"video:false" or "video:true" have nothing to do with the videos attached to the movie.

To get the videos, you should use the Get Videos method of the API.

How to get movie trailers

• When I request a specific movie, I usually get "video: false". Would there appear a trailer if it was available?
  
• When I look up a movie on TMDB website, there is a trailer linked (
  e.g. https://www.themoviedb.org/movie/550-fight-club#play=G7tr7xcUCFA).
  How can I get this YouTube ID within the API?
  Thanks

The meaning of the Video attribute, in the singular, can be seen here:
https://www.themoviedb.org/bible/movie#59f73b759251416e71000005
Roughly identifies what is not Movie.

The Videos parameter, in the plural, refers to trailers and other videos of the same type.
See here: https://www.themoviedb.org/bible/movie/59f3b16d9251414f2000000a
To get the Videos of a Movie, See here:

1 - https://api.themoviedb.org/3/movie/550/videos?api_key=THE_KEY

Trailer URL

When you make an API Request requesting Videos (plural), in the response you will receive something like this:

videos  
results 
0   
iso_639_1   "en"
iso_3166_1  "US"
name    "Fight Club - Theatrical Trailer Remastered in HD"
key "6JnN1DmbqoU"
site    "YouTube"
size    1080
type    "Trailer"
official    false
published_at    "2015-02-26T03:19:25.000Z"
id  "5e382d1b4ca676001453826d"

Just add the Key in the respective URL:

YouTube: https://www.youtube.com/watch?v=  
Vimeo: https://vimeo.com/  

For example:
Youtube: https://www.youtube.com/watch?v=6JnN1DmbqoU
Youtube: https://www.youtube.com/watch?v=hzfvYSIIgyc
Vimeo: https://vimeo.com/282875052

Hi @user, we only support YouTube and Vimeo right now.

Thanks, that helped!

Please, the videos are not corresponding to the movie ID's

Without the exact query (just remove your API key) you have sent and the answer you have got, we can't help you.

This is it https://api.themoviedb.org/3/movie/61222/videos?api_key=${API_KEY} the ID "61222" is from the API, and it belongs to a movie known as "Bojack Horseman" but when I fetch the API above it returns a video trailer name known as "Home Trailer"

This is the response in JSON:

0:
 id: "533ec6b7c3a36854480063c0"
iso_639_1: "en"

Bojack Horseman is not a movie. It's a TV Series.
BoJack Horseman (2014)
https://www.themoviedb.org/tv/61222-bojack-horseman
Home (2008)
https://www.themoviedb.org/movie/61222-home

Oh okay, I see. Now I have to find a way to differentiate the series from the movies. Maybe, I can use some help to know if there's a way to filter the full movies from the series

One way would be to query the movie and tv details pages to see if the id exists and see which one the title matches if they both exist.

Another possibility would be to download the daily file exports to get the list of ids for all titles.

I guess I am wondering where you are getting the id numbers you want to use and why isn't there something from the source of the ids that tells what it is?

Thanks a lot @robbie3999 I finally figured it out
