I will be honest. I am not technologically savvy. And when we did prescreens in 2012 (for a D who graduated HS in 2013), we hired one of Ds friends (a high school student) who filmed everything for us and edited it all together for each school the way they needed to be, providing us with the files in the right format for each school. It saved me a lot of stress since I didn’t know how to do it myself.
Phones have much better capability now than they did even 5 years ago. But I agree with all - we didn’t do anything super fancy. Don’t waste money on any sort of fancy filming. But also don’t feel bad if you need to get some help. We hired someone because I wanted to make sure we got recorded what needed to be in the formats needed. It was $100 well spent.
