Tips: how to find out the name of a deleted YouTube video

Sometimes, when a video on YouTube gets deleted, you may have only the address saved, but not the title.
For example, you may want to remember what was that deleted video in your "Liked videos" on YouTube about.

First of all, you need to find out the ID of that video;
it's quite easy to retrieve it from the URL of that video.

E. g., here is a sample short link:
https://youtu.be/RemV1deo_ID
And a "canonical" long one:
https://www.youtube.com/watch?v=RemV1deo_ID
And "RemV1deo_ID" is the target 11-character video ID.

Unfortunately, the search itself is not so simple...
Sometimes, the deleted video page still preserves the video title.
Otherwise, try searching the ID in YouTube, and then in plain Google (and any other search engines you like): often, some sites embed, link or otherwise mention YouTube videos (searching full links is not much better, but you can also give it a try).

If the video has been recently deleted, you can try some "special" Google search syntax, e. g.:
cache:https://www.youtube.com/watch?v=RemV1deo_ID (Google cache)
and
info:https://www.youtube.com/watch?v=RemV1deo_ID (Google page info).

Have a good luck & enjoy!
