I'm working on proofing my video which contains a bunch of
ken-burns style photo pans and zooms using the Pan/Crop
event feature in 4.0e.
I have a lot of these (15 or so) and I've been checking each one
carefully before I finalize the project and I've noticed something
strange. Right at a keyframe that begins a pan with a slight
resize the result jumps down and to the right about 1.5 pixels,
this happens in the next keyframe and the third. The result is that
in 3 frames the image has jerked about 5 pixels and this is
BEFORE my programmed linear pan with 100 smooth starts to
take effect. It should be a very smooth pan but instead what I
have is a perceptable jerk that starts what becomes a nice
smooth pan.
I don't have two keyframes right next to each other to cause
this jerk. There are just two key frames in the whole event:
one that marks the beginning of the pan and at the end.
Lastly, during the "jerk" none of the Size/Center/Angle numbers
are changing so I don't know what my picture is moving.
I have resample set to "Best" and I have set video supersampling
to 6. The same jerk is still there.
