XH-A1 Unterschied 25f und 50i

XH-A1 between 25f and 50i



Frage von HDV Berlin:
April 2007

who has rumexperimentiert times with the two modes? I have the xh-s.mal s.den fullHD Dell monitor is connected and all variants durchprobiert.
it came out amazing.

The background: I was participating with the 3 months in Africa and look at me now for the first time the footage in full HD at. after 5 minutes of pure enthusiasm, then sharpen the view and there are some things surprised me.

The most obvious problem was the rotauflösung!

saturated red color such as black before franzen from extremely coarse. sieht super scheisse out - represented on premiere on the external HDmonitor - controlled with DVI. if I then any video filters rauflege (without changing the parameters!) then the image shows fine again. well, fine maybe not, but again so much that I was satisfied.

obviously is a show at halblinie slips (yes in the red much thicker!). because the one-off and shake the filters only the red on the brightness value (Y) and her out. wow.

everything else remains unchanged. whether this ugly effect synonymous to interlace HD display (which monitors come in question since? bezahltbar?) occurs I would be interested. But since most people the movie on LCD etc. Look, this is a real problem.

whether this is synonymous in the 25f mode occurs, I wanted to know. because these modes should actually of interlace problems largely be exempted.

First I was interested in the resolution.

one could say the XH-A1 has 3 modes:

1. 50i
2. 25f
3. 25stel second 50i !!!!!!

The resolution is always different.

25f and 50i are extremely after together. technically resolution. bild gibts flicker course 25f

I found this surprising at 50i mode when I 25stel with a second exposure. yes it comes ever before. I like slowshutter rather than 18db gain ...

the resolution is in far worse case. obviously is only one field is displayed! interpolated or extremely bad ... hm.

for actually stems from the fact that I slowshutter recordings (> 50s) is only in 25f mode. because there were seconds 25stel much higher than dissolved in 50i mode.

the red fray now I'm still on the track. sign me, if I have what rausgefunden.

How to play? How gecapturet? Editing program? Sequence Settings? Words such as flickering or synonymous Jerkiness s.ehesten can not be correct to conclude settings. 90% of all 25F videos that I have ever seen are processed incorrectly. An appropriate description would be "less liquid movement representation."



Antwort von wolfgang:

No idea obs only s.der Postpro is - the description is rather on an absolute inexperience with the A1 close to the actual attitudes of many users rather than complex is described.

The preparation of the presets is not easy, and certainly not for the inexperienced beginner. With such a part of 3 months to spend in Africa, without first, just to have made notions should stop going into the eye. What of the material is recyclable, but can say remote diagnostics None (hopefully at least a part).

Sacrifice times for driving on DVI - but depends on the camcorder directly s.den full-HD, and then look at trying the O-material in order to really get an impression. Depending on your graphics card, the DVI synonymous have its pitfalls.

Why 25f at a picture flickering occur must not only understand Axel not. A less movement resolution - clear. But more signs flickering image on a different problem (possibly return to the graphics card).

To play the ready-cut material gibts synonymous with other solutions, as Grakas. Around the TViX HD, the SC200, etc.








Antwort von TheBubble:

The somewhat coarse resolution pixilated red edges IMO has nothing with the camera in particular to do this or a similar effect, I have synonymous during playback when using other video codecs as MPEG-2 can be observed. The cause lies in the Farbunterabtastung and the kind of success to play the interpolation.
