Very nice picture quality. But why the hell do even professional film makers have absolutely no clue how to set up a Microphone for recordings? Either they are stupid or they should visit a Doctor to check their ears. Believing that the human ear hears sounds distorted when they are loud is just so... stupid that it hurts everytime I must hear that
They had the oportunity to get fabulous, clean recordings of a flat six. But they don´t even tried to (or even worse: They had a perfect recording and distorted it in post processing).
Maybe you are right and they just had a Cam with top notch picture Quality, but a bad microphone. This one is exactly the opposite. Crap picture (maybe due to compression and not the cam), but a clear sound.
The best is if you have a Cam or Audio recording device which lets you adjust the input Level. Then you can make some impressive sounds with a high dynamic range. Listening to such recordings with state of the art playback equipment is nearly like being there But that costs some money... did some recordings in the past with a "artificial head" like Microphone. That´s impressive.
