You got at least one thing wrong. Accel MA is at default. Too low… so if that’s wrong… And yea, forget the videos, we don’t need that. Log file or parameter file at a minimum. The log file may be worthless with the tether. Other than the parameter file can be extracted from it.
Loose the tether and do it right.
And sorry, Alt>A
I think the motors are too powerful for your small quad.
Was able to get another flight without the tether. I have uploaded all of the log files to my dropbox (link bellow). It still was oscillating slightly but MUCH more reasonable after using Alt A! Thank you for the help so far! I really appreciate it. I was thinking of running the copter in AutoTune mode, would this help kill more vibration? Thanks again!

It will probably reduce vibration, so I would run autotune in alt hold mode
This log us useless for analysis. It looks like you were running compass calibration.
Before running Auto Tune you need to configure the Dynamic Notch Filter. So set INS_LOG_BAT_MASK to 1. Make a Hover flight (get it off the ground a few m) for ~1 minute and post that log. Or read the Wiki and figure it out:

Update the firmware to latest Stable (4.0.7) before doing anything.
