VideoCapture capVideo;
capVideo.read(imgFrame2);
is there a limit on how many times I can use .read on the same file?

No. Why would there be a limit? You need to call `read` indefinitely when working with live camera sources, for example. – Dai Jan 11 '20 at 15:56

1Probably depends on what `capVideo` is. Hard to say anything if we don't know what function you are calling. – Lukas-T Jan 11 '20 at 16:03

There's no limit. Each time you call read function, new frame is returned unless there's an error (end of video file, error while capturing image from the camera etc).

so I can have like 10 read function reading from the same video file and use all 10 for different purposes? – Quattron Tech Jan 11 '20 at 15:58

Definitely. Remember that each time you call read different frame is returned. – Piotr Siekański Jan 11 '20 at 16:01

I don't understand what you mean by "different frame is returned"? – Quattron Tech Jan 11 '20 at 16:05
