Another angle: the user might be looking for a compact version that doesn't take too much space but still offers decent quality. So the 480p at 350MB could be a good balance. But they want to know the "best" between 480p and 720p. The review should address both scenarios: if the user prioritizes quality, the 720p could be better if the file is a reasonable size, but if they need portability, 480p might be better. However, if the 720p is only 350MB, it's probably not worth it due to lower bitrate.

First, I need to recall the movie itself. "Poseidon" is a disaster film based on the 1969 "The Poseidon Adventure." The original user might have seen it before and is looking to rewatch it in a higher quality format. They mentioned Hindi dual audio, so it's likely they want to switch between Hindi and English audio. That's a common feature in South Asian markets to accommodate both local language and original language preferences.

Be sure to download from reliable sources to ensure minimal quality loss and avoid piracy-related risks.

Also, considering the source is Bluray, but the user is asking for dual audio Hindi. The original movie is in English, so having a Hindi audio track is crucial for their audience. I should mention the availability of dual audio as a pro for the target demographic.
