Putting videos behind spoiler tag?

[ilum]

I've been wanting to post videos behind spoiler tags because they are very big in size but it doesn't seem to work for me. I saw someone else do it though. The way I do it is by clicking the spoiler button and then I upload a video via choose files but the video always posts outside of the tag. Is there some other way to do it? Do I have to upload the video to a website first and then post the html code inside the spoiler tag? Thank you to anyone who can help!

@Matt! thank you so much! I didn't realize you have to DRAG the video into the box. Now it works

 

Well done!
