“im using your wordpress theme- how do u adjust size of image (or video)” at theaudiodistillery.com
Answer 1: I don’t use a header on that site. It’s all a background picture and I made the header inactive.
Answer 2: I took a look at your site and the video on that page. You need to adjust the size of that hero container to fit the image, or edit the image to fit the format of that container.
I rendered my video to 1800*300 for my header at perfectstrangersrising.com. However, I also edited the video timeline in same format 1800*300 so that I could crop the shots and get what I wanted in the header, instead of mid body shots with heads cut off etc. It was hit and miss and I settled for 1800*300. I tried many times in different resolutions, just keep experimenting. Different resolutions will work depending on what you are trying to to accomplish. I tried the recommended settings in WP and it never worked out.
