I have a video sequence composed of 3076 frames.
The original video at 10fps lasts 307.6 seconds (or 5.12 minutes).
I want to convert the video in order to last 1.42 seconds at 29.98fps using Python OpenCV.
How to accomplish this task?

why opencv? is the video an existing file or being created in opencv? – Paritosh Singh Jan 01 '19 at 13:56

2You're not trying to reduce fps. You're trying to increase fps. – Employee Jan 01 '19 at 16:32

1IMHO a computer vision library is not the ideal tool for something that most likely involves just changing a few bytes in the header of the video file. – Dan Mašek Jan 01 '19 at 17:37

1I would have expected a 3,076 frame video to last 307 seconds at 10 fps not 5.12 seconds. – Mark Setchell Jan 08 '19 at 10:19

You can use cv2.VideoWriter function where you can adjust fps as per your requirement.
More details about the function open CV video saver
out = cv2.VideoWriter(str(videoname+"AV.avi"),cv2.VideoWriter_fourcc('X','V','I','D'), fps, (fw,fh))
