There is a issue I'm facing regarding saving a video. I currently have a camera that can capture up to 120fps. When I recorded a 10s video, the video duration was being cut by half and The video looks like it's being sped up.
The specs of my camera: https://m.aliexpress.com/item-desc/32363729557.html
I have written my code in python as follow:
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
fourcc = cv2.VideoWriter_fourcc(*'MJPG')
out = cv2.VideoWriter('output004.mjpg',fourcc, 120, (640,480))
while(cap.isOpened()):
ret, frame = cap.read()
if ret==True:
frame = cv2.flip(frame,0)
out.write(frame)
cv2.imshow('frame',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
else:
break
cap.release()
out.release()
cv2.destroyAllWindows()
