Hi, I am using opencv VideoCapture() method and imutils VideoStream() functions to capture video from webcam. This two functions output is different. Position of the camera is fixed. However coverage area differs a lot. what functionality behind this functions? I can set the frame resolution in VideoCapture(). Likewise how to set frame resolution in imutils VideoStream()? ---

> [@Maheswari.R](#): > > imutils VideoStream() Hi, May be somebody can help you about imutils but this forum is about opencv. You can explore source code too I think it’s [here](https://github.com/jrosebr1/imutils/tree/master/imutils/video) ---

ok @laurent.berger. thank you ---

`VideoStream()` can use `VideoCapture()` or `PiCamera()` (on Raspberry Pi) and it runs in thread so it can run faster. In source code you can see it uses `resolution=(320, 240)` and this may change output but only for `PiCamera`. For `VideoCapture()` it should use default resolution. You would have to show code which you use. Maybe you set different resolutin in `VideoCapture` and you use non-default value. ---

Thanks @furas . I have set the resolution(1920, 1080) of VideoCapture. But not for videostream. I think it’s taking default resolution. How to set the resolution in videostream? ---

I don’t see any method to set resolution for **VideoCapture** in **VideoStream** It assigns **VideoCapture** to **VideoStream.stream** so you may try to use ``` s = VideoStream() s.stream.set(cv2.CAP_PROP_FRAME_WIDTH, 1920) s.stream.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080) ``` but `s.stream` is already reading one frame and I don’t know if you can change resolution during reading frames. Eventually: **VideoStream** uses class **WebCamVideoStream** which uses **VideoCapture** - so you can copy source code of **WebCamVideoStream** add `set()` in ` __init__ ` before first `.read()` in this class and use this **WebCamVideoStream** instead of **VideoStream** [imutils/webcamvideostream.py at master · jrosebr1/imutils · GitHub](https://github.com/jrosebr1/imutils/blob/master/imutils/video/webcamvideostream.py) ---

I would strongly suggest seeking support for imutils from the imutils author, on the given github. he knows best what his library is doing. ---

> [@furas](#): > > **WebCamVideoStream** I have tried the above method. but it didn’t change width and height. ---

ok @crackwitz . I will post the question in github imutils page ---

The VideoStream class can be constructed with the new resolution. > VideoStream(src=0, usePiCamera=False, resolution=(320, 240), framerate=32, \*\*kwargs) ---
