Frage von kreyco23:
Oktober 2005

Dear brethren,

I have a city built in 3d after effects. The town was created from input psd. town in which I animated a camera which this departure city. Now to my problem. In output, the camera movements are not fluid, but they jerk evenly. Bewegungsunscharfe And of course I had Frameblending activated and it synonymous with the busbar rumprobiert setting. I still have to say that I have created the project in 24 fps full screen and rendered synonymous and there is no interlaced and video material in the composition. Almählich I suspect the engine fails to render the liquid MOVEMENT darszustellen. Would be very grateful if anyone of you has some advice.

Regards

David



Antwort von Stefan:

As the video is it compressed?

Perhaps it strikes a video viewing software does not play the video smoothly.

When you come uncompressed video with larger image sizes, you easily s.The performance limits such as the hard disk controller.

Good luck

Antwort von Blackeagle123:

Hello, the problem has synonymous, but I have video files still in the process. Must be rendered differently, or are pre-rendered?

Since I am novice at the after Effexts synonymous, as you now become wahrschienlich (almost all) already know ... (Sorry for the many posts)
I'll stay tuned here:)

Many dear greetings
Constantin

nabend kreyco23,

with your concerns, it would be very helpful if you to use your system (or data and Film: Size / Format uswusf) would post here. Personally, I would guess that your system is simply too slow.

Hi All,

at 24 fps progressive is a juddering effect occurs when the movements are too fast. Could this may be a cause?



Antwort von Blackeagle123:

Hello Mark, what are progressive 24p? (Has to do with what the Field order?) Renders Adobe in such a "format" (?)...

Many dear greetings

Antwort von Markus:

Hi Constantin,

You've really got a lot of time for questions! ;-)

A progressive image sequence represents consecutive frames and dominates without question, AE (synonymous). Progressive format for the computer are, of course, since PC monitors are working as opposed to video monitors progressive. That hooked sometimes the motion: 50 fields per second (interlace -> 50i) with still look more fluid than 25 frames (progressive -> 25p).

More Info:
25p or 24p?> Progressive or interlaced film?



Antwort von Axel:

To all: I have had the same experience that a jerky 24 fps in animation created in AE, despite all the measures already mentioned in the AE edition. That alone has to do with the full images, it is not possible, because 25 ruckeln fsp NOT progressive. Would I look over an answer to this problem!



Antwort von Stefan:

The jerking may be caused by too rapid camera movement (in real terms with the 24p camera or get a virtual in AU).

At Google you can find masses of documents to search for "24p recommended panning speeds.

The book "American Cinematographer Manual" ($ 149.95 Oops!) Seems to be a standard work for 24p film-makers to be there, and probably synonymous corresponding tables (for 35mm film) are indicated.

A quote about this:
"Tim Dashwood @ http://www.dvinfo.net/conf/showthread.php?t=51185" wrote:

The focal lengths listed refer to 35mm film, so on the stock HD100 lens lets assume the equivalent s.full is about 28mm wide, and full telephoto is around 300mm.

So the chart says s.24P, to pan no more than 6.3 degrees per second s.the widest focal length, and no more than 0:58 degrees per second s.telephoto. Of course "whip pans" do not count, and shooting s.30P will give you even smoother motion than 24P.


A table specifically for the Panasonic HD Varicam there on http://www.abelcine.com/panasonic/home.shtml (Question: Why is that when I shoot s.24fps and I pan too fast, the image in the viewfinder seems to judder?). An example: 24fps with 20mm lens should take 23 seconds to pan 90 º

IMHO is at least 23s long been violently tear for a 90 ° swing, because you have to s.Riemen already.

Hello,

now I will finally answer my posting. I spent almost 2 days to find the error for the bucking to and have found him. My composition was size was 1800 x 978 (at 35mm
exposed) and I rendered the clip at 600 x 325 for viewing.
With the smaller Auspielung After Effects is not clear (to be synonymous found a reference in the reference book), the clip was just around the
Be a factor in a new Kompostion (scaled 600 x 325) to render him then at original size. Thus, the jerk was gone, and when of imaging was not a jerk eh see more.



Antwort von Stefan:

Madness!

Congratulations
The fat Stefan



Antwort von Tristan:

Hi David,

Your posting is quite old, although, for me, but still relevant. Also I have a great composition that I want to spend as flv. To reduce by half for you, but I do nested in an edition of composition with half the size. So far everything is fine. But bucking the issue remains. I missed anything?

Thanks for your reply,
Tristan
