Output formats and Slowmotion



Frage von marc242:
August 2010

Hello Forum,

I have times when one or the other understanding question:

I have a camera with which I 1080/50i (1440x1080) movies and this
then forms part premiere in such a HDV Project.
When rausrendern I now have the option above specify format
(1440x1080) to export as a Blu-Ray. But if I now my
Films on the TV reproduces, I have always felt the various
Things are not like they should be. For example, slow show
a white surface with text on it flickers, or somehow
Color transitions / gradients will not display properly.

1st Can it hang the 1440x1080 is not really standard?

2nd Should the material be properly rendered on 1280x720 for HD?

3rd "Pulling" of the material to 1920x1080 would not make sense in
since recording pixels at the missing already, these are calculated
and the Picture would rather "make blurred"?

4th Through the wrong format is synonymous Slomotion Effects of false
blurred or displayed?

Would be really nice to me because when times on the fast someone could help.

Thank you,

Marc

While I can not properly assess your problem, but the following questions I can answer you, perhaps.

1440x1080 is standard in the Blu-ray specification, available as, there's no doubt.

In principle, no, it would be feasible, of course, but it has no real added value for you, unless you produce the clip for the Web.

Quality loss because of scaling up is unlikely unless the bitrate and the codec right. In general, but the answer applies to Question 2: You have no real benefit in using a BD.

Sounds to me more like Fields reversed or something.

I think you should experiment a little with the settings in your Project and you feel small experiments with slowly forward. Take the same source material in your attempt to export and the Project. If it fails it already, then something fundamental to be broken. Afterwards you can even experiment with time-fades, and with slow motion.

Oh, what is already the way it should be? In a perfect world, our enemies driven before us through the mud and we amuse ourselves s.Wehklagen their wives, as Conan knew ;-))

"Banding" in gradients is a problem with low color depth. You generate a gradient artificially, Premiere is expected that 256 levels of brightness (actually even less, but this goes too far) are available. This usually goes just to a gentle course not look to be pixelated stage and (complex issue in the interest here
Check the Premiere timeline. When these effects there on, you have to deal with the handling of the next program. Otherwise, I'd bet on an encoding and so on an export error.



It is a standard (HDV2), and many millions have to - and synonymous with Premiere - films created perfect. The assessment should already be on the Calculator. Is it when playing the timeline no errors, you can synonymous s.Calculator the Export File check, ie, the BD. Is synonymous the error, did you play not the hardware under control. Process of elimination.



Can not we, but we must. Is not much worse than 720p. This suggests the suspicion that there was never much more. Applies to a lot of HD camcorders and next is not tragic, that you conceive.



In principle, the completely preference be no, because the playback, pixels will be supplemented after all, the latest is yes then converted to square pixels. Advantage of the 1440 File: Smaller File.



It's not a bad format. In a slow motion of course there are a few things to note. You can not go unpunished any dazuerfinden many phases, without the video at some point either jerky (no Frameblending) or smear (with Frameblending). When 50i is 1/100tel (with exposure time) a totally clean double slow motion possible. Intermediate values are usually a bit messy. For very fast moving action (hummingbirds, apple falls from the tree, ax cuts off the head) is good because of the inevitable motion blur and by far too few stages of postproduction no-slow motion. Then it must be a high-speed camera.

@ Pailes & axel

Thank you for your detailed responses.
This brings me, in fact, all steps next.
