I have to be careful with proper nouns like the file name "042816-550 .mp4" and ensure they remain untouched. Also, the user mentioned in the previous interaction to skip brands and names, so proper nouns here are part of that. Need to check if the file name is considered a proper noun here. Since it's in quotes and has a specific name, I should leave it as is.
