Best advice to start with is use what you already have. Your phone probably has a pretty decent camera for videos etc.
When I started podcasting and videos it was all done through my phone. Videos recorded and uploaded to YouTube. Podcasts recorded on an app.
As I got more into the hobby I expanded my equipment. I now video using 3 cameras. A Sony camcorder a Sony dslr camera and a go pro. I then recorded audio separately on a zoom h1 audio recorder.
The podcasts are now recorded on my laptop with audacity software with a Samson microphone. For on the go recording I use my zoom again.
In the future I might do a little video going through this but if you want to email me please go right ahead.
