why Jerkiness pan / zoom in H.264 transport stream?
Frage von Jochen Kremer: Juli 2020
Halli Hallo,
a while ago hab 'ich mir some HD Streams of Oneness Festival saved (DVB-S, DVB-Viewer) - if so good.
However, the playback (WinXP, Media Player Classic 6.4.9.0, CyberLink H.264/AVC Decoder 7.x) somehow unsatisfying. Pans or Zoom basically bucking and regularly. Lack of computational power I concur, as the utilization of CPUs well below 20%.
Kann mir da jemand clues mention where the bucking and comes as I can stop it?
(With the subtleties of the MPC about the Filters-/Dekodereinstellungen etc. I prefer not familiar.)
Greetings! Jochen

The material was certainly a frame rate of 25 Hz or 50 And thou hast it probably has a normal TFT monitor sees. The Dinger typically run with 60Hz. Without extremely rechenzeitaufwendige Frame rate conversion is bucking inevitably, because the Frame rates of Film and playback device in any integer Relationship.
Some TFTs can be synonymous with 75Hz operation. This reduces the effect greatly, or cause it to disappear completely. This jerky then but of course when you play of NTSC-based frame rates.

No, this is inevitable is not. In "normal" PAL MPEG2 jerky streams namely nix. 8-)

Jepp - habs with my Eizo just tried: he eats while smoothly to 75Hz but s.der discontinuity of the pan / zoom can be I do not change. There is not content directly (niedrigfrequentes) Jerkiness but rather a higher discontinuity "of the movement. I can think of no more appropriate description. : - /

No, as already written, I can with SD streams in the 60Hz refresh rate is not normal Jerkiness found - neither in PAL or NTSC material.
What struck me, however, is:
I see me when you play in the MPC's "Properties" of the Video renderer, it will be expected to 25B / s as' medium Frame rate 'is displayed. Strangely there are during the Playback of HD transport streams to 33.5 Hz I am completely understand where the Koemm could.

Mistake on my part - the 75Hz can be adjusted while, but the Screen remains at "his" 60Hz (DVI wg.?)
The second screen can be set at 75Hz, but MPC refuses, then the h.264 stream represent - MPEG2 go there ...

I have the Cyberlink stuff deinstaliert times and the MPC to the Current Home Cinema version. This can be with their filtering brought the h.264 stream represent. The processor load is somewhat higher and jumping / scrolling a bit over the hooks Cyberlink filter, but the bucking is gone (!) And the 'medium Frame rate 'is now synonymous with the voices 50B / s displayed. :-)
Let's see what happens to me now for the DVBViewer invades ...

I can recommend CoreAVC (I currently use 1.7.0), unfortunately not free and still no GPU support, but together with DVBViewer 3.9.4 is very stable and smooth.
