Dear all,
I am extracting frames from a video stream of approximately 2 minutes at 25fps. Total size of the video is 4.4MB. I calculate size of individual frame as follows:
I convert the file size into KBytes(4.41024) and calculate size of individual frame in KBytes. (4.41024) / (120*25) = 1.5 KBytes (size of one frame)
In OpenCV, I get the following frame data: Rows: 288 Cols: 352 Channels: 3 Size: [352 x 288] step: 1056 (# of bytes occupied by each row)
If I calculate size of one frame in Bytes: 1056*288 =304128 Bytes = 297KB
Could you please comments on this size calculation and explain the difference of size?
Regards,
