vStab

KLT Video Stabilizer

Video stabilizer for CCD and CMOS cameras based on the Kanade-Lucas-Tomasi feature tracker.

Characteristics and limitations

• Only the panning movement will be corrected

• Only the AVI/MJPEG video format is supported

• The witdh and height in pixel of the video file must be multiples of 16

Usage examples

Sony PSP as the video source

The included Blender Avilib can read and write PSP-compatible video files directly, however since the GO!CAM employs a CMOS sensor it is necessary to specify a shutter angle on the command line. Acoording of my tests PSP's GO!CAM always uses the full 180 degrees regardless on the quality setting, so:

./stab -r 180 <input>.AVI <output>.avi

Will hopefully give the expected result.

Analog video as the video source

Acquire from the capture card with ffmpeg and a command line like:

ffmpeg \

-y -sws_flags lanczos -deinterlace \

-f video4linux2 -s 768x576 -r 25 -i /dev/video0 \

-f alsa -ar 44100 -ac 2 -i default \

-croptop 4 -cropbottom 4 -cropleft 4 -cropright 4 \

-s 640x352 -vcodec mjpeg -qmax 1 \

-acodec pcm_s16le \

capture.avi

And then process with:

./stab capture.avi <output>.avi
