In origami, no matter what shortcoding is used to resize embedded videos, the theme always scales them to maximum width. Switching to other themes shows that the vids scale according to the shortcode, but not on Origami. Very frustrating. Not a coder, so not really sure what else to try.
The issue you’re talking about should not happen, I’ve even re-tried shortcode-defined widths on the theme demo once more to make sure. The reason why the embedded videos have a maximum width is because if they wouldn’t, the videos would not resize correctly on browser resize, making the theme non-mobile-friendly in this respect.
No worries though, we’ll solve the problem. For the starter, could you please provide a URL of your website’s page with videos, I will have a look at the code?
