I think there's confusion between video and e-book formats. The user might be looking for a way to access Hindi MP4 content on mobile devices (hence "mobi") and "best" refers to the best sites or methods for that. They could be referring to hindimp4.com as a website for downloading Hindi MP4 movies, and now want the best MOBI (mobile-optimized) version of that site or content for mobile access.
Wait, but MOBI can include images, maybe. But videos? Probably not. So maybe it's a case of confusing MOBI with MKV or MP4 formats for mobile viewing. The user might be looking for how to download Hindi MP4 videos (like movies) from a site called hindimp4.com and then convert them to MOBI for mobile devices. But that's not standard. Converting videos to MOBI isn't common. hindimp4 mobi best
First, "hindimp4" might be a typo. Maybe they meant "Hindi MP4"? Since "mobi" is a file format, maybe they're looking for a mobile-friendly or MOBI format of something related to Hindi MP4s. But "best" is part of the query too, so perhaps they want a list of the best MOBI files related to Hindi MP4 content? I think there's confusion between video and e-book formats
