Hi group!

On an exceptional weekend, instead of studying I went skiing. Long story 
short, four commands on the command line and about one hour (I did not time 
the process and I did not attend it) later:
<http://vimeo.com/88614631>

The commands:

/home/yuv/bin/ffmpeg -i 00110.MTS -deinterlace -f mp4 -vcodec libx264 -crf 22 
-preset ultrafast -s hd1080 -strict experimental -acodec aac -b 25000k -ab 160k 
-ar 44100 -ac 2 00110.mp4
transcode -J stabilize=shakiness=8:show=1,preview -i 00110.mp4 -y null,null -o 
dummy
transcode -J transform -i 00110.mp4 -o stab.avi -y raw
/home/yuv/bin/ffmpeg -i stab.avi -f mp4 -vcodec libx264 -crf 22 -preset slow -s 
hd720 -strict experimental -acodec aac -b:v 10000k -ab 160k -ar 44100 -ac 2 
upload.mp4


The flow is really nice, especially compared with the shakiness of the 
original (the highest priority was not to bump into others while skiing 
backward), but it seems that during some sequences it placed bad control 
points (on the subject in motion), resulting in "subject-jitter". The 
options of the first transcode command visualize the selected control 
points.

The question is: given the sequence of individual frames, can cpfind do 
better at setting CPs only on the background and not on moving subjects? I 
suspect yes.

The corollary question is then: can it be integrated into transcode 
<http://www.transcoding.org/> or into ffmpeg <http://www.ffmpeg.org/>?
