Sony kann in die Vergangenheit filmen! (in Zeitlupe!)

Can Sony in the past on film! (in slow motion!)



Frage von actaion:
April 2009

To my amazement I have with my respect SonyDVD510E slow recording of the option is found, the device so that the recording has a slow motion 3 seconds before adding the Rev button pressing starts.

You can with the actual device by pressing the recording button, the last three, already last seconds!

That is but the cam seems to continuously incoming images erstmal all stores, right?

How does it work at all with the slow motion?
The speed is 1 / 4 reduced (3sec -> 12sek). If the Cam at the time that is actually 100b / s?

The quality is unfortunately poor, the Resolutionsinkt (tripping output remains the same). When bad light will also darken the picture and gray. The movement of liquid but still.

So times I would be interested in:
1) what exactly does the Cam in slow mode?
2) why does it only 3 sec. long?
3) you can with software from a normal host a similarly good quality slow to reach?
4) there are other cams of the price range under 500 ¬, the slow motion can be better?



Antwort von Axel:

A Camera, which interlace recording, has 50 movement phases per second preserves. It was always possible for an impeccable double slow motion to create. For 25p anyway. A double from 25p slow motion on the other hand, is already extremely jerky. This will, however, bucking regularly in films used to emphasize movement. It does not work in the John Woo aesthetics, but it looks good, taste.

Software, the movement of a few phases creamy slow motion makes so completely intermediate phases interpolate, it is rare. After Effects example



Antwort von Jan:

Hello,

Sony calls the feature "Smooth Slow Record". Here are 200 pictures per second, which with a Resolutionvon about 640x480. Some FX models, it takes only 6 seconds.

This feature, almost all Sony CMOS cameras in recent years. Why CMOS? Because you are this type of sensor can read faster than a CCD. At least it is in the consumer class so.

Canon, JVC and Panasonic ignore this feature. Samsung HD synonymous models have a very similar function, then even 10 seconds long (not 9, not 11, but always 10 sec).


You may not assign the same function but not with zb Panasonics Pre confused record, which record the last 3 seconds at normal quality with no slow motion on. Prior to the operation but must be activated. Pre record but is bound s.bestimmte settings (duration & Modiwechsel).

Casio is currently the "Zeilupenkönig" consumer class, the EX F 1, FH 20, or the new FS 10 & FC 100th The two new models shine synonymous with new features such as wild Dynamic Photo (Slashcam introduced this feature a few weeks before). You can even own moving images in a different background will be placed (eg Du spazierst on the moon).

So a normal cam, but with Corder makes interlace, right? So have my record 50i?
But does Jerkiness synonymous four slow motion not.

Then it was so good that I have for the Sony, and not for a Panasonic chose ;-)

Hmm, one would have from 200 B / s not even 8-fold slow motion can make?
And why will reduce the Resolutionauf 640x480?
And why synonymous light sensitivity? Because the belichtunsgzeiten be shorter? or are there other reasons?



Antwort von Jan:

Is a question of extremely fast read memory (there is the slow motion is often recorded, and later on cassette, or flash memory & hard drive letters), Processor and sensor. From the basic right highspeed cameras cost a fortune synonymous.

The Resolutionsinkt halt because of the extremely expensive components required for a full HD slow motion with longer duration and more frames / sec would be required.


Yes, like in Casio's high-speed functions is a very fast shutter speed is used, you hear of even faster than 1 / 10000 sec, so you need plenty of light for the recording.


From Sony's SSR we learn very little, just 200 B / sec, 3 sec, or 6 long, ca VGA quality. These images are then stretched on tape, flash memory or hard drive is written. Even in internal Sony documents is no longer. Casio is going closer to the function.

Antwort von Videofactory:

For real high-speed cameras to take several floodlights on what to see.

Is synonymous clearly yes, because if I have 200 pictures in one second time, the shutter thus synonymous as fast or faster.

PS: Yeah, I recently interrogated me or is there really a camera, to 1,000,000 frames per second record?

Gruß, Alex.

PPS: The title reminds me somehow s.Déjá Vu - race against time.

Clear. The bucking refers to the phase ratio in real time, with the 16 phases / s as an absolute lower limit for a semi-liquid as perceived movement. Stretches these (synonymous or not much better 24/25 B / s), the Jerkiness strengthened. At 30, 50, 60 or even more stages can be arbitrarily stretch without a Ruckeleffekt occurs. A little exaggerated, because what I wrote, but at 50 is a slow motion, at least fourfold synonymous nor unproblematic.

According to at least the Sony Can Z5 SSR synonymous in HDV and DVCam, not only in VGA ... because someone has experience with, or agree with the facts, where the Sony requires?

Saturday Fastcam the models are their flagship products ;-) You mean the SA5 ;-)



Antwort von Jan:

With SSR, I thought the "Smooth Slow Record" that is the slow motion function for CMOS models of Sony. This function is almost exclusively in the consumer models.

Precisely because they do not bring much, at least not for a professional.

In specific dealer brochures will be synonymous to Resolutionvon 640x480 indicated. Until FX 7 is it definitely a Resolutionvon 640x480. Although it would be funny if Sonydiese function in a better camera under the same name with any other data would equip - but perhaps it is in the Z Pro models.

Yes, actaion, you were right, you can at Sony's pre-SSR choose whether 3 sec before or after recording. I had already forgotten, probably because the function was tested only once (is not).

The new SonyXR 520 are synonymous seconds from 3 to 12 sec hard drive written.

Yes, and exactly this Sonyfür SSR is synonymous in the Z5 HDV specified.
So much about the 640px ... gaukeln there or what?



Antwort von Jan:

Will probably agree.

I know of holding this function only for the consumer models and the 7th FX

Antwort von crazy-spy:

Yesterday evening and just a few tests done with the Z5 ...

After the results of yesterday evening (fun fair atmosphere, therefore, quite dark, lots of neon / tungsten, Stroboscopes) in slow-motion function is not satisfactory, I have the whole gera nochmnal with a little more light made.

My subjective feeling: The Best Picture can be reached with his increased shutter of around 1000 and its Middle Aperture to 4,8-5,6.
The recording of the whole is in 1440x1080i, ists of the picture quality, though not as high as in normal mode, but for certain images are very useful as I do. Stop as of Sonyangegeben reduced, but perfectly usable.

Software, I then have the test done, as the images at 50% speed look, that is, a slow motion again increased. Also very nice results - useful for me!

That should be just a small, subjective impression of me his.
I film a lot in the field of sport, so for me this Funiktion very ideal. The disadvantages, such as the blockade of the camera for recording time and the increased volume, I need to be manageable.



Antwort von Jan:

Thank you for the test.

I have this function in the prosumer and professional equipment has not yet viewed - for me is a Z 5 unfortunately too expensive ....

Antwort von crazy-spy:

Another tip:

The longer the slow uptake, the worse the quality.
Also: 3 seconds and be happy.

As this example with the FX1000 does not work, you can change the default 6 seconds prematurely abort - the quality should be better then what - then at least the first test of spontaneous to a friend.



Antwort von actaion:

so, hab now synonymous times a small application (Kubb) for the slow motion is found. Who likes, look here to DuRöhre:


PS If in hindsight again slowed by 50%, ie a total of 8-times-slow motion.
