この動画を見る時は、部屋を明るくして離れて見てくださいって英語でなんて言うの？

To break up the sentence: - 明るくして = well-lit area ; - 離れて見てください = watch from a safe distance Put it all together and you have "Please watch in a well-lit area from a safe distance." You could also say: - "Be sure to watch in a well-lit place, not too close to the screen." "Place" is another way to say "area" and "not too close to the screen" is more casual than "from a safe distance." If you want to treat the message like a reminder, you can say: - "Remember to keep the lights on and don't sit too close!" This is the most casual of the three phrases. When you say "don't sit too close" it is implied that you mean "don't sit too close (to the screen)."

Please watch this video in a well lit area- This politely asks them to watch it in a bright place Watch this video in a well lit area for the best results - tells them that they can watch it anywhere but it will be better for them to watch it in a bright area

This is a simple, straight forward sentence. 'watched' or 'viewed' mean the same thing. 'best watched/viewed'- for best quality. I hope this helps :)

1. Here, you are politely identifying that the recommended way of proceeding with viewing the video is to ensure there is ample lighting in that area. "Way are you opening the curtains, dad?" "Well, it's recommended that we watch this video in a well-lit room." "Ah." 2. It's advisable = this identifies the best way to do something so as to achieve a satisfactory result. "It's advisable that you study hard if you wish to pass your exam!"

You can start your statement by using the adverb 'please' to express politeness if you want your request to achieve positive results. Most people view politeness as a virtue. In the second request, you have used the adverb 'brightly' instead of 'well-lit'. The adverb 'brightly' in this context means 'in a way that gives out or reflects a lot of light'. You may also give your message in a negative format by warning your audience not to watch the video in a dark room. By doing this, you are indirectly telling them to watch the video in a brightly lit room for good results. So, you may say: Please watch this video in a well-lit room. or Please watch this video in a brightly lit room. or Caution: Do not watch this video in a dark room.

A well lit room means that it is bright and there is alot of light in it When expaining to someone that it is better to watch the video in a well lit room then you would say 'for better viewing' or 'for best results'

If you want to insert a message at the beginning of a YouTube video stating that people watching should watch in a well-lit room, you can say: "Please ensure that you watch this video in a well-lit area." "Make sure you are watching this in a well-lit room."
