25p, 50i, 60p ..häh?

25p, 50i, 60p .. Huh?



Frage von bassabus:
März 2009

Hi!

I have a very silly question understanding.

The Pal-50i is the standard, ie 25 frames / sec. Since I s.Ende at 25B / s. get out, but theoretically 50i movement phases 50 records per second, I actually 50B / s, or?

If my camera so 50i or 25p recording, the clip is on the Television in NORMAL speed.

If I 30p, 60p or 60i have the clip in mild to severe slow play, right?

Greetings and sorry:)

P is progressive
i is interlaced

Thanks for the link.

Other words: 25p material is converted to 50i material, so it s.Television properly displayed. 50i real difference: The 2 fields are from one and the same frame was built (which is why no 50Hz resolution movement takes place)

How is that for 50p? Lines are simply discarded in order to 50i to make? So yes, the motion resolution, that is synonymous a higher quality?

For Slow Motion: I Achieve a higher quality than in Premiere, if I interpret 50p as 25p (SlowMotion 2x) and then calculate the half leave?

Yes, but it stems synonymous no advantage over a direct recording 50i.

No, not because it is exactly half the spatial resolution.
In addition, in real interlace various mechanisms to the picture at all neatly presented. At Progressive, there are no such mechanisms. Can you just off the line, is not the same quality as with an interlaced recording made.

Interesting, and the would? Lowpass?



Antwort von WoWu:

For example, the individual lines during the recording with a slight blur, be unobtrusive to the interlaced to make.
The entire generation process (reading) is with other parameters, related to the entire line, tainted as a progressive reading. Taking now the parameters of a progressive reading and provides behind only her individual lines, the result may be much worse. But the other way around quite synonymous. If I take lines that interlace for a procedure and they are prepared simply to a Picture twin, the result is long synonymous not be as good as with a continuous progressive process. (Time of the temporal component apart.)
In addition to handling in the decoder since the interlace method, with 4:2:0, although the Farbsamples to 50% from the wrong lines taken from a simple doubling of a half but I halve my Chromaauflösung (in accuracy, not in Mege of the samples). So there is in the transfer of P i in a whole lot to consider.

Sounds plenty of everything mystical. Demystify this?

Antwort von WoWu:

There is nothing mystical turn.
How Chormasampling works, I think, you know.
And the consequences are described in plain text.



Antwort von bassabus:

To AS of Interlacing, I garnicht.

Normal speed playback is ensured when the recording speed, or?

So a video in on the TV at normal speed to run 50 B / s have.

To movie-tv-movies fit to convert, from a Picture 2 Halbbilider made. (Pal-Speedup times out), the playback speed is still the 25 B / s (on the motion sensing-based).

How then is 60p with a good quality slow motion produce? Or. (to understand) the 60p recording in Normalgeschwindikeit play?

Greetings and Thanks

Antwort von tommyb:

By its action with 60 frames per second recording and then this material with 25 frames per second place.

Then 30 minutes of recording just 72 minutes.
