Any player, any site
YouTube, Netflix, Bilibili, VLC, IINA, a lecture recording. If you can see the words, you can look them up.
For video and subtitles
Subtitles are drawn onto the picture, so no dictionary can select them. AALookup reads what's on the screen. Pause, point at the word, and the meaning of that line appears next to it. Any player, any streaming site, in a browser or an app.
No account needed. Your dictionaries stay on your computer.
