How to get the video links? Here it is!
1. On the PC / Mac:
Right-click on the date of the video or photo on Instagram, then select “Copy Link Address” to download the Instagram video on your desktop. You can also directly copy the page URL.
It should look similar to this example: https://www.instagram.com/p/123456/
2. On the Instagram app:
To copy the Instagram photo URL on iOS, tap “Get the Instagram photo URL” above the post, or on Android, select “Copy the Instagram URL.” Then, choose “Copy Share URL.” The link will be saved to your clipboard.
