Hi,
I have some skiing footage with slow background pans of the mountains as well
as fast foreground pans of skiers. The camcorder is handheld and there are
some jerky shakes that make the footage quite difficult to watch.
I tried to use y4mstabilizer to fix them, but it seems to follow the panning
motion in both cases, rather than just removing the high frequency shakes. I
also do not have any free horizontal crop space, so I only want to remove the
vertical judders.
My command line is:
lav2yuv pan.mov | \
y4mscaler -v 0 -O chromass=444 | \
y4mstabilizer -v 0 -r 10 -a 0.7:0.9 | \
y4mscaler -v 0 -O chromass=420_MPEG2 | \
yuvplay -v 0
I've tried various "r" values and "a=xx:yy" combinations, but nothing
focuses on just the shaking.
Any ideas?
Alec
