Video stabilization using VidStab and FFMPEG
Vidstab is a video stabilization library which can be plugged-in with Ffmpeg and Transcode.
"A video acquired using a hand-held camera or a camera mounted on a vehicle, typically suffers from undesirable shakes and jitters. Activities such as surfing, skiing, riding and walking while shooting videos are especially prone to erratic camera shakes. Vidstab targets these video contents to help create smoother and stable videos."
