Personally I detest uploading videos to eBay as they clearly are throttling the speed as its way too slow.
I instead upload them to YouTube and embed them using the website below.
YouTube or Vimeo Code Converter for eBay 2018 - 2022 (isdntek.com)
The code this site creates is the same each time aside from the links to the YouTube video so you can alternatively just use a AppleScript I created t o generate the code.
(1) Go to YouTube and copy the shareable link to your computer’s clipboard.
(2) Double click AppleScript.
(3) A Dialog will be displayed into which you paste the shareable link and click the “Continue” button.
(4) A second dialog will be displayed with the default value “Watch Video”. This is a short caption that is placed on the top left corner of the video’s screen grab. If you want to use the default press the “Continue” button. If you do not want a caption delete the default text (which is already selected) and then press the “Continue” button. If you want to use another caption, such as your eBay username, type it in and press the “Continue” button.
(5) The assembled code is copied to your clipboard for pasting into GS’s HTML view.
Modify the AppleScript below as needed.
Please note that a " or \ symbol in the EmbedCode string has to be escaped with backslash such as \" or \\ or you will get an error so be careful about any edits.
