1. I filmed myself and I used my A roll videos, I edited my video on capcut. I cut out parts where I messed up on and some parts I felt like shouldn't include. I added B roll into it to fix it up a bit and I made sure that the timeline was over 45 seconds. 
2. A video resume is like a trailer of your skills and experience. Instead of using paper you showcase your qualifications through a video presentation. It allows employers to see and hear you giving a more personalized impression compared to a traditional paper resume.
3. I might use this for future jobs I apply to.

4. I think the level of mastery on my resume video is a 4 because I really tried my best to do this and make it look nice.
