Kmay,
The Squats look pretty good. The knees do not travel forward after you are about halfway down (which is very good), but there is a little bit of a cave-in at the bottom. (just really think "knees out"). Your stance may be just a bit wide, but only a bit.
From the side view, the only thing that is not very apparent is the hip drive. Focus on keeping the "chest-up" but think about driving the hips towards the ceiling.
Otherwise pretty good.
Deadlift there are some problems. First, why aren't you deadlifting at the gym when you squat?
Once your feet are under the bar, do not let the bar roll back and forth..
Your shoulder should be in front of the bar not directly above the bar (see, for example, 00:35).
Lift your chest hard before the pull. That will set your back.
Do not release your breath at the top...at the beginning of the descent it looks like your whole body collapses (00:39), certainly the release of all that intra-abdominal pressure from breathing out starts this collapse.
Let's start there.
