Frage von Martyrium:
Hi,
Another problem:
I have footage of a camera panning in the horizontal direction. The Picture has been stabilized, but the cameraman was probably not such a steady hand, or a cheap tripod:
The swing takes place very irregularly, falters a little, sometimes a little faster sometimes a little slower.
Is there a way to make the motion smoother and more evenly to linearize the quasi-turn?
Obviously, there seem to be tracking on opportunities to give, because I have found the content of specifying a Video2Brain videos, is reported in which of these issues:
"Linearize hand swing
Hand panning contribute not only shaky, but synonymous restless, because the swing speed does not
is uniform. But here you can synonymous with the Stabilizer function for a significant relief of the
Recording care and subsequently linearize the camera movement. "

Antwort von Mylenium:
If in doubt, with expressions ... Somehow, the average speed of the tracker and then calculate the actual speed frame by frame with an adaptive factor to multiply and with Timewarp And so wired, based on the difference to recycled. Should we try it. is only so'ne idea how I do it wüprde .... You could, of course, synonymous simply buy the DVD, then you know it very well. ;-) Maybe I am thinking too complicated.

Antwort von Blackeagle123:
The procedure is quite simple:
The Picture is enlarged and s.hand various points in the Picture, it determines the "swing speed". If the pan speed too much from (tolerance adjustable), for example by a stuttering, the picture shifted so that one has the feeling that it was a quiet swing.
Picture is choppy too much, it would have to increase greatly, which has a huge quality loss.
As a plug-in is available for Premiere Pro SteadyMove of 2d3, there's a tutorial:

Außerdem kann man with AfterFX of Haus aus das Video stabilisieren with dem Keyframe-Assistenten. Das Problem ist, dass das Picture nicht ruhig stehen soll, sondern in "linearer Richtung" ruhig
to run. Therefore, it should really work with expressions, or another plugin.
Hope you have helped him.
Best regards,
