in the playback device, for example, and one for PAL 576p25 image signal of each Picture 2 (= 50Hz) 3 (= 75Hz) or 4 (= may constitute 100Hz) times. "

But the 100-Hz progressive scan are then in the future, perhaps even music ...

Antwort von Udo Schröer:

Nice to hear,

I use a tube in my home theater projector 25p 50Hz and the picture is good. That's been going become synonymous with synonymous 3Bilder sec 75Hz I do not know. Be glad that you can take progressive. I can not stop the predecessor of the 1000s only interlaced.
