I don't think it matters what I think, as I am most likely not your target audience, but for the record, I do think that no matter what, you have to do the very best you can. If you did all you could in the scripting and filming of the video, but have some blur or "hissing noise", does it really matter? Hell no. You can't afford a better camera, right? So why blame yourself for something you can't fix right now? If you were just downright lazy and spent a whole 10 minutes on it, yeah, that's on you. But it sounds like you put some time into your content, so do yourself a favor and forget about it. If people don't like your video for your equipment, their loss.
