To save a grayscale video in Windows 10 and Python 3.7, I added the clause "isColor=False" when constructing the following line: "out = cv2.VideoWriter(filename, video_type_cv2, fps, my_res, isColor=False)". Worked like a charm!
Also, good quality tutorial and demonstrations, I appreciate it.

Is is possible to have a certain amount of time for your video to be recorded? like you want to record a 1-3 minutes video and then break the loop. Is is possible? Love you hear your feedback and how you do it :)

Thank you Justin. Is there any way to apply face recognition not by using the camera but in the screen?
For example when you're having a video call in WhatsApp Web and you want to run the program to recognise who's in the call

Can I use this records for IP camera ?

[HollyDiFifa]

Hi, what do I need to edit to record video from a camera (not webcam)?
I know the IP of the cam, and I can transmit on the PC what it frames (I should save the video)

Hey thank you so much for sharing this amazing video. Does anyone know how to recorde audio along with video. I am able to record videos but it doesn't have any sound/audio in it. Thank you :)

[ferdousazamkhan]

Hi, great works. I use linux mint/ubuntu. Adding linux references beside mac & windows would be helpful for more and more people like me. Please consider. Thank you

Great video !! But there is a problem .... I dont know why i can save and play the video when using 480p, if i enter 720p or other else, it only save the output but cant play the video.
FOR THOSE WHO CANT PLAY THE VIDEO, TRY TO SET IT 480p MAYBE IT WILL WORK.
