The link with video is down. Wanted to see again
To what Luts you where refering that bring a more "Alexa-like"?
A high pass filter of like 150 to 300hz, or Wind cut filter in the camera settings could help very much too to reduce noise and mudness in the audio.
Some DVD authoring tools do that, and virtualdub with some plugins too with avi files.
there is apps like DivXLand Media Subtitler too. But I havent used them recently.
