Frage von Grappa:
Hi,
I'm from the photo corner and would like to use my 5D II now synonymous times for movies. I know that can be set by Firmewareupdates additional frame rates, just me is the sense of still elusive. My question therefore: Is there a good overview of the topic that framerate should I set when?
Thanks
Grappa

Antwort von WoWu:
It depends what you want to do after that.
Do you consider it only s.Computer, it's pretty no preference which image formats (and timing) you choose.
Do you want it but afterwards, for example, a Blu-ray burn, the choice is already close. Likewise, if you want to sell it zBsFernsehanstalten ...
An image format (and the associated timing) is chosen so s.besten based on the target application.
Antwort von B.DeKid:
30 fps = NTSC (Video for INet or partly synonymous with fast objects)
25 fps = PAL (standard for all really)
24 fps = BluRay Movies or standard in almost all film productions
D film in the country with 25fps and shutter 1 / 50 s.meisten makes sense.

Antwort von masterseb:
available here in the forum certainly abound, but soon all over:
24p - film look (theater / computer)
25p - European PAL standard (TV - 50Hz, DVD)
29.97 - usa NTSC standard (TV - 59Hz, DVD)
30p - almost standard NTSC (or 60Hz)
everything about it -> slow motion
all of which -> time lapse
all these values can be used synonymous style, regardless of the end users. keep in mind: the shutter with min. always the market value of twice the frame-value (eg. at 25fps, the shutter in. 1 / 50)
s.besten you go with 25 which is s.flexibelsten that can be adjusted in both directions and does the film look (motion blur in this case) very close, it can still be used immediately without conversion to a dvd.

It went so fast, thanks for the replies! :-)

the shutter with min. always the market value of twice the frame-value (eg. at 25fps, the shutter in. 1 / 50) No. The shutter speed can not exceed 1 / 25 at 25FPS be - there is no minimum value for the border. The shorter the shutter speed is, the strobe strength, movements.

Antwort von masterseb:
semantics. minimum / maximum is pure interpretation. and no, 1 / 25 for fluid movements too little. which is especially noticeable in pan shots.
Antwort von deti:
semantics. minimum / maximum is pure interpretation. and no, 1 / 25 for fluid movements too little. which is especially noticeable in pan shots. Then you did not understand something. The usual representation of the shutter speed as a fraction results in smaller values, ie, shorter times at larger divisor (which is the value below the fold).
In this respect, you reach the maximum range of motion blur, if the exposure of the image, the maximum time available. With a frame rate of 25FPS, therefore, the maximum exposure time 1/25s = 0.04s, ie 40ms.
Is illuminated with 1/50s, so the exposure time is reduced to 20ms, which is only just half the time exposed and movements that take place in the second phase of 20ms, no longer be added to the image content. Thus, the next picture starts at a later time, leading to a jump in the movement. This effect is stronger, is the shorter the exposure time selected, or greater than the divisor. Do you understand?

Antwort von masterseb:
images are sharper with a smaller shutter and motion information have more, less motion blur. this is experimentally verifiable. None is working with 1 / 25 at 25frames. it is always taken twice in the practice. reckon there need me.
Antwort von WoWu:
None is working with 1 / 25 at 25frames Yes.
Antwort von pilskopf:
But the usual is not. Finds synonymous but not so bad, earlier have all my home movies with 1 / 25 rotated. : D Did I just liked it better than with 1 / 50.
Antwort von WoWu:
1 / 50 does have disadvantages, such as Deti has already run for half the exposure time (at progressive recordings) and sharper the images are no more (as a direct function).
Antwort von pilskopf:
I was really pleasantly surprised at the Gh2 of 1 / 25 because the 50i HDV footage and is somehow not really bad or looks and jerky, but at 24p looks great from the right. Why is this in 50i material but as useless or am I the imaginary or made her different experience?
Antwort von WoWu:
Interlaced is otherwise exposed. Because the integration takes place each half-image are 40 over the full ms.
HDV is the way synonymous wonderful, you just have to just use a camera that records synonymous natively progressive.
Antwort von domain:
1 / 25 shutter at 50i / p not going to work because it can be read in CMOS but overlapping (with strange effects), but when CCD was previously impossible.
Rule of thumb: Shutter speed is the same 1/Framerate. In all other cases, eg at 1 / 100 at 50p or 50i, you lose 50% of the possible image information.
Antwort von WoWu:
For interlaced, it is the way synonymous still in it, whether you are a 1-chip or 3 chip has camera because with color mosaic mask, this means that a first at an intermediate image on a center such as a green pixel incident light beam at a second intermediate image not to the center of a green pixel in the neighborhood of this incident are other green pixel.
The light beam can either strike between the centers of pixels, or synonymous to the center of a pixel of a different spectral sensitivity, in the example mentioned for example in the center of a red or blue pixels.
The color component of the detail is therefore not shown in full color and the contour and the contrast becomes weaker. Unlike the case behaves in a 3-chip camera, since the relevant details on each case again and learn the proper filtering identical to the first field.
Such are the subtleties of such primitive methods from the black and white world.
Antwort von iMac27_edmedia:
at p25 with 1 / 25 has motion blur during fast movements and are then ideal as a jerk at 1 / 50, with 1 / 25 man synonymous has a lot more light available, which often synonymous DoF looks even better.
