Infoseite // Question about motion blur when shooting



Frage von sahamFriend:


Hello,
I recently had the Canon HF 100 tried and found that it is unsaleable, because the motion blur is very significant.
If a child in the living room of a corner to the other runs, it is totally blurred and thus the recordings unusable.

In another post I have here in the forum to listen to get that motion blur and AVCHD always belong together.

Now again the question about recording in FullHD:
1: FullHD AVCHD and is always strong motion blur?

2: FullHD and record to HDD or tape makes a difference in terms of motion blur?

3: Or is the problem of motion blur, the speed of the auto?

Greetings from the north

Antwort von Debonnaire:

What did because Bewegungsunschräfe and marketability of a camera to do with one another?

The motion blur alone and depends solely on how fast (how many pixels on the recording chip) is a filmed object recorded on each frame moves!

Two factors are of importance:
1. Angular velocity of the object before the lens.
2. Exposure time of each frame.

Typically, and in the default configuration is a video frame (at 25 frames per second and, usually, interlaced mode (ie 50 fields per second)) with a narrow exposed 50stel seconds. This can be done but, for various reasons, cameras synonymous in many different settings. If the exposure time is shorter, the (same) objects with less motion blur displayed. Prolonged exposure time according bewegungsunschärfer.

You have to be so easy times the settings of your camera and control the exposure time is correct, if necessary.

Hi,
if a child can not be sharp on film, of if it runs right to left, then a unmerchantable Cam! ME

Then just what motion blur with shutter speed and fps to do?

And not, as here in the forum asserted otherwise with AVCHD?

Will not the decisive role in the motion blur to play. The main problem lies in the individual assessment in the NLE, where, in complete disregard of the cinematic requirements of just a single frame analysis.
The motion blur is the film for effect but crucially, the fast-moving object may simply not be sharp.
It could be the exposure time is shortened so far that the object is synonymous in the frame is sharp, but then had a unfilmisch choppy stoboskopartig lit movement, the object almost clatters across the screen, so simply impossible.
The degree of fuzziness is synonymous way, our brain information about how fast the object is in its angular velocity has moved.
For short exposure times, this information away, so it is only a fraction of the reality recorded at 50 fps. At 1 / 1000 sec exposure time, therefore only the twentieth part of the real motion sequence.

Since I am, in this context, absolutely do not agree! He has written: Quote: ... and found that it is unsaleable, because the motion blur is very significant.
This is obviously a fundamental intention that the camera actually want to sell, but do not believe this, because the camera seems to just have a major flaw is the huge motion blur!

And not: "The Camera is in no case to sell, because it such a huge toll has motion blur!"

Regarding the mention of the entire (potentially bad) vendible camera but even with the question of the Asker's has to do is unclear to me, however, cryptic ...

Antwort von Axel:

I think the thread starter is outraged that a blur because of alleged allegedly defective product from the bona fide purchaser and returned by the seller to refund the purchase price should be withdrawn. He probably does not consider it Ficedult or to offer you. "Unsaleable" I understand as "with this deficiency is useless and should therefore not be sold at a price that is Height a usable product promises." Not that it's not the malice of the dealer, provided s.Ahnungslose could be sold, but on moral grounds should not.

Antwort von B.DeKid:

Hi sahamFriend

So AVHCD is different / more Kompremiert.

Blur of movement or likely in your case, bucking, comes mostly from the poor lighting and the function of the Car Camera s.Einsatz place. In the supermarket example, the child is filmed as a CameraLink because of the rather bad light with happy times down the exposure time / shutter
What then leads to bucking. Test times the camera outdoors in the good business you give you a Camera synonymous with times to test out.
Desweiternen is always moving distance to the object and the used synonymous Optics crucial. Focal length (zoom) is responsible for the movement almost fatal.

The Canon HF series is with the GM number to compare what the quality is concerned.

I think it right to a good camera is.

Actually, is about motion blur.
In the supermarket but surely this is even more than outdoors in the other there but more sharpness at the same time frame more Jerkiness lead.
The automatic program of Consumer cameras work in general as follows: in low light is the aperture open, the exposure time at 1 / 50 ev and automatic gain added.
With increasing light is often trying to Aperture long as long as possible to roughly 4 to hold. The first one is by shortening the exposure time to about 1 / 100 and also by inserting a variable Graufilters still in constant aperture.
Only then there is another (bad) reduction in aperture and shutter speed to further reductions.

Antwort von Debonnaire:

What brings ye ne for nonsense discussion about shortening the exposure time? And above, then the exposure time / shutter DOWN "? It works exactly the opposite! If the exposure time is longer (or is UP), THEN take the motion blur! If you have so much light that you run a Graufilter alignment should, then you will be guaranteed no problem with the exposure time to get renewed (and thus with increasing motion blur), but, if anything, the exposure time is shorter and thus the sharper movements!

Space


Antwort von domain:

So I wanted to be brutal as DeKid not say, but you just repeat my statement.
However, your last sentence "... if anything, the exposure time is shorter and thus the sharper movements," the general understanding should be changed: "If anything, the exposure time is shorter and thus the frames in the motion sharper." (but especially at 25 fps to stronger Jerkiness can lead).
And another thing, it goes without Graufilter in Videography is not just that those in consumer cameras, as opposed to professional cameras are auto eingeschwenkt.

Hello Wolfgang,

You can quick your definition of "stronger Compression" People?

Thank you

Antwort von WoWu:

For higher coding efficiency, the image quality decreasing data obtained at higher compression, however, takes the picture down from the increased compression.

The procedure is no different.
It is based, like MPEG2, on local and temporal Prädiktionstechniken in conjunction with a transform coding of the Prädiktionsfehlers.

The distinguishing feature lies in a higher quality image, so the transmitted residual image error is accordingly low and thus a lower transmission rate show.

For higher coding efficiency is synonymous with the image quality of the data from only comparatively less than with lower coding efficiency.
While lossy compression will depend among other things, the image quality of the data from.
The data behaves inversely to Compression.

Antwort von Axel:

To these facts times in everyday language to translate and while on the topic of the thread to refer:

1. The AVCHD camcorder works with a codec that is superior to Mpeg2.
2. The maximum data rate is 17 Mbit / s, very good for AVCHD.

Question behind this addition to discussion: Is motion blur a compression artifact?

The many think. At lower data rate should be the motion blur bigger. This can be obtained by coding a video with a lot of movement in the H.264 codec test: This is not so. The Picture is only a total of muddy, so the motion blur synonymous.

Counter test: same recording with a shorter shutter: Each phase of the motif is displayed sharp, despite the Inter-frame compression.

Conclusion: Not every recording, the "something" on tape records, is worth it. "More Light" (Goethe).

Space


Antwort von WoWu:

@ Meggen

Your argument is absolutely true ... NULL data for each picture is bad, no preference how efficiently it was encoded, but then the curve is different and must always be compared to either an identical (optical) image or the image of the same data rate.
The result is efficiency.
It is simply not to say:
Lower data rate = higher compression = poorer quality. That I had meant. Many did, but just do not understand what actually is transferred to MPEG and more confused with this picture contents and then say: the less the more data has been omitted from the picture, that is, less image content, that is worse picture. And this is of course quadratic nonsense.

@ Axel
Due to the significantly higher resolution of H.264 is of course synonymous unheimlich many motion vectors, in the course of processing and representation behind a higher requirement synonymous s.die speed of the LEDs are. Motion blur arises in no small part synonymous here, therefore, was Jan's issue of the representation already hit the mark.
But to-1) times, we avoid the word "superior" to not immediately turn up account verses, but it is precisely what motion is concerned, significantly more powerful, because it flows into finer steps can resolve.
At 2) A possible data rate in (AVC) at 17 Mbps is not limited but may be up nearly 1 Gbit / s go.
Companies that use AVCHD appears to have a limit of 24 Mbit / s made, but for all non-professional applications to be quite sufficient.

Otherwise, absolutely no motion blur compression artifact but rather a question of speed readout. But, ever faster (blurred) something is, the more will the subsequent encoder to stress and can be moved within the time window may not carry out the process and stops. Result: The macro blocks are visible in the picture. (In addition, of course (as mentioned above) the quantities s.Bewegungsvektoren.
H.264, on the other hand again, but a tool, the edges of the macroblocks as "cleared" to make them invisible (it) to make. Result: slight fuzziness of the whole Bides, as has been correctly observed.
On the other hand, helps only a correspondingly efficient computing power (not just more CPU).
Also transcoding, especially in an environment DWT lead to such obscurities. You have such observations so be careful how you deal with the codec is.

Now we have no information, how quickly the child because the room is gone, but each of us knows that motion blur, as soon as you Stroboskopeffekt not want to have, in fact, a similar phenomenon (see film). That is in the digital area in all stages and continues through some other added effects, increased.
This is not a problem specific AVC. Wavelet reacts as significantly more dramatic.

However, ... and here we are now with one exception, the AVCHD specifically could lead to:
With AVCHD, there are elongated pixels (1440), which is in HD does not exist may.
But this must of course play around and must interpolate ... with the known artifacts.
Therefore just synonymous Jans question after playing ... My first tip is synonymous in this direction. (Without knowing the Picture).

Antwort von Jan:

The asker did not respond to my question.

Certainly a small representation of a motion blur HF 100 is already possible, I will not even deny that. Was not it 25 P program, or the shutter and when shorter than 1/25sek =?

Often it is much more s.einem player & program which important information about the AVCHD specification is missing, or once again mark old LCD Television HD Ready or not 100 Hz, sometimes synonymous halt a poorly equipped Calculator or missing driver software.

I would answer the questions as:

1. No, if you have "strong" mean, is strong, but relatively.

2. Some users in the video are meeting even believe that HDV (ie cassette) higher has motion blur. This should actually WoWu confirm. Ich hab da mal Panasonic AVCHD leaflets read, as with the AVCHD encoded images, there was improvement of! spoken to other standard - it was about the movement representation.

3. Definitely not with the HF 100, I did so often with her sharp jumps, they responded very quickly to different distances, synonymous, thanks to its two sensors.

I feel the HF 100 images s.einen well-equipped computer with a good player like VLC to be very good, synonymous s.einen 100 Hz LCD or plasma television is the HF 100 Picture is very good, if a person is synonymous with the picture is (I my running - not in short distance running).

From my experience in the company or here is often something else behind it, or you're a very petty customer.

And again AVCHD represents nearly all MPEG-2 variants in the shadows, working more efficiently with less data volume is currently very difficult to avoid, at least in the consumer class. WoWu is in the area but the professional.

Antwort von domain:

In the last few hours (but not because of this thread here) I have made some attempts to demonstrate the importance of motion blur when panning etc..
It handeltete it is the following problem: Sometimes I make shots in the NLE in the vertical direction on pasted portrait photos. First, here is the picture at the bottom of breastfeeding for 1-2 seconds, then begins a buttery soft bezierkurvengesteuert gradually increasing accelerating ride in the upper area, until the last picture again after slowing down for a few moments is very quiet, so everything about 10 seconds settled.
What particularly bothered me was the picture bucking or stuttering at the sharp s.sich Still Image s.einer some Kamerafahrgeschwindigkeit.
First, the upward swing still quite good, but then it is really disgusting smoothly until you return to the smaller velocities comes.
So what do?
The solution was to create a keyframegesteuerten also increasing vertical blur on the picture to place and although there s.meisten where Kamerafahrgeschwindigkeit is synonymous s.höchsten.
And lo and behold, now is the normal case, where the frames in the middle of a significant, but only vertical blurring of contours which.
So if the evidence is not ....

Time, quite apart from that I am with your assessment completely go, I would be described your interest in trying times. Do you have a chance download it somehow to make?

Space


Antwort von Axel:

Your test shows so synonymous that the motion blur is proportional to acceleration. This means that there are not sufficient, then the bucking motion. But there are a disproportionate synonymous. In After Effects you can auto add Motion Blur. But are synonymous with the limits: With a frame rate of 25 fps or below certain swing speeds - mean that - not smooth possible. When panning or motion pictures, there is no organically flowing contours, as in life. The position change of frame to frame are therefore clearly perceived. The same applies synonymous for 50i/50p, only less severe.

Your claim from a neighboring thread, 25 phases per second would 1/50tel Shutterzeit always half of the truncated tail movement, and therefore would be bucking the images, sounds logical at first. Why should a video circulating the principle of aperture an analog film camera must be repeated (only in relation to the exposure time reached Bewegungsunschärfe of course)? There is no video in the dark phase, ie have the appropriate exposure time 1/25tel seconds. This confused me rather, because it contradicts any practical experience that 1/50tel seconds really the only viable Shutterzeit is. Perhaps someone may know the background so incidentally?

Space


Antwort von domain:

Quite correctly, the motion blur in Liquid, I had almost forgotten, goes on 3 parameters (angle, length and starting angle and independent set of animation keyframes, or layers).
Will some experiments described in comparison to manual method and then make again report.

The theoretically correct exposure time for video is always 1/fps, eg 1 / 50 at 50i, or 1 / 25 at 25p.
But I have to admit that I have to halve this exposure time is often applying synonymous. It is somewhat a compromise that is still viable.
In principle, however, the years since the existing misunderstanding of the correct exposure time in connection with motion blur, although I do believe that this is a problem in 50p or more, no such role to play.

Well hopefully we get this increased awareness of the necessity or the beauty of motion blur "sharpened".

But I am already anxious to know when the next post with the content coming: strange, I now have a so-expensive camera bought and are still moving things that totally blurred.

From "experts" tell us then also regularly that this with the image compression may have to do.
What I had recently read, however, not entirely true: in AVCHD, the whole picture and not just moving a bit muddy and there is in mpeg2 predominantly blocky education. True, I have often observed synonymous, but it has motion blur with the strict sense most times nothing at all to do.

One final word relating to "Compression, compression artefacts and (presumed) resulting motion blur":
During the compression of video images (no preference whether MPEG2, MPEG4, AVCHD, H.264, etc.) will be tried, the same as just a time to save Sichveränderndes simultaneously and accurately as possible but minimal memory recorded. This means that in static shots rather blocky (the professional says, compression artifacts) may occur, as in moving sequences. The latter are less compressed than the former and thus appear in better, ie closer s.Original lying, quality on the monitor. That is to say, but, conversely, that just by Compression exactly NO additional motion blur is introduced. This applies in particular to a 2-pass encoding with variable bitrate, where exactly this time-look-where-I-while-encode-static-parts-picture freeze-and-where-I-moving-parts-picture-better-dissolve must be carried out very efficiently!
