user6843: I want to check is there any way to compare portion of video(video clip) with full video?
for example: if i have a particular video of scene in a movie and full movie video, how to check whether these clip belongs to that movie. if i have thousands of clips and thousands full movies, how can i find which clip belongs to which full video.

user13978: If the clips both have the same audio track, you can use audio fingerprinting techniques to identify them. Apart from that, OpenCV can do similarity checks on video: http://docs.opencv.org/2.4/doc/tutorials/highgui/video-input-psnr-ssim/video-input-psnr-ssim.html
And BTW. if using the audio fingerprinting method, as you can see with Shazam or musicbrainz.org seems to be managable from the amount of data.
