If you’d like to share an Instagram video on Pinterest, you can simply grab the URL from Instagram via your browser and paste it into the “Add a pin from a website window in Pinterest. I had a problem doing this on my Mac so I tried an alternate method.
Here’s how I did it:
Open Instagram on a browser and select the video you’d like to share.
Click on the icon with the three dots in a row at the bottom right of the window:
Click on Embed.
Click on the green Copy Embed Code button and paste the contents into a notepad. Delete everything except the partial URL as indicate in blue below.
Key in the missing “http:” to the beginning of the URL. Once you’ve done this, select the whole URL (i.e. http://instagram.com/p/xxxxxxxxxx) and paste that on the Pinterest window.
I hope this has helped!
