[Noah Kadner] "Yes obvious to a considerable degree but if it's a "crash camera" people expect it to look different from the main camera especially in sports."
You can make that difference work for you. It becomes a visual cue that you're using the 'helmet cam', 'handlebar cam', or whatever, giving it a different, more immediate feel to the viewer.
