50i in 50p umwandeln - ruckelfreie Zeitlupe

Convert 50i to 50p - smooth slow motion



Frage von serpenteye:
November 2008

Hello, I wanted to next time a short film, complete with the half-speed or even slower.
I will be recording with the FX1 in 1080i and 50i. I've already read that one of 50 fields per sec. in 50 frames can convert in the missing lines of a half dazugedichtet, so that a speed reduction is not the jerks in the video result.

And there lies my problem. How can I get done?

I use HD-Split, Premiere and AfterEffecs.

Have a look at Premiere a test video in 50 FPS instead of 25 FPS exported. In AfterEffecs were 50 different frames per sec. to see. In addition, the video, I could easily be 30% of the original slow speed, without a bucking of the image was visible. Is there something I forecast what happens in reality is not so, or you can really do? Can I at least do not imagine that it is correct?

Just an idea comes to me. I will display the same time a stopwatch abfilmen, and try, if I got the 100th of seconds on the video slow to recognize.

You can choose from 5oi by 50% iger slow motion synonymous halving of playback speed achieve, what then of course once again synonymous with 50i playing. With 50p That has little to do.
Up to 50% working in slow motion all the various sound editing programs, but every step that you are in hundredths of a stop watch so that the area can see is a totally different thing and impossible, because no more than 50 (half-) frames per second to be.
This would require the camera at least 100-200 images per second.

Even if you at least 100 (half-) frames per seconds, that would you think of a commercially available display stopwatch just blurry bar recognize the digital display. The LCD stopwatches has such a long latency period than 1 / 100 second. Experiment but quiet times and tell us what it has escaped!








Antwort von serpenteye:

That with the stopwatch was only an idea, so I take the ratio between the original recording speed and slow down the recording can be seen. So when a recording time of a sec then I would have seen 50 different frames. The 100th of the display was too slow to me is synonymous clearly seen synonymous nicely on the video. Sometimes you can see the individual 100derstel. After I use the video with only 50% of the speed of play takes a second of the stopwatch now 2 seconds. Due to the constantly changing 100th recognize, I still have 25 different frames per seconds have played. More I did not want to. Unfortunately, every 2nd frame is somewhat blurred and therefore affects the entire video slightly flickering. Whether this slight flickering on a television afterwards to see you have yet to see.

Is there another possibility, one as described above to create slow motion. Am a bit perfectionist.

Thanks again for your answers.
