Video height and weight

Video height and weight

I'm trying create a site where there are multiple on video on one page,
basically a new video will be on the bottom after one like the image shown
below.
This is a two separate video, the problem is i cant find a way for all the
video to have a standard size. both video has same width and height, here
is the snippet:
src="file://D:/src1.mp4"
tabindex = "0" controls = "controls" loop ="true
width="320" height="240">
src="file://D:/src2.mp4"
tabindex = "0" controls = "controls" loop ="true
width="320" height="240">
What i just want it for both of them to have the same size. Note: I not
yet eligible to post an image
