Template:VideoGallery/sandbox/doc

Compare below and ! True randomization is our key feature. Requires JavaScript which I have provided a working sample in the talk page. Without JavaScript this will just display as hyperlinked list in reverse order. Another benefit is reducing editing required. Just copy/paste the video link and write caption!

Legacy compatibility
Videos like below still use the old template parameters, they will work fine.

Other rationale

 * Requires  to avoid issues with equal sign ("=") in template. If Problems is doing it then why not this?
 * Parameterless to prevent parameter typo or tampering. This has happened before. Can't remember where is our old discussion at, there was a delusional anonymous tampering the parameter number in attempt of having his video first on the list - in assumption of only the first three videos will embed on the page. This won't be the case when parameters weren't there. They can paste their url anywhere in the list, doesn't matter. Also with JS they wouldn't be thinking about the edit save grinding.
 * Quality categories added: checks if the video url is accepted for embedding and checks for the missing caption.
